Strengths: Do everything you expected of them very well.
Weaknesses: Broke mine in 2.5 hours!
Overall: I bought these pedals for there mud sheading ability as the standard Shimano system is a nightmare in mud. Initially i was really pleased with them, nicely presented in their box, good instruction including a servicing guide, grease purge system to keep the bearings sweet and a very nice engage/disengage action with no problems at all in mud. The down side is that they only lasted 2.5 hours, towards the end of my first ride with them I hit a rock, pretty hard it must be said but nothing that my old Shimano pedals haven't shrugged off plenty of times before. The result was a bent 'bar' but worse, also a bent axle. Not great. I still like this pedal but think carefully about how you ride, if you tend to break things then these pedals are unlikely to survive long.
(Truly Excellent value if you don't break them, really terrible if you do what i did!!)
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: A decent winter tyre, does most of what you need with no fuss. Grips well on most surfaces, from hardpack through to wet mud, does wet tree routes predictably and sheds well.
Weaknesses: Can't cope with really deep mud i.e. rim deep.
Overall: Seems pretty good to me, grips the varied trails of Wharncliffe better than the WTB Moto Raptor 2.24 I was previously using. I should go for the 2.3 btw, its more like a 2.1 than a 2.3
