new lwt disc rotor
Moderator: Moderator Team
160 mm for 72 g.
update.
i've ordered one of these Quaxar discs - not avaialble in able in 140 mm diameter
these look like they can be used with Formula R1 callipers (Hope SAW cannot due to the hollow rivet fouling the calliper)

ashima perhaps - seems they have 3 flavours: http://reviews.mtbr.com/ashima-2013" onclick="window.open(this.href);return false;
but not quite the same - I notice the disc in original post has "quaxar" stamped on it, a company that appears to make disc but googling has not so far found the one in the photo.
yep - is quaxar - see http://quaxarengineering.com/fluid/

arrived in the post today and was put on the scales immediately.
70g - unlike Hope SAW, it will work with Formula R1 callipers as the rivet clears the calliper.
won't be able to try it out until the weekend.
have to say the machined alloy carrier looks quite thin in places so I have to assume the manufacturer knows what they are doing ....

1.7 mm, same thickness as Hope SAW lightweight. ("normal" discs tend to be 2.0 mm)
Took them out for a short spin on an hill near by just to bed it in - have one 160 mm rotor on the front and it stops ok - no worse than Hope SAW. With use it should get better but I am not expecting "pikc your teeth out of the tarmac" stopping power. I reckon I will be replacing the 160/140 KNC Razor I am using by a pair of these.

Does the two piece rotor assembly really offer that much of an advantage in reducing heat transfer? I ask because the Ashima Ai2 Air Rotors come in ~62-63 grams for the 160mm rotors. Kiind of topic drift, but I have also read some good comments about Shimano's icetech rotors but obviously these are definitely not 'ww' at ~105 grams for 160s.
