No, once correctly positioned and torqued down, this SC-03 model sits just clear of the chain's normal path and only makes contact if the chain actually starts to drop toward the frame, so it does not interfere with everyday shifting between chainrings. It works purely as a passive backstop rather than a moving part in the drivetrain, so there is nothing to adjust or maintain once it's installed correctly.

It mounts using the aluminium adapter block at your front derailleur's mounting bolt, secured with a 4mm hex key at the derailleur screw and a 2.5mm hex key for the adapter block itself. Once fitted, position it so it sits close to but not touching the inner face of the chain when in the smallest chainring, then torque both bolts down and do a full range of test shifts through all chainrings to confirm there's no rubbing before riding.

This design mounts to a braze-on or clamp-style front derailleur post using the included adapter block, which covers the vast majority of road and gravel double-chainring setups. It is built specifically for double-chainring drivetrains with a front derailleur, so it is not intended for 1x (single-chainring) setups that have no front derailleur to mount to.

At roughly 105mm long and 9.5mm wide, this CNC-turned aluminium alloy piece is minimal in both size and weight, adding a negligible amount to the bike compared to the peace of mind and mechanical protection it provides. Riders chasing every gram sometimes skip a chain catcher, but for most, the trade-off strongly favours keeping the chain contained.

Yes, this is a genuine, quality-checked LEBYCLE SC-03 chain catcher, CNC-turned and anodised for durability. Dispatch typically takes up to 3 working days from order confirmation, and total delivery time after that depends on your location and pin code, so we cannot promise an exact day count upfront. All orders are prepaid at checkout since cash on delivery is not offered, and every order carries DoGoodCo's assurance of a genuine, correctly specified part.
