Shimano PD-M647 Pedal

DESCRIPTION

Shimano calls this a racing pedal, and it's easy to see why. The resin cage surrounding the clipless spedal is larger and grippier than the M545/M424 design. The clipless pedal inside the cage is based on the latest Shimano SPD MTB iteration. Making entry easy is the 12.5-degree angle at which the clipless pedal sticks up from the cage. The result is a pedal that's good at shedding muck and is easy to stand on as well as easy to get in to.

Strength:

As the only pair of clipless I've been riding, this model is very easy for clipless first-timers like myself to get used to.

Weakness:

Outer bolt on the left pedal spinned itself free during rides and was lost in the woods. This is a design fault as the bolt head comes in full contact (binding) with the resin cage after tightening, thus during spinning motion the bolt will unwind itself from the axle. This will not happen with the right side pedal as it will get tightened when being pedaled due to thread pattern orientation.

An easy and maintenance free remedy was to get a generic stainless steel bolt of the same thread size at a slightly longer length (5mm) to replace it and add a stainless washer + some anti-seize paste to the bolt head area. This way the bolt head will not bind to the resin cage. 20 rides or so in the woods with some pedal strikes on rocks the pedal is still intact without any need of maintenance.

Currently I'm riding them with shimano MT52 shoes, the resin cage rests in full contact at the foot arch area, thus very stable when unclipped. From my observation of various shoes design, I believe this pedal will work well with shimano "hiking boots" spd shoes like the MT32, MT42, MT53 etc which has a recess in the arch area with rubbery knobs, and less well with XC shoes where soles and knobs are of stiffer compound (slippery feeling when stepping on resin cage) or skateboard style spd shoes where the arch areas are flat.

Strength:

Platform actually big enough to use
Easy to clip in/ out
Can still pedal with cleats on shoes but not clipped in
Adjustable release tension

Weakness:

Can't complain at all

Just getting started back on the bikes after riding and racing dirtbikes in the woods for the last 6 years. I got tired of being injured and having surgeries all of the time.
I was riding alot from 2001- 2006 but only tried 1 set of clipless and hated them so I just used toe clips. I read lots of reviews on these pedals and decided to try them, I have to say I am really happy with them. Haven't crashed yet because of the pedals, I crashed all of the time with the Candies I tried before, I could not get out of them.

Recently upgraded the pedals on my mountain bike with these. I'm wearing the Shimano MT42 shoes with the single-release cleats included with the pedals. These are very light weight and shed the mud really well so far. The MT42 shoes are a trail/commuter style, so the cleat is a bit recessed to enable easy walking/hiking off the bike. The clip-in with the M647 pedals is seamless and easy, despite the resin cage. And during some tricky single-track and downhill sections, it's easy to get back on the pedal and have a good platform even if you don't immediately clip-in. Haven't tried riding with street sneakers, to test the comfort/usability of these pedals without a cleated shoe.

When clipped in, the resin cage provides a nice platform that I like better than my prior clipless pedals with no cage. Seems durable/well-built, but only time will tell. My bike has mostly Shimano Deore LX components that are 10+ years old without anything other than routine maintenance. I'm hoping for the same kind of quality.

Strength:

Easy and fast to clip in - almost no learning curve; ability to clip out on sketchy descents and sharp turns, larger platform adds stability.

Weakness:

Maybe weight, but that depends on whether you're comparing to clipless or platform. Weight at 568g/pair is about 200 grams more than comparable (Shimano XT) clipless pedals, but pretty much on par with aluminum platform pedals. In my opinion, though, any weight gain is offset by performance gains.

Look, if you are anything other than a pure cross country racer, you should seriously consider buying these pedals. If you are new to clipless pedals, you should ABSOLUTELY get these - no doubt about it. I have used regular clipless pedals (Shimano M505), and there is no comparison. The DX (these pedals have "DX" branded on the platforms) pedals are much, much easier and faster to clip into. The platform itself positions the clip-in mechanism at an angle, so all you really do is put your foot on the pedal and push down with maybe a little twist or two of the foot. This is all very easy to do and clipping in usually takes just a second. The added benefit is that this process takes almost no time to learn for someone new to clipless pedals.

For those weight weenies out there, any disadvantage from the extra weight is offset by increase in performance. Not only is it much faster to clip in, you really never have to take your eyes off the road to look down at your pedals. So, you are actually saving time because you clip in faster and thus are able to get into your regular pedal stroke faster. The real added benefit, however, is when you are riding sketchy or technical sections of the trail. You can clip out and still have a stable platform to rest your shoes. Your unclipped foot can be used in turns, etc., without worrying about whether or not you can unclip. Plus, in my opinion, the platform actually enables you to ride better in technical sections because more of your forefoot is allowed to rest on the pedal, which increases how stable your foot feels. The added stability of the platform, in turn, allows you to clip in more loosely than you would with regular clipless pedals, making it easier to release.

I will not go back to platform pedals or regular clipless pedals. These are the best I've ever tried.

a little heavy if you counting grams.

Three years of rocks & roots and they still look good and work perfectly. Broke the cage on my M424's in less than a year. Worth the price, they clear mud and give a great platform to stand on.

Strength:

Adaptability - both a clip in and a platform

Weakness:

Clip in sticks up a bit when using regular shoes

I'm new to clip in pedals so figured the SPD would be the tried and true so I wanted a pedal that would do double duty -- allow me to clip in and if I couldn't or came unclipped then I could stll ride home . . . These pedals were fantastic with adjustable float and the SH 56 multi release cleats on the Shimano MT 52 high ankle trail shoe. Easy to unclip and on the downhills easy to unclip and still have positive control . . . For a newbie these were the perfect set up. Down the road I could easily see removing the platform section by just cutting it off to reduce weight but for now its the best of both worlds.

Best pedal for all-mountain riding I've ever ridden! My riding has taken a decided all-mountain direction this year, and most of the XC trails in Colorado would be all-mountain in many other locations. I've ridden SPD primarily for many years and could be considered and SPD loyalist. I tried Egg Beaters for XC riding and liked them fine, so when my Remedy arrived with Candy Cs I thought I'd install them and give them a try. I found them too difficult to clip into for most all-mountain, or even Colorado Cross-Country, riding. I even considered riding flat pedals after seeing several people riding flats with skate style shoes or the Five Tens. I researched the M647s and ordered a pair for myself - Instant Karma! They hold my foot securely no matter how severe the terrain or hard I bang them. My foot goes in easily - that 30 degree up-tilt on the SPD binding is simple but genius. I highly recommend these M647s as an all-mountain pedal, or even for XC riders who don't mind hauling a little extra weight and want dual-sided performance with flat pedal convenience for quick trips or just don't want to go the campus pedal route. BTW - Shimano has lower-priced versions of this pedal, the M424 and M545 that are reviewed here.

Strength:

Easy to get in and out (good old trusty SPD style) Works amazingly well with recessed cleat shoes. Hard pedal strikes and mid-air "oh-my-god" corrections haven't given me the usual real scary clip-outs. Resin cage takes a beating.

Weakness:

Heavy, but anything worth a damn in the pedal arena seems to be that way, especially for agressive trail riders.

If you want the perfect almost platform and refuse to go back to DX pedals from the BMX days of ole these are the ones. Opinion is out there on the Mallets. These things crush them. I am just not the jumping freak I was as a youngster anymore so it is nice to enjoy the benefits that clip-ins can offer. Everyone in my crew rolls platforms. I hate on them everyday.
