[Closed] Are all 650b bikes sluggish compared to 26” ?

Must have missed that. Remind me again why it was worthless ?

to sum up, the author of the study himself admitted that the results werent statistically significant plus the terrain chosen was a bit naff

There’s little actual weight difference in the frame between Bronson and Solo. The forks etc being smaller so the Solo is lighter.

I have a Bronson and my old 2010 714 Zesty, both 1 x 11. I still ride both, the Bronson is faster overall. Both are mediums but the Zesty is the same size as a large Bronson. I like the smaller frame on the Bronson its simply more manoeuvrable and the suspension is better. 650 tyres provide more grip patch contact with the ground which I like for technical climbs.

When I went out to replace the Zesty I developed the wish list from my Zesty geometry which I liked. I discounted bikes that were massively outside the geometry. My heart was set on a new Zesty which I demoed. Then I got a demo on the Bronson. I knew it was the bike for me.

If someone beats you up a hill – its because their fitness is better than yours (given the bikes are roughly the same weight).

Also its not all about the speed up. Alomg and down is just as important, which bike overall did you like best? Choose that one.

I forgot I had started this thread.

I ended up ordering a new Nomad CC frame. After trying my mates 26" version and loving it and reading how good the new one is I thought I would give one a go. I'm still not happy about being forced down the 650b route but a good bike will be a good bike regardless. I have ordered some light bicycle carbon rims to try and get the wheels as light as possible whilst hopefully still being durable.
Annoyingly I have to wait a few weeks for the frame and ??? weeks for the rims.

Could it be a compatibility issue?

Did you make sure to drive to your ride in an Audi? I think the silver A4 estate works best.

Is it hard work being such a knob?

What's the deal with Audis, they're great? Mine has 19inch rims. I'd like to try one with 18inch rims to see which one is fastest, most comfortable etc. But on looks alone the bigger wheels look best! Going up hills I find a lower gear helps and I don't have any issues in keeping up with Fords or Volvos or even those pesky BMWs. Out on the flat cornering and 'making progress'is excellent but the downs require the use of the brakes to keep the speed in check. I'm not sure wheel size will really come into it. Surely you just get the one that you like and can afford?

Wrong thread?

"Are all 650b bikes sluggish compared to 26” ?"

Having only ever ridden 26ers I can say with complete confidence that 26ers are faster 😉

@trailofdestruction, thanks for the video links, I enjoyed that. Looks like the industry have pulled a fast one with 650b ... glad I stayed with 26" wheels and wasn't bitten by the 650b bug.

I don't think one test (in a very specific set of circumstances with just one rider) can be taken as "evidence" - whether that's evidence of performance gain/loss or the lizard rulers of the earth forcing you to buy a 650B bike.

I'm now on a 650B bike of the same travel as my old 26" - it's faster on the clock when pushed hard, and seems to carry speed better once up to speed. It does seem [I]slightly[/I] slower to accelerate, but that might be a relative gearing thing, a rotating mass thing, or suspension kinematics. Or it may be in my mind.

If anybody's got some 650b wheels and tyres they don't want I'll take them off your hands, they would fill the frame and forks on my old hardtail and look better than the 26" wheels.

same way some bikes feel lighter than they are

750b is horrible Vs 26" though.. not so much to do with acceleration just the simple physics of gyroscopic direction change and a taller axle height 😉
