I think the glue is coming off because you didn't degrease it. Something is stopping it sticking.

Standard practice for bonding ANYTHING: it needs the surface to be keyed and it needs to be free of grease or debris. So key both surfaces with 400 grit and thoroughly degrease it with an alcohol based degreaser. DO NOT use acetone because it will attack the resin in the carbon fibre, isopropanol is best.

This is how we bond all composites at work and your wheels are no different.

Zipp actually specify you can use acetone on their FAQ.

If the rim is new, wipe it down with alcohol or another solvent such as acetone, which is also recommended to remove old glue. The Zipp carbon rim can be cleaned with any solvent that will not harm epoxy. Zipp Carbon rims are ready to go at this point and require no further preparation.

I was sure it said not to sand the rims, but I can't find that anywhere.
 
Is anyone feeling less confident about tubs now? I know Berger's predicament might not be the norm but it just seems like a faff!

As I said a couple of pages ago, I dont think tubs are worth the hassle for daily use (but useful for racing).
To be fair though, I have seen people have just as much trouble changing a clincher :p
 
I think the heat must have got to me last night. Saw the red mist on my commute home yesterday. Someone in a car decided to shout at me whilst overtaking me, "Use the ******* cycle lane". I told them where to go, and made some unsavoury hand gestures. Probably over reacted, but I hate being told what to do, especially when I know I'm not doing anything wrong.

So, how do you guys normally react to such questions? I suppose I should just ignore such comments..........or cycle on the pavement :)
It's never happened to me in thousands of kilometers of cycling - I am not a militant cyclist like grudas, so I don't attract grief like he does ;)

Not really, I imagine it's like many things that with a bit of practice eventually becomes second nature.

I agree with touch though in that in my mind they're more suitable for race days and events. Saying that I have a friend who commutes on a Cipollini with Lightweight Meilenstein tubs and he swears by them. Just carries a pre-glued tub under his saddle.
 
I only plan on using the wheels to race on in the dry.

They will weigh a KILO less than my training wheels with the powertap hub, so you can imagine I am keen to get racing with them.

Losing all that rotating mass should be very noticeable.

1kg?!
Are your training wheels made of lead? No wonder you're so fast!

Not weighed my powertap hub but going by feel it's very similar to my cosmic carbone wheel (930g rear). Your training wheels must be at least 2.5kg?
That will make a massive difference! What wheels were you racing on before?

love you too ;) I do have a problem with road rage.. but I only when drivers put me in a dangerous situations! I do mistakes too but I have the balls to say sorry instead of screaming "you don't pay roaaaadd taxxxxxx" etc.

plus I cycle in london so the chance of getting into an argument is a lot higher..

due to traffic = frustrated drivers.
narrow roads = as above
loads of cyclists = boo
we don't pay roadtax(not a thing) etc

I don't think you can say they're pointless until you've actually used them...

that's true, I just think for my use they would be fairly pointless.

for someone who races it is a different thing and I can see the benefits they provide.

To be honest cycling in central Manchester I have similar issues with drivers (and other cyclists). So many idiots on the road that act like complete and utter turds. Inner city roads seem to encourage a lot of the bad kind of driving/attitudes.
 
I'm always careful to not go down the route of victim blaming but a lot of cyclists that end up in shouting matches with drivers is because they do some stupid **** themselves.

true, see a lot of this :) but generally I respect the rules, stop at red lights etc..

but when you get tailgated 5inches from your back wheel, cut off by a bus going 40+ down a hill TWICE and see the driver smiling it just drives you up the wall.

as I've said I make mistakes.. but I say sorry as it happens to everyone.

Fulcrum Racing 7 with powertap hub means they weigh about 2kg.

Add a force cassette, bontrager r3 tyres and skewers.

Compared to Zipp 303 which are under 1.2kg, a red cassette which is 100g less than a force, Ti skewers, and then the tubs are the same weight as a tyre/tube.

I've been using them to race on while I saved to buy some top end wheels instead of going part way with a 1500g or so set that I would want to upgrade again later. Paying for wedding things and new cycle clothing meant wheels took a back seat.

After all, power is power at the end of the day, just need to make more to keep up, all the sharp accelerations are the worst at the moment, getting those heavy wheels spinning!

After reading up ill use some 120 or 200 grade paper lightly on the wheels and a file on the tyres tape I think. I post on an Aussie forum too so will see what they suggest.

Just got the Campagnolo Zonda's fitted!

Hubs are strange aren't they, my old Ridley wheels were silent which I loved, but you'd like quality would be linked to noise, but I know that's not the case because I've been behind some really nice bikes on rides and their hubs are incredibly loud.

What does the noise (be it loud of quiet) actually mean?
