My bum hurts - please help!

[mick1836]

I've been riding nearly four years and I'm only just now finding out how to sit on bikes properly. I think I need another two months and I'll have it right.

I think you get it quicker if you ride or socialise with experienced riders. The whole sit bone thing was a slow revelation to me.

Tin Pot, are you saying that you now no longer get any pain or discomfort from your derriere region no matter how far you have ridden? After 20+ miles I'm sure my saddle looks like this?

Coincidentally I just read about this boingy springy thing that has just raised some money on kickstarter

I know how much people on here like to scoff at "new" ideas, so, on my mark, scoffing at boingy thing, in three, two, one ...

On my roadie, not really no. I'm anchored on my sit bones throughout, out of the saddle every 30 minutes for 30 seconds and occasionally roll my hips forward onto the soft tissue if I'm into the wind. No lower back trouble either by the way...last ride was 4.5hrs.

I was severely knackered but not in pain.

I'm now going through the learning curve for TT saddles and aero position...this, this hurts.

The TT Aero positions on a bike must hurt your Perineum..........


This is a good read:

Especially the info on "What about triathlon and time trial?"

"With a forward-rotated pelvis, the sit bones are typically off the saddle surface, and the weight is borne in various degrees by the pubic bone, inferior pubic rami and the surrounding tissues. The choice, then, is where to apply pressure?"

Many bike shops have “assometers.”

No, actually.

ISM saddles have two stubby prongs so the perineum doesn't come into it. It's a weird sensation that feels like it should be painful, but oddly doesn't really hurt...at least not like resting on the perineum does.

It feels like it is holding the sit bones but from a different angle, putting pressure on places you probably don't feel very often.

Also I've set up the bike according to my fit measurements but it needs some fine tuning by my fitter on the 19th. Too much weight on my biceps for a start.

Ah, yes the ISM Adamo.

"Pick both sides: This is the ISM Adamo approach. The athlete sits on the two noses of the saddle, with the left and right inferior pubic rami resting on the left and right saddle noses, respectively. This works best when the athlete’s only contact is truly on the tip of the saddle, with most soft tissue off the front of the saddle. Pressure is on only the first few centimeters of the saddle’s noses, with virtually no other saddle contact. (This means for any constant body position, an ISM Adamo saddle should be installed 5 to 7 centimeters farther back.) For many riders, picking both sides may be the best of all possible worlds for the aero position."
