New road wheels are centre lock, happy to be corrected but from what I can see using 6 bolt rotors and an adapter is the lightest and cheapest set up?

Currently looking at Quaxar Ultralight 6 bolts at 69g for 160mm from xcracer.com

Anyone using them or a similar set up?

Although not centre lock, im using those 160 rotors on my race MTB and on the rear of my anthem.

Probably 10% less powerful than the stock shimano's but it hasnt affected my riding.

I have hydraulic brakes on the road bike so I am not worried about stopping power!

In fact I could easily get away with 140mm rotors but would sizing down be easy?

for the tiny amount of weight difference get decent discs.

decent discs

Please free to state whats wrong with the quaxars or whats more decent? Seems an unqualified unecessary response otherwise.

Agreed... could you back up that statement poah? I've already stated they are for my road bike, its not like I am trying to stop an enduro rig with them...

I'm using similar rotors - The Alligator Windcutters - I've experienced quite a bit of flutter from the front which I guess can be attributed to the cut away braking surface - They do the job - look good - but I would prefer not to have the flutter . I'll probably go for something more conventional next time . .

I have shimano icetec Rotors and some lightweight Rotors from xcracer (Aries?) which are very light but I find the brake pad in my ultegra hydro setup, same as Xt I think? overhangs the rotor on the lightweight rotors which causes a slight burr as the pad wears down. This in turn causes the clearance to be tight and disk rub becomes hard to stop (unless I remove the pads and remove the burr)
I have no issue with the shimano Rotors

I've just fitted SRAM CenterLine X CL rotors, which seem pretty light and have good action under braking.
I'd not be keen to try cheap, lightweight rotors.

I've had these on my Anthem for 3 years, no issues. Haven't descended an alp with them though, nothing more severe than the Welsh trail centres and the Peak. 6g heavier than the Quaxars, but KCNC have a reputation for light stuff that works.

I've got the quaxars front and back (160mm) on my fat bike. They work fine in Welsh mountains with my oversized lump on board.

Quaxar with a DT Swiss adapter for the back worked well on my Trigger 29.
