strange wear and tear on bibs

I've been riding a Selle Italia SLR saddle for over a year and recently got a bike fit. I've just noticed that since the fit my bibs have are getting worn out in this one spot. have any of you ever had this issue? bibs not worn before fit do not have this issue and all after fit have it.

Thanks.

Same saddle here, same type of wear after 3000-4000 miles. I don't know if that's normal or not.

Saddle bag with a bit of the velcro strap in the wrong place?

Selle Italia SLK saddle for me. Same wear in roughly the same place. I've been trying to figure out why, since all of my bibs and tights are worn in the same spot. I've been fitted on my bike - the setup is perfect and I have no discomfort. I don't have a saddle bag, so that rules out.

My best guess at this point is that my right leg is probably a little stronger than my left, so when I am going hard, I must be subconsciously shifting my position just enough to cause extra friction there.

Looks like it's on underside of chamois, that wouldn't expect that to be seatbag. Seatbag rubbing is lower down on leg, high or mid thigh.

I'd suspect edge of saddle. Never had that issue with my toupe, but then everyone is quite a bit different.

Some saddle's have logo stitching up on front side of nose. Rubbing?

Definitely not the saddle bag because I dont use one. Went back to the bike fitter and he said i can try a slightly wider seat since i'm in between sizes. So, he is letting me try Fizik Antares. I have a Thompson masterpice seatpost and the fitter said he could not see it rubbing with it at all. So, I'll try this new saddle and see. Thanks all for you replies.

Is it something that you might be catching when you are not in the saddle? Perhaps something on the top tube that you touch when you are standing over the bike, but not on the pedals?

My top tube looks pretty clean and i have nothing on it. But I guess its possible that i'm unknowingly rubbing the tip of saddle when i stand up on pedals. I'll have to pay attention to that just in case. thx.

Make sure you don't have a lopsided testicle.

Methinks you are dropping your right hip when pedaling. That would account for the asymmetric wear.

It's not the saddle. Not exactly...

I have the SLR Kit Carbonio Flow and never had this problem. My Saddle was pushed all the way forward on the seatpost originally and after adjusting my fit through the year it ended up being push as far back as it could go on my 3T Doric seatpost. Because of this, the seatpost clamp now sits right below the narrowest parts of the saddle and extends out further then the sides of the saddle. This now causes the same wear you mentioned in the exact same place and only started happening after the seat adjustment. It didn't happen before because the clamp was sitting under the wider part (the rear) of the saddle.

Here is an example of the problem that I'm having and others on the Cervelo forum are too having: https://forums.cervelo.com/forums/t/7641.aspx

This does sound like it could be it. What did you do? Maybe the wider Antares saddle will help.

I wasn't the original poster on that thread. He was having the rubbing problem with his Antares saddle cause as you can see in one of the pictures the seatpost clamp extended further out from the sides. I'm having the same problem with the Doric seatpost and SLR saddle combo. Since I have the LTD version (yoke is made of carbon) I couldn't nor wanted to make a mod to my seatpost clamp so I just put some electrical tape over the sharp points on the clamp that my bibs could rub on and seems to work so far. We'll see down the road. I suspect that this occurs often given certain saddle and seatpost combinations.

I get that wear on my Assos FI.Mille and club bibs using an Antares and FSA K-Force Light. I don't see the clamp extending beyond the Antares sides so it must be leg fat...I mean muscle. It's not catastrophic wear and I budget getting a bib or two a year so I'm not concerned. GL

When you had the bike fitting, they also measured to make sure the saddle's the correct size, right?

The bike may fit but do you? I say you sit asymmetrically with your new position.

The fit was done by a professiaonal bike fitter (Specialized BG fit) and it took about 3 hours. I was in between saddle sizes and since I already had the SLR i decided to stay with it at the time. The fitter could see no rubbing but that was in the trainer, i'm sure it's must be different while actually riding and probably same with symmetry.

Uh huh. Thomson Masterpiece. I have the same problem. My shorts were dying early deaths due to holes worn just where the seatpost clamps the rails. I solved it by covering the entire clamp area with some electrical tape, which stopped the wear on my shorts. Later on I found a more permanent/elegant solution by molding a little bit of thin kydex (heat-molded plastic sheeting) over that area. I can post pics at some point.

Please do! I to am using electrical tape as a temporary/immediate fix.

Ok, finally got around to taking some pics. I basically took two rectangles of very thin (.06) kydex and heat-molded them around the clamp and rail area. I did it shiny-side out because the other side (at least the kydex that I had) has a rough texture. The final prodcut looks like:



The reason they are better than electrical tape is...well first, they look better. Also, they leave no sticky residue, and they snap on and off easily. Here you can see them off the saddle:

Outside:


Inside (kind of tough to see):


Oh, and one other thing I learned from dealing with this problem of premature bike-short death was that you could fix the shorts if you caught the problem early. If you see wear in this area, before it wears all the way through, take some of this stuff:



Seam Grip, and put a few drops on the spot and spread it into the cloth with a plastic card (Costco membership card works great) like you would spackle a hole in a wall. It will dry and form a kind of "scab" that will prevent further wear and unravelling of the cloth. Careful with how much you use; too much and it will goop up the inside of the shorts and chafe badly.
