Wearing out bib shorts

Postby briztoon » Sun Apr 29, 2012 7:08 pm

OK, simply I don't know who to ask about this. So the anonymity of the forum has to do. And I don't really feel like taking a pair of my bib shorts in to a LBS to ask the guys there.

I keep wearing out my bib shorts at the top of my left thigh at the edge of chamois padding and stitching. It's got me stumped/pissed at how fast I am wearing a hole in my bib shorts (3 months). The area where the holes keep appearing is a little forward and below the area of padding that I sit on, so don't rub anywhere near as much as main padding area. And the left side wears through much faster than the right side, though there are signs of wear on the right side as well.

I'm trying to work out how I am wearing this section of my bib shorts out, and wondering is ok to stitch extra material over this area?

Exposed stitching on your saddle?
Perhaps you have a saddle bag with a Velcro wrap around the seat post... The exposed Velcro grip can tear at the material.

The only time I have had that type of problem was due to a saddle where the branding was raised stitching.

It has to be caused by a rough area on the saddle as I can’t see any other valid reason for wearing the same spot every time, unless of course you have been eating to much concrete and one of the family jewels is now a lump of rock. :lol:

i to have this issue of abnormal wear in one specific spot similarrto the op and look forward to any comments!

was thinking maybe that i don't sit perfectly symmetrical on the saddle, perhaps due to a leg length discrepancy?? just clutching at straws!

I'd rather pat Mr Humphries any day than that user name. :shock:

Apologies for the unhelpful information.

Is the saddle correctly aligned over the centre of the top tube? It might be a little off center. Try this: Sit on the saddle. Bring your right pedal to 12 O'clock. Push your right knee firmly into the top tube. Remember any pressure there might be on the inside of your right thigh. Do the same with your left pedal / left leg. If you feel any difference in the contact pressure on either side, it could be the source of the problem.

Large thighs and the material of the knicks is bunching up right at the edge of the padding, and rubbing on the bottom edge of the saddle?

A soft lambswool cover over the saddle is nice to ride on. :wink:

I had this happen once. I had recently got a narrower saddle and without noticing it my thigh was rubbing against where the saddle is held by the post clamp. LBS gave the clamp a light file and fixed the problem.

:shock: The mind boggles.

I've had the issue that Kenzo mentioned. A saddle bag with a strap that wraps around the seat pillar. It only takes a few of the 'hooks' from the velcro to tear into the knicks.

In placing my saddle further back, it has caused the clamp to be exposed to my legs which inturn A) Wears out my knicks where they brush the clamp and B) Wears the black finish off the clamp. I hadn't noticed it while riding it was solely when i went to re-adjust my saddle.

Thanks for all the ideas guys. It turns out that the velcro strap from my saddle bag was the cause. It had curled back a bit and every time I sat a little further back on the saddle, it would rub on my bib shorts. Quick solution, a pair of scissors.

after going ages and ages without any issues at all with my knicks, i've had 3 pairs of shorts die on me in the last couple of weeks.

this thread has given me a few ideas for a potential remedy though

thanks all :thumbsup:

Does that mean someone can figure out how mine wear on the front left hip then?!

so my friendly LBS guy suggested that perhaps over time my seat might have slipped backwards a bit, enough so that my knicks rub against the clamp of my seatpost.

so i've moved my seat forward a touch, so far so good.

I seem to have this exact problem as well, found a hole in my 3 week old knicks this morning. :x :x
My seat is perfectly smooth and not hitting the saddle bag hmm.

My gut feeling is material bunching up and then being ground into the seat because I don't think there's anything it could rub against.

Quite often it's the saddle clamp, or a fixture to the seat post (ie saddle bag, Velcro, tail light bracket etc) that is the hole making cause. If your using a saddle with carbon braided rails, the abrasive tape to reduce saddle slip on the rails can be a source as well.

A much slower cause is sitting asymmetry on the saddle. As alluded to earlier, this is often from unknown or Uncorrected leg length discrepancies, or poor cleat positioning, amongst several others...

Rough or sharp plastic underside of the jersey zip?
