All The Six Fifty Bees Thread! (650b, 27.5 etc.).

I have built a new 650B wheelset so I thought it might be good to cross post here.

• Bontrager Duster 27.5'' TLR PV 32H Black Rims - 28mm wide outside / 23mm inside
  
• OddityK Flip Flop Black Track Hubs, 3/8" axles, 100mm/120mm spacing
  
• Araya Rebound ATB Road Spokes St Steel P/Gauge Black 272mm & 16mm black brass nipples

Here is what a 700c wheel looks like in the back of the dropouts:

Here is the 650B wheel:

So the 650B/27.5 rim sits back around 2cm (when the wheel axle is sat as far in the dropouts as possible) in comparison to the 700c, giving you extra space radially for a wider/fatter tyres.
You also gain around 1cm in lateral width as the rim effectively sits further back along the drive stays.
