Description
Will this work?
- Campagnolo Gran Sport rear derailleur
- Chromed steel, short cage
- Ball bearing pulleys, early type
- Standard threaded hanger mount
- 5-speed era, fits Eroica builds
- Includes: derailleur only
Condition: Excellent condition. Chrome is bright on body and cage. Stampings are crisp. Pivots move freely, ball bearing pulleys spin smoothly. Lots of miles left.
Workshop Wisdom: These early Gran Sport pulleys run on actual ball bearings — visible right at the pulley face — a feature that vanished from stock derailleurs decades ago and only returned on premium aftermarket pulleys. Flush, regrease, and they’ll outlast anything sealed.
Notes from MyBikeThing — add after the first sentence:
Workshop Wisdom: Gran Sport pulleys run on plain bushings, not bearings — a drop of oil at each pulley bolt and a wipe of the parallelogram pivots is all the service they ever need. Don’t overtighten the pulley bolts; they set the spin.
Guarantee: You put in the miles, we put in the work! 30 day Guarantee, rest assured of fit, function and condition 🙂
