We are closing the De Anza location and are moving to Santa Clara. The remaining inventory will be moved and will reopen on October 31. (Due to internet connection issues) The web site inventory will be corrected to show only what we have in stock, and pick ups will be by appointment. 

Thank all of you wonderful customers for the last 33 years, under my ownership and 69 years in total!

Wolf Tooth 5-Spoke GXP Direct Mount Ring

Wolf Tooth 5-Spoke GXP Direct Mount Ring
Please select options


Wolf Tooth's SDM chainrings replace your existing spider and chainring with one clean looking, light weight, and stiff piece of machined billet. These come in 3 different offsets: standard GXP, Boost and BB30.

- These direct mount chainrings will replace your existing chainring and spider, which is attached via 3 bolts on the back side of the spider near the spindle. You will use these same 3 bolts to attach the Wolf Tooth SDM chainring.

There are 3 offsets: 0mm, 3mm, and 6mm
- 49mm chainline, 0mm offset for BB30 short-spindle cranks
- 52mm chainline, 3mm offset BB30
- 47mm chainline, 6mm offset for cyclocross and road cranks
- 49mm chainline, 6mm offset for GXP and long spindle BB30 Boost

Notes for use with Fat Bikes:
- If you are planning to use this on an X9 or XX1 fat bike crankset with a 190/197 rear hub spacing use the 0 offset ring.
- If your fat bike has a 170/177 rear hub spacing, use the Standard 6mm offset
