I've got some new wheels that came with tubs. I need to buy a spare tub for my Ironman and was wondering what the main advice is when changing it:

1) Remove punctured tub, tape the rim, fit the new tub
2) Pre tape new tub. Remove old tub. Fit the pre-taped tub. Remove backing.
3) Pre glue new tub. Remove old tub. Fit new tub
4) Something else

Any help very much appreciated.

put new tub on old wheel for a while so that it is pre stretched...it will make life a lot easier when you come to fit it once glued....

Cheers for the pre-stretch tip. What about actual fitment of a new tyre in the race? Glue, tape, nothing?

fit tub using tape. leave for a few days, remove and roll up. dont worry about losing sticky, it wont be enough to worry about. In race rip old tub off, there will be residual sticky left on rim. new tub on. the older tape and residual sticky will bond and with the air pressure make a good enough connection to finish the race. Just dont go descending at 60mph into sharp corners.

Cheers hammerer,

I don't have a spare wheel to fit the spare tub to, so should I just tape the tyre and leave for a few days before rolling up? Should I leave the backing tape on or take off?

cheers

put it on your wheel after your last ride before a rest day and take it off before your next ride.....put the other back on....or swap over so that you have a well stretched tub as your spare...

backing tape off. I do what eJC says just when i get it i put it on for a bit and then take it off and put other tub back on. I normally re tape my tubs regularly anyway (i dont use race wheels much anyway so after prolonged sitting around in garage)

Fellas....
Joe Duckworth ... limitless tri seems to be going well....
Not sure how long he's been coaching?

He will obviously be a back of pack stalwart in two years.

He's just placed high in a local sprint... in the middle of IM training.
I always thought you'd go faster being a full time athlete...
I guess other people get in the way.. who your trying to make faster...

As long as you enjoy it hey ho!

None of us going to the Olympics... unless your watching.

depends what hes doing coaching wise. Is he just dishing out training plans over the internet or is he poolside most days after planning the training cycles and sessions? I very much doubt he'll be competitive for long doing the latter
