Discovered light weight inner tubes today lol.

Weighed all mine up. Regular tubes seem to be around 98-103g & the light weight ones 67g. 31g saving per tube not to shabby!
 
Has he just created it?
It will retrospectively go through your rides and add you to new segments that people create after your ride, but sometimes it takes a while for that to happen.
So you might find that you end up on top of that segment soon, or you might have to go and beat him.

He is top and i'm 3rd.

Latex rather than butyl?

Less hysterisis (sp?) as well so fewer lost watts. They loose air quicker though.
 
Apparently they're still butyl even come pre-talc'd!

Specialized Tube - Turbo Ultralight Road Tube with Talc

The Turbo Ultralight road tube, with new patent-pending valve and valve base, is proven in rolling resistance testing to reduce drag by as much as 13% per wheel.


> Talc in the pack for a better ride and fewer flats
> Large 4.8cm base prevents wear and tear on the rim-to-valve interface
> Threading only at bottom half of valve stem allows secure fit to rim
> Presta Valve only, smooth at the top for easier pump head insertion
> Thinner tube than our standard tube saves 40 grams of rotating weight
> 0.6mm thick

Yeah I love it, although cant stand getting a KOM taken off me, so if it happens I do tend to go out of my way to try and get it back.

same here! :) i love it.. makes me push harder which is always good! got one KOM afaik.. the guy in front was in a car or motorbike.. with average speed of 28mph and 52 as max.. :rolleyes:
 
I know 2 people that have recently gotten their first kom. I'm finding it so hard to fight the urge to go sprint them specifically to steal them.
