Heel contact with the crank arm or chainstay is more than an annoyance—it forces compensation in your pedal stroke and can create knee tracking issues over long rides. Riders with wider hips, larger quads, or a naturally splay-footed pedaling style often can't achieve adequate clearance with standard Q-factor pedals. The Wahoo Speedplay Zero Extended Spindle pedals address this with 56mm, 59mm, and 65mm Q-factor options beyond the standard 53mm. That 12mm range of additional stance width covers most clearance issues and opens up fitting options that other pedal systems don't provide.

Bike fitters frequently specify extended spindles when standard Q-factor pedals can't accommodate a rider's biomechanics. The wider stance moves your foot outboard, creating clearance between your heel and the drivetrain while also affecting knee tracking angles. For riders whose knees naturally track wide, a wider Q-factor reduces the inward stress that accumulates over thousands of pedal strokes. The three extended options let you dial in exactly the stance width your fit requires rather than forcing a compromise.

Except for the longer spindles, these pedals are identical to the standard Speedplay Zero. The stainless steel spindle handles structural duties while a Grivory composite body keeps weight at 222 grams per pair—the same weight across all spindle lengths. Triple sealed cartridge bearings paired with needle bearings manage the rotation with minimal maintenance. There's no rider weight restriction, so heavier cyclists can run the extended spindles without concerns about spindle limits.... Read More
