Trek launches racy version of Domane SLR Disc

Short head tube, double IsoSpeed endurance bike launched with Degenkolb paint scheme

Last April, Trek doubled down on its IsoSpeed Decoupler concept, launching the Domane SLR with pivoting tubes front and rear. This spring, Trek is rolling out a version of the bike that has both disc brakes and a low, pro geometry; previously it was one or the other.


Trek is launching the Domane SLR Race Shop Limited Disc with a John Degenkolb Café Racer paint scheme, available through its Project One online custom order shop. 

German pro, Degenkolb, a former winner of Paris-Roubaix, is racing this year for Trek-Segfredo. Trek graphic designer Micah Moran designed the special edition paint job based on Degenkolb’s personal cafe racer moto. 

Until today, you could get the Domane SLR with discs or a short head tube — but not both

Trek has two road bike geometries. The original Domane SLR was launched in Trek’s ‘Pro Endurance’ geometry with rim brakes, which is what the teams have been racing. The Domane SLR Disc came in Endurance geometry, which has a taller head tube and shorter reach. 

The new Domane SLR Race Shop Limited Disc has clearance for 32mm tires and the same adjustable rear IsoSpeed Decoupler and integrated front IsoSpeed Decoupler as on the current Domane SLRs.

The IsoSpeed concept works by allowing tubes to flex for comfort while still being braced laterally. At the rear, this means the seat tube and the seatmast can bow within the fixed bracing of the top tube and seatstays. At the front of the bike, the steerer tube can bow a small amount within the head tube.
