Curious because I used to have a bike built for 650b that made me fall in love with the rim size. It was sadly stolen and now I have a bike that could accommodate both tire sizes listed above.
The arguments here are going to be pretty much identical to the long running debate in MTB over 27.5" vs 29".
https://www.theproscloset.com/blogs/...waAt_oEALw_wcB27.5” MTB wheels
- Quicker and more playful handling
- The traditional choice for downhill riding
- Smaller wheels are generally lighter, stiffer, and stronger
- Good option for shorter riders
Who’s it for: Riders who prefer playfulness, maneuverability, and style versus outright speed. Riders who specialize in jumps, freeride terrain, or bike parks.
29” MTB wheels- Rolls over rough terrain and obstacles more easily
- The traditional choice for cross-country racing
- Becoming popular for trail, enduro, and even downhill racing
- Good option for taller riders
- Who it’s for: Riders who want to maximize uphill and downhill speed for racing or crushing Strava segments. Riders who want to stay up-to-date with the latest tech.
