The new Specialized Crux could be described a few ways: An Aethos with 47mm tire clearance. An ultralight gravel bike. And, notably, a cyclocross bike.
On the heels of its ultralight, 585g Aethos road frame, Specialized today announced the new 725g Specialized S-Works Crux, a frame that builds up into a sub-16-pound gravel bike. There are also Pro, Expert, and Comp models available built with an 825g frame, with prices ranging from $3,200 for a frameset up to $12,000 for the complete S-Works bike.
Specialized is keeping the Diverge gravel bike, with its integrated storage, mounts aplenty, and FutureShock front suspension. The new Crux, by contrast, is the ultra-minimalist take on gravel with just the standard two bottle-mounts on the main frame (and one under the down tube), round tubes, and no suspension beyond the Pathfinder Pro tires and a bit of flex in the Roval Terra seatpost.
Gravel or cyclocross or both?
Interestingly, when gravel bikes first made a push into the broader cycling consciousness, a common question was, ‘well, isn’t this just a cyclocross bike?’ And the answer by those making gravel bikes was, ‘no, this is completely different.’ And, for sure, gravel bikes typically have lower bottom brackets, slacker front ends, more tire clearance, more mounts, and, increasingly, storage options of some sort.
The Crux was long Specialized’s cyclocross platform — and it still is. This new bike has geometry that sits between aggressive gravel and traditional cyclocross, but with gravel-tire clearance.
Whereas the Diverge hunkers down with 85mm of bottom bracket drop, and the outgoing Crux stood taller at 69mm, this new Crux has a 72mm drop.
The top tube is a bit longer, per the current progressive geo trend. So a 56cm frame, for example, has a 56.8mm effective top tube. The head tube angle is 72 degrees on a 56cm frame.
With a trail figure of 64mm in a 56cm, its handling is definitely on the quicker end.
So why the merge of two styles? Trek and Cannondale also recently launched new gravel bikes. Cannondale has positioned its SuperSix EVO SE similarly to the Crux — a gravel and a cyclocross bike. Trek rolled out a fleet of new decidedly gravel Checkpoint models — and then one single new Boone ’cross model. In all cases, it’s economics: gravel is booming while ’cross is not.
