Cadenas de bicicletas

Chains are one of the most frequently replaced components on a bike, and one of the few where the quality gap between options is measurable. A well-chosen chain shifts more cleanly, runs quieter, and lasts significantly longer than a baseline option. A factory wax-treated chain from CeramicSpeed can save meaningful watts over a standard wet-lubed chain in independently tested conditions — free speed that requires no added effort. RA Cycles carries 142 chains and chain drivetrain components spanning 8 through 12-speed road and MTB compatibility, plus 1/8" track chains for fixed-gear and velodrome setups.

Brands include CeramicSpeed UFO factory-optimized chains, KMC, SRAM (including the XX SL Eagle T-Type for 12-speed MTB), Shimano, Campagnolo, YBN titanium track chains, and Ethirteen chain guide components for full-suspension mountain bikes. Whether replacing a worn chain before it damages your cassette, building up a road drivetrain, or speccing a track bike, the range covers every speed standard in current use.

Bike Chains — How to Choose

Chain selection starts with speed compatibility — the number of sprockets on your cassette. Chains are width-matched to their intended speed: 12-speed chains are narrower than 11-speed, which are narrower than 10-speed, and so on down to the wide 1/8" chains used on track and single-speed setups. Cross-compatibility exists in some cases, but matching chain to drivetrain specification is the safest approach. Wear is the issue most riders underestimate: when a chain stretches beyond roughly 0.75% of standard pitch length, cassette wear accelerates sharply. A chain wear gauge takes seconds to use — replacing on time extends cassette life by several chain cycles.

CeramicSpeed UFO chains arrive pre-treated with their wax lubricant system and optimized for minimum friction. Third-party testing has measured 2 to 5 watt savings compared to standard wet-lubed chains at race pace — meaningful free speed without added effort. YBN titanium track chains deliver weight savings without compromising the durability required for velodrome use. SRAM XX SL Eagle T-Type chains are built specifically for their 12-speed T-Type drivetrain system, with a flattop link design that improves mud shedding and chain retention under load.
