The Geax Mezcal 29 Inch Tire is fast becoming an XC race legend due to its light weight, low rolling resistance, and cornering performance. Geax uses proprietary polyamide threads and material positioning to achieve substantial anti-pinch-flat protection and cut prevention, which makes the Mezcal one of the best racing tires on the market.
Weaknesses: horrible in muddy conditions, wet roots/rocks. bad on wood surfaces and slick conrete
Unfortunately my only experience with these so far has been in wet conditions and in an indoor bike park. Both left much to be desired. The only positive in both these conditions was that they are a pretty fast tire...but that does little when you have no confidence in the cornering ability. These things unexpectedly wash out on pretty much everything I've tried them on. I left them at 3 stars because they appear to be a very good tire for dry riding and they were okay when the ground was just a bit loose and wet. Outdoor, they are all over the place on any wet root, snow, and mud. Pretty much impossible to climb anything and downhill was just scary. Going into highspeed turns they completely washed out...like someone pulled the carpet out from under me. Indoor, they were okay, but again if i went into a steeply banked turn with too much speed they would slide out from under me badly..especially if area had some debris. Would take my Nevegals with with the stick-e compound for dh/fr any day over these

Strengths: This is a super fast tire. Really, really roll well in dry conditions. Peace of cake tubeless setup with Stans rims. I would recommend using the tire on rooty, fast hard pack ONLY.
Weaknesses: Puncture ! Puncture ! Puncture! Three new tires this year, all three punctured on rocks within the same month of mounting the tire. Two tires in the same ride. Why did I choose to put them on this year? Best result I ever had with these tires mounted. On Dry, Rooty single track.Like I said, they roll super fast, but with a risk. This is my first internet review ever, because if you ride or race on rocks, Look elsewhere.. The weight savings is definitely not worth it. Good luck.
Super fast, great tubelessl, they hookup fine in dry- damp conditions.
Too light for riding rockier singletrack. Bad with punctures.

Strengths: Rolls fast, real fast... came with my bike...
Weaknesses: I'm going to be religious when going downhill, if you have rocks, or the trail is fast and curvy, do not use them, poor grip and vulnerable sidewalls, 3 flats in 3 weeks, and in low and high pressure, they don't mind, not jumping or doing crazy stuff, just rolling, even some Maxxis Larsen TT held a lot better...
I'll keep em for backup, and pavement rides... not much else..
Wild on the downhill, because of flats, front will not turne, bad washout on a rocky trail, never happened before!!!
Strengths: Very fast rolling tires,Very light weight,predictable feel
Weaknesses: Could use more grip in the loose sand, but then you would get more rolling resistence
Really ecstatic about the performance of the tires,very lightweight and good on dry surfaces, fast rolling tires,but alittle loose on the climbs, and doesn't clean off mud to well but who really goes mud bogging on a super nice bike.
For dry trails with some rhythm and fast sections this is definitely the tires for me!!

Strengths: Low rolling resistance - this tyre is superfast!. Grip - the design actually works really well, in that the side knobs are very firm (unlike too many others), so when it is railed at speed they grip amazingly well for such a fast tire - on hardpack (as its designed for).
Weaknesses: Tread wear is fine, but the casings just dont seem durable enough. I've owned a number of them (coz of strengths) but the casings fail - either the wire shows through inside (causing rubbing punctures), or the tyre 'bulges' if it gets worse, all with just not enough miles for me any more. I havent had a major problem with punctures; I check casings regularly now & replace them before total failure. In NZ they're quite expensive too (I'm average height & weight)
Fast as hell on hardpack - both straight & round corners, but just not durable enough - unless you use them as race only?
Similar Products Used: Maxxis wormdrive (scary); Specialised: Rocksters (these did rock!), Roll-X (too slow on hardpack), Fast-traks (even slower, & poor grip at speed on hardpack); Kenda Nevegals (pretty good - but not as quick as these); old Michelin Wildgripper semi-slicks (v similar & great, but also not so durable)

Strengths: - Great cornering; - Good grip in drypack conditions;
Weaknesses: - The Mezcal is far from being puncture proof; - The tires are quite difficult to fit without wobble;
When mounting these tires, I had much difficulty with alligning them right. They wobbled far more than other tires. I've spend a *lot* of time trying to resolve this issue, and I've fitted many tires to this date, but that didn't help. Fortunately, after a few hundred kilometers, the wobble was pretty much gone.
On a dry trail this is an excellent tire. It corners exceptionally well for a semi-slick, has quite good grip and makes you go really fast!
Unfortunately I've had *many* punctures using this tire. I experienced this on tracks where I've never had much trouble before, using similar tires. Last summer I totally ruptured my rear Mezcal. Though the conditions were pretty rough, I was still surprised on what happened and how drastic.
On the trail this tire earns 5 Flamin' Chilis. However, due to the poor fit (wobble-issue) and the many ruptures I've had, I only give it 3 Chilis.
For the new season I'm going to try the new WTB Vulpine semi-slick.
I'm trying to decide which tires I should run. These would be mounted on an old ('86) Titanium DBR hardtail frame, which has limited clearance in the chainstays, so nothing over a 2.1 on the rear. I'm trying to keep weight down, but I'm not racing, so I'm willing to give a little of the weight bac ... Read More »
I just got a pair of tubeless Geax Mezcal 2.1 tires.
Its almost like a semislick thread which doesnt inspire me much confidence.
I couldnt find any reviews on it.
Does anyone have any experience on this tires?
I havent tried them on my bike yet so i can still trade them for something knobbier. ... Read More »
Anyone try the GEAX Mezcal. They look like a nice race tire for HP to semi-loose. It looks like they have fairly substantial intermediate and shoulder knobs for an almost semi-slick. I use stans and am also interested in the new TNT versions which are designed to be used with sealant. Anyone hav ... Read More »
