Description

These premium 1X Sram Direct mount BOOST148 compatible Oval chainrings are designed for GXP® and Long BB30 spindle cranks. Chainring is dedicated for Boost148 bikes ONLY. Converts a regular Sram crank into a Boost specific setup.

This oval chainring with special 3mm offset converts any Sram crank into Boost148 specific setup needed in Boost equipped bikes. Boost and non-Boost Sram cranks are identical. All the offset is achieved by the chainring itself, so you can use any Sram crank for this conversion. Our regular GXP OVAL chainrings have 6mm offset whether this one has 3mm, but both chainrings look very similar.

Oval (elliptical) chainring does not compromise the work of clutch mechanism in rear derailleur(video at the bottom). These chainrings also help you to recover after knee injuries as pedaling becomes smoother and less exhausting. It is the most advanced oval chainring currently on the market.

The most advanced, Patent Pending alternate wide and narrow teeth profile currently produced, guarantee minimum 12 months of excellent chain retention capabilities! We mean it. Always use a new chain with a new chainring.
