Preventing Slippage on Turbo

Hurricane151Hurricane151 Posts: 632
I have a Tacx Booster Turbo and I have a bit of set up issue. When I have the resistance set high with lower cadence my tyre seems to slip at certain points of the rotation. I have the following

Standard Tyre (conti 4 season)
Tyre at 120psi
Resistance roller as tight as possible on the tyre
Q rings (not sure if it is pedal stroke related

I am looking at possible reasons why I can't get a smooth pedal rotation at higher resistance. At lower power and resistance there doesn't seem to be any issue and the pedal action seems and feels fine.

I am looking to more TT related training and want to use higher resistance but at the moment it's just not possible.
any help appreciated.

    make sure the roller and tyre are free of any grease, dirt etc.

    use a trainer-specific tyre (ideally get a cheap wheel to go with it), these have a compound designed to work better on trainers, i use a conti tyre, there's no slippage even over 1kw

    some turbos give irregular resistance until they've warmed up, i remember using someone else's and it took ages before it was smooth

    Its a mistake to put more pressure between the roller and tyre to over come slipping. It must be as light as possible to do the job. So a well cleaned tyre is essencial.

    If you want to be a strong rider you have to do strong things.
    However if you train like a cart horse you'll race like one.

    Have you tried pedaling less hard?

    I have had the slippage thing also so now I always start with a low resistance setting then once up to a good cadence move to more resistance and up the cadence, this seems to work on my turbo.

    This would work but would kind of defeat the purpose.

    I'll give this a shot. I always do it to a point where the tyre is quite depressed against the roller

    IME an indoor turbo tyre gets rid of 99% of slippage issues - night and day compared to a road tyre.
