Gebhardt Chainrings
Gebhardt rings are machined from Dural aluminium. Good, stiff, wear-resistant rings. Available in both 130mm and 144mm PCD. For use with 1/8" chains.
Dural aluminium is exactly the same stuff that considerably more expensive rings are made from. We tend to have a mixture of these in stock - check the options to see what's currently available!
130mm chainrings are compatible with the Sugino RD2s. 144mm rings fit the Sugino SG75.
