Need the red Vittoria extensions and you need to buy glue. No you cannot swap extensions.

YES you need to buy glue, its cheep so just get some from your bike shop.

you can swap the valve extender from tyre to tyre but for convenience get two and leave them on.

The 404's come with valve extenders and they will be fine. There is no glue with the tyres, purchase this separately.

yeah mate, you need to buy some glue too. best off buying two valve extenders. save you time if you flat in a race, and the flat is the tyre which doesn;t have the extender on it...

you need two

You need glue which isn't included. I prefer tub tape - the Velox is good but Tufo is better - both from Wiggle. Search youtube for videos of how to fit a tubular tyre. You need a valve extender for each tyre and it stays on the tyre - no swapping after you've blown your tyre up! HTH

hi, kenny from dubai here! you will need 80mm at least. i recommend spending a few extra $$$ and getting high quality tubbies - otherwise they puncture too easily and it's expensive to replace (also depends where you ride and for what events-melbourne was fine but i have had 2 flats in 6 weeks in dubai!!). do your research but the italian ones are generally great and have v.good revues, cheers, kenny

Vittoria Corsa Evo CX's 23's or 25's on rear wheel if you weight is 85kg +. 80mm valve is ok , these tyres are fitted with removable 42 mm valves ,buy the vittoria 60mm removable valves

I have campy bora ultra two's they came with a 40 mm valve extender , I replaced the vittoria one on the tire and installed them on the extender , they etend the red valves out 35 mm out of the wheel,

I have an old set of spinergy carbon 4 fin wheels which I think have a similar profile.
I used 40mm extensions which are fine.
Just take out the new long valve section which screws out right at the tyre, insert the extension and then insert the valve section into the extension.

Yes. Not sure what you need for Zipp 808's
36mm
42mm
60mm
80mm
110mm
available

You can remove the valve on this tub and put a long or 2 shorter extenders on upside down then screw in the red valve that it comes with. depending on how much valve you want hanging out ,I guess you would use around 70 to 80 mm of extender.

These will do you fine. You'll need valve extenders though. I recommend the Topeak or Vittoria ones as you can put these together to get a long enough valve for your rim depth.

I find around 110 - 120psi is best for me. I use the same pressure road racing or time trialling. They will take up to 200psi but i find a little bit of suppleness works best.

Recommended pressure is between 8-14bar, what is best for you depends on both your weight and what you are using them for.
For example I'm 70kg and run them at 8-8.5 bar for road and crit racing in the dry. I tend to drop the pressure slighlty if the roads are damp.
Best thing to do is experiment and see what you prefer

You need to get the Vittoria valve extender.

I am using the 80mm extender with a similar depth rim (Zipp 404) and I think you'll be fine with that.

I thought similar. I had a fast forward FP6 and thought exactly that, i even tested it before putting it on the rim and it inflated/deflated fine. However, my LBS (who were gluing the tyre) said that they cant do it that way and that i had to order the longer vittoria valve. Not sure exactly why.

Yes the valve stems are removable as i had mine replaced to fit 60mm rim depth.

If you have clincher hook rims then use the Continetal Supersonic. If it's a smiley hollow rim then it will be tubular

Yes they are available. Irun them on a set Lightweight Obermayer's

They are compatible with any tubular rim.
