Will my frame take 27.5/650b wheels?

[ishaw]

Bought a bike recently that was advertised as a 27.5, but on arrival it was wearing 26 inch wheels.

Annoying: yes. I've a 29er and various 26ers so fancied having a 27.5 to try.

The frame has adjustable drop outs, and the 26er wheels were fitted with maxxis minions in 2.35 which appeared to have a fair bit of clearance.

I don't want to buy a set of wheels to find they don't fit, but as I have a set of road wheels, I thought I'd see if they fitted as they are 29er really.

I appreciate that road tyres are not a good fit/comparison in reality but it's all I have to play with.

Based on the pics below showing 700c/29er clearance, and the room to manoeuvre with the drop outs (set as how they arrived with me for thec26 inch wheels), what are my chances of success in fitting some 27.5 wheels on the frame?

Are there any other measurements or tests I could do without shelling out for a set of wheels and tyres?

Re:

I hope it does, just bought some wheels......

Looks like a lot of room for manoeuvre there. Worst possible outcome with that would be fitting smaller tyres than you wanted.

Re:

I hope you are right as I've ended up with 2 sets of 27.5 wheels.

2 sets? Were they on offer?

Re:

One set was, one off here. I suspected the pair I bought on offer wouldn't materialise as the rest of my order was shipped without them, so hedged my bets when I saw a set on here. Had confirmation that the original set have been shipped today.

I can always send them back I guess.

Trying to cut down a lot, not grow more. It has crossed my mind though.

Re:

Looks like there is about 20mm clearance at the seatstay bridge, assuming that road tyre is a 25mm(?) that would give a current outer wheel diameter of 672mm so the maximum radius will be about 350mm to allow for mud clearance. A 650b wheel with a 2.35 tyre would give you an outer diameter of 703mm and therefore a radius of 351.5. Probably less than ideal but it would be fine.
