Mudhugger Rear is perfect for these wet conditions

As a mountain biker I'm not a fan of mudguards but this wet winter has broken me. I ordered and fitted the mud guard and it does a great job, I wish I'd fitted it months ago

Tried to replace my front chainring but wanted to put a 48 tooth ring on, after long search I found sprocket and gear with the perfect part.
Good service and delivered on time.

Great upgrade to make tubeless maintenance easier!

Great quality and very pleased with them. The Pro-Lite wheelset look really good and were very easy to set up - transfered cassette from previous wheel, fitted valves, put on tyres, added sealant and pumped up without any issues. Good fit on bike - did not need to reposition disk brake calipers for either wheel nor re-index gears. I like that they have sealed bearings and they rotate much more freely than the wheels they replaced. Bought to upgrade my 2015 Giant Talon 0 wheelset as the standard wheels were not tubeless and took a lot of maintenance to keep them working.
