Affiliate disclosure

How this site is funded and how we choose what to recommend.

Updated 2 November 2026

PainCave Insider is reader-supported. When you buy through some links on this site we may earn a commission, at no extra cost to you. As an Amazon Associate we earn from qualifying purchases. We may also earn from other retailers and brands.

Commission never decides what we recommend. Our guides are based on manufacturer specifications, UK retailer listings and independent tests by established cycling publications, which we link to. Where we have tested a product ourselves we say so.

Prices are guides checked on the date shown on each page. They change often, especially in November and January, so always check the retailer before you buy.
