I have the Pedro's Folding Repair Stand
which I bought a long time ago for my Klein mountain bike, but now would like to use with my Brompton. I wonder however how I should clamp the Brompton in it.
On the Brompton website I found a video in which is adviced against securing the bike to the seatpost. However they are not very clear about the reason behind that. I always thought that it was better to use the seatpost, because that way the frame cannot be damaged. Moreover with my Brompton and the Pedro's stand I noticed that, when clamping to the frame tube, I have to do it near the main hinge because otherwise I cannot turn the cranks. And I have to be careful with the cables.
When clamping to the seatpost I don't have this problems and it is easier to lift the bike high enough.
1) Does anyone know why Brompton advices against using the seatpost ?
2) Would it still be safe to clamp to the seatpost and if so, then near the saddle or near the seat tube ? And would it be better then to lower the seatpost as much as possible ?
