KOM Cycling Indoor Trainer Block Black, One Size

"What Our Gearhead® Experts Are Saying:""I’ve used a lot of riser blocks over the years, and this one feels noticeably more stable. The three height options make it easy to level out different trainers, and the grippy base keeps it from sliding when I’m sprinting out of the saddle. It’s a simple upgrade that makes long indoor sessions more comfortable.""When the weather turns or the training plan calls for focused intervals, we head to the pain cave and settle into steady miles. The Indoor Trainer Block from KOM Cycling keeps our front wheel planted and our bike properly leveled, so we can focus on power, cadence, and breathing instead of balance. Designed to accommodate tire sizes from 700c road setups up to 29er mountain builds, this block offers three height positions to match a wide range of trainers and bike geometries. The webbed grip bottom prevents slipping on smooth floors, even during out-of-the-saddle sprints and high-watt efforts. A wide, stable cradle supports the front tire securely, helping reduce unwanted movement and creating a more natural riding position. Whether we’re logging base miles or chasing virtual climbs, this block keeps our setup steady and aligned for productive indoor training."
