The Answer Slider Euro Bottom Bracket Kit allows a racer to easily and externally adjust chain alignment and crank position without having to remove crank arms in the process. The Slider BB Kit includes two CNC machined aluminum cups with precision sealed bearings, two adjustable locking collars, a titanium square tapered spindle (JIS style) and two spindle bolts.

Light weight and strong, install it on your young racer's rig and as long as they stay on the same frame, you can change out Answer crank arms as they grow without having to change the whole set up. Saving you money and giving you the opportunity to really dial in the race bike. Incorrect crank length is one of the most common set up issues we see in the race world and Answer has a total solution for you with their crank/bottom bracket combos.
