Mountain bikers with Shimano Hollowtech II cranks who want an easier to adjust, better looking preload cap.
The Burgtec Shimano Crank Bolt replaces the standard preload cap on Shimano Hollowtech II cranks. Instead of the special plastic tool, it takes an 8 mm hex key, the same one most riders already carry.
It's machined alloy with an anodised Toxic Barbie Pink finish, so it's an easy way to add a bit of colour to your cranks or match other Burgtec parts.
Remember it's a preload cap, not a crank bolt that holds the arm on. It only needs 0.7 to 1.5 Nm, just enough to take the play out of the bearings before you tighten the pinch bolts.

Setting preload
Loosen both pinch bolts on the left arm, snug the cap to 0.7 to 1.5 Nm until the play is gone and the cranks still spin freely, then tighten the pinch bolts evenly. Don't crank on the cap, it can damage the thread and bearings.
