    Strengths:    EZ to set-up.
    Does the job.
    Very quiet.
    Don't know why I didn't get it sooner.


    Weaknesses:    Instructions are a little hazy... doesn't tell you which roller goes where, so I installed them incorrectly resulting in a lot of chain noise. Finally reversed them, now they are very quiet.

    Bottom Line:   
    When my old Deluxe was still a 3-ring bike, the worst thing that could happen when my chain dropped was a surprise shift into my granny gear.
    Now that I'm only running 1 ring up front, the MiniMe is a necessity. Get it and install it before your chain drops during a group ride and you get left behind by your best buds.

    Strengths:    Fool proof, reliable, You can run a 32t ring- good for urban, trails, and not racing

    Weaknesses:    stock plates

    Bottom Line:   
    The Mini-Me actually served as the patern for the chainguide I run. A buddy has one, and I traced the boomerang on an Al plate and used a plasma cutter to make one of my own. I already had two bashrings, and bought two rollers form JensonUSA. My home made setup works flawlessly. Using two thick bashrings is the way to go. The guy that has the actual Mini me has since bent the heck out of his side plates, and he really doesnt weigh that much. I have cased ledges hard on hop-ups, and none of my parts are any worse for the wear. A+ for the design, C for the side plates, D for the price (if you buy it).Thing is, though, how do you measure Value if your trip to a race is ruined by a lost chain when a hundred dollar part could have prevented it?

    Get this or another MRP chain guide. If you ride freeride or downhill and don't have one of these you are missing out. I will never ride without one again.

    Date Reviewed: November 1, 2002

    Strengths:    Reliability, strenght of materials, bash protection, smoothness of the pulleys and ajustability of the pulleys' height.

    Weaknesses:    The V-plate which holds the pulleys can get loose. So make sure to fiz your BB cup very well.

    Bottom Line:   
    I am not sure how much this chainguide costs, however, I believe it is one of the cheapest MRPs you can get. It is only for elevated chainstay bikes. If you run on a 44 t chainring, you might want to get a chainguide for 44t+ chainrings, that way you get a little more "bash" protection and the chain won't jump off the ring on fast rough sections.

    Strengths:    keeps my chain on the ring and properly tensioned, not too heavy, protects my $44 dh ring!

    Weaknesses:    had to hunt for a good price, lots of fit problems

    Bottom Line:   
    MRP said i'd have to use a hacksaw and cut off the top part of the boomerang, they were wrong, i just had to rotate it backwards a little, not in "optimal position" but still works great. its a great product, i feel it is (along with all other chain guides) way over priced, i was glad to get it for 109.95. also, be careful because of the fit issue, i wanted to run a 40t ring with a slalom guide because they said there would be no fit issue, then when i goto order it, they said its only compatable with a 94mm crank, and that caused a whole mess of trouble. in any case, i have the world cup 1, 44t ring, dura ace 11-23t cassette and couldnt be happier.... for steep stuff, i would want to drop my granny gear 5-10 gear/inches, but other wise all is well, in a few months i'll submit another review
