Pro Bike Check: Steve Smith’s Blackboxed, Elongated Devinci Troy 650B Mountain Bike
After Sick Mick put up a rather quick time at the Fox Air DH on his own prototype bike, pole positionee Steve Smith had to really bring it. And bring it he did…aboard a modified version of the all-new Devinci Troy 650b trail bike.
The stock Troy gets either a 140mm or 150mm fork depending on spec, mated to a 140mm travel Split Pivot rear end. Smith was running a 160mm Rockshox Pike for the race and had a smattering of Blackbox SRAM drivetrain bits throughout. Check the full build after the break…
Like we saw on their bikes at Sea Otter, the team gravity riders run their piggyback shocks inverted to lower the center of gravity a bit.
Smith’s nickname is the Canadian Chainsaw Massacre, so Devinci used their occasionally vowelless graphical scheme to customize the frame a bit.
The suspension’s set in the lower, slacker setting.
Avid X0 Trail brakes keep things on the edge of control.
The most interesting part of the drivetrain was the modified X-Dome cassette, which could be based on the 11-speed XX1 cassette since it’s being turned by an XX1 chain. There are only seven speeds, spanning from 11t to 24t.
Having the 11t cog means the cassette needs to sit all the way to the outside of the freehub body, so there’s a taller ring inside the largest cog to prevent the chain from falling off and into the spokes.
Shifting’s handled by an X01 rear derailleur with modified super-short cage. It still has the offset upper pulley to work with the X-Horizon derailleur’s movement pattern.
Up front, he’s running a 36-tooth standard 10-speed chainring and X0 crankset. Crankbrothers Mallet DH pedals and e*thirteen chainguide round it out.
The shifters were modified to work with the smaller cassette. Note the “11” on the front of the shifter pod was blacked out a bit with a Sharpie marker. Custom lockrings on the grips continue the Chainsaw Massacre theme.
Cockpit includes a Truvativ Holzfeller stem and Boobar (I think) handlebar. He’s got a carbon fiber backplate for his race number, which makes for a very flat, clean number plate that shouldn’t rattle or flap.
An SDG Fly saddle is clamped to a standard seatpost, not a dropper.
The wheels are the new Easton Havoc 650B wheels we spotted earlier.
