Along with the Shimano Dura-Ace 9200 Di2 group on the size, Truthful Wheel Bikes additionally had one thing else to share with us this week. Particularly, a 12-speed highway drivetrain with parts from 4 totally different producers. The result’s a really gentle Open Up with an attention-grabbing mixture of drivetrains.
Why would you wish to mix these totally different teams fairly than deciding on one full drivetrain? Based on Truthful Wheel Bikes, it was all about that gearing.
“We simply completed an Open UP gravel bike which by itself is good however what makes this one particular is that we blended Dura-Ace 12 velocity and SRAM XPLR/Crimson stuff to get a very good gravel gearing. We additionally examined totally different cranks and rings with the Dura-Ace stuff to see what labored and what didn’t. Ended up with a 48/33t [chainring] and 10/36t [cassette] for gearing, which in my thoughts is fairly ultimate for gravel.”
The drivetrain is made up of Shimano Dura-Ace 9200 shifters and derailleurs, a SRAM Drive XPLR 10-36t cassette with RED Flattop chain, and a Lightning carbon highway crank with 48/33t Carbon-ti chainrings. Truthful Wheel claims to have examined the system sufficient to confirm that the shifting works properly whereas offering a 48-10t excessive gear, and 33-36t low gear for additional assist up the steep bits.
Whereas the brake calipers are the usual Shimano 9200, they clamp down on Carbon-Ti 160/140mm rotors mounted to Carbon-Ti Centerlock hubs.
The construct could function a few of the lightest elements on the market, however that hasn’t stopped Truthful Wheel from together with the Cane Creek eeSilk+ carbon suspension seatpost. Extra cockpit parts embody an Mcfk carbon stem, FSA Ok-Wing AGX carbon handlebar, and a Specialised S-Works Phenom Saddle.
The construct is completed off with Truthful Wheel’s personal V2 Carbon water bottle cages and tubeless valves. The cages weigh in at 22g every, and can be found in 3k weave or UD carbon finishes, each in matte or gloss end for $35 every.
The valves are provided in 48 or 60mm lengths, and in six colours. They appear to be pretty fundamental aluminum our bodies with a brass valve core, however they’re additionally attractively priced at $7.50 for every valve and weigh simply 4.6 or 5.1g respectively.
