Here's Jan Heine's latest on wide tire road bikes, or "All-Road Bikes.."

I guess that link takes you to the most recent edition of his blog, so
when this post gets old you'll probably have to scan downwards.

Wider tires is something that could help a lot of 'normal' riders, but
running fat(ter) tires also requires running fatter rims for them to
work well--and most people still don't bother with that part.

I've seen online a lot where someone says that they have a bike with
30mm tires and ask if they can put ~45's or whatever on it... -and
everyone else says "yea sure, if the tires will fit in the
frame/fenders". And it's true that it works, but it works lousy. I'm
usually the only one pointing out that you don't get the full benefit of
fatter tires unless you move to wider rims as well.

It goes something like this:
1. The only reason to run fatter tires is to run them at lower
pressures, to absorb road bumps better.
2. But if you get wide tires and mount them on narrow rims, then you
have to keep them inflated to fairly-high pressures to keep them from
squirming and folding over in turns.
3. So if you mount a fat tire on a skinny rim, all you end up with is a
much heavier, hard-riding tire. The fatter tire's greater cushioning
ability is lost with the raised inflation pressure that becomes necessary.


I totally agree. A wider tire on the same rim inflated to same pressure (that is what most people do) results in a much harsher ride. I see no point in getting wider than 25 mm tires on rims normally used for road bikes.


As for Mr Heine: I consider him to still be green, as he hasn't
graduated to recumbents yet.


Who is this Mr Heine?

https://janheine.wordpress.com/ He's a guy developing a market niche. He sells Compass products and is now making Rene Herse products under a some sort of agreement with the Herse estate. https://janheine.wordpress.com/2017/...y-of-function/ https://en.wikipedia.org/wiki/Ren%C3%A9_Herse

Probably made in the same Chinese factories as Velo Orange: https://www.compasscycle.com/product...ry/rene-herse/ WTF? $550 for a triple crank? Yikes.

I remember back in the mid to late '70s going to the Wheelsmith shop in Palo Alto. It was hardly more than a shed, but it had all these old bikes out front -- including a few Rene Herses with odd-ball derailleur systems and old rusted parts. It was the one and only time a bike seemed creepy to me.. https://tinyurl.com/yblk6cqy A few hundred yards away was Palo Alto Bikes with Tom Richey building modern frames. I liked fast-back stays, although some of his weren't all that well executed, IMO. At the time, my index frame for awesome was the California Masi. https://belle-macchine.com/2014/03/1...gc-california/ Then I ran into a Bruce Gordon http://www.classicrendezvous.com/USA...lman-Jones.htm
That renewed my interest in fast-back stays. Caylor's fast-back stays were nice, too. Back then, nobody was impressed that you wore wool or rode a steel frame. Maybe you could be more cool than the next guy by drilling a few more holes in your crank.
