Description

The Fit Tri is a straightforward aftermarket sprocket that keeps the classic Fit look. It is CNC machined from 6061 T-6 aluminium with extra material around the drive bore, which is where a sprocket takes the most load.

It uses a 19mm centre bore, so it suits Fit complete bikes running stock cranks and anything else on a 19mm spindle. It will not work with 22mm or 24mm cranks. The 25 tooth size weighs 73g and runs 1/8 inch teeth.

Features

Made for 19mm cranks. The 19mm centre bore suits stock cranks on Fit completes, but it will not fit 22mm or 24mm spindles.
Extra material at the bore. Fit added material around the drive bore, the spot that takes the most load, to keep the sprocket strong.
CNC machined 6061 T-6. Cut from 6061 T-6 aluminium, so it stays light without giving up strength.
Runs 1/8 inch teeth. The 1/8 inch teeth suit a standard BMX chain, so nothing else needs changing.
25 tooth at 73g. The 25 tooth size weighs 73g, a common gearing choice for street and park.
