Lezyne 11 Speed Chain Drive Breaker Tool

So, you scored a fancy new Campy 11 speed gruppo. Congratulations! But, if you try using your old chain tool on that 11 speed chain, your next ride is going to be a short one. Lezyne designed the 11 Speed Chain Drive Tool with a backing bolt designed specifically to flare your 11 speed chain pin. You'll need that. The 11 Speed Chain Drive is tough. The forged steel body is CNC machined to tight tolerances for accuracy. The body is contoured to feel comfortable in your hands. Lezyne even integrated two Mavic splined and two square spoke wrenches into the body for a little added versatility. The breaker pin and backing bolt can be replaced in the unlikely event of a break, and Lezyne even had the foresight to include a spare breaker pin just in case. The Lezyne 11 Speed Chain Drive Tool is compatible with eleven speed chains and can be used for adjustment of wheels equipped with Mavic splined or standard square spoke nipples.
