Tool Fool - 27.2 seatpost solution

[lconley]

Cyclus holder and handle and 27.2 seat tube reamer (very sharp). 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.

Thanks Laing. 

I'm glad to know about this tool.

I'm wondering about the pros and cons of changing a 26.8 or perhaps 26.6 which most of my bike are to a 27.2.

Well, I can think of several pros...

I just wouldn't want to mess the seat tube up if there are cons.

Laing, 

Happy birthday!   :) 

I'd love to see a report on how you found the process once you've done it. easy to difficult, quality of result, etc. 

Thanks!

Hi Laing,
I also found a supplier from Europe and plan to purchase the Cyclus holder and handle and 27.2 seat tube reamer.

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.

I called Dave wages at ellis cycles to ream my hunqapillar to 27.2 from 26.8, and he wouldn't be do it because of the risk of damaging the frame.  You may want to consult an expert before doing this.

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.

I'll echo Julians request as to an update when done.  I would like to do the same to my Atlantis.
