The Ti Parts Workshop Chainring Bolts are suitable for the Brompton Spider crank, which has the replaceable chainring fitted to all new Brompton bikes since 2013.

These bolts that come stock with your Brompton can round off and rust over time and are worth replacing if needed with these more lightweight and rust-proof titanium bolts. Supplied in packs of five, this set includes five inner bolts and five outer bolts which use a 5mm Allen key for installation.
