Gp4000s on rollers...hol s@£t

boogi11

So I've been using my rollers with a set of Vitoria tyres for about 4 months, and really thought I was the kiddy, no hands, drinking from the water bottle etc.......put on a new set of 4000s. It's like somebody took the stabilisers off, I'm all over the place , I hope these tyres are this slick on the road

Rollers are a really good way of wearing out your expensive tyres. Get some cheap hard tyres instead.

boogi11

But that's why I bought rollers in the first place, so that I did not have to fanny about swapping wheels over .
Surely a tyre as good as the conti should wear well on rollers

desweller

It takes 5 minutes to change a tyre.

There's no airflow and you're running on the same surface over and over. The roller gets hot and the tyre overheats; it's not designed for that use. It's like being surprised that a race tyre doesn't last for 20, 000 miles.

They are great on the road though.

love my gp4000s, but you really should invest in a proper turbo trainer tyre, its not that hard to change over, and even if it does become a pain then get a cheap rear wheel to swap over.

no need to change tyres for rollers like it is for a turbo

This, rollers are probably less wearing than road.

Totally agree, no het build up at all, on tyre or rollers, I think people area getting confused with turbos

Yes sorry I thought they were the same thing :oops:

Weird. Are the rollers metal or plastic?

What is the general approach here, do people run an old tyre on an old wheel or go to the bother of swapping tyres over? I have just switched from old cheapy utrasports to gp4000s (was hoping my ultra's would get me through the winter) and have been avoiding the turbo for this reason.

I take it the GP would die after a few 100k if it was on a turbo for long?

desweller

Fair enough. Seems like an odd use for a premium tyre to me though.

Old wheel with a TT specific tyre on - Just use old tyres though if you have some until they give up, then get a TT specifc one.

Throws the shifting out something terrible mind...

boogi11

the rollers are plastic, but please note this is a roller not a turbo, the back wheel is free to move across the roller as you pedal, and this was the point of the thread, with the new tyres, its so much slicker than the old ones, but as mentioned , their is no heat build up at all.

I use GP4000's on Elite rollers,found them a bit sketchy at first but you will get used to them.
They have suffered no wear at all from the rollers,and are the best all round tyre I've ever used !

mamba80

pump them up 10 or 15psi higher than for the road.
the high spec tire has a softer side wall and the load is slightly greater against the curved roller.
im about 77kg and use anything from gp4s to pro3, vitt pave (or even Zaffiro slick) and have no problems with about 110 psi f & R

Had a bit of a moment the other night when the Buff I was using to wipe sweat from my face fell off the handlebar and into the front wheel....I nearly soiled myself !! :oops:

boogi11

lol.......i keep draping my towel over the chip in the very expensive sideboard i created the other day when i smacked it with my bike stand.
apprently turning our newly decorated dinning room into a training /repair shop is not ok and will have sto stop

Supposedly new tyres sometimes have a mould release agent on them which can make them a bit slippery for the first few miles. Could be that...

(Or that could be an urban myth.)

It's true, Go for a ride on a set of Vittoria open corsa cx in the wet without scrubbing them in first...... It's like riding on ice. As soon as that fine layer is scrubbed off they're fine.

logitech208

I run GP4000s on the rollers and have no problems with them at all, I would imagine it's because they are new and need scrubbing in a bit, also Rollers wont wear your tyres out.

I do run higher pressures on the rollers compared to the road.

cougie

Ride them round the road for a bit - that should dirty them up enough ?

Not allowed on a wooden track unless tires are wipped down with white vinegar and sanded down + a few laps on the concrete first, and no dual/tri compound tires either.

Hang on sec though, I put my bike onto my turbo and ride for an hour or so when the weather's shite and when the weather's a bit better I take said bike off the turbo and ride on the road without so much as tyre change. Now given the advice given so far, does this mean I'm going have a rear tyre explosion and crash and die horribly?
I would like to remind some of the posters here that not all have either the time or money to keep changing rear tyres or wheels.

Yes. You will die....not.

All a turbo will do is wear your tyre down more than it would on the road. You can buy a specific tyre which is a bit harder than a normal road tyre so it wears down less quickly and it's 'meant' to make the turbo experience a bit quieter – or you can use the tyre that’s on your bike. The choice is yours. I just happen to have a spare rear wheel/cassette and a bunch of old tyres that I'm working my way through.

Specifically t Turbo will square off a tyre - so instead of having a smooth round surface it will be flat in the middle with "shoulders" at the side - a bit like and MTB tyre - This makes cornering feel...unusual...

Yellow Peril

Anyone using a regular tyre on a turbo will probably have noticed the "skidmark" left on the turbo roller, that's your tyre wearing away. I had a Panaracer Pasela completely delaminate on a turbo a few years back.

I use a turbo specific Vittoria now. It's bright red because just as regular tyres shouldn't be used on a turbo, turbo tyres shouldn't be used on the road :twisted:

pinno

I bought a set of rollers and had such a hard time staying on I bought one of these:



Now I am confused, except for the fact that my tyres are an old set of Michelin Pro 3's which are pretty worn anyway.
Just wondering if a set of roller tyres would mean I could get back into the hotseat again and take the T bar off....hmmm.

Still, even with the T bar tons better than my old turbo trainer which was a torture device from hell.

Monty Dog

Tyres get warm on rollers, but not hot IME - turbos are far tougher on tyres, hence specific tyres. I use old road tyres on both - never cooked one.

I know that happens with car racing tyres so maybe its the same.
