Product Description
Replacement middle / inner ring from the legendary Stronglight 63 and later 93 cranks. This is an earlier ring, identified by the pointy teeth vs the later more rounded teeth.
The rare Stronglight model 63 SC (Super Competition) was introduced in 1963 as an update to the 57 SC, their top of the line racing model. It's arm profile and double taper is similar to the 49D, but the SC line uses a star shaped 122mm integrated spider. It's main updates are the use of standard allen chainring bolts vs the 10mm traditional hex bolts on the 57, and the arm edges are a bit less rounded than on the 57. They were produced until 1968, when the 93 SC took over the racing model.
Condition
Either just barely used or a new old stock take off. Some light cosmetic wear but no visible tooth wear.
