Is a maxis high roller effectivly a 650b

A 2.4 tyre is about a 27.2-3 I think. 650b is about 700mm diameter depending on the tyre.

That would explain why when I used 2.4 Rubber Queens it felt like my bike had caterpillar tracks and just rolled over everything, no slipping, no going in the holes just amazing :). Shame the mud clearance was non-existant

…which is 693mm diameter so not far off 650b size with a 2.35 High Roller or similar if the above is correct.

does that mean my 29er with 2.4 tyres is a 30.5er?

2.4 Rubber Queens are epic!

OP – yes, every size.

It’s a con!

Yes, if the highroller is a 2.5″ and the 650b rim has 1.5″ tyre they will be approximately the same size. If the 650b has a 2.5″ highroller then no.

A 650b rim is almost exactly 1″ larger in diameter than a 26″ rim.

I can tell the difference between a 26″ 2.25 tyre and a 650b 2.25 tyre. Both Ralphs. There is a different feel to the bike. For the same size tyre, 650b will be about 1″ larger diameter.
