Shimano 105 FC-5500 Crank Arms | 172.5mm | Octalink V1 | 130 BCD + Bolts

Description

Will this work?

• Shimano 105 FC-5500, 9-speed double road crankset arms
• 172.5mm arm length
• Octalink V1 spline interface — requires Octalink V1 compatible BB (e.g. BB-6500, BB-ES25/50)
• 130 BCD double chainring pattern
• Compatible with 5-arm double chainring sets at 130 BCD
• Includes chainring bolts — no chainrings

Condition: Noticeable scuffing on the arms consistent with use. Yellow 105 logos intact and well preserved. Threads clean on both arms. Mechanically sound.

Notes from MyBikeThing: The FC-5500 is the vintage sweet spot of 9-speed Shimano 105 — Made in Japan, Octalink era, and built to last. Arms-only is exactly what you need if you’re swapping rings or rebuilding a period-correct drivetrain. Chainring bolts included so you’re not hunting for hardware.

Workshop Wisdom: Octalink V1 and V2 splines are not interchangeable — V1 uses a shallower, wider spline than V2. Confirm your BB spindle spec before ordering. The BB-ES25/BB-6500 are the common V1-compatible units still findable on the used market.

Guarantee: You put in the miles, we put in the work! 30-day Guarantee, rest assured of fit, function and condition. 🙂
