Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

tire slipping on trainer - help

Of course, with the return of good weather, who wants to ride a trainer?

But at least once a week, I do a trainer ride and often these include short sprint efforts. What's chapping my buns is that if I punch it going from low effort to high, the rear tire slips. Anyone else have this problem? Anyway to fix/deal with?

As for equipment, its Vittorio Rubino tires, pumped to 105psi and a Kurt Kinetic road machine with the tension knob turned 3 full turns from point of contact with tire.

As for engine, we're definitely not talking about Tom Boonen here. If I can make the tires slip, I can only imagine what other folks must have to content with.

my slips quite frequently. you just have to smoothly work your way into peddling harder. i have just learned to live with this problem. if anyone else has a suggestion like adjustments or what not i would love to hear it as well.

I ride with less pressure in the trainer tire to get a little more rolling resistance. I also use Bontrager Select tires on the trainer. CycleOps Fluid 2 cam lever turned 180deg past contact with tire, then locked down. Nice and snug, and a good workout.

my Blackburn fluid trainer does that too. Sometimes it's because my set screw is slowly unscrewing; making the contact between my tire and roller father apart. That might be happening to you, but I'm not sure. I fixed it by putting a nut on the other side of the set screw to "lock" it in place

Tough nuggets, really. Going from slow to high effort, the tire will slip.

I wipe off the tire (I have Rubino Pros too) with Windex. I also wipe off the roller to get any crud or grease off. It seems to help quite a bit. The tire still slips, but I have to crank much harder compared to a dirty tire.

+1

Clean tire and roller helps allot. My 1 Up USA can really crank the tire down hard on the roller as well. Plus, I use a trainer specific tire from Conti so I don't mind tightening it down hard since that tire hardly wears at all.

I will try the Windex / cleaning method and let you know how it works.

Thanks all.

Crank the tension up a bit and you won't slip anymore. Dirty tire or not.

this will strain the wheel bearing and the trainer bearing.

A lot of the slip is from the road tire rubber over heating and sloughing off. If you are seriously using your trainer, road tires are not for this, you need to use the orange trainer-specific tire from continental.
Mine is going on two seasons and does not slip at all, with two turns of tension, even during out-of-saddle drills. In the long run, it will save you money.

I would ever recommend putting enough tension on to cause any of that strain. While not having used a Kurt - most of the other trainers that I would use I could turn about 1/8 - 1/4 of a turn more to eliminate bad slipping.

Tire choice is key though. I use the cheapest tires I can find. Mine tend to heat up quickly and then any slipping usually stops.

Turning the tension up a notch is going to put more strain on the wheel bearings than the weight of your butt pushing down on the road? Seems unlikely that the stress the wheel bearings get on the trainer, where the wheel is not supporting the weight of the bike and rider, is higher than the bearings see riding on the road.

Or a cheapo tire for this purpose. Actually melted the surface of a TriComp using it on a trainer.

Cheapo Chinese tyre. Works great, does not wear out. It's only a problem if you keep moving the bike from trainer to road - you don't want that 3-ton piece of solid rubber on the road.

I tried the cheap tire approach, cheap tires are harder, but I can burn out a Rubino in 1 1/2 hours. Once the temp gets up and you start doing 130-140 rpm spinning drills, any road tires will shred. The contis are $40, and last forever.
In the long run, it saves money and doesn't leave the rubber dust behind.

But the trainer bearing is not designed for that, it's in the manuals.
Also, the wheel is fixed and all forces are beared by the hub only, not distributed throughout the frame as on the road.

Performance always seems to have their Forte Titan on sale for around $80.
