Hi there,

Where do you see that 17c info? I am on the Veloflex site now and I can't find a limit. Or are you referring to the ETRTO guidelines published a while ago? These link below shows the image Mavic published:

There, it shows a 25c tire suggested to fit into an 18c max rim.

Is this what you mean by 17c max rim internal width? Or is it specific from Veloflex?


ETRTO is on the box. Minimum is 13mm and maximum 17mm (inner rim width). If you mount any non-cotton tire (stiff vulcanized 120-180 TPI), you can safely ignore ETRTO, mostly due to pre-shape of a tire. In other word, you can mount 25mm Conti 4000S II tire on very wide 23mm (inner width) rim and ride it for years! In contrast, cotton tires (supple unvulcanized 280-360 TPI) are not pre-shaped and very soft sidewall hence ETRTO guidelines should not be ignored.

Thanks for that. Looks like it may still work alright on some wide rims as others in the thread on max rim width are reporting.

So,

I just got the delivery of the tyres and tubes.

Here are some photos for further info, especially since the Vredesteins are a bit obscure:

Vredestein Superiore avg. weight for 25c: ~231g
Veloflex Master 25 avg. weight: ~206g

Bead to bead measurement, inside to inside of bead

Vredestein Superiore 25c: 6.2cm
Veloflex Master 25: 5.3cm
Schwalbe Pro One 25c: 6.2cm

If you look at one of the photos, though, you'll see that although the Veloflex is a thinner tyre overall, it has a slightly wider tread...Maybe Veloflex thought that 25mm meant a slightly larger tread and a tiny little bit more of body compared to 23mm? I mean, that's a 9mm difference between the "mainstream" (if we can call it that way) 25mm tyres and the Veloflex...?

Mounted the Veloflex today. They went in by hand only. Not easy, but not overly hard either. If you do the "take the slack off opposite from the valve first" technique, they do in. Maybe my rims are a bit smaller than usual.

I'll save my comments and check back with you after I've done a good amount of riding on them so as to get familiar with the feel so I can then mound the Vreds and do a comparison. Quick impression on 40km: different feedback than Pro Ones (as expected), silent, feel a bit slower, measured straight of the bat at 90psi at 25.2mm. Best config I got so far is 75 front and 85 rear.
