Details
These chainrings work with Middleburn X-type (external bearing) cranks only. They will fit on other Middleburn cranks but the chainline will be incorrect.
All chainrings feature our Drop-Stop tooth design and are made from 7075 Aluminum.
Use a 10 or 11 speed chain. If using a 9 speed drivetrain, plan to use a 10 speed chain (it will shift fine), as the 9 speed chain fits too loosely on the ring.
Product weights: 28t - 61g, 30t - 65g, 32t - 70g
Color: Black
Chainline is 50mm on all rings.
