although it is very hard for me to part with the very beautiful and stiff rotor xc2, the weight weenie inside of me has taken control! i ordered the very expensive crankset from THM!
it will save up to 200gr, bringing the weight down to 7.9xxkg! a barrier that is very difficult and expensive to break with a full susser especially when it is ment for 90kg riders like myself!
the clavicula dp is a 2 chainring crankset and by default it has a weight limit of 85kg! because you can customize the cranks the way you want with thm, i opted for a higher weight limit, bringing it to 90kg!
these cranks have the best weight-stiffness ratio, and therefore they come at a price!
also they have race thoroughbred in them, being ridden by the womens beijing olympic champion Sabine Spiez!
crankarms+spacers+bottombracket =415
ta specialites chinook 42/32 = 60+30= 90
chainring bolts = 6
Total=511g (xc2 720g)
second upgrade brings just 50gr down!
the Cane Creek Aer Headset is only 50gr heavy in the ZS form that i will be using!
it has a lower bearing like any other headset but the upper one is a new thing! In fact it is a teflon bushing, very poshy named Norglide. so instead of a whole bearing you only have this special teflon coated bushing that does the job! of course there are disadvantages, and of course it is only road intended, but i will give it a try!
