Weight of Stans No Tubes

Stu 74

Just fitted a 2.5" Dual Ply Super Tacky Swampthing as a front tyre. Went for a spin round C Y B yesterday and on it's amazing on rocks, roots and anything that is in the downhill direction.

However the 1150g weight of the tyre combined with the 225g inner tube is noticeably harder work going up hill

Was thinking of converting to tubeless anyway but was wondering how much the Stans No Tubes System weighs.

Had a search but no luck. Anyone know?

Cheers

Dual ply tyres will weigh a ton, there's your problem.

I would guess no more than 100g per wheel,depending on how much sealant you use,so there an easy 250g weight saving to be made.That would be a lot on an XC bike with lightweight tyres,but maybe not so noticeableon a bike with such lardy tyres.

100g of latex plus the rim strip, so about the same as a spesh light innertube. 180g ish per wheel. Over 1kilo for each tyre - that's heavy.

That tyre is heavier than a lot of front wheels - bit overkill for CyB really isn't it?

Sealant in a double ply tyre is a bit belt-and-braces so far as punctures are concerned anyway, maybe.

Thanks for the replies.

Just to clarify, I'm running a 2.5" Dual Ply Super Tacky Swampthing as a front tyre (1150g) and a 2.35" Single Ply Super Tacky Swampthing as a rear tyre (725g). I originally had the 2.35" Single Ply on the front (2.35" Nevegal on the rear) but its more like a 2.1" and I missed the extra cushion of a wider tyre, hence the 2.5" (which is actually like a 2.35")

Personally I thought the tyre was very good on the wet rocks and roots at C Y B, really gave me the confidence and grip to tackle things quicker. However, I can confirm that this tyre combination will definitely not be used for Llandegla again!. Went there tonight and couldn't believe how much the tyres slowed me down, gave me a good workout though!

Think I will leave the Swampy on the front and try sticking the Nevegal back on the back to see if this strikes the balance between grip and speed or maybe I will just use the Swampthings when I go to rocky places like C Y B. Will feedback how I get on!

100g of latex :shock:

I used about 20ml per tyre on the last few tyres I've set up and 10ml on proper UST tyres recently. Every time I remove the tyres there has always been a bit of fluid still slopping around.

My Joes strips were about 100g as well, making it about the same weight as a light latex tube or something. Good system, I wouldn't use it if you're in doubt about tyres though, swapping is a pain. Still using one now on the 2.4" Nobby on the front of my Meta (635g :? wider than 2.35" High Rollers).

Well did Llandegla this morning with the 2.5" Dual Ply Super Tacky Swampy still on the front and a Nevegal back on the rear. To my surprise (and delight ) the bike was a lot quicker. It seems that it was the 2.35" Single Ply Super Tacky Swampy on the back that was slowing me down, not the heavier Dual Ply Swampy on the front!

In fact I would say that it was probably no slower than when I had the Nevegals on both the front and rear.

I guess this is because, when pedalling, most of your weight is on the rear tyre, not the front tyre. It must have been the super tacky compound on the rear tyre that was dragging the bike back.

So if I get a fast rolling tyre for the back (Maxxis High Roller 60a?) I should have front end grip and speed

If you intend to change tyres regularly for different destinations or any other reason (commuting maybe) then I wouldn't bother going tubeless.

Too messy and requires a compressor not to be a complete pain in the ar$e.

I've got a Stans kit but have given up for now
