Anybody an LCGB member that can read the link that 'Warning new generation tubeless' goes to and let us know what it says? I can read the forum but not being a member cant view the link.

Initially started in response to the accident thread....

On the subject of blow-outs, one I have first-hand experience of, I was SHOCKED to find a bloke on Kite Hill having to put his spare standard rim on in place of his new generation alloy tubeless as a result of losing 3 of his rim to hub nuts, with the other working its way loose! The movement had caused the rim holes to oval and had effectively written off the rim. His RB20 is not the sort of scoot you want to have high speed wheel issues on (not that any scooter is!).

It appears that the standard hub studs were not long enough to allow the nut to seat fully home on, certainly not getting to the nyloc element, and this had allowed them to work loose. For this very reason SIP supply longer than standard studs with all of the rims that they send out, which is a pain in the *** to change but at least they are acknowledging the potential issue. It appears as though the rider in question had not been supplied longer studs when buying the rims and had not been given instruction to address the issue. I cannot confirm which dealer supplied the rims so cannot suggest that anyone in particular is at fault but it is an issue that ALL people need to be aware of, especially if they are looking to IMPROVE rider safety

Ride safe all.

i would assume longer studs mean sip ...but if he did not fit long studs i dont think he would get the nuts on ...so i should perhaps assume these are af type , this may be then an issue with user error

I can't see how the rims could be SIP because if you try to fit a SIP rim on normal studs you can't get the nuts on as there's no thread showing for the nut to grip.


My bit
I agree with martin, i bought 3 rims with tyres fitted from him and the all came with a stud kit each and two sets of nuts for each rim.
I have read elsewhere some people weren't checking the nuts were on correctly but martin sends out all the bumf so you cant go wrong, or in my case my man can't.

I don't do dirty manual work

Agreed, sounds like user error to me

[RICSPEED]

is would also seem he fitted normal nylocs not the special ones that should come with

If you were to fit the excellent SIP rims to standard studs you would do well to find much thread at all. All the problems I have been told about involve the rims sold in Yorkshire.
