Tubeless setup

Antm81

Probably been asked a thousand times but looking at setting up my giant s-xc 2 rims tubeless. I've heard they are tubeless ready and others have said they aren't.

Currently looking at a set of superstar valves and tape. Question is which sealant and how much will I need. The rims are also 650b.

If it helps I'll be fitting bontrager team issue xr4s at the same time.

Thanks

Roughly 60 ml per wheel of Stans sealant. Have done same tyre on crest and mavic rims using stans kit , went on fine with a track pump.

It helps a lot to seat tubeless tyres if you squirt some soapy water around the bead - get one of those little spray thingys from a garden centre and put a little bit of fairy liquid in with some water makes it easier to squirt on. When inflating I find it best to inflate it first without the sealant in until it goes bang - which will make you jump - this seats tyre well. Then deflate and open a little bit of the tyre up and pop sealant in and re-inflate

poah

my XR4's went on to my UST rims no issue. having used superstar tape and valves I'd suggest trying gorrilla tape and DT swiss valves instead.

These ones?

Say road with mtb option unavailable.

In terms of sealant, is joes up to the job and how much do you guys recommend per wheel?

poah

yeah those are the valves I used for my bro in laws bike, no idea what the difference between road and MTB (maybe length) - its actually the road ones I've got.

only ever used stans sealant

Gorilla tape, valves and joes sealant on the way (bigger bottle for less money and I'm from Yorkshire so I'm tight).

Thanks for all the replies, tyres have been on the rims over night so looking at setting them up tubeless today. One last question though, the blue giant rim tape that's already in, should I remove it or put gorilla tape over the top?

Thanks

poah

I put the gorrila tape in without the normal tape there.

Left the original rim tape in on the front (was before you posted), had to take it out of the rear (losing air from the spoke holes).

Both now inflated and seem to be staying that way, even held pressure without the sealant.

It should hold the pressure without the sealant.

It won't, however, hold pressure without sealant if you get a puncture!

Not necessarily, that's the difference between UST and "tubeless ready", the former is an airtight carcass, the latter just has a reinforced bead to run tubeless, but no guarantees about the porosity (or not) of the carcass - some will be airtight, some won't.

lostboysaint

Fair enough. Never had a Bontrager tyre with porous tyre walls (XR4 or Mud X/Team XR Mud) before, always been perfectly airtight, hence the comment.

Didn't deny it, just said it's not a guarantee, and if you did have a leaky one (I've had Mud-Xs with leaky sidewalls) it's not duff, that's how they're designed.

Antm81

Yeah they're not UST, they are tubeless ready, not sure the rims are though. There's plenty of sealant in there too. The XR4s do state they have to be used with sealant.

Tubeless ready is pretty irrelevant for rims, just about anything can be converted!
