Pondering going from current 27.5 wheels and tyres to 27.5+ sizes. 

However, came across a bike advertised running 29 front and 27.5+rear. My LBS does not have such combo to try out. Anyone running that setup have any views, pros and cons? Also, what is the best plus width for all round use?

Background: It would be a new bike so I am assuming the geometry would be built for the setup of different sized wheels/tyres. My current full sus mtb is an all mountain one so an all rounder and used in the hills, cross country, single trails, trail centres (incl reds) and the likes all for leisurely fun. I don’t do extremes but my bike has to cope with a variety of terrain incl rocks, small drop offs, tree roots, rough loose surfaces, undulating fast downs yet steep ups in moderation.

Trying to maintain a nimble capable all round bike, but improving rolling ability over tree roots/rocks, and more importantly comfort through less vibrations if this is possible without sacrificing too much! I had a 29er years ago, but much prefer the agility of my current 27.5 on 2.25 tyres.

Interesting, thanks. Looking at that and other videos, a 29 up front may well be an advantage for me. 

On their medium and large sizes, Liteville spec 29er front / 27.5 rear. Normal size, not plus, but I reckon it can't be too bonkers if a super-thoughtful manufacturer like Liteville is doing it.

Have a look at the Cotic FlareMax 29er.  Mate ride ones and he flies on it (up, down and across).

Thanks all, appreciated. I should get a test ride on a full 29er as it has been years since I was on one. Also, if I found a local shop that had a 29/27.5 to compare against tha would be great. More food for thought, thanks.

They are well sorted now, should be a different experience from a few years back. 

Saw this and thought of this thread:

Thanks. I’ll have a read later at home; not made any decision yet anyway.
