The 2023 Cruzbike Q45 complete build comes stock with
Rever MC-X mechanical disc brake calipers.
These are flat-mount mechanical calipers that feature a dual-piston design (meaning both brake pads move simultaneously to clamp down on the rotor, rather than a single moving pad pushing the rotor against a fixed pad).
Pad Compatibility
The Rever MC-X mechanical disc brake calipers use a very common standard for their pads. They are fully compatible with
Shimano K-Type (K02S, K03S, K04S, K05S) disc brake pad shapes.
When shopping for replacements, look for pads listed as compatible with:
- Shimano K-Series (such as Shimano Dura-Ace, Ultegra, 105, or GRX flat-mount brakes).
- RideRever MCX / MCX-2 / Attack flat-mount series.
Note: Ensure you choose the
smooth, non-finned variants. Pads with integrated cooling fins will not clear the caliper body properly.
How to Change the Pads
Because the Rever MC-X is a dual-piston mechanical brake, changing the pads is very similar to changing them on a standard Shimano hydraulic road caliper, but with mechanical cable considerations.
The process is clearly explained in the
TRP Disc Brake Pad Replacement Video on YouTube, which follows the exact same pin-and-pad layout.
Step-by-Step Overview:
- Remove the Wheel: Release your axle and pull the wheel out to give yourself clear access to the bottom of the caliper.
- Back Off the Pad Adjusters: Before removing anything, look for the pad adjustment screws on both the inner and outer sides of the caliper body. Use an Allen key to back them all the way out. This resets the dual pistons to their widest position to fit the brand-new, thicker pads.
- Remove the Safety Clip & Retaining Pin: Locate the small safety split-pin or clip on the backside of the caliper holding the main pad pin in place. Pull it off with needle-nosed pliers. Next, unscrew or pull out the threaded pad retaining pin.
- Slide the Old Pads Out: Pull the old pads and the metal sandwich spring out from the bottom or top slot of the caliper.
- Install the New Pads: Place the new pads onto the new metal sandwich spring (making sure the friction sides face inward toward each other). Squeeze them together and slide them back into the caliper.
- Secure and Adjust: Reinstall the retaining pin and safety clip. Re-insert your wheel, and slowly dial the pad adjusters back in until the pads are close to the rotor without rubbing.
