  • Shimano GRX 400 10 Speed Rear Derailleur

    If you like to take on rough and challenging trails on your adventure road bike or gravel bike, the GRX 400 10 Speed rear mechanism will bring you fast and reliable gear changes, no matter how rough your route gets. Also, to ensure excellent chain retention and prevent your chain from damaging your frame, Shimano has added a gravel-tuned switchable clutch system. This can be turned off or on to suit the surface you’re riding. An ideal choice for modern drop bar bikes that can explore further than ever, this tough rear derailleur can work on up to 32T cassettes and is compatible with all Shimano 10 speed drop bar shifters.

    Wider Range Gravel Shifting

    Smooth and reliable for mixed surface shifting, the GRX 400 model helps you to get the best experience out of every ride. Shimano has also developed its design specially for gravel bikes by allowing for a wider range that's suitable for use with larger sized tyres. Taking your riding a step further, you'll also benefit from this highly efficient model's industry leading technologies keeping you in control. Behind the "click" you hear and feel every time you shift, its Shimano Index Shifting System technology provides you with light, precise and consistent gear changes.
