Small-wheel buyer FAQ

Route the right 349 / 406 / 451 rim request.

01

Product page, quote page, or fit finder?

Use this page to compare 349, 406, and 451 ETRTO rim families by size, width, depth, bead format, ERD, finish, and sample needs. Use the carbon rim OEM quote page when the target size, rim type, finish, quantity, and packaging requirements are clear, or start with the fit finder when the RFQ route is still unclear.

02

How do we choose 349, 406, or 451 ETRTO?

DeerCycles can help compare 349 ETRTO compact and folding-bike rims, 406 ETRTO 20-inch folding, BMX, or cargo rims, and 451 ETRTO performance small-wheel rims against tire volume, bead preference, finish, drilling, and sample approval needs.

03

Rims only or complete small-wheel wheelsets?

This page is mainly for small-wheel carbon rim OEM selection. Buyers planning complete private-label small-wheel wheelsets can use the carbon wheelset manufacturer RFQ path; buyers unsure which wheel family fits can start with the fit finder.
