Our premium 1X RaceFace Boost 148 direct mount Oval chainrings are designed for CINCH system RaceFace uses to mount chainring directly to the crank. This version is for BOOST 148 specific bikes only.

Difference between Boost148 and non-boost chainrings is in the offset/dish of the chainring itself only. You would use same crank in both boost and non-boost bikes, but chainring offset has to be different to accommodate chainstay clearance. Boost chainrings have only 3mm offset while non-boost ones 6mm.

Advantages of our special Direct mount chainrings:

- Finest design to provide excellent weight to strength ratio
- One of a kind special oval shape (Patent Pending)
- Unique Patent Pending narrow-wide teeth profiles to keep your chain in place for minimum 12 months!
- They save weight because they don't need the spider and chainring bolts.
- The ability of installation of a smaller ring sizes that can't be mounted on regular spider.
- Superb quality and great look.
- You will ride faster using ovals. If you keep using round ring then others will get quicker.
- You will not "feel" the oval shape at all
- Reduces stress on knees
