I have a new pair of Sidi shoes and am considering going from Lookpedals to either Campy Record Pro-Fit Plus or Shimano DuraAce SPD-SL's.Which, if either, will work better with the Sidi sole and plate? Will I need to get longer cleat bolts for either system?  Will I needto use the Sidi plate with either system?How about Sidi with Ritchey Road pedals?  (I understand the Ritcheycleat is a 2-hole SPD style.) --PhilDear Phil;For the Campy or new Shimano SPD-SL pedals, you will use the sameSidi plate you did with the Looks, and both pedals will work identicallywith that shoe as the Looks did.

While not one to complain about the goings-on at other cycling publications, I'm about to (briefly). Two weeks ago Manitou presented the media with a sneak-peek at its 2004 product line which we lightly reported on, but I adhered to the requested black

Wow, it's been a whirlwind of activity around here. I won't bore you with the down-and-dirty details of trying to push our 2003 Buyer's Guide out the door (I'm beginning to think of it as one of those drunk party guests that refuses to leave your house at 3:30 a.m. when everyone else has split). Instead let's stick to the part where I tell you how I just got back in from a weekend of riding with the Manitou boys down in sunny Phoenix, Arizona. Perfect timing to sneak away from the near zero cold snap that had Boulder firmly in its grasp. Unlike most manufacturers, Manitou chooses to show

I have a question regarding race radios. We have an elite/pro Canadian team that we are just starting up. I have been doing a bunch of research on which race radios are the best for use for our team. I find it strange how little information I can find on this topic. We have tested a few different options and we seem to be coming up short in our quest for a good solution. We have tried the Motorola FRS type radios - they only work when our riders are very close together. If we have one guy up the road they fail miserably. We then tried more robust, higher power radios, which had a better range

QuestionI recently purchased an NOS Time/Look carbon fork to put on my '87 Paramount. I am running a 2002 Record triple group and am wondering about the mounting of the front brake caliper on the fork. With the steel fork I was not worried about the washer with the "teeth" on both sides biting into the fork, as that is what it is designed to do. However, with my carbon fork there is no aluminum plate to mount the brake against and I am wondering if it is smart to use this washer? Will it possibly case problems biting into the composite material? If not this washer, then what should I use to

Don’t tell anyone, but I managed to sneak away from the tidal wave that is the VeloNews 2003 Buyer's Guide. We've been building this monster since early December, and with any luck, we'll have it out the door in two weeks (in your hands at the beginning of March). So far, so good I'd have to say. Even if you're not in the market for a new bike, components or accessories (do I see any hands out there?) I'm sure you'll find the numerous interviews with pro riders and their personal racing setups interesting. We even threw-in a few interviews with a handful of bicycle racing's biggest names

Dear Lennard Zinn;We've been looking around for a good road bike for my girlfriend andone thing we've noticed is that the Shimano STI shifters do not fit herparticularly well. She has relatively small hands and the levers are justtoo far away from the bar for her to comfortably brake. I believe thatShimano addressed this issue in the mountain bike brake set up, but dothey or anyone else address it in the road arena? --MikeDear Mike;There is no alternative, short brake lever from Campagnolo or Shimanowith an integrated shift lever like ErgoPower or STI in it. You can addressit with the

Dear Lennard Zinn;My question has to do with Campy Record 10-speed rear derailleur and cog compatibility. My current setup has 53x39 chainrings, a 12x25 cogset with a short (standard) cage rear derailleur, and I recently switched to a Wipperman 10-speed chain. For mountain riding, I would like to substitute a cogset with a larger inside cog - say, 26 to 29 teeth - rather than switching to a triple chainring setup. How high can I go before I have to use a medium or long cage derailleur? Also, for cost considerations, is there any problem using a Chorus 10-speed cogset if the rest of the

With the Holidays behind us it's officially Buyer's Guide season around here and we're working fast-and-furious to produce the most interesting guide you've ever flipped through. Whether you're in the market for a new bike or not, we've planned plenty of engaging copy to pique your interest in the latest product trends in bicycles, wheels, forks, stems, handlebars and a few other critical categories. But unlike any other bike-related Buyer's Guide that has been produced, ours isn't designed to denigrate your intelligence with features such as: "How to buy your

That sweet position on your road bike should be as comfortable as your favorite pair of slippers — and once you find it, you won’t want to give it up. But discovering the perfect position in the first place often requires many tiny adjustments in the height and reach of your handlebar to get it right. In the current issue of VeloNews, technical writer Lennard Zinn helps you work through the steps necessary to find that perfect position. As mentioned in the article, Alan Hills of Hills-Scientific.com in Boulder, Colorado, has shared a handy program he designed to choose the stems for his

Transplanted from California less than a year ago (there, it's official, everyone in Colorado can now hate me) the guys here at the office say the winter has been unusually mild. My early morning frozen water bottles and icy trails might disagree, but hey, at least we're out there and not relegated to the trainer (like I was told I would be before moving out here). Weather aside, the racing/product seasons are right around the corner and we're gearing-up for some pretty hectic travel schedules. For racing coverage, Jason's off to Malaysia, Charles is heading over 'cross

I would like to buy a pair to improvemy technique. Thanks for your help. --HeltonDear Helton;PowerCranks are cranks with a clutch bearing at the bottom-bracketconnection in order to only engage the bottom bracket in the forward direction.You can only keep them turning if you pull up and around the entire

A question that I receive often through my "Tech Q&A" column on thissite is how one should remove a seatpost that is stuck in a frame. Ratherthan answer each one, I can simply reprint the section from Chapter 10of "Zinn and the Art of Mountain Bike Maintenance" that touches on thatvery subject.Removing a seatpost that has frustrated all normal methods of removingit is a difficult job requiring lots of attention and skill because ofthe risk involved. This may be a job best done by a shop, because if youmake a mistake you run the risk of destroying your frame. If you’re not100-percent confident

Dear Lennard ZinnI'm 50 and have arthritis in my left hip. I've been riding a pretty laid-back road bike for years (A LeMond with a 72.5 seat angle, seat all the way back)I do Yoga regularly, and that has helped, but my hips ache when I ride. I’m wondering if sitting further back might be "working" my hips more. The second part is that I have another frame I could have built up, but it's radically different: 73.5 seat, 40.5 stays. The front end is almost the same as the LeMond. Both bikes are steel, the other frame is 753. I'm 6'2" and weigh240. Some people have said the shorter bike would

Well, things are certainly back up-to-speed here at the magazine after the holidays. I hope you had a good one. You'll be glad to know that even though we're all a little teary-eyed over Jeremy "Showtime" McGrath's sudden retirement, we're still focused on getting another issue out the door. It's NORBA's 20th anniversary and in the spirit of celebrating, we're working on a pretty interesting feature piece highlighting the highs (and some lows) of the governing body of mountain biking.Personally, I'm working on a few techy pieces that highlight just how far technology has come in the past 20

Dear Lennard Zinn; My right foot (third and fourth toes especially) goes to sleep after only a short time on the bike (10-15 minutes).  I've had the problem for quite a while, but just got new shoes (with plenty of toe room) and it's back - these shoes are stiffer than my others too.  If I stand or unclip for a few seconds it helps, but comes right back.  I use the same MTB shoes for road and MTB riding (recreational) - the problem is worse on the road.  What can I do to help?  --JeffAnswer: It sounds like perhaps you need custom orthotics. I have a similar problem, which in my case was

Dear Lennard Zinn;Everyone knows you don't have to work as hard if you're drafting off the person in front of you. How does your work effort change if someone is drafting behind you?Here is why I ask: I always thought that if you were riding by yourself, then you had to work harder than if somebody was drafting behind you because as you move through the air, it flows past your bike and body and creates turbulence as it swirls around in the void of space behind you. This almost creates a suction behind you pulling you back against your forward progress (if my logic is correct).

One of the more frequent questions I get on my “Tech Q&A" column is why Campagnolo changed its 10-speed chain and eliminated the PermaLink and, therefore, the tool to install it, now requiring the purchase of a different chain tool. In late July, I visited Campagnolo in Vicenza, Italy, and I got the answer to this question directly from Mario Meggiolan, the engineer who designed the new chain tool as well as the carbon Hyperon wheel. Campagnolo first supplied the PermaLink with 10-speed chains because that was the best way it could see at the time to make such a narrow chain strong enough.

The U.S. distributor of Look Cycling products, Veltec Sports, has issued a voluntary recall of the French manufacturer’s “Carbostem” handlebar stems. According to a Veltec release issued Friday, there have been no accidents or injuries involving any of the stems, but Look has reported that the stems, constructed of carbon fiber and aluminum, are subject to failure as a result of fatigue. Obviously, if that were to occur, a rider could lose control and crash. Therefore, Veltec is overseeing a full recall of the small number of stems distributed in the U.S. Veltec’s vice president of

Watch your head, because the component war continues to wage at full-fury. First, with Shimano's intentional/accidental shot over the bow with its posterboy Armstrong showing up all big and beautiful in the latest Sports Illustrated sporting next-gen Dura-Ace. And now with Campagnolo granting VeloNews the first detailed images of its much-rumored electronic gruppo. Our visit to Campagnolo world headquarters in Vicenza, Italy last week (look for a full report in two weeks) certainly helped smooth-out the tight-lipped policy that Campagnolo has so far held about any official comment about

With the racing off-season in full bloom, the past two weeks provided a short window of opportunity to sneak out of the office. But unlike a leisurely jaunt to ride the back roads of Tucson or a few days railing Fruita singletrack, we needed to get some work done (so said the boss). With a week's notice, I was told I needed to, "Pack my bags and grab as many notebooks as I could," because we were off to Italy for a manufacturer meet-and-greet. Part social call, part product fact-finding tour, this trip provided the opportunity to introduce myself to a good segment of the Italian manufacturers

The Interbike International Bicycle Expo is wrapping up in Las Vegas Tuesday afternoon. As VeloNews editors fold up their laptops and lend a hand breaking down our booth, we thought we’d put up a few more shots of items that caught our interest today. Cervelo – When the Toronto-based frame builder signed on as bike sponsor of the CSC-Tiscali team, Cervelo earned the distinction of being the smallest manufacturer supplying the Division 1 peloton. The company doesn’t reveal its precise numbers, but its safe to say that annual production is somewhere in the mid-four figures. Precise numbers or

It's been almost a full year since Manitou (in conjunction with Cane Creek, RaceFace, and Chris King) unveiled the evolutionary OnePointFive standard. And while most of the initial gee-whiz (or so-what?) factor has worn off, most of us are left wondering how an oversize headset, steerer and stem (not to mention frame) will really improve our riding? We’ve seen an increasing number of manufacturers producing OnePointFive standard components and forks, (a surprise move with once-skeptical Marzocchi adopting the standard) but most of us are still searching for some harder reasoning to

The 60th annual Milan International Bicycle Show fulfilled expectations of beautiful Italian designs in bicycles, components and soft goods. It also exceeded expectations of visitor interest. The aisles were constantly packed with passionate Italian cyclists who could not help but caress thecolorful two-wheeled creations in the booths. In general, the Italian show is better at showing off whatever is cool about our sport than other shows, and the visitors respond to it. There was even an entire hall devoted to road racing – including mass-participation Gran Fondo races. Paradigm-shattering

Building on the success of its single-pivot, light, but burly 2002 Gemini freeride models, Cannondale is adding a third Gemini model for 2003, the Gemini 900 (with Manitou Breakout, Fox Vanilla RC, Hayes HFX-9 w/8" rotor). This OnePointFive Standard-equipped bomber uses the same frame technology as last year's Gemini, but takes the entry-level price down from $2,975 last year down to $2,199.The Jekyll line, which offers adjustable full-suspension and all-mountain performance, has also been re-engineered.

It's no secret that Lance Armstrong never used Shimano's SPD-R system. He rode what he liked and those were his old Look-compatible Shimanos. After three successive Tour de France wins, the Japanese manufacturer finally decided it had enough of watching its decade old equipment bring Armstrong to the podium and set out to build a pedal Lance would approve of. It looks like the new design got the nod of approval: Armstrong has kept them on his bike since spring. The svelte 276-gram/pair (plus 60 grams for the cleats, screws and washers) pedals are the fruit of their radical redesign labor.

While we thought 2003 couldn't get any brighter for Shimano and its highly redefined XTR group, the Japanese manufacturer surprised us again this morning with the announcement that it would be producing its first XTR-level wheelset. Sources report the wheelset should go for around $850 and be available about the same time as the component group (around January, 2003.) Vital stats include: total wheelset weight of 1650 grams, both 24 spoke count in a paired lateral crossover pattern and, most significantly, are both tubeless and traditional-tire compatible. Although the wheels were not

Marin Bikes just announced the launch of its patented Quad technology which will be featured on the company's XC full suspension bikes. The Quad was developed with chief designer John Whyte, an ex-Formula One engineer and cycling enthusiast. The Quad, named for its four-bar linkage system, four inches of rear wheel travel and quadratic wheel path equation will be available in four models including the East Peak, Rift Zone, Mount Vision and Mount Vision Pro. According to Marin, the Quad suspension design is a four-bar linkage system with a patented Intelligent Pivot (i.e. similar to VPP

So why did ONCE go so fast on Wednesday? Was it because the team pedaled harder and stayed in better formation and had good equipment? Well, that is one explanation. Another is that all of the other teams only had nine riders, while they had ONCE (Spanish for “eleven”)! Sorry... I had to throw that in. Beyond the numbers, it is worth noting that the teams that go fastest have 100 percent of the riders wearing aero helmets, rather than a mixture of headgear and even of clothing and equipment. You also tend to see other riders on fast teams using their aero’ bars further back in the line,

Oscar Freire sprinted past Robbie McEwen and Erik Zabel to win stage two aboard the mount that has brought so many victories to Mapei and Rabobank. He was riding a Shimano Dura-Ace equipped Colnago C40, the 2.5-pound frame that won Paris-Roubaix five times between 1995 and 2000. But it is not just another bonded carbon frame, since Colnago’s construction methods C40 are unique and analogous to its method of constructing steel frames. Integral to the C40 are one-piece molded, hand-finished carbon lugs that eliminate the bonding problems and weight of aluminum lugs and are stronger,

Armstrong won on a special superlight prototype aero’ bar that Dedahad whipped out for him for the Tour. It is completely flat; there is nodrop to it like the Vision Tech bars the team has used in the pastand still has on some of its time trial bikes. It is made out of aluminum, but according to Deda’s Fulvio Acquati, “We are still working out the exact design with Armstrong, and when we get it exactly the way he wants it, we will make it out of carbon.” Dedaalso has a carbon aero’ bar that Acquati was showing to the teams the daybefore the prologue. The carbon base bar is just a prototype,

Russel Bollig’s path to Lance Armstrong’s feet began with Tyler Hamilton,for whom he first built some custom orthotics in 1992. About four yearsago, Christian Vande Velde got some as well. They passed the word on toArmstrong, who was looking for an improved fit in his cycling shoes, andafter the 2001 season Bollig went to Austin, Texas, to fit the three-timeTour champion. While at Armstrong’s home, Bollig used resin-filled casting socks tomake casts of Armstrong’s feet and ankles. Then, back at his Podium Footwearshop in Boulder, Colorado, he made plaster duplicates of Armstrong’s feetfrom

This year will not be the first time anyone has ridden a titanium Litespeed at the Tour. That’s happened many times since the small Tennessee-based industrial metals firm began turning out titanium bicycles in 1986.

The image of Tyler Hamilton crashing at the bottom of a key descentas the Giro d’Italia’s other main contenders is firmly emblazoned inthe minds of anyone watching OLN’s coverage and saw that loop of tape played over and over. Coming through a turn, Hamilton stood up onhis pedals and suddenly lurches forward and hits the ground. Hamilton stated in his diaryon velonews.com that the freehub had not engaged when he stood on thepedals, causing the crash. The pain he had to deal with with over the remainderof the Giro is well documented, as is the amount of time he lost on mountaintopfinishes

More solutions to mystery noises.

When Lance asks, you have to be ready to deliver. Take, for example thisstory of Armstrong’s new time trial handlebar. The day after the finish of the Midi Libre, U.S. Postal team managerJohan Bruyneel calls Deda Elementi, the team’s handlebar sponsor, to reportthat Lance is unhappy with his current equipment and wants something lighterfor the upcoming Dauphiné Libéré and the Tour. The next day, May 28, representatives from Deda drive from their factoryin Campagnola Cremasca, Italy, to Les Deux Alpes to meet with Armstrong,Bruyneel and Lance’s mechanic, Jean-Marc Vandenberge. At the

When a carbon fiber handlebar breaks, it makes a sound like a snapped twig.There’s a sharp “crack!” followed by a hollow splintering sound, just asif you’d broken a dry stick over your knee. Then, silence.The similarity in sound is due to the similarity in structure. Carbonfiber, like wood, is made of long strands of high-strength material surroundedby a resin matrix. Trees do it with cellulose and sap. Engineers do itwith synthetic polymers and glue.The difference, of course, is that carbon fiber is considerably strongerthan wood; in fact, carbon’s raw tensile strength figures typically
