"When I replaced the Jones with long chainstay Riv’s (Clem & Gus) the need for Thudbuster disappeared."
Hi Richard, That is a very interesting observation. I have not yet tried using my Gus on long rides and will try it out first. Because of the long chainstay, the seat is more centered and would reduce the direct bounce in the seat. I took a quick look at Redshift but unfortunately, they only have the 27.2 as smallest option. Thanks again. Edgar On Wednesday, November 5, 2025 at 9:33:08 PM UTC+8 Richard Rose wrote: Certainly there are degrees of back pain. Mine required surgery. I installed a Thudbuster on my Jones SWB & it worked really good. When I replaced the Jones with long chainstay Riv’s (Clem & Gus) the need for Thudbuster disappeared. On a related note I was gifted a Redshift Shockstop stem which I have installed on my project bike dubbed “MTBuno” inspired by ROADuno. It works fantastically well. So perhaps the Redshift seatpost is worth consideration too.

You may want to consult an expert before doing this.

I plan to ream my 51 GBW from 26.8 to 27.2 so I could use Cane Creek Thudbuster ST Seatpost. The Cane Creek Thudbuster has helped me continue cycling even with my chronic lower back pain. Could you give some tips or techniques you learn when you reamed your bikes seatpost? Thanks in advance.

For when you really, really want to put that 27.2 lugged seatpost in your 26.8 or 27.0 frame. This will be first put to work on my 27.0 Guv'nor and then my 27.0 Bombadil (already honed, but still tight). Less than $100, shipped from Germany. This is my birthday present to myself for my 66th Birthday.
