Ray “Derby” Scruggs, the owner/designer/manager of Derby Rims was on the scene at Sea Otter showing off two new carbon fiber road rims. Both build upon the cyclocross/gravel 23i rims that Derby debuted last year. With these rims, Derby now offers a full complement of carbon rims for mountain, road, and just about everything in between.
The RC 22i is designed for rim brake bikes and has a 22mm internal rim width (29mm outer width). The 32mm deep section provides a semi-aero profile.
The RD 22i disc rim is also new, using the same profile as the RC 22i but without a braking surface.
Weight for both models is claimed to be 440 grams each, plus or minus 10 grams. Rims retail for $430 each and include a 12mm wide Stan’s rim tape and Derby rim stickers. As a comparison, ENVE’s slightly deeper 38mm deep 3.4 front rim weighs 390 grams, but sells for close to $1,000 each. Chinese options also exist that may save both weight and money, but there is a peace of mind that comes with dealing with an American company that backs the product.
Both the RC 22i and RD 22i use a hooked bead, making them compatible with tubed clincher tires and tubeless ready tires. Scruggs explained that the rim bed cross section is a modified UST profile but still features a bead seat retention ridge in the rim’s channel. This provides secure tire retention even at the higher pressures of road. Scruggs recommends the new road rims for pressures ranging from 45 to 120 psi, mentioning in the process that the new rims are also great for gravel use. If lower pressures are needed, it’s better to get a set of Derby’s hookless bead cyclocross/gravel rim, the 23i.
The RC 22i is offered in 20, 24, 28, and 32 hole. The RD 22i is available in 24 and 28 hole. All are available now via www.derbyrims.com.
