Cool. I'm building a set of Stans 340s w/ DT Swiss 240s. Ive had really good luck with other Michelin tires so I would like to stick with the brand. Compared to other brands I have used, Michelins are super premium quality all the way around. So how much sealant should be used? I read 50ml is a "starting point", but what is optimum? thanks again.
I too have had good luck, both as conversions with Stans strips and on Stans rims with Michelin Jet and Mud. I've typically just used 2oz - which I guess is 59+ml, and that's lasted as long as a season but was dry by then. But usually the tread is worn out before that.
Thanks for that. I'm buying a couple of latex tubes just in case, but using a Stans rim I have high hopes even though the tire is not technically tubeless ready. The tires that state tubeless ready, what exactly is different about the bead? Thanks.
The bead is not so different, but the casing holds air without sealant. Often that adds a bit of weight to the casing though, and I'd want to add sealant anyway for prophylaxis. Mich should work great with stan's rims and 2 oz of sealant!
That crossed my mind too. If you're adding 100g of sealant you haven't really done much in terms weight considering latex tubes are pretty light. Sure you'll decrease rolling resistance, but a tube to me at least is just a little more security. Another thing, if you were to flat or burp or whatever out on a ride, what is the process as far as airing back up? What kind of spares do you carry and how easy is it to air a tubeless with a mini pump? Thanks again.
hey there. if it burps and reseals, a mini pump will be fine. compared to tubes, yes, a latex tube is similar but a good tubeless setup will be more reliable and allow you to go lower than with a latex tube and will be more puncture-free. worst case, you can just throw a tube in there and remove the valve.
the tubeless beads do have a slightly different shape and are designed to not stretch. the old hutchys had a bead inherited from road tubeless which needs to have a stretch-free bead so it won't blow off in high pressure. but that's not necessary in low pressure systems. more important is that the bead is tight.
Hutchinson has reworked the bead for this year - we just got some in. Stay tuned.
but they're still that awful gray color right (hutchinson piranhas)? on that picture on stans home page, are they saying that tire with the sidewalls touching is still inflated? so the sealant will seal that large of a gap? i thought it was mainly for nail-head sized punctures...
