would I notice a difference with hope rims?

sefton

would I notice a difference if I swapped my Shimano mt65 wheels for something a little lighter like the hope pro 2's?

or should I save my money?

here's my bike (easier than listing all components):

Depends what you actually go for and what stuff you ride, lots of diff. Pro2 builds about, with a tyre change as well (don't know what your tyres are yet?) you could prob save over 1lb in rotational weight.

MT 65 are quoted as 1800g and are already tubeless compatible.Not sure you`d save that much by going for standard Hope Hoops,unless you went for XC3.....

Not sure what tyres you have,but you could probably achieve a similar (200G) weight saving for a lot less,with lighter tyres.

Are you still runnning yours tubes too?

pastey_boy

stick with the mt65,s unless you go for the xc3,s with stans crest. set your wheels up with some light tubeless ready tyres and your off. the mt65,s are very easy to use with tubeless tyres, i had a set with specialized captain tyres which were just under 600g a apiece. they performed awesomely and felt really light. the shimanos are pretty tough too and have easy to service bearings

jairaj

agree with everyone else. The MT65 are a great wheel set, very reasonable weight and good strength too. Unless you spend loads of money you won't get much of a saving.

I'd be looking at tyres too, Specialized Captains will be great when it gets to spring but for me not the best in the winter. Otherwise Schwalbe have got some really light and tubeless ready tyres to check out too.

sefton

how much will I save going tubless then?

stu8975

Depends on your current tyres??? and what you change them to. Schwalbe and Conti now have tubeless ready tyres that are a fair bit lighter than their UST jobs.

pastey_boy

ive just stuck a pair of bontrager xr2 team issue 2.1 tubeless ready tyres on my bike they weigh 560grams each and come up pretty big for their size. not really a mud tyre but great for trail centres, the girlfriends got my old mt65s shod with specialized eskars 2.3,s running tubeless again nice and light but probably on the limit width wise,

weight of 2 tubes, 2 x 150g= 300g

Though you may need to add some sealant,so probably nearer a 200g saving compared to tubes.

For tyres something like the new tubeless ready Schwalbe Nobby Nic Pace star Evo is 470g in a 2.1,which i am willing to bet is lighter than what you already have.

So 2 x 2011 Nobby Nics are £80 from Next day tyres.

And likely weight savings might look like this

Existing tyres 2 x 600g= 1200g
Nobby Nic 2 x 470g= 940g

Saving 260g

Tubes 300g

Sealant 100g

Tubeless Saving 200g

Total saving= 460g
Not bad for £80.

Sensible tubes can go lighter- Schwalbe XXlight is 100 grams give or take and still durable and patchable. Stans recommendation for sealant comes out at 60 grams for a 2.1 tyre, plus the valve of course which is about 6g each. So yep there's a saving but not neccesarily a very big one. I would recommend it anyway though I'm on the fence about tubeless on non-UST rims but for you, it seems a waste not to really.

sefton

just recieved some tubeless nobby nics 2010.

the actually weigh in at 678g & 658g

Yes UST tyres are heavy, should of ordered the new Tubeless (TL pacestar) ready tyres, prob would of saved approx 1lb in weight

sefton

dam!

what's the difference other than weight?

are ust more robust?

stu8975

Normally thinner sidewalls, never had any probs with the Spesh 2bliss tubeless ready tyres I've used over the last couple of years. NN claimed weight are 475g each for TL ready (2.1).

See if you can return them or exchange, just say you ordered the wrong ones, that's if you haven't used them yet.

sefton

arh, going to cost a bit to send them back and them an extra £15 for the 2011 versions.

do people still take a tube as a back up (incase the side wall gets slashed etc)?

got the doc blue sealant too...has anyone used this before? should I add it before inflating or through the valve once inflated?

Oh yeah. Some people will tell you you'll never get a puncture with tubeless, but it's just nonsense, it does happen.

stu8975

Use sealant as well.

+1 for swapping to Spesh Captains. Saves weight, reduces (not eliminates) punctures. Reducing weight at the outer edge of a wheel will give you the most noticeable performance advantage, so yes, a good thing.

Just if you're heavy, or ride hard be very wary about going for ultra-light rims, particularly at the rear.

As everyone else said, you'll have to spend a lot of wedge to get an appreciable benefit from different wheels, going for a light-ish set of TL-ready tyres will give you more bang for your buck. In 2 years of running TL (mostly with the Captains) I've had 2 punctures; 1 was an 8 inch nail (yes, 8 inches long), the other was a sidewall slash from a very big & tough broken glass bottle (the joys of commuting on Towpaths). Much better than the 1 a day I got before though...

If you really want to go for lighter wheels, and are a light rider, check out the Hopes with Stans crest or if you're not so light, go up in price & look at the Mavic Crossmax SLR.

I have a set of Hope / 721 wheels. Is it possible to make them tubeless?

I have Bontrager MudX tyres which I believe are tubeless ready.

They currently have slime tubes (not my doing they're insanely heavy) and trying to lighten the wheel setup.

Sorry for the Hijack. :oops:

sefton

OK sent the UST's back

just received the 2011 pacestars

claimed weight: 470g

they both actually weighted exactly 508g

GREAT SERVICE FROM NEXT DAY TYRES BTW!!!

@LeeJDavies

Most likely. I have run a couple of sets of normal (ie. non-tubeless) mavic rims as tubeless using Stan's rim strips. Much more difficult to seat than proper TL rims (mucho swearing involved, defintely get either compressed air cans, or go down to the local garage airline) but once on they worked fine.

However, I never tried specifically with 721s so no guarantee! Good luck, IMHO, tubeless is worth the hassle.

dennisn

I think you'll see a major difference. The rim will say Hope instead of MT65.

sefton

ok fitted the 2011 nobby's on Saturday (no problem at all)! did it with a track pump).

they are still losing a little pressure. I've re inflated them around 6 times now so hopefully they'll fully seal soon. the instructions said several times.

they are on the light side (just hope the sidewalls hold up)
