  1. I know this my seem a basic question, but...
    I have a carbon seat post. Today, while cleaning my bike up...I noticed that there was a "hair" right near the clamp. Anyway, upon further inspection...I found it to be cracked. 🙁 I don't know how long this has been there, though I normally notice small little things like this. Anyway...
    Is it "ok" to still ride on it (untill I can get it replaced)??? Or should the bike be put up, 'till I can get a new seat post?
    About the only other detail that may be of some help...is that the "crack" is about a 1/4 inch long, vertical, and right in the clamp area. I think the clamp actually cracked it...from what I can see.
    Anyway...thanks for any help and advice!!!

    Imagine what it would be like for the post to break and your butt to come down on shards of the seat post, taking a core sample of your scrotum. :eek: If you can live with that possibility then go ahead and ride it.

    I dented a CSP with the split in the seat tube by over tightening the clamp on an al framed bike. I've since spun the clamp around 180 deg as is recommended by specialized.
    I did repair the post by inserting an al tube around 50mm long in the area of clamping. I chamfered the ends of the insert to allow it to go past & push out the dent. Now done 8k ks without mishap touch wood.
