I'm looking for an inline 25.4 diameter seatpost at least 400mm long with 70mm minimum insertion.
I know it's far from ideal but if I can find one I can use my jump bike as a SS
Closest I've found is 400 long with 100mm insertion
Anyone seen anything?
will the frame cope with only 70mm minimum insertion? often only the seatpost is marked, but frames have a limit too.
have you tried thomson?
Dave
Frame should be ok, 70 puts it below the TT junction
I can't see the minimum insertion on the Thomson posts
All Thomson posts have a min insert on them, something like 3". Personally I wouldn't be happy with a seatpost inserted to just below the TT junction. I'd want it a couple of inches lower to be safe.
Oh and Thomson posts are 410mm at their longest.
Nice mix of imperial & metric there but a 3" insert on a 410 post should work, now to sell a kidney to pay for it
Indeed, but its probably easier to visualise 3" than 76.5mm. Keep an eye on the classifieds. I think FSA do a longer one, possibly 450mm.
I have a silver Thompsen 27.2 410 with layback kicking around in my shed. Email in profile if you are interested.
EDIT: Sorry, just realised that the size is wrong for what you need.
according to their website FSA don't do any 25.4 posts & Thomson only do one in 350 length
