mavic cosmic elite ust 2018 v ksyrium elite 2017
right folks, clubbie rider here, dont do races, just weekend runs and during weeks . over varried road conditions and weathers, have two otpions for wheel upgrade , as above, both with tyres included, unused taken off new bikes, £200 for the comsics or £300 for the ksyriums. What would you take, is the extra £100 worth the less weight but not tubeless otpion? Or go cheaper (and bit more blinger) tubeless option?
