Affiliate Disclosure

How it works

When you buy a trainer, freehub body, cassette or adapter through some of our links, we may earn a commission. This costs you nothing extra and does not change the price you pay.

As an Amazon Associate we earn from qualifying purchases. We may also participate in other cycling-retail affiliate programs.

Our editorial independence

Compatibility verdicts are determined by the data (axle, freehub, cassette), not by commissions. We do not accept payment to change a fitment result, and an affiliate relationship never makes a trainer appear more compatible than it is.

Verify before buying

Prices and availability change. Always confirm the exact part and current price on the retailer’s page before purchasing.
