I rode 26 for many years. I switched to 29, liked it. I switched back to 26, didn’t like it. Now I’m sticking to 29. I’m tall, always felt that 26 was a bit small, then 29 came out…
I’m getting old, but bikes are getting lighter and stronger. 29 is almost as light as 26 was 15 years ago. 29 helps me to roll over square edged bumps a lot better. So although I’m getting older, I can ride the same trails with less effort. Offsets the age thing.
I used to ride a Yeti 575 with very wide tyres. I now ride a fully rigid 29er with very wide tyres. I can almost ride anything with the rig 29er that I used to with the 575. My next bike will be a SB95. 29er and FS? Awesome!
