BOTM: Gerard's own "Keep an OPEN MIN.D." - part 2

Gerard Vroomen - 19-Apr-2022
Last week I already gave you some insights in why I picked which parts. Just one thing on the tire choice. I picked the Schwalbe G-One Pro because we like it, it was available and the tan sidewalls nicely match the saddle and bartape. But also because it's a good match for the HED Emporia wheels. The Emporia carbon rim has a 26mm inner width, and HED recommends a minimum of 32mm for the tire so all good. 

In truth, this is a little aggressive when compared to some other recommendations, but for example ETRTO is notoriously conservative. Traditionally, ETRTO would recommend a rim no wider than 20mm for a 32mm tire. That of course is a bad recommendation, but it's "official". Updated ETRTO guidelines will likely show that 28-32mm tires all top out at 25mm inner rim width while a 35mm tire is "allowed" to go on a 26mm rim. Also that doesn't make a ton of sense; if a 28mm tire can fit well on a 25mm rim, then why couldn't a 32mm tire fit on a 26mm rim? But it's a lot better than it was.

Anyway, the 32mm Schwalbe tire actually measures 34.2mm on the HED rim and has a very nice shape together. Even more importantly, it rides like a dream and fits nicely inside the frame and fork with 5-6mm clearance all around (which is more than you need for a road bike really, so you could go a little bigger even). But remember that there are production variations too, so if you get your own G-One Pro tire on the same width rim, it may shape up a bit differently.

As you can see, the whole build is focussed on comfort and long-distance riding, not on making some ultralight bike. But still it came out lighter than I expected, at 7.4kg with the XL frame. I can't think of anything I would change on this setup.

Comments & Questions

Hello OPEN, good morning.
We are a small bike store in Seixal, Setúbal Region, Portugal.
We are Trek, Kona and Megamo dealers.
We have a good client willing to buy a OPEN WI.DE bike.
Is there any possibility of our company buy only 1 bike from you at retail price in order to serve our client ourselves?

Kind regards,

Tiago Silva, from Ciclobaía
