My Transcontinental Build
I designed this build to tackle the Transcontinental No.4, a race with an expected total of 50,000 metres of climbing and 4,000 km’s distance. With this in mind this bike aims to be light and but more importantly comfortable. A super compact frame keeps weight down while also increasing seatpost flex and drive-train stiffness while thru-axles front and rear keep the handling positive. To increase rear compliance I custom shaped skinny stays by flatting them laterally near the dropouts. I also lowered where the stays meet the seat tube to encourage that seatpost to flex a little bit more. The design takes advantage of many of the new standards that have been developed recently. An oversized T47 BB shell gives great stiffness to the cranks while guaranteeing none of the creak associated with PF30 BB. Flat mount brakes front and rear do away with adaptors with their direct mounting system while also keeping the weight down. Schwalbe's road tubeless system gives the traction and ride quality of tubular with the convenience of clinchers and better puncture protection. Finally the SRAM wireless eTap system brings the advantages of electronic shifting in a package that requires no cables, a good send for frame builders like me! All in all this is a thoroughly modern steel beast!
