The aluminium looks sweet underneath. a nice smooth brushed finish, no sand blasting. Find a car sprayer supplier and get the paint stripper from there. It is the most disgustingly nasty stuff ever. DONT get it on your skin just a little bit is agony. However it gets the paint off better than any DIY store stuff and i got it for ~£15/5 litres.
However has anyone noticed a difference with handling, due to the tyre rolling on these rims. Ive been using shwalbe rocket rons and ralphs on non tubeless rims, no problems with as little as 15 psi in the ralphs and 20 in the rons. However on these ztr rims it just all felt like crap. I had to run them way harder than normal, for the tyres not to squirm and roll all over the place. The rims could be slightly narower as well as lower wall height.
How much weight did you save on BB7s? Yes it was probably worth my time, it prob took about 1 hr for 4 rims.
Couldn't tell 'ya. Probably negligible amounts I know just the caliper itself, without pads was 134g There were two bolts that also could have been easily replaced with Alu/Ti with little or no difficulty. ( http://forums.mtbr.com/brake-time/defin ... 65630.html
