69er put together and ridden this morning. Basically, fitted my 29er front wheel with the rotor I was using on my 26″ wheels. Dropped the stem by 25mm and that was it. Thought I might need to adjust the saddle angle but since it was maybe a little nose down before, it was fine.
The most interesting thing to report is that there was really very little to note… It rode much the same as before basically. Out of the saddle on climbs the steering was a tiny bit more floppy/wavy but other than that, it really wasn’t noticeable.
As to the bigger front wheel smoothing out the trail, I reckon it did a little but my hands still hurt at the end of the ride (as normal).
Maybe some different terrain to what I tend to ride might show up the differences more though – more rocky/rooty trails are where my 29er is noticeably smoother and maybe steeper trails too (29ers seem to find more grip than you expect).
So, I think I’ll be sticking with 26″ wheels on it for now.
