Tubs??

AndyD2574

Got the chance of a set of 404 tubs (not firecrest).
Use Mavic cosmic carbone sr's at moment on my S3. (clinchers).

Could save about 500 gms with a set of tubs but never used tubs and dont quite understand what happens if you puncture?

Can you fix it roadside????

You'd need to carry a spare tub or two if using the wheels for club rides etc - negates most of the overall weight saving (although the weight is being moved away from the rims so still worthwhile). I've changed them at the roadside in years past but to be honest - with clincher tyres being so good these days, i'd only use tubs on a Time trial bike or dedicated road racing wheelset now

Do you race or compete in TT at a decent level? If so, go for it, if not, save your money. 404 are not a good allround wheelset, the only attractiveness are the big logos, but you can always get pro kit for that and tubs are an expensive option if you plan to puncture 5-6 times per year

Tubs rock - I use them on the good bike for training and racing all summer. never had an issue (he says tempting fate).

I have just fitted some Cosmic Carbons for a weekend trip away and although they roll nicely and sound good they aren't as nice as tubs - rolling or feel (didn't want to risk carbon wheels when I am an hour long boat journey away from home if it rains and ends up ruining my weekend due to no brake syndrome). They'll be coming off the minute I get home and going on the fast summer trainer bike though.

Re puncturing - either carry some Pit Stop or a spare tub in a back pocket - it takes 3 minutes to change one at the roadside. Stop. Take wheel off. Rip off old tub and throw in the nearest garden. Put on new tub. Inflate. Go.

Re Zipps: if they are a good price and in a good condition, then go for it - if anything the psychological effect of your bike lookinmg well smart and deep rimmed will add 2mph to your top end and 5mph to your ego. Alternatively, sonmething like a Planet X carbon 50 for c.£330 will do the job very nicely - good price, light strong wheel, good all rounder. Probably lighter than the Zipp as well.

And that's 60 pounds for a puncture... then people go on about the cost of entering a sportive... :shock:

If I go for the Zipps will I have to change teh pads on teh S3.
My Mavic sr's have a alloy braking surface with a 52mm carbon rim.

Would I need to get carbon specific pads.

Last question........I would put teh mavics onto my RS and I run campag on that........is the freewheel easy to change from sram to campy??

Cheers for advice lads!

Amend then to rip off tub and stick in back pocket to have a look at later with a view to repairing.

If you worry about the cost of everything then you'll never have anything nice. Oooh - I don't want some Zipps, I may hit a pot hole and break them - I'd better buy some Planet X model A wheels in the sale when they are £6 and if I break them at least I won't have spent as much. I won't cut the steerer down on my carbon forks because one day I might want to sell them but I don't know when or even if so so I'll just put up with it. Why drink Petrus when you can drink Co - Op own and get the same result?

Yes, you'll need to change the pads to carbon specific - wide range of choices and prices, however I would recommend Swissstop Yellow - expensive but work execllent and last ages - see the thread two or three lines down re this.

Re freewheels/hubs - can anyone else advise? I can't see it being difficult but may cost £60/70 at a guesstimate for parts. Did I read somewhere about a Miche cassette that will work with Campy/Shimano/SRAM or did I dream that?
