Reynolds Attack Clincher or Shimano 7850 Clincher for training and crit racing...which is better?

I do not know which is better but noticed that much heralded
Shimano carbon/Alu. sandwich rim is probably no longer
since Shimano came up with prototype "all carbon" low
profile rim much like Bontrager XXX.

no word about the shimano wheels, but i am currently demoing the wheels from the reynolds rep. the wheels are sweet. I have ridden 404s spinergy mavic cosmics handbuilts r sys and the reynolds are my favorite by far. The rubber he has them set up with is pretty weak but these wheels are stable and stiff. I found them comfortable and i really trusted them. I found 404s to harsh, but in comparison the attack clinchers are awesome. I was very against the idea of a carbon clincher rim because i really love the ride of tubulars but i have a feeling with michelin pro3s these wheels would ride even better. As i said before these are demo wheels so i am putting them through the paces. I have been regularly riding them on dirt roads and they have stayed true. When the right customer comes along this will definetly be my go to wheel.

Go 4 the Attack...

They are great wheels, the 2008 with the Revoution should solved their spokes breaking problem...

And in addition, you can always upgrade them using those excellent rims.

I change the hub to DT 240 ceramic, with SAPIM CX-RAY, got the best clincher wheels I ever roll on, reduce the weight to 1400g

Put the MVC32 decal

Udi.

I'm looking at these wheels on Wiggle.co.uk: http://www.wiggle.co.uk/ProductDetail.a ... heel%20Set

Are there any evolutions/years to avoid if purchasing? You know, the old "the '06s had crap hubs and the '07s all delamed but the 08s are spot on" kind of shop gossip that flies around. Thanks.

My only comment re: 7850 CLs vs Attacks are that there is no logical way the Attack rims can be as close to as light as the Shimanos which claim a sub 400 gram rim. Anyone ever weighed the Attack rim when doing a rebuild?

So many questions...

Attack rim = 430g

I have 5 months on the Attacks, they work pretty well with Swiss Stop Yellows. It probably makes more sense to go with the deeper Assaults (46mm) though.

Shimanos are ugly in person. Looks like they dipped a Mavic rim in chocolate.

I got a pair of the assaults two weeks ago. I've only done 200 miles on them but I really like them already. . Was a bit worried about the cheaper hubs but they have freed off nicely already, and are surprisingly smooth.

Think are only about 50grams heavier than the much more expensive DV46 Cs. Picked these up at my LBS for £800, which I think is really good value for full carbon clinchers.

Only thing I have a problem with is the brake squeal when using with yellow swiss stops - any suggestions on how to cure this? Do I need to angle my brake blocks differently?

Using the KCNC brakes, I moved to DuraAce brake pads, The noise stopped... read before that the Campagnolo pads did the same miracle as the Durace.

Does anyone have any experience with the 50mm 7850 Clincher wheels? They're obviously deeper than the Assaults and can be found for circa £650 which isn't bad. They are not superlight at something like 1650 grs a pair with a rim weight (according to Competitive Cyclist) of 530 grams so no 380 gr 7850-CL miracles here unfortunately.

One thing I'd wager is that the hubs are pretty sweet esp as they wear in. On cone/cup hubs is it common to sub out the SS balls for ceramic or is there not much in it?

That's exactly what I've done. Replaced with 3/16" ceramic balls. Hubs are smooth and also bombproof.

As for brake squeal, I use the Reynolds baradine pads that come with them on DA 7700 calipers. I set them up by clamping on the rim with the bolt loose, positioning them on the rim how I want them, and then tightening them down. This produces no toe in. They worked great for 300 miles, then they squealed like crazy, so I filed the pads with a metal file to rough up the surface. Since then, they have been flawless.

I have never been a big fan of toe in. If you toe in a set of pads, they will square themselves off fairly quickly. Then you have to toe them in more. It really chews through pads.

I'd choose the Shimano. I've seen quite a few Attack wheels that just weren't stiff enough. We've even had a few riders who opted to have them rebuilt using the 240 hubs, but if that's what you're going to do then you might as well just start with the MV32C.

And as for this "all carbon" Shimano wheel, it's not true. There are no full carbon clinchers in the works. There are more versions of the alloy/carbon wheels including a tubeless(though that's still a good ways off, and a reasonably priced Ultegra version for 2009-2010)
