Mx to 27.5 front and rear

[The undecided]

Hi

As an experiment I recently swapped my Phase Evo 29” front wheel and tyre with a 27.5 wheel and tyre and can’t believe how good it feels so far.
Having come from years of (normal) mtbs with less aggressive geometry it was a bit of an eye opener to now be riding an emtb with a 64 degree h/a and a 29er front end. The added grip,roll over and cornering confidence once I got used to riding the front differently is welcome but what I don’t like is the greater “flop” from the front especially negotiating slow technical descents or just riding about on road to/from my local trails.
Fwiw I’m now running with a 27.5”
Continental Race King which as expected is also much more quieter on road sections and doesn’t bombard my bikes down tube with stones etc the way my Kryptotal did off road and the bike now feels much quicker and livelier to ride and still handles great.
Has anyone else made this change and kept it this way?

My trek rail i put on 27.5 all round about 18 months ago
for me at least its not going back on 29" wheels ever
The bike is so much more precise and maneuverable

I tried 27.5 all round on my Rail about three years ago. Unfortunately, I thought it dropped the BB too much meaning pedal strike were inevitable and when riding rooty or rocky trails the 29er front rolls better.

Welcome to the past.

Full 27.5 are very great as they are very very nimble. Major drawback is that they have more difficulty on rocky section like rock garden or roots.

I would be very careful so as the BB can drastically go down so some bike will be very ugly to ride like no more pedal possible over some terrain.

For what and where I’m riding this bike nowadays dual 27.5 feels ok at the moment.When I get the chance next year to hit a trail centre I’ll probably switch back to the 29er front.
I’m well aware of the negatives of a low BB etc,but as an experiment it’s been worth the change (for me anyway) so far.

fwiw, one of my buddies is doing the same as my converted MX bike but he is on 27.5 - old bike I guess.

For what we ride definitely a big advantage for speed, but I still like the 29 also for easier to roll over forest stuff.
