No more pain on the trainer

Just a bit of hope for those that experience pain on the trainer and don’t think a bike fit will fix it.

My trainer bike is a TCR; so quite stiff. I couldn’t go 30mins without pain.

I lowered my saddle because I assessed it was too high.

2hrs on the trainer absolutely pain free - quite a hard saddle.

Bit of tilt reduces numbness.

Look in to a bike fit if you’re experiencing this issue because it can be fixed :+1:


out of curiosity. Are you using the Giant stock saddle that came with the TCR?

True, most people have their saddles too high. Then again, just took my bike off the trainer into the real world this week and had to raise the seat. Best solution if you can afford it — 1 trainer bike+fit, 1 outside bike+fit.

Good catch! That’s a big difference.

A fixed trainer is less forgiving of those marginal setup issues. You might be able to move around and adjust outdoors but not on the trainer. If you have a super stiff bike, though, once you get the fit correct it will be more comfortable on the trainer than it is outside.

I’ve got an NK1K & it can ride a bit harsh outside but it’s actually pretty comfortable on the trainer.

It’s funny, I’ve found the reverse is also true. My trainer bike is really stiff and went out of commission for a bit, so I substituted in my Canyon Endurace for a week and had terrible saddle sores. My opinion was that all the frame flex was translated directly into the saddle which acted like a windshield wiper on my hind bits. Ouch.

Not sure I understand why the seat needs to be different inside vs outside. For me its the same bike. Bike fit works on angles etc.

I can understand if the bike slowly dropped height over the winter but otherwise I would not expect a difference.

It doesn’t. Being on the trainer is less forgiving so incorrect seat height is a more obvious issue indoors.

I use only one fit as well. However, if you use different shoes, be cognizant of the stack height.

Too low a saddle can cause pain as well.

No, I’m using Selle Italia SLR Superflow (titanium rails).

That’s interesting - I was considering getting a more flexible bike to deal with the issue as well at one point. Glad I didn’t now!

Good point and this is probably why it seems easier to pick up on fit issues indoors.

Also, some trainers are not level, i.e. my elite novo force has a discrepancy with how high each wheel is of the ground. The back wheel is not at the same height as the front one with the stock front wheel holder in place. Obviously a design flaw. What it does is it tilts the entire bike so you need to correct that with your saddle height and tilt. Once you go outside you then need to change the whole thing again… Bit of a pain in the ass :see_no_evil:

I had forgotten about this! I’ve been having knee issues on the trainer on one side maybe this could have something to do with it!

Haven’t ridden on the trainer for a year or two and it’s pretty symptom free - but the trainer is killing me.

Actually I see you mean not level front to back… I mean not level i.e. tilted to the left

It can actually be tilted in any way. If the trainer doesn’t have flaws like mine you need to make sure that the surface on which the trainer stands is level. If you are having one side knee problems then it potentially could be due to the trainer not being level left to right.
