Specialties T.A. 6-Bolt Chainring: 45t x 152mm - REF 106?
This tough to find 6-pin pista chainring, to fit on a "professional" adapter. The adapters were either REF. 173 for 3 bolt crank arms, or REF. 175 for 5 bolt cranks. This is the Ref 106 model, identified by the countersunk chainring bolt holes (the 104 was identical but without countersinks).
This one somehow has zero logos and just "Made in France"
Near Mint lightly used shape. Teeth show minimal wear.
