TIA, Spider I don't know -- I own two aluminum bikes (one racing, one mountain) and I've always clamped them in the workstand. I'd rather clamp an aluminum tube than a carbon fiber seatpost. -- Bob M in CT Remove 'x.' to reply |

I wrap a shop rag around my seatposts (regardless of type) before clamping in stand. I also let the saddle and front wheel take most of the bike's weight, as usually I only need the rear wheel/drivetrain elevated to work on stuff.

Just make sure that the jaws of the clamp don't have any pieces of dirt, metal, etc. stuck in them. The relatively soft jaws and large clamping area don't pose a problem for a carbon seatpost. The force applied to the post by the seat tube clamp on your bike is far greater than a workstand bike clamp. I used to clamp my carbon post all the time. Having said all of that.....I don't like carbon posts. I've never seen one break, but I also never want to see that. |

Some frames (like mine for example) have inserts in the top of the seat tube. The seat post will only make contact with the frame for the length of these inserts - and they're not all that long (don't have to be). Heh - that's why I specifically enquired: 'What's wrong with clamping around the top of....' ',;~}~ Habaneros have 7cm inserts - long enough to beef up the top tube/seat tube/seat stay junction, and more than long enough to handle the seat post. Of course, I also don't worry about clamping my frames in ANY workstand. As BTO woulda said (about a million years ago), they're "not fragile". Spammer! ',;~P~ I wouldn't be the slightest bit concerned about clamping my (alu) frame by any part of it either - it's certainly tough. Shaun aRe |
