What to Know

Components & Parts

Chain Reaction Cycles stocks a very broad components range — groupsets, derailleurs, brakes, forks and suspension from Shimano, SRAM, RockShox and others. The site lists compatibility details, part numbers and technical specs to help DIY mechanics and workshop techs pick the right parts for upgrades or maintenance.

Wheels, Tyres & Accessories

Wheelsets, tyres and tubeless systems are a big focus: options for XC, enduro and road race wheel builds plus braking rotors and hubs. CRC sells complete wheelsets and spare rims, plus tyres from major makers, making it straightforward to spec a performance upgrade or replace worn rubber.

Clothing & Protection

The clothing selection covers jerseys, bibs, jackets, gloves and protective gear across sizes and seasons. Brands for performance road and mountain apparel sit alongside budget options for commuters. Size charts and product descriptions help choose fit; layering pieces and protective kits are available for year‑round riding.
