Shimano Deore XT M8100 Overhaul Kit (32T)
Every Deore XT M8100 wear part in one bundle
SKU code: SHM-M8100-OVERHAUL
Sold Out
Every wear part on a Shimano Deore XT M8100 12-speed mountain bike drivetrain, in one box. When the cassette, chain, chainring, rotors, pads are due at the same time, this kit replaces the lot in one go rather than piecing the order together part by part.
Highlights
- A complete drivetrain refresh: Deore XT CS-M8100 cassette, 12-speed and the Shimano Deore XT SM-CRM85 direct-mount chainring, 32T
- Braking sorted at the same time: Shimano Deore XT RT-MT800 Ice-Tech Freeza Centre Lock disc rotor, 180 mm (external-serration lockring) (two) and two pairs of finned resin pads
- Genuine Shimano parts throughout, matched to the Deore XT M8100 series
- Sold as one fixed bundle at a single kit price
Kit includes
- 1 × Shimano Deore XT CS-M8100 cassette, 12-speed, 10-51T
- 1 × Shimano CN-M8100 12-speed chain, 126 links, with Quick Link
- 1 × Shimano Deore XT SM-CRM85 direct-mount chainring, 32T
- 2 × Shimano Deore XT RT-MT800 Ice-Tech Freeza Centre Lock disc rotor, 180 mm (external-serration lockring)
- 2 × Shimano N03A-RF resin disc brake pads with cooling fin (two pairs, 4-piston, front and rear)
Why replace them together
A worn chain wears the cassette and chainring with it, so a new chain on old cogs skips and a new cassette on an old chain wears out early. Replacing them together is how Shimano intends the drivetrain to be serviced, and it keeps the shifting as sharp as the day the groupset was fitted. The rotors and pads follow the same logic: a fresh pad on a worn rotor beds in badly, and worn rotors are the usual cause of noise and fade on long descents.
Compatibility and fit
This kit is specified for a Shimano Deore XT M8100 / M8120 12-speed drivetrain with a direct-mount FC-M8100 or FC-M8120 crank and 4-piston BR-M8120 brakes on Centre Lock hubs. The rotor pair suits a 180 mm front / 180 mm rear setup, both with external-serration lockrings (fitted with a bottom-bracket tool). The two pairs of N03A-RF pads fit the 4-piston BR-M8120 caliper; if your bike runs the 2-piston BR-M8100 it takes G-type pads instead. The kit contents are fixed, so if your bike runs different sizes or a different combination, get in touch before ordering and we will quote the right parts.
Every part in this kit is a genuine Shimano component and is covered by Shimano's manufacturer warranty against defects in materials and workmanship (two years from the date of purchase; spare parts such as pads and chainrings: Shimano's spare-parts warranty). Normal wear and tear, and damage from crashes, misuse or incorrect installation, are not covered. For any warranty claim, return the item to Tune Cycles and our team will manage the process with Shimano on your behalf.
