Overall: I've been mountain biking for 9 years, the first 3 years very often, the next 5 less so. This last year has seen a move of house and a return to regular mountain biking. And the point is ? - well, I treated myself to a new bike but didn't move the rollamagjig over. I've just spent the best part of 2 hours trying to fix my wayward shifting, if i set the tension for good upshifts it wouldn't go down and vise versa. In my book that could only mean one thing, a bent hanger. After alot of messing about, the derailler off many times, it was still no better. Thats when I remembered cleaning the loop of cable at the back, it was fixed in minutes.
I used the rollermajig for ~8 years and never once had bad shifting owing to dirty cables. Without the rollermajig, i needed to clean the cables out within a few rides of autumn arriving!
Strengths: er, none really apart from being able to run a shorter length of gear cable.
Weaknesses: i couldn't get the xt set up on my hardtail to shift properly at all with it, it would undershift in both directions making shifts a russian roulette experience.
Overall: i couldn't get mine to run right from the start, possibly i had a duff one after reading the other reviews! in the end i simply ran a longer length of cable and it now shifts as sweetly as it's supposed to.
Strengths: Simple design - less to go wrong A noticeable improvement to your shifting A fit and forget part - always a good thing in my book.
Weaknesses: Can seem pricey for what looks like a glorified plastic wheel. Incidently, I picked mine up at last year's cycle show, £4 - bargin! As one of the posters quoted above - the plastic "ball" is very easy to lose when you come to install it or replace your rear gear cable.
Overall: One of those things where your thinking - it surely can't make that much difference. Take the plunge, your kick yourself for not buying one sooner.
Strengths: On my bike it cuts down on the cable length protecting it from damage. It also improved shifting loads. It is now light fast and super accurate
Weaknesses: Its easy to lose the small ball when changing cables
Strengths: Fit and forget (nice on a bike these days) Cheap (wiggle 10% discount) Works!
Weaknesses: Pricey if you pay RRP.
Overall: Makes shifting that bit smoother and less inclined to miss gears etc. Especially good on a small DH/FR hardtail that makes the cables snake round fairly sharpish, smoothes out the angles it has to bend through so I guess that would make cables last longer.
For as little as they cost, the overall benefit has got to be worth it compared to the cost of the rest of your transmission.
Strengths: Low friction shifting, consistent performance in poor conditions, reduced need to change rear outer cable. Improves performance of any grade of rear mech.
Weaknesses: Need to trim outer cable very accurately for optimum positioning/performance of device. (Best to fit new cables at the same time to maximise short/long term performance). As the inner cable forms to the tighter bend - albeit friction free - the rear mech cable adjuster will need slight tweeking for several rides.
Overall: Imagine Shimano just upgraded XTR rear shifting - that's the advantage this device brings. When you consider the design, all the component parts and assembly, its good value really. Consider how much you would have to pay for a higher level rear mech/shifters/quality cables to attain a similar shifting performance upgrade. Buy one.
Strengths: Smoothens the cable flow and makes shifting nicer.
Weaknesses: Little expensive at £10 for a small plastic thing.
Overall: Brilliant little invention although it is £10 which is worth it for the performance it gives but it is a small plastic thing which would cost avid about 10p to make.
