carbon

A look at some of the concerns surrounding new and repurposed carbon fiber materials in the production of bikes and bike parts.

The integrated bar-stem combo and seatpost can help save weight, and also reduce road vibrations, adding comfort, but not mass.

The North American Handmade Bicycle Show (NAHBS) has been postponed until August 21 - 23, but you can still get a look at some of the featured bikes this week on VeloNews.com.

If moderate heat doesn't pose a problem for carbon fiber, how about cold and big temperature fluctuations?

A reader asks whether the heat of a closed car or exposure to direct sunlight can damage a carbon frame.

A cracked or broken carbon frame can be fixed. Lennard Zinn checks in with Craig Calfee's repair shop.

Dear Readers,
I’m in the Denver airport about to fly to Italy for the Giro d’Italia. I have enjoyed a lot of the feedback from a few recent columns, and I thought you might as well. Next time you hear from me will be from the Giro, so look for some cool bikes for the team time trial soon.

Dear Lennard,
In your Earth Day column there was a question about a cracked carbon frame. Since it is a save the earth day of posting I thought I would ask about the possibility of repairing a cracked carbon frame (small crack obviously). Since you can buy epoxy and carbon, would it be possible to repair a carbon frame? It would be ugly but would it be rideable?
Scott Dear Scott,

Should I wax my carbon seatpost?

Questions about inspecting carbon forks for safety, trying Wippermann chains with Campy 10-speed systems and using Shimano MTB derailleurs with 10-speed road systems. What to do? I'm low on funds and that's the main reason I haven't replaced them as yet. I will add there are no stress fractures or noticeable wear.

Can I use the same brake pads on my aluminum and carbon rims?

TorqueDear Lennard,I recently purchased my first full carbon bike, absolutely love it. Yet, I'm scared of over-torquing the seatpost clamp. Is there a torque wrench you could recommend that works on Allen wrenches? What's the worst that happens, the seatpost clamp needs replacing or I have this fear of the actual seat tube deforming, I'm not doing the Samsonite luggage monkey torque on it, but "hand tighten" is just too open to quantify.ThomasDear Thomas,First of all, carbon frames generally have a separate band clamp to tighten the seatpost, and, yes, the worst that can happen,

More tire talkDear Lennard,I really enjoyed your recent wet-road tire discussion with Tom Petrie and Alberto De Gioannini. Just the topic I was looking for, but I'm still a little confused. I thought the cord compound made a big difference and it wasn't mentioned at all. I recall racing in the rain in a crit next to a friend who was running cotton-cord sew up tires as opposed to my silks. While we'd been comparable in bike handling otherwise, I found myself nearly sideways in corners while hewent around like on a rail. We'd pumped our tires to comparable pressures.I'm taking a group over for
