Engineered with advanced materials and fully in-house manufacturing, the SL-K combines durability, innovation, and style, making it the ideal choice for both professional cyclists and passionate enthusiasts looking for the best equipment. At the heart of the SL-K Light Direct Mount lies FSA’s Hollow technology, which creates ultra-light, hollow carbon crank arms. This design offers the perfect balance of lightweight construction and exceptional stiffness, ensuring top performance and long-term durability. The sleek UD carbon finish enhances its aesthetics, making it a visually striking and technically superior choice for demanding cyclists. The revolutionary MEGATORQ technology from FSA redefines the standard for chainring performance, ensuring an unmatched combination of chain retention, smooth shifting, and durability. This innovation is the result of meticulous design and collaboration with professional athletes, tested in extreme conditions to meet the highest expectations. The advanced tooth profile design creates an optimized contact point between the chain and chainring, reducing chain drops even under maximum load. The updated derailment angle on the non-contact side further enhances shifting efficiency, allowing for faster, more precise gear changes without compromising retention strength.

After many years I wore out my derailleur gears. Since I ride on my wind trainer daily, I needed to get up and riding again. Riding us part of my cancer therapy. Replacing the gears was a quick and easy way to fix the problem. Cost was fine and the delivery was fast. Thank you.
Got this for my kids bike. He does XC racing. Has been riding in dry lose dirt, wet conditions. Lots of climbing and some downhill. He loves them. Shipped fast and in sexure packaging. I would definitely buy again.
Heard a lot of good things about this tires put them on my commuter. The roll much faster than the schwable energizers on it. Puncture protection only time will tell.
Specialized SWorks SL8 light and fast. Sierra Bike Supply was helpful and responsive. Recommended online store.

Exceptional Wheels
The CLX III are exceptional I was a little apprehensive about buying them having ridden the Enve 4.5 but you feel less crosswinds and their lighter and spin fast. The spokes seemed to offer a lot of dampening vibration. Win win in my book.
