Rated 4.6 out of 5 by 16 reviewers.
Rated 3 out of 5 by Nice pedals but questionable durability. First the good. These pedals give a really good first impression. They're staggeringly light, compact and smooth turning. Fitting couldn't be easier. They offer plenty of grip for the rubber soled trainers I normally ride in. I've had the odd pedal-strike over kerbs and whatnot, due to incompetence on my part but the materials and finish have stood up well. Now the bad. The other day, after ~2000 km of use, the bearings in the left pedal disintegrated, first becoming "notchy" and then allowing the pedal to move outwards on its spindle. After riding the 12 km home from where the failure occurred there appears to be nothing where the bearing balls should be but grease and steel filings. I don't know what happened. As noted, there's plenty of grease in there so lubrication failure seems unlikely. I'm hoping that I might be able to replace the bearings. It would be good if I can because, apart from this failure, which may just be bad luck, I really like these pedals. Even if I can't, for the price I might risk another pair in the hope that they'll last a bit better. 11 August 2014
Rated 4 out of 5 by Простые надежные педали Пробежали у меня уже 5000 км. Пора заменить шипы - слизались. Хорошо держат удары и камни, неприхотливы в обслуживании. Нормальная вещь, стоит своих денег. 23 July 2014
Rated 5 out of 5 by Очень легкие педали. Вес 232гр. пара. Внутри с внешней стороны пром, с внутренней втулка скольжения. Очень хорошо держат ногу. Проехали более 1000км - полет нормальний. Следите за пыльником с внутренней стороны, он предотвращает попаданию грязи во втулку скольжения. Не мойте их под высоким давлением! 17 July 2014
Rated 5 out of 5 by nice looking , light weight look great on bike , nice and light , smooth action, never fitted pedals with an alen key but this was a doddle, cant get any easier. 13 July 2014
Rated 5 out of 5 by Шикарные педали! Переживал, что после широких пластиковых платформ будет неудобно. А вот ни разу! Оказалось, даже намного удобнее (по крайней мере, мне). 21 June 2014
Rated 5 out of 5 by Ottimo pedale Questo è un ottimo pedale, leggero, solido, robusto con un ottimo grip. 06 June 2014
Rated 4 out of 5 by Decent Flat Pedal My over all impression of these pedals is that they look a bit cheap and plastic in real life despite their magnesium alloy construction. Grip seems okay in the wet so I assume dry will be fine. Bearings spin a lot nicer than the previous wellgo pedals these are replacing. These pedals are also perfectly symmetrical which was my biggest gripe with my old ones which means no more flicking them to get them the correct way up. 01 November 2012
Rated 5 out of 5 by Incredibly good all round pedal I had a pair of Wellgo pedals fail on me before so I was wary of these but "took the plunge". Honestly these pedals are just about perfect. If you are looking for a lightweight flat pedal, stop looking and buy these. 23 October 2012

What tools are required to fit these pedals?

Are any special tools required? Could they be fitted at home or is it best to take them to a bike shop?

Answer: 
The initial thread can be tightened by hand then an Allen Key through the back of the spindle.

If you not have a set of Allen Keys; your Local Bike Shop may be the best option.

Answer: 
A 6mm hex key is all that's needed, plus whatever tools may be required to get your old pedals off. Just remember that the left pedal is held on by a left-hand thread and the right pedal by a right hand thread. What this means is that, when looking at the left pedal from the left of the bike, to tighten the pedal the spindle must turn anticlockwise.

Similarly, when looking at the right pedal from the right of the bike, to tighten the pedal the spindle must turn clockwise.

Whether it's worth taking to a bike shop depends on many things. Fitting the new pedals isn't really a shop job but getting the old ones off could be, if they've been in place for a few years. Steel spindles in alloy cranks have a habit of welding themselves into place over time. A shop will have the tools and skills to get around this but many amateurs will not.

Answer: 
Yes; these pedals have a 9/16" diameter spindle which is the correct sizing for the pedal boss on the M131 crankset.
