Does 53 x 14 drivetrain ratio sounds gnarly? Yeah. Might sound crazy if you use them on the streets but on the track, might help you a lot. Evelyn Stevens will be attempting to carve her name on top of the women’s UCI Hour Record, currently at 46.882km this Saturday.
Instead of a pursuit-style track bike, the frameset is a Specialized S-Works Shiv TT that has been prepped for the track. The derailleur hangers and bottle-cage bosses were removed for aerodynamics, and spacers were added to the Zipp track disc’s hub to bridge the gap to the 130mm road frame spacing. Stevens also has a team-only custom stem to get her position low, with a 12cm drop from the top of her saddle to the top of the arm rest pads.
53×14 for an hour. How far will Stevens go? Check out her ride below. Photos by Ben Delaney / Immediate Media for BikeRadar.
