Doing some bike cleaning today, one thing I made sure to do was to pull off any threads that my conti tires have been shedding. The threads come off just above where the tire meets the rim, and when pulling on them, it usually pulls off on around the rest of the tire, so each thread can be that long. Besides coming off the tires (I usually notice and pull them off), some of it was wrapped around the front hub, and there was even a little in the rear derailleur. Yuk.

I've used these tires for quite a while, and may have gotten a couple "unique" ones or something. It doesn't seem to otherwise affect durability/longevity. Indoor parking, so it's not a sun thing.

Is this a known conti issue?

Happens all the time to mine. The rubber's also started cracking, but don't think it has any effect on the integrity of the tyre.*

Don't mean to hijack this thread but kind of related... An a**hole taxi driver cut me off this morning to pick up a fare so I had to go into a skid to avoid smashing into the cab. When I got home I noted that the skid had scraped away about 3cm of tread of my rear 4000s and the cotton under the rubber is now showing. Are these tubulars done?

I use Gatorskins but rarely have this issue. I used to ride on 4000s before, but thread shedding was rare too. Even if I find a loose end, I pull it off carefully and won't happen again. Maybe I'm just lucky.

Some 20 years ago I used to have this issue on my MTB tyres (Panaracer Timbuk-II) very, very often.
