SunXCD 3 arm Chain Rings

These are brand new chain rings just introduced by SunXCD for their 50.4mm BCD cranks, but they fit Stronglight 49D, TA Cyclotouriste and Velo Orange 50.4mm cranks as well.

The outer rings attach to the following crank arms:

• T.A. Cyclotouriste (Pro Vis 5)
• Suntour SunXCD crank arms
• Stronglight 49D
• Velo Orange 50.4 crank sets

The inner rings attach ONLY to the SunXCD outer rings and you will need the bolt set to attach the inner and outer rings together. See other listings on our eBay shop.

So if you have another make of rings, you will need both inner and outer SunXCD rings, plus the bolt set.

Specification

The rings are ramped and pinned and 6,7,8,9,10 speed compatible. The material is 7075 alloy. To improve shifting and give superior finish, all the chainrings are CNC'd twice, once to create basic shape, including groove for quicker shifting, and the next, they take chamfering process to make them look vintage in style.
