Velocity Razor -> width?

Quoted message said:

Would I be able to use these rims at all? I do XC only.

Yes. These are perfect!

What is the suggested max size tyre to put on them?

2.1 tires should suit you fine. I run 2.4s on my XC rims, and some say
these tend to "roll off" the rim, but I run higher pressures than most
(50psi) and I've never had a problem.

I could end up making them road wheels, I have 1.50 slicks, but would
they fit? 20mm seem so narrow. And I don't go on the road.

You should be perfectly alright. With the trend towards lighter and lighter
wheels, wheels have to get narrower to be able to attain those weights.

Thank you Phil,

Another question, I don't know PSI, but would I be safe running 3.5 bar on
these rims without stressing the rim sidewall too much?

I didn't know they had a website, I found it and there they say it's a road
rim. I installed my 2.1 Kenda onto the rim and it was a bit harder than on
my 24mm. My obsevation is that the tyre on the 20mm rim is about like a 1.9
on a 24mm rim.

I do a 100km race on Saturday which is mostly a gravel road used by motorcar
traffic with some forest patches and mountain passes, it goes up and down
from 1200m alt. to sea level.

So I am seriously thinking about building these wheels as a test, since the
riding will be light with only 10km singletrack climb with moderate
technical stuff. I'm thinking that I will be faster with the slightly
narrower tyre on the type of road surface.

Thank you so much!

If road tires with 120psi could be run on this road rim, then you should be
fine with 3.5 bar (51psi).

You might have a 650c rim instead of a 26" rim. The difference in diameter
is roughly 571-559 (12mm). The rims themselves should say exactly what size
it's made for, either 571 for 650c or 559 for 26". If your tire will fit,
then I wouldn't worry about it too much. It might go out of true a little
more than usual, especially at a 295g weight! Also make sure that the tire
is seated in the bead well... sometimes the bead doesn't quite make it into
the groove. Spin the wheel and watch the rim/tire junction to check for
this.

I just checked the website and they make a 26x1.5 Razor, so you might have
the right one after all.

Sounds like this would be a nice race wheel if you ride it real smoothly.

You won't notice a speed difference on the road unless you actually increase
your tire pressure. The width of the rim only affects the volume of the
tire/tube.

Whoops, I meant 395g.
