Strengths:    Great and helps you lock the rear very easily. I have only used it on the back so don't know if its any good for front but should be the same. They also have great looks.

Weaknesses:    Sometimes makes you lock the wheel too easily on road and drift

Bottom Line:   
Great stopping power

Strengths:    I upgraded my bike about a year or so ago from a heavy low spec tank. The bike I bought came with these boosters. Initially I felt that they were too powerful, this is probably due to the fact that my previous bike had cantilever brakes. Also I had quite a nasty accident where I went over the handle bars and broke with my face. In response to this I remove the brake boosters and bought a giro switchblade helmet (the business). The more trails I did and the more comfortable I became with the bike, I felt like I needed more breaking power. At theis point I re-fitted the boosters and they gave me all the power I needed.

Weaknesses:    If you are a novice they may be too powerful (see above), as the majority of the people reading this won't be then there are none. What you buy is what you get.

Bottom Line:   
This is an excelent product which will enhance the breaking power of any v-brake system.

Strengths:    1. Looks.
2. Stiffness
3. Weight
4. Works very well.


Weaknesses:    1. Um...scratches easily??? Hold up - this is a mountain bike product review, right? The only mountain bike I've seen that doesn't have any scrateches is the one thats never been off-road.
In other words, If your that worried about scratching the thing, don't buy it or do the laminating trick like mentioned in the preceeding post.


Bottom Line:   
A very nice buy, even though it was a little expensive. I bought two of these boosters because I knew they were hard to find and pricepoint was having a good deal on them. I knew for certain that I needed one on the rear of the bike, and I felt that one for the front would improve power and put an end to some brake squeal. They have worked very nicely since they have been installed, cutting down on squeal and definitely improving power and modulation. I can feel the difference every time I brake hard. They are perfect for the XC rider/racer who is weight conscious or for the rider who doesn't/can't move up to disc yet but wants almost disc-like performance out of their V-Brakes. I thought my XTR's were a powerful upgrade to my braking systyem. I didn't know how powerful until I slapped a pair of these babies on. 5 flamin chilis for overall. 4 Flamin chilis for values, because these things are expensive!!

Strengths:    Awesome. This is cutting edge technology at it's pinnacle. This unit weighs about the same as a piece of toast and is strongerthan a southern accent.This thing is a work of art, no frills, no hype, just stiff carbon that works. It's good looking too for all us chi-chi fans, with classic carbon web design and the graphics are deep set into the high gloss finish, so they will never scratch off.

Weaknesses:    During instalation it became apparent that adjusting the cable anchor bolt would be a challenge. The booster is now so close to the brake arm that fitting a standard allen wrench behind it is impossible. Two remedies here, either replace the allen anchor bolt with a traditional style bolt or, cut down an allen wrench to suitable size making a custom tool.(this was my remedy and it works great)

Bottom Line:   
Weigh your options when looking to purchase a brake booster.there are so many models to choose from some good and some bad. In my case, it all added up to shimano.

Strengths:    It works, looks better than most others if that matters, pretty buff for the weight although I don't exactly crash very often, won't rust or corrode, did I say it works.

Weaknesses:    None that I've experienced, considered discs on my XC HT racers due to severe brake faaaade and seat-stay flexion, but didn't want to 'pork-up' the bike (I've already worked so hard to drop it below 20lbs), I thought it would be a gimmic, but it works. Adds some weight to your ride (if you care).

Bottom Line:   
I had pretty bad brake fade and squeeling from the XTR brakes/levers (only in the rear though), especilly on the decent (I'm only 145lbs), and the stays were flexing like Conan the Barbarian. This was the magical "Lucky Charms" fix I needed. Buy one if you want disc-like power from a linear brake or your bike sounds like Celine Dion on a tricky decent.

Strengths:    1. Light without sacrifying any material.
2. Nice design
3. Very stiff
4. Vibration absorbent


Weaknesses:    So far so good

Bottom Line:   
This booster is extremely stiff n light. It can also a vibration absorber when u brake due to it made from carbon. i read all the reviews that having a small weakness of this booster may scratch easily. So i suggest this may avoid by paying some bucks to buy a transparent laminating paper to paste on it. I tried this n it may prevent any deep scratches. BEST BUY.

Weaknesses:    Imprinting scratches of easily - but then, whoopdeedoo.

Bottom Line:   
Put it on my new hardtail as it noticeably suffered from more seat stay flex than my dead Zaskar. Massive improvement and certainly not a fashion accessory. Great and USEFUL product.

Weaknesses:    Cost too much man, but what do you expect when you want the

Bottom Line:   
As your attorney, I advise you to go down the store and buy one. Ive melted these down and sniffed the vapors and boy I can tell you these are one of God's own prototypes.
Doesnt take much to put you over the edge man, just grip that brake and shell pull up on a dime.

Once more man, How much for the chimpanzee?<- the question mark is emphasized.

Submitted by Jon H a Racer from Monterey, California

Date Reviewed: July 13, 2000

Strengths:    Extremely Stiff

Weaknesses:    External clear finish cracks/chips at mounting point over time which results in deeper crack development which equals you need to replace it every few years.

Bottom Line:   
Have tried a few different kinds and nothing eliminates flex like these do. On the front I can only see one post move ever so slightly while cranking down on the brake lever. In the rear I can not detect any brake post movement at all. Have used these for about three years and they make a noticeable difference in control and braking power per effort applied. Especially notice when doing slow technical steep downhill the brakes are what I call linear - they don't get grabby or squeaky.

Only suggestion I have for Shimano on these is to include larger diameter washers where the booster bolt goes through. This would spread the load out more and tend to reduce the tendency for the boosters to start cracking at that location. Did upgrade on my own with larger diameter thick stainless steel washers and it does do the trick.

Bottom line - if you want to elliminate all flex from your brake posts then buy a pair of these.

Strengths:    Helps against frame flex.

Weaknesses:    Really enormous, expensive as hell, Salsa booster looks way betta and comes in many colors

Bottom Line:   
it helps against flex, looks pretty cool but is very large and obtrusive. I would get the Salsa booster even though it weighs like 20 grams more. This thing is way too expensive unless you are a total weight weenie.
