Roundagon vs. Clean sweep

[Mongoose]

What do you think of Avid Roundagon and Cleansweep rotors? I got a new bike with Juicy 7's and clean sweeps and the breaking is solid. The local bike shop built me a new set of wheels with roundagons and now the breaking feels weak. I road the bike for two hours in Wompy to break things in, but the rotors still don't have the stopping power the clean sweeps did.

Do I need to break the roundagons in more? Or should I swap rotors between my wheels?


btw, the Bike Barn is great! They couldn't convert my old tires to tubeless so they gave me an awesome discount on some new tubeless rims and tires!

I have Cleansweeps, 3rd set and I always go buy if it isnt broken dont try and fix it, UNLESS SOMETHING WICKED SWEET COMES OUT.
I have never tried the Roundagons.
But I have a question. Are you talking about the Bike Barn in Manchester NH or one in Mass somewhere?

I replaced my 2005 Avid Roundagon rotors with the cleansweeps, and yes they work better, no noise either.

Ditto for me. Was running the Roundagons, and thought they looked better, but the noise(lack of) and braking was noticibly better with the cleansweeps.

Clean Sweeps are def. better. Right now my 3 disc bikes have Roundagons and I miss my old Clean Sweep rotors..

That's what I figured. I'll swap the rotors between the wheelsets today. Is loctite required?

The Bike Barn I mentioned is the one in Whitman, MA.

I'm off to find a torx wrench...

Is loctite required?

Only if you want the rotor to stay attached to the hub:-). Avid rotor bolts have loctite pre-applied, but you should use a drop of low-strength loctite when re-installing.

Is it normal for the rotors to be out of true when moving them to a new hub? The first rotor I put on and noticed it was badly out of true. The second rotor I put on and lightly bolted it to the wheels, thinking I may have over-torqued the other rotor. It was still a little out of true. It seems odd since it was perfectly fine on the other hub.

Roundagons are for mechanicals and clean sweeps are for hydraulics. Mechs don't need ventilation becuase there is no fluid to boil.
I run both on mechs and notice no difference once broken in. On Juicys it's bound to be different.

I have Juicy 7's on my bike, maybe that's why the clean sweeps work better then. Three adjustable wrenches and a few hours of work straigtened out the rotor. After that I went for a ride. So far these tubeless Continentals are great.
