After much fannying around, number crunching and head scratching I finally took the plunge this week and ordered some pro2 evos on crests (si @ progressive) for my inbred 29er. Got them set up tubeless this morning (cheers khani) with on ones stoopid cheap nevegals and just got back from shakedown ride....what a revelation un-bloody-believable difference in ride quality!! Knocked around 2lb off in weight and the bike is totally transformed...chuffed to bits! 😀
Just thought I'd share...carry on.
Dont forget to run them with super low pressure, i run20's in mine, makes all the difference...

I'm waiting for em to explode......

Khani, s'all good man, at least I hope it is as the bikes parked up next to the tele!
Well done, another one joins the flock.
2lbs?
What was on before?

2lbs?
What was on before?
I went for a 'try out' 29er build over Xmas and merlin were doing a silly wheel set deal at the time, c'dale rims, Deore hubs etc for £80 or so. 2400g without tape and skewers. Hoops weighed 1690, lost the tubes, lighter tyres ....win!
It had those cheap merlin 29er Cannondale jobbies,( they weighed 2.4kg 😯 ) with wire bead kendas an tubes, now pro2 evo/crest tubeless with folding bead kendas, 2lbs difference at least..
Edit wot speedy fingers up there ^^^ said ..
I saved perhaps 1lb moving to Hoops and Spesh 2Bliss tyres and really notice the advantages. No surprise you're chuffed.
sorry for being a complete tool but what happens if you're in the middle of nowhere and the tyre just rolls off the rim? Or does that just not happen?
Inner tube backup? or what?
And how big thorn for example would be able to be saved from destroying the tubeless setup - what I mean is if I put a nail through, then pulled it out, would this be recoverable?
If you'd seen the faff we saw today with this revolutionary tubeless crap, you'd turn the light back off...
faz083 - Membersorry for being a complete tool but what happens if you're in the middle of nowhere and the tyre just rolls off the rim? Or does that just not happen?
It does happen, but very very rarely (and only if you're using inappropriate tyre pressures). So yep, backup tube.
Nail through and back out might or might not seal (nail stuck in it usually will seal). Any tear or cut that'd destroy the tyre for a tube will destroy it for tubeless, any that you'd still put a tube in you can fix with a patch.
They the 2.2" Nevegal's you got?
I had a pair of them on my 29er, took DAYS to bloody seal tubeless in the end! Eventually managed it, but the sidewalls were so porous I kept having to top up the sealant over and over again. Mind you, just set a 2.2" Rubber Queen up tonight, must've used 1/2 a pint of sealant in that it was so bloody porous too!
Sometimes makes you think "sod it, I'm buying proper UST tyres from now on".
FWIW I got my rubber queens to seal up with just my usual 90ml-or-thereabouts. Though it did take about 2 months! Constantly foaming before that, they stayed up for long enough for a ride so I just carried on.
Fenred - are the tyres you're using tubeless specific?
I've just got hoops with stans flow rims, considering going tubeless but not sure whether to try with a normal tyre first!
Little bit of KY on the bead (or Fairy liquid) then hold the wheel off the ground while inflating; works every time.
Tell me your using stans fluid? I'll not sleep at night else *concerned smiley*
EDIT: To maintain inflation bliss, you'll need to remove the tyre and pull the cured stans off the bead area + the rim itself...depends how quickly you go through tyres.
Please excuse the partial hijack of this thread, but I'm about to make a similar move to tubeless. Treated my self to a set of Hope hoops Crests that I've been running with tubes over the winter, but I'm now looking to go tubeless. Has anyone any experience of using Spesh's 2Bliss tyres on the notoriously fiddly Crests? Looking at running the Captain and Fast Trak's...
Thanks.
Daveyboy what was this faffage? Trailside repair? They're possible but I just bang a tube in, especially if in a rush (or a group 😉 )
Normally less problems but messy when it does go wrong (and if u don't carry a spare tube ur a bit of an idiot) been great for me, 1 mate only flats about once a year so not much point for him
If you'd seen the faff we saw today with this revolutionary tubeless crap, you'd turn the light back off...
Were you watching me?
Thanks for the posts all.
Blanket response I'm affraid as busy morning...
Yep they are 2.2 nevegals, folding bead:

Stans valves and juice. I was very hesitant about going tubeless and which tyres to try to get on having read some of the horror story threads on the interwebz but the tyres were no harder to get on then conti's on my american classics, used tyre levers to pop the last bit on as per normal with tight fitting beads/rims.
One thing I would say is that without a compressor I wouldn't even attempt it, how people do this with a track pump for blowing the trye on initially is quite some feat 😯 Do what I did and recruit a mate that has done it a million times before if you're uncertain.
The good news is they didnt explode overnight, no leaks that I can tell and still got air in them.
Riding today so lets hope it stays that way 😀
HTH
Spesh 2bliss tyres go on a treat on Flows/Crests
Bit more weight hiding in there, those tyres are like 850g or something bonkers.

Yep, you're right there Toasty, 807g on my scales but my god they grip like shoot to a blanket in the claggy clay round here... 😉
