Workstand Clamping

[youngoldbloke]

I have read that if you have a carbon framed bike with a carbon seatpost you should keep a spare alloy seat post to use when clamping in a workstand. [edit - as User posted above] (I clamp mine using the nose of the saddle). Similar questions arise about carrying carbon bikes on bike carriers on cars.

If only so easy, then I'd need a torque wrench so I don't overtighten the clamp when putting the carbon seat post back in

Did you really?

Over tighten? Nope, I have never adjusted it. But it worries me to adjust it in case I did over tigthen.

Maybe buy a torque wrench time. They are so cheap now.

Yeah just found this:

Seems to get good reviews on Wiggle, although they don't sell it now. Some report issues with "oversized BB", which I am not sure applies to me, somebody specifically says their Z85 fits, although the review being from 2012 it may be an earlier model. Also I ride a 61 frame, the front wheel may go beyond that guide!

I had one of these, ok for a traditional BB but doesn't work for oversized ones..they won't fit in the bracket/holder..unless the design has now been updated.

The reviews on wiggle, which are old, suggest the same thing. I am not sure I have an oversized one, but it doesn't future proof it much I guess even if not.

I got a torque wrench a month or so back. Best tool ever bought tbh. Really takes the guesswork out of things and not as expensive as in the past either.

People will come along and say it's not required as they can "feel" the right torque without a torque wrench. Good luck to those with that unique skill, but a torque wrench is my preference.

Hmmm...how tight are people clamping the top tube? Surely just enough to hold the bike securely, not sufficient to dent or crush the top tube. I have steel, carbon and aluminium bikes, and have had no problems with any. I was only thinking about protecting the paintwork, hence the foam or rag/towel comment.

If you have a workstand where the clamp assembly rotates you can reduce force on the seatpost by putting something under the front wheel to take the load before locking the clamp assembly.

Don't they need calibrating? How would you go about this.

Is a good thing:

They come pre-calibrated.

I use one of these: http://www.amazon.co.uk/gp/product/B00FPRITUQ?psc=1&redirect=true&ref_=oh_aui_detailpage_o06_s00 Similar in concept to the one BrynCP mentions. Works great for the Tesco special but the wife's Caprice is too curvy. There's a hook that clamps the down tube. If your BB has a good triangular shape it should work.
