26 to 650b comparison?

[d_douglas]

Sounds weird but can anyone tell me what the relative diameter of a 26 wheel with a 2.2” tire compared to a 27.5” wheel. I assume that the tire would be less than 2” in order to fit in this frame?

It is a very cool frame that I’ve lusted after for over a decade

D-pal, I don't know the answer to your question but I converted my Surly trucker from 26 to 650b x 48mm (Compass Switchback Hills). To be more specific, the bike was designed for 26 inch wheels but when I bought the frameset, I went ahead and installed a 650b size wheelset on it so that I can use the Compass SBH. I really like the smooth and cushy ride. It does feel like I am sitting taller but I soon get used to it.

For comparison, I found a picture of another pal's LHT using 26 wheels.

650bx42mm

Well
That’s depressing. I guess this bike would stay as a 26er then in order to maintain big tires.

What brakes did you use to make this work? Looks like a type of V-brake. Makes sense that moving the pads up the V-brake arms could adjust/compensate the cable pull so they'd work directly with the shorter pull of road levers directly (or did you have to use something to adjust that?).

My standard answer to the 'what's the difference between...' question is always: 650b is basically a 26er that rolls better.

Still feels just as playful and maneuverable, just faster.

IDK about hos to make em work on non-disc frames 'cause my last 26er had discs. Nor do I know the specific outer dia. You'll have to measure

Good luck!
