Flat mount brake caliper
Lewis BB2 SLR Flat Mount Road Disc Brake Caliper
A 68.5g CNC-machined flat mount caliper with titanium hardware that swaps straight onto Shimano or SRAM hydraulic road systems, saving serious weight over stock calipers without giving away clamping force.
Highlights
Why we rate it
Feather-light
At 68.5g with titanium bolts (pads and fitting excluded) it is one of the lightest flat mount calipers available.
Machined from billet
CNC-cut from 7075-T6 bar, with a thickened inner wall for strength under hard, repeated braking.
Works with your levers
Choose a mineral-oil seal set for Shimano or a DOT version for SRAM; generous piston clearance helps pairing with most levers.
Front or rear
Front and rear calipers are identical, so one part number covers either end.
Five finishes
Black, silver, gold, purple and a multi-tone Nebula finish.

Sachet Instructions
1. Grab your empty old bottle of Muc-Off. (You may need a pair of adjustable pliers to remove the trigger from the bottle). Or purchase our Bottle for Life.
2. Fill up to the shoulders of the bottle with 1 litre of lukewarm water for faster formula activation!
3. Carefully cut one corner of the sachet open along the diagonal cut lines.
4. You can carefully pour the sachet straight into the top of the bottle. Or using the box, fold the inside of the lid together using the printed lines as a guide and use this as a funnel to pour the powder into your bottle. (Please see our video for full instructions on this.
5. Screw your spray trigger back onto the top of the bottle. Ensure it’s tight!
6. Shake the bottle vigorously for 30-60 seconds to activate the formula. If you notice any undissolved powder simply keep shakin’ it!
7. Go clean that filthy bike!
