Strength:

All around greatness, best brakes in the business in this category, rear suspension with DRCV feel way more plush than 120mm!

Weakness:

DRCV fork is good but definitely not great and it's a challenge to dial it in right.

I bought my 2012 ex8 in December of 2011. This was my first new mtb since I purchased a Pro-Flex Beast new in 1996. Obviously, comparatively speaking the Trek is LIGHTYEARS ahead of my old Pro-Flex. But, after riding it now for going on 4 years, I've come to truly love this bike. It isn't perfect as it took way too long to get the fork set up the way I like it. And even now it's not quite exactly as I want it but the rear suspensions excellence more than makes up for it. As many posters have proclaimed, the bike just does everything well. What stands out to me is how well it goes downhill! 120mm "trail bikes" shouldn't be able to do what this bike has done for me. It just RIPS! Especially after I went wide and short in the cockpit layout and upgraded the tires from the abysmal old design XR3s to the phenomenal Frank Stacey designed XR4 Team Issue rubber. And of course tubeless. The bike is a monster and so playful on every little rock and bump on the trail if you so desire. If you want the suspension with eat it up for you. I LOVE this bike!

Seeing as I gravitate to more DH centric rides, my next bike will almost certainly be a new Remedy. If my ex8 is this good I can imagine the Remedy will be that much better for All a Mountain riding.

Bottom line is; if you're in the market for a used trail bike r you're lucky enough to find a 2012 ex8 NIB, GET IT! You won't be disappointed.

KNUCKLES   [Dec 30, 2014]
Strength:

hydraulic disk breaks that respond quickly, 26" wheels, its very lightweight, the wheels and tires are tough and can take a beating.

Weakness:

The chain flops around to much on rough terrain and jumps.

I have a 2012 ex 5 with 26" wheels, the only way to go, handles very well on any terrain. Handles down hill bombs, jumps and turns with ease which you won't get with a 29er. 26er 's rock and roll and 29er's are a macho fad that is fading fast.

John blaze   All Mountain Rider [Jul 23, 2014]
Strength:

It's lightweight, the drcv shock and fork is amazing, eternal cable routing, rims are tough, most people I ride with are on 170mm travel bikes and I do everything on this bike they do and also the things they can't like really technical rock gardens and long rooty climbs.

Weakness:

3x10 should be 2x10, handlebars to flat, bonty race light grips only good if you have tiny hands

The people I ride with are all on 170mm travel bikes and I do all the downhills they do 5 foot drops etc but faster and also the stuff they can't do like technical rock gardens and steep rooty climbs. My next bike purchase will be a dh bike from trek just for the lift assisted runs that I plan on doing but for everything else I ride it's the fuel ex 8

Millimetric   Weekend Warrior [Jun 23, 2014]
Strength:

Frame strength. Geometry. Rear suspension. Head angle. Tubeless ready wheels.

Weakness:

Tires, though tread pattern is good I lost count of flats. Don't attempt a rock garden with these. Fork, no compression damping. QR rear axel. Elixir 3 brakes, very noisy.

I'm critical with some of the component choice but must admit it is a Fuel EX level 7 so the value for price is good. I knew I would have to change stuff gradually to turn the bike into something special: fork, out Float 32 evolution 120 RL OB; in Float 32 factory series 120 FIT RLC. Drivetrain, out Deore cassette, cranks, shifters and SLX rear derailleur; in X9 type 2, race face NW 32t 1x10, XT cassette with 42t cog. Brakes, out with elixir 3; in shimano XT ice tech. Tires, out with XR4 experts 2.30; in MAXXIS Ardent 2.25 rear, Minion 2.40 front, tubeless (best investment ever). Add Reverb dropper plus wtb saddle plus ODI grips plus wider handle bar, and last but not least swap the 90mm stem for a 60mm. These upgrades have transformed the bike. Now I will not give up this 26er. Although it could use a bit more travel it's still awesome on the trail. I would not use for XC though, too heavy at 29.7 lbs. EX7 has turned into more like EX10 if Trek made one. But the value was in the frame and rear shock. The investment was worth it. The bike was good, now it's really something else. In the end it's the little things that count (I knew the first day the grips had to go).

Trekker   Cross Country Rider [May 25, 2014]
Strength:

- The best looking bike for the past almost 5 years since I bought them among all the other.
- Light, can pull the with one arm, made from lightweight red aluminum.
- Fast uphill or downhill 26' wheels are FAST, don't buy the 29 ' macho crap, 26' rules. 29's are heavier!
- I weight 120k"g and they didn't break once! very tough.
-

Weakness:

Well, I haven't found a reason to buy something else them for 5 years, so... they are perfect for me.

I rode cross country, sports 22km"h average speedaround the town, on hard terrain in the mountains (all mountain), they are really good bike. Looks awesome, color scheme is the best around from Trek for the last years , fast and light.

Stephen   All Mountain Rider [Apr 29, 2014]
Strength:

Plushness, rear suspension design, G2 geo, looks, once it has speed it holds it very well.

Weakness:

A tad heavy (30-32lbs) Sram X5 not the highest level shifters but still crisp wheels are kinda heavy and feels sluggish when you start out.

Suspension on this bike feels very plush to the extent I almost am afraid of bottoming out the rear suspension a lot, the full floater rear suspension pivots on the 2014 version does feel like the advertised "bottomless" even without the DRCV fox shock. I'm kinda tall (6'1") and so 29ers feel more natural for me and this one takes the cake, the G2 geo allows me to keep the fun flickable style of riding. My friends are turning over to 29ers slowly and currently my friend who normally beat me (he rides a 2013 GT Karakoram) now will be next to me or behind me. By the way this bike looks sooooo much better in person. getting up to speed can be kinda hard as it feels sluggish due to rear suspension bob and weight but once the bike gets going on either a downhill or a flat it keeps going and is rather hard to stop but the brakes do a swell job. My cross country biker friends beat me on the climbs but once we turn around the trail and go down I slaughter them if your looking for a Fuel EX bike look at them in person first and demo one then make your mind.

Bryce Kelly   All Mountain Rider [Apr 20, 2014]
Strength:

Plush, light weight, Agile, easy and smooth to ride. Wide handle bars for better control, brakes are actually very good, Suspension system and Suspension components are solid.

Weakness:

tires are garbage!

I like to ride rocky rough downhills because of the technical challenge and pure enjoyment I get from it. This bike handled it quite well besides the tires. It was smooth and light making it very easy to control. Peddling up the hills with the suspension and how light this bike is makes it easy. I would have given this bike a solid 5 stars but the tires are absolutely terrible. This bike is awesome and when my wife rides with me she gets it and loves it. Replace the tires and you have a great bike.

Jerry   Weekend Warrior [Feb 16, 2014]
Strength:

The CTD coming standard is great..well made bike...

Weakness:

Tires are pathetic I know they have to put as much Bontrager items on this bike but those tires are horrible for my terrain, no pedals included.

Overall I like this bike much better than my Haro hardtail, I am though rather disappointed in the value for the money, I mean for $2000 and you do not even get pedals!!!! I had to buy a set at local dealer on top of the bike cost, yes there are many choices in pedals etc but at least allow $125 of the total price to go towards any pedals the rider would like in the bike shop. The tires are pure junk in place of mass producing every bike with XR3 how about you do research and find out if in a region such as Nevada that Kenda Nevegals are top choice here slap those on the bikes for shipping to all your NV dealers. I am happy overall with the bike and love it but for the price, put some real tires on it and allow the purchase of good pedals as well.

Stevenmillerrn   [Nov 14, 2013]
Strength:

It rode great until it broke, twice

Weakness:

I do not think that it will support heavier riders. I broke the top tube along with the seat post tube on both a 2011 Fuel Ex and the replacement 2012 Ex while riding the same trails. I am a 230 lb 47 y/o nurse trying to keep his blood pressure down. I'll let you decide how aggressive I was.

I upgrade to the Santa Cruz Solo C (aka 5010) and I am issue free after 130+ miles on the same trail
