Okay, I'm still trying to find shorts that get the job done without big problems.
I recently read about it being important for the leg of the shorts to stay down to avoid bunching. I was having LOTS of irritation where my leg meets the torso, though I didn't actually think it was "bunchnig". So, I made it a point to pull the leg down at every stoplight. This helped a lot, though sometimes I didn't hit many lights so it wasn't perfect. You see, I have not found any shorts - not even ones that are clearly too small for me, that has the hem of the leg tight enough to stay against the leg. There is ALWAYS a gap someplace - so grippers aren't a real solution since there isn't full contact.
Now, besides the irritation at the torso/leg contact point, I also get irritation two other places and it seems to be pretty much the same thing. The 2nd worse spot is the scrotum. It feels like the padding is causing irritation. Not quite as bad (usually) is the same feeling on the butt.
In the last couple weeks, I have made various changes:
1. Dropped the nose of the seat a bit below parallel. That helped with the scrotum (but not always - today was bad). It doesn't seem to cause any other problem though. For example, I don't feel like I'm sliding forward.
2. I slid the seat forward, eventually as far is it would go. This may sound stupid, but I was apparently not sitting on the sit bones. Apparently when getting fitted, I did, but in normal riding, I tended to want to be more forward. Now that I am on my sit bones, that MAY be causing some of the soreness on my butt simply because I'm not adjusted to the pressure there. Sometimes it isn't a big deal (I ride about 19 miles, rest for several hours, ride back home 13 miles. The entire time, I'm wearing my bike shorts.
I have also tried two different kind of padded underwear, advertised as turning any pair of shorts into bike shorts. One pair looks similar to bike shorts (has legs - which have a gap at the hem like my other shorts) and the other look similar to jockey shorts. I've had a fair amount of success with the jockey shorts style. I can often avoid the problem of irritation at the torso/leg point (though not always). But the other two problems vary. Some days I get one or the other, or both like today. Occasionally, on my length ride, I have minimal problems.
So, after that long lead-in, I have two basic questions to start:
1. Is there a possible solution to the problem of finding shorts that hold snugly at the hem? I'm not sure, but apparently my upper leg is a bit shorter than the norm and thus the hem is further down on me (thus a narrower part of the leg) than others. I even tried triathlon shorts to deal with this, but while better, they don't do the job. I need to find shorts that taper more than most.
2. To deal with the other problems, it seems a different pad may be good. Are there any that are less coarse than others? They all seem soft enough to the tough, but wearing over time is a different thing.
Also, has anyone else tried the padded underwear? I'd be interested in different kinds. For one thing, they are a lot easier to deal with.
