Looking to replace the alloy seat post on my touring bike. Of course it's 30.8 mm, not the most common size, but do-able. I see the biggest selection for that size is carbon. Some cost $20, others cost $200. Presently looking at what's called 3K carbon.
Any education and opinions would be greatly appreciated, regarding reliability, warnings and any special things to keep in mind.
Thanks
My question would be why? There is virtually no weight difference. The cheaper seat posts are very likely to be seconds from other makers. And the correct sizes of aluminum seat posts are usually available for not staggering costs as you often run into with carbon seatposts.
Another thing - many of today's carbon posts have that damned one bolt adjustment that is forever slipping. You can get two bolt adjustment aluminum posts that are extremely easy to adjust to the proper tilt.
