I have been using the Pletscher ESGE multi-zoom prop stand (typical price £21 inc p&p) on my Galaxy 531 tourer for a couple of years now.
Some Observations:
1. It gives good stability when loaded but I have had one snap whilst carry about 12-15kg luggage
2. It fits on the back end of the chain-stay with a stabilizing arm attached to the seat stay with the prop leg extending rearwards. Two points to note:
a. The stand has indented the chain-stay tube, not to a level that causes concern, but this does bear testimony to other poster's observations of tube crushing
b. If you have big feet (I'm size UK11), watch out for heel clearance.
3. I note from the SJS site listing that a max weight of 18Kg (bike plus luggage) is quoted
http://www.sjscycles.co.uk/pletscher-es ... prod17246/ . I'm not sure how such a figure translates into practice (for example if the bike is near the vertical whilst propped, then only a fraction of the bike's weight goes through the stand compared to if the bike leans more solidly into the stand?). This is the first time I've seen a max weight given and this helps understand why I had one snap?
In summary - out of ignorance of the potential tube-crushing and max weight limit, I have been very happy with this prop-stand. Would I in retrospect have fitted this stand if I'd known what I know now? Probably yes for a steel frame but not otherwise.
