Workstand

Postby alan winstanley » Wed Feb 27, 2013 12:59 pm

Hi,
Why is the preferred method clamping by the seat post rather than the top tube ??

Seat post every time for me - and many also reccomend getting a cheap aluminium seat post if you have a carbon fibre one.

In most cases (I would actually suspect/expect it may actually be in all cases) the seat post will be a lot less likely to be damaged (thin walled light weight tubes etc) by a clamp that tt.

If you're really concerned, you can use one that clamps the dropout, with the bike resting on the BB shell. I bought the Elite version, there's a good (albeit pricey one) from Park Tools also.

My one (price seems to have risen quite a bit since I got mine. There's a Tacx one at the same price that looks to have a few nice add-ons)

the seat post is designed to be clamped. the frame tubes are not.

Thanks Guys, but why ?. I've been doing the top tube since I got it with no probs. Is the top tube really that delicate ?

Seatpost designed to be clamped ? really, how ?

cheers

Your seat clamp clamps the seat post - it's strong in that direction.

The top tube isn't designed to take a lot of force in that direction, more for lengthways from head tube to seat tube - depending how exotic a frame you've got, the wall thickness can be scarily thin, particularly triple butted tubes etc. Clamp too tight and it'll fold in on itself.

Seat post, ie the thing your saddle is attached to, not seat tube. There's a difference. The seat post is designed to be clamped in order to keep it in position.
My alu frame has some very thin walled tubes in places so I'm very careful when using the workstand.
