Three-time Canadian cyclocross national champion Wendy Simms made the trek south for her first run at the Single Speed Cyclocross World Championships this past weekend in Seattle, Washington. With skies opening up for the previous 24-hours the course was a quagmire of inch deep mud. Simms donned a figure skating costume and dominated the womens race. With the day won, Peloton was able to grab Simmss World Championship Ridley X-Night for a closer look.
The Ridley X-Night uses a full carbon frameset that features a BB30 bottom bracket and internal 1.5 oversized lower head tube bearing and fork crown. For muddy conditions the X-night uses Ridleys mudless tube shapes on the seat stays and fork to more easily shed mud and resist buildup. Ridley rounds out the X-Night with an integrated seatmast, internal Kevlar cable guides and replaceable CNC rear dropouts.
With the Single Speed Cyclocross World Championships a one off event, Simmss single speed was actually a spare bike stripped of derailleur cables and a cassette. This gave the bike the unique appearance of a high-end race machine mixed with a bit of homegrown engineering and backyard tinkering.
Simmss championship bike was outfitted with an FSA 172.5-millimeter SL-K carbon crankset mated to a 44-tooth outer ring and locked out 38-tooth inner ring. The FSA front derailleur was repositioned with the limit screws locked down to make it into a chain guide for the outer ring. A pair of Crankbrothers Egg Beater Ti pedals deliver power to the cranks.
The rear sprocket is little more than a single cog pulled from a standard cassette. The cog is held in place on the standard cassette body with an assortment of mismatched cassette spacers. The Dura Ace rear derailleur is used as a chain tensioner with the shift cable removed and limit screws adjusted to maintain chain alignment. The front chainring and rear cog are connected via a Connex 10-speed chain. For wheels Simms was running FSA 488 tubeless carbon wheels wrapped in 32-millimeter Dugast Rhino tires.
FSA provides the stem and handlebars on Simmss Ridley X-Night. Simms uses a 100-millimeter OS-99 stem mated to a K-Force Light carbon handlebar. The Dura Ace shift/brake levers are reminders that the bike is meant for gears. A BBB bell serves as the only warning to fellow riders that they are about to be passed.
A WTB Shadow V SLT saddle completes the cockpit on Simmss Ridley. The titanium railed saddle is mounted via an external aluminum seat clamp to the X-Nights integrated seatmast. The integrated seatmast is designed to reduce overall weight, but also adds stiffness to the frame.
