Tubeless rims, rubber type valve: WARNING...

[nastro azzurro]

I know this has cropped up before, with the valve coming away from the rubber grommet, but I would like to say do not use them at all (The original supplied type that comes already fitted to the rim).
On the way to the IOW on Saturday I had the valve fail on the front wheel. I was off and me and scoot were sliding down the A3 at 50mph.
Luckily only minor damage to scoot and a some bruising to myself.
I thoroughly checked my scooter the day before and had paid particular attention to the wheels and hubs, especially after seeing the post about the valve failure. At the time they seemed fine and as I had already done about 650 miles on these rims and hadn't even had to top the pressure up I was confident that they were ok.
I was extremely lucky, but somebody wont be so lucky when this happens again. So DONT USE THE ORIGINAL SUPPLIED VALVE!!! Take them out and fit the decent ones as already mentioned in the previous post.
The wheels are ScootRS V3 and I will be e-mailing them to let them know about it and to see what they are going to do about it. (I wont be holding my breath though!)

Glad you're ok mate. I had exactly the same thing happen on the way to Kelso earlier in the year -valve let go on the front V3 rim. Fortunately I stayed on. Contacted scootRS about this but they were about as much use as a chocolate fireguard. Ditched the tubeless rims and gone back to splits. Have a look at the new front rim/disc that Frank Sanderson is selling, ok it costs alot more than a scoot RS rim but having seen one close up the difference in quality between the two is like night and day. I wouldn't touch a scootRS rim with a bargepole :flaming:

Has anyone started using these split tubless rims from Patron racing in Doncaster.Im interested in them and gonna be buying some soon but wondered if anyone else has clocked up any miles on them? At least they are UK based and they seem a decent company who give a s**t unlike some others.

I have run standard split rims with a giant o-ring in-between and a good valve before. It actually does work.

[jimmers]

so what are the suggested replacement good quality valves then?

glad scootrs are contacting there customers again to inform of possible problem
very quiet from them as usual

anymore info on these patron racing rims then please
would love to use a uk based tubeless rim that works with out all the hassle
of the asian crap, and get tyres fitted easy

I've used these for about 3-4000 miles now and haven't found any problems apart from refitting tyres.I've ended up taking them back so that Pat can fit them.

Here's the link for his shop.

I have a set of ScootRS rims due to be fitted on two scooters this winter, one a S1 "rustoration" and the other a GP. Both are touring bikes and I tend to cover a fair few miles each year.

After several posts on this a few weeks ago I checked my rims, which had already been fitted with Schwalbes at a local shop. The compound of the rubber in the valves where it goes through the hole in the rim was incredibly soft and bendy, the valves in several of them were loose and if you just moved them a little they let out air. Not very safe at all, IMO.

Mike (soulsurfer) suggested the Demon Tweeks valves, which are much better. I had them fitted at a motorbike tyre shop - HGB Motorcycles - in Ruislip, north London, just off the A40 and about 3-4 miles down from the M25 turnoff.

The guys there couldn't be more helpful and I would strongly recommend them to anyone in the area. The process involves letting the tyre down, pushing it to one side of the rim, removing the old ScootRS valve and pulling through the Demon Tweeks one.

They charged me £1 plus VAT per tyre (I supplied the valves), because the old bloke who ran the shop used to sell Lambrettas in the 60s and we had a great chat. They may charge a couple of quid more if they realise there's a lot of demand but well worth it for peace of mind. The valves themselves cost about £3.50 each. I suspect it's also a great place to have new tyres fitted on ScootRS rims.

When I spoke to the feller, I suggested to him that he might consider stocking the valves himself, plus a selection of 10" tyres and scooterists would probably travel a fair few miles for excellent and fast service (they sorted six of mine out in 1 hour).

I've also fitted Slime to all my tyres, both tubeless and tubed. Hope this helps.

PS: I am confirmed, if occasionally critical customer of ScootRS. I believe what they do is usually good. But this tyres issue is safety-critical. There have now been three valve failures on tubeless rims to my knowledge and my own valves were not right. I really would like Randall to come on here and tell us that following this spate of reported problems he will, at the very least, be sourcing new and better-quality valves for his rims.

The fellers at the motorcycle shop were also concerned that the valve rubber itself can potentially come into contact with the metal on the rim. Ideally, this is a modification that ScootRS ought to consider on Mk4 rims, if and when they come out.

Good luck with that.

So are these rims definitely tubeless....

It just says alloy, mentions the bead but doesn't say that they're tubeless????
