TBH for me the 29er wheel size felt right, an hours test ride convinced me, so I bought one.
Thats not to say my 26er bikes now feel completely wrong, but after riding one and swapping back to the 29er, it feels ‘better’ to me (I’m more confident in it because of it).
The added benefits are that it rolls better & the traction is better, but these aren’t the reason I bought one (but are bloody great benefits in the middle of winter).
So decide which feels better for you, getting a proper test ride would help… we can’t tell you, yes we can probably say the 29er is a slightly poorer spec (not checked but historically they are) for the same money but this is negligible if it feels right.
