Geax Blade 33 - 70PSI Min????(9 posts)

Geax Blade 33 - 70PSI Min????mcbaker55

My new Geax Blade 'cross tires just arrived and the sidewall says that the minimum inflation pressure is a whopping 70 PSI! What gives? I don't even run my Ritchey Excavaders that high on the road and for 'cross, I'm in the 40 - 45 psi range. Has anyone tried the blades - what pressure are you running? Any pinch flat problems? They certainly seem low volume (unmounted) compared to my 35 Ritcheys. Thanks.

Those are primarily a grass tyre, so they definately are low volume and high-pressure. You want to run them high, otherwise you do not get the same kind of hook up as they 'blades' or lugs are not terribly stiff otherwise. I cannot say that I recommend them for many surfaces outside of grass.

Hope that helps...

I just got a pair of these from a friend and have been riding them for a month. My first big ride on these tires was the IRON CROSS race (I finished with a broken seat post) in extremely rocky PA. I might be one of 10 that didn't get a flat and I ran the whole race at 65psi. I have run 55-60 at the local single track with out incident as well. They definitely shine on grass though. Very confidence inspiring on the green.

My only other experience with CX tires has been Kenda KrossSupremes (35mm) and Kenda Kwicks so I wouldn't consider myself an expert.

Hmmm, that's interesting - Geax seems to bill it as more of a mud tire. I wonder how it performs in the slop.

Blade's have a supple casing...AJS

...so they can have higher pressure and still get a good grip/low rolling resistance.

I used to love 'em for MTB tires, and the Cross Blade is excellent too.
Are they decent in the mud?mcbaker55

This weekend will probably be wet with slippery clay soil. I'm not sure whether to go with the standard Michelin Mud (I only have one, so I'll have to buy another) or whether to try the Blades. This course can be quite rough, so the high pressure of the Blades does cause me some concern. Any thoughts?

The Blades can be used with lower PSI...AJS

...it's not going to hurt anything. It's just that with their casing design, higher PSI's can be used also while still maintaining a good grip. Other tires such as Vredestein's Campo are similar.

I'd have to say that the Geax Blade is one of the best mud/soft conditions tires I've ridden, at least the MTB version is. I can't say specifically about the Cross Blade as I've not yet used it, but I would think it's at least pretty good in those conditions, considering it has the same type of tread pattern and casing as the MTB version.

I have run the MTB Blades (1.85, 2.00, and 2.25 sizes) at 37-53 PSI without pinch flats, but of course those are much larger volume than the Cross Blade. I'd say try 'em at various PSI's to see what works best for you, as each tire model and riding condition is different.
Great, thanks all! (nm)mcbaker55

I have been running a set of the blades for a couple of weeks now. So far I have been very happy with their handling in the mud. They seem to grip very well in almost any condition.

I would recommend running them at least at the minimum 70 though. Last weeks cross race was a rough and bumpy race, so I tried running them at 60. As I came around a corner the tire came off the rim and I blew a tube.
