A tuned DT centerlock adapter (11g), 12t aluminum cassette lockring (6g), and a 6 bolt Scrub Components rotor (56g) = 73g. You're ahead on the bolts too, as you don't need them with this adapter, so 6g minimum saved there.

or even lighter! my rear brake set-up is 69g with a 160mm rotor +7g upfront with 180mm rotor.

Scrub have even lighter rotors on the way soon, seen pics of a prototype 46g 160mm rotor with a magnesium spider

36g for 160mm rotors would be phenominal!

ianthom, sorry back to topic

both Hope & Formula manufacture lightweight centrelock rotors, but best to check with their websites for the size you need to get weights

Shimano owns the centrelock patent, the current XTR RT97 centrelock rotors are abit hefty compared to what's available from Hope or Formula @ approx 162g for 180mm, 140g for 160mm & 111g for 140mm (rear only)

hope that's of help

Quick question - where are you guys getting the "tuned" dtswiss adapters that weigh 11 grams?
