32ER buyer FAQ

Questions before selecting a 32ER MTB rim.

Product page, quote page, or fit finder?

Use this page to compare 32ER MTB rim families by 686 BSD fit, inner width, strength tier, offset, ERD, drilling, and sample readiness. Use the 32ER MTB quote page when riding category, tire range, width, offset, weight tier, finish, sample timing, and batch quantity are clear, or start with the fit finder when the right rim or wheelset path is still unclear.

What does 32ER / 686 BSD mean for an MTB rim program?

It refers to a 32-inch mountain bike wheel platform with a 686 mm bead seat diameter. For MTB brands, the main checks are tire support, fork and frame clearance, strength tier, offset, and sample validation.

Who should use the 32ER MTB product page?

This page is for bike brands, wheel brands, frame brands, sourcing teams, and prototype teams comparing 32ER MTB carbon rim models before sending an OEM or private-label RFQ.
