    Date Reviewed: July 30, 2005
    Duration Product Used:6 months
    Price Paid: $100.00
    Strengths:Looks good, paint dosen't scatch easily, reasonably quiet and it can take a beating. Its pretty easy to set up aswell.
    Weaknesses:no matter how well set up it was, my chain still occasionally came off and it is very difficult to get the chain back on without tools. Also the roller soon gets dirt in-between the roller axel making it noisy and the little bolts soon become rusty.
    Similar Products Used:goldtech chaindevice that comes with 24Seven speedset - VERY GOOD
    Bottom Line:The best things about this chaindevice are its looks and its toughness. I can't recommend it because it couldn’t fulfil its purpose of keeping the chain on and there are better chain devices that cost less yet do a better job.

    Date Reviewed: November 19, 2001
    Duration Product Used:1 Year
    Price Paid: $125.00
    Purchased At:Velomania
    Strengths:THICK outer plate, easy to setup, very quiet, quite adjustable (inner guide moves in and out via two small allen bolts)
    Weaknesses:I hate tightening little bolts into my frame. There are two small bolts tightened at the Bottom bracket to keep the guide from rotating. Does the job though.
    Similar Products Used:Underworld Slalom guide

    Bike Setup:Balfa BB7, Hayes, RaceFace etc.
    Bottom Line:Great guide for the money. Support Canadian Business!

    Date Reviewed: November 11, 2000
    Duration Product Used:3 months
    Strengths:this device keeps the chain on all the time (unless your rear mech is badly set up and does bad stuff - but nevermind that) and it hardly rubs at all. The bash plate thing is also really handy when your trying to ride up stuff.
    Weaknesses:You need a really straight pair of cranks/axle/spider/whatever
    Similar Products Used:AC sport chain device (don't buy even when cheap)
    DMR speed guide (nice)
    MRP copy (feeble)
    Bike Setup:DS1, Pace RC37s, Hope up front, bmx stem (everyone should get one they rule)
    Bottom Line:This product should be the way all chain devices are made. It is strong and easy to fit (even for me!), it works, it's smooth, quiet and it comes in a range sizes so you can fit almost any chainring. Buy it

    Purchased At:Bicycle world in home town
    Strengths:It keeps the chain on all the time and in the time that i have had it, the chain has never fallen off. It is also really easy to set up and as strong as an ox
    Weaknesses:None are you mad
    Similar Products Used:MRP world cup 1, DMR speed guide

    Date Reviewed: April 18, 2000
    Favorite Trail:Lynn Woods, Wakefield BMX track
    Duration Product Used:6 months
    Strengths:Fairly Strong
    Keeps the chain on(after modifications)
    Looks cool
    Weaknesses:Top guide piece is not thick enough, leaves a small gap between the guide piece and bash ring. Chain comes off thru that gap.
    Similar Products Used:(this Product is the same a the Sun-Ringle Spin doctor)
    Bike Setup:Santa Cruz Chameleon, Z3 LT, XT drivetrain, other assorted ds/urban assualt stuff.
    Bottom Line:This guide system works well, after modifying the upper guide piece. I've thrown my chain a couple times, and then I figured out the deal. Add washers in between the guide plate and the upper guide piece, to space it out until it becomes flush with the bashring.
