dracs Posted January 23, 2012 Posted January 23, 2012 Having spent some mula on race wheels and tyres it seems to make sense to stick in some light weight tubes as well.... Any downsides to this? I am thinking if you are going to puncture from something penetrating your tyre, the thickness of the tube is unlikely to make a difference?

no calves Posted January 23, 2012 Posted January 23, 2012 i have some michelin latex aka condom thickness tubes i race with when im not on my tubbies
dracs Posted January 23, 2012 Author Posted January 23, 2012 thats what I was wondering... Personally i can't see me noticing 50 or 60 grams per tyre (which is the difference I think), BUT that said it has to be one of the cheapest ways to save 100g - to save that on a wheel or cranks and you can easily be talking a grand or 2 or more in many cases...

Anyway, I ordered som maxxi extra lights and they arrived yesterday. Must say they are noticibly lighter AND also MUCH smaller (rolled up) than standard tubes which makes carrying spares that much easier as well... Going to give them a spin at the fast one this Sunday, mated to my new (and also fast but potentially fragile) Vittoria Open Corsa Evo CX Tyres and fulcrum racing 1 wheels (both of which I picked up for a steel from cwc last month...) Sounds like a quick combo (as long as I don't spend half the race on the side of the road fixing punctures )

dracs Posted January 30, 2012 Author Posted January 30, 2012 (edited) So, guess what - i punctured after 5km's!! First puncture in a race - ever! Coincidence? After a VERY slow change (really battled with the tyre for some reason)... I was on my way, and, fortunately i managed to survive the rest of the race with no more drama... (after the early puncture I was thinking I would be begging for tubes before long...) So, ja - I am thinking the odds are the tyre and or tube clearly places me in position of more risk of punctures, but on the other hand maybe it was just Murphey and bad luck.... Right now I am leaning towards giving the tyres a few more chances but ditch the light weight tubes... Edited January 30, 2012 by dracs
