Extreme Steering, Inc. (aka ESI) was founded by Gary Stewart in 1999. Using his experience and background in the aerospace industry, Stewart began developing products for the bike industry that included super absorbent MTB grips like the ones seen above. Made of 100% silicone, the Chunky conforms to your hands for maximum grip and shock absorption. Not only are they extremely comfortable, they're also able to withstand severe temperatures and conditions without disintegrating or decomposing. With so many positive benefits, it's no wonder why ESI grips are so popular -- they work great!
Have them on all my bikes now, was a dedicated Oury guy but with or without gloves these are awesome grips
Easier to install than expected - I used isopropyl alcohol and saturated the inside of the grip. They slid on without any issue and stayed in place within 10 minutes. Only problem is they damage easy, but that is not enough of an issue to rate lower!
Esi chunkies are the most comfortable grips ever. No more numb hands. I used various ODI lock on grips and they are good but still give me numbness on long rides.
I own a Specilized's EPIC and because of the XC´s trails here in Chihuahua, mostrly hard packed soil, small rocks and sand, my hands hurt and became numb with the original equipment. I owned ERGON`s and SPECIALIZED's grips but the ESI Chunky's are way more effective and comfortable; and the price is awesome. It was a little bit difficult to install them but after all they works well.
Don't be fooled by all the others, ESI Chunky grips are as good as it gets! I ride in ultra endurance mountain bike events and these are the most comfortable, lightest grips I have used. Application is simple and once on, they don't move. The chunkiness makes them extremely forgiving and adds a thick piece of spongy grip between your hands and the trail. You won't make a mistake buying these grips.
These grips are ok. I bought them because they are light, but I switched back to Oury ODI clamp ons because I think they are more comfortable. The ESI's felt like they packed out and I could feel the handlebar through the grip. Otherwise, the red color was nice and they didn't slip or tear.
Love them for the price. Extremely comfortable and cheap and comes in plenty of colors to match the bike. Only complain would be that on strenuous rides gloves are a MUST...sweat makes these very slick.
These are all I use. The chunky grips are more comfortable than the originals, and very lightweight for those weight weenies. Would've given them 5 stars but they can get easily tattered if you lay your bike down. Also, hard to clean but that's if you go with a light color like I did. -Carlos
I'm torn between the feel of these and the convenience of lock-ons. I absolutely love the way they feel. While riding along, they are the best grip I've ever had, and I've had Ergons, ODI, and dozens others. On the flip side, I've been using lock-ons for so long prior to these, that I had forgotten the headaches of installation, removal, re-installation, and of course those stupid little plastic end caps. If ESI would create a lock-on version, it would get 6 thumbs up.
Fantastic grip and feel, just the right amount of thickness. I had odi rouges before these and they are the same thickness... just beware of the white ones, very hard to keep the clean white look, bit that should be obvious.
Awesome color options, easy to install, long life, can ride with or without gloves. These are the best grips I've used!
I bought my first pair of these last year, and the only complaint I had was that being orange, they got dirty QUICK, and dirty orange looks pretty bad. I have a problem with the ulnar nerve in both hands, so I go numb easily, yet that first pair seem to keep that at bay. They tell you to mount the grip with the 'fat' side facing your palm, and I remember having a difficult time deciding which side was in fact 'fat'. I must've got it right however. Second time around was just last week, and this was a whole other ball game. Firstly, I didn't have any air at the time, so going by the directions and using alcohol and/or Windex was a PITA. Again I had a tough time trying to decipher which side was thicker than the other, but this time I think I installed 'em thin-side towards my palm(s), as five minutes on the trail it felt like I was pounding my hands into steel rods. When I got around to trying to remove them to try to spin 'em around, I used the same technique with the Windex. Unfortunately, because they fit so tight on the bars, you need to use a screwdriver or whatever else you think will work to pry the grip up off the bars so the Windex can work its way in and around. Despite plenty of Windex getting behind the grips, the freaking things barely moved. The second time I used the screwdriver I ended up tearing the grip, so needless to say they came off uber quickly after that. You NEED air to install/remove these grips, and I don't think getting the thicker side positioned properly would've 'fixed' my problem anyway, as when it's that hard to determine which side is thicker than the other, there's just not a whole lot of difference between the thin side and the thick side. Why I didn't have a problem the first time around with these things, yet had such a big problem the second time I'll never know. I DO know that I'm not gonna screw around with anything other than lock-ons from now on. I'm old and don't have the patience anymore
Installed these to replace the stock grips on my Trek mamba and they are worlds better at absorbing vibration than the thin rubber stock ones. I do still get hand pain at the outside of my palm so I'm going to try Ergons this season, but these are a nice simple basic grip that does a good job of taking shocks. They are not the most durable grips out there however I have had them for about a year and they are missing some chunks from incounters with tree branches and such.
I ride rigid SS and my hands usually get a little numb at the start of rough rides. I was contemplating carbon or ti bars when a friend suggested I try these grips 1st. Glad I did, best grips I've owned. and at that price its a no-brainer.
I was hesitant to buy these grips since they look pretty basic/ordinary compared to others. BUT, since purchasing these and riding for a couple months now, I'm in love. They're a bit difficult to put on, but once you ride with them you'll feel the difference. The vibration in your hands/forearms is greatly reduced for a more comfortable ride. Good stuff!
East to install but took some getting used to. They dampen vibration very well and do not get sticky like rubber grips. the end caps leave a little to be desired, they pop out very easy.
The grips are extremely good. They weigh next to nothing and are nice for people with bigger hands. They give you awesome grip and best yet work great with gripshift.
they really take out some rattle and grip super. lots of colors are cool. but i got black, because i am afraid. also, the silicone doesn't turn into nasty black goo like other grips. Installation can be a little trying, i just used a lot of rubbing alcohol on my 2nd bike and they went on great. like half a bottle. esi grip are very fun. recommended.
silicone grips huh think i'll give em a try.
