I’ve had an Orange P7 that came shimmed from the factory and my Raleigh twenty has a seattube that’s swaged down to size only for the top 1”/1 ½” so kind of the same amount of contact as a shimmed one and both of these were/are fine.
I’m looking for a suspension post for my gravel bike and being able to buy a 27.2mm one instead of the 31.6mm that the frame natively takes would open up a few more options.
I've had good luck with them on rigid posts, but I'd check that whatever shim you use is as long as the seatpost manufacturer's recommended minimum insertion for a suspension post as they're likely to be much more fussy about any elastic bendage.
I'm also a shim in the Stanton to run a poxy-looking 27.2 dropper because the proper sized OneUp dropper had issues when clamped with enough force to hold it in place. The 27.2 with shim works better.
Shimmed seatposts, yay or nay?
