This cassette is amazing and works so well with the wireless SRAM AXS system. It’s been on my son’s bike for roughly 3 months and then taken off as we’ve gone back to cabled gearing because he races and we need to be able to mend the derailleur on race day which is tricky (impossible) with the wireless one. These retail for £270 brand new so I reckon £150 posted is a great price seeing as it’s barely been used (please check the photos for actual condition; if you need any more pictures please do just ask). We make a note of the serial number before sending. As always please do ask any questions. This is a USED cassette and we do not accept returns as it’s not new. Grab yourself a bargain!
