Replaceable Aluminum Derailleur Hanger for all modern Ibis bikes. It's a good idea to carry a spare.
Includes 12mm fixing bolt for boost models and Hakka MX. Older 142 models use a 6mm fixing bolt sold separately.
The hanger designed for the Boost spacing bikes will fit all previous 142 models(Ripley, HDR & SLR). It does not require the backing nut of the two-piece fixing bolt assembly as the new hanger has threads built in for the standard chainring bolt used.
