For about 5 years upto about 2 years ago, I've done a short 5 mile each way commute and due to changes to my job, I'm hoping to have a 10-15 mile each way commute, mostly on NCN/cycle paths and road, which I'm hoping will take around an hour door to door.
I also do a bit of recorational/family cycling with two young boys 5 & 10 around parks few feilds etc.
I'm pritty much decided on the new bike, Mason Bokeh (I'm also tempted with the resolute steel) but prefer the versaltility of the option of wider tyres.
As the main purpose is the commute I'd be going for a light package, with a Son Delux hub I just can't decide whether to stick with 700c or try 650b wheels?
I'v done some reading and understand the overall diameter are similar and that 650B spin up to speed quicker and lighter than 700c but may feel a bit sluggish on road and as slightly less efficent and slow down quicker.
I've had 26'er and 29'er mountin bike with wider knobbly tyres which were just knackering and slow on the road.
I'm not planning to do lots of proper off road stuff and think something like 700cX35 or 40 be fine and allow a bit of off roading.
My previous road bike was 700X23 then 25 from 120psi to around 90psi and I didn't really notice any difference in comfort or effienciency and never had tubeless, with low pressure, but always understood more contact patch the higher the resistence, so not sure how much difference a 650b would make with a wider softer tyre.
I also think as dynmano hub front wheel, a smaller, 650b wheel spinning more/faster as I understand would be more efficenent.
It probably won't be until March next year, so I could start with 700c and come next winter go for a set of 650b and swap between the two ?
I also can't decide what size tyre or pressure be best for both wheels?
