Strengths
These things are big... and I mean BIG - 90mm x 90mm on the actual platform itself. This makes for a very good platform for your feet. Add to that the biggest pins I've ever seen (about 5mm clearance from the pedal face) and your feet ain't going to slip... if they do you'll know about it from the blood gushing out of your leg from said pins ;-)
The axle is heat treated 4130 ChroMoly so it's going to take a great deal of punishment before anything happens to it. Even if the worst happens and they bend said axles are covered with a 2 year unconditional warranty.
They look great. Ah - vanity you may say... and you'd be right. But when something looks good... it just looks great.
Weaknesses
At £58 they ain't cheap. But quality just oozes fro them so I guess they were worth the money.
The main weakness about these pedals is the fact they will always rotate so they are vertical to the ground when your feet aren't on them. This is all well and good for my standard freemount but makes just about any other mount (rolling, jump etc.) that much harder as your feet aren't coming down on a horizontal pedal... and with those pins you'd better hope you get it right first time!
The pins in them are very, very long. You'll here people (including myself) talk about how "evil" and "nasty" they look. That may well be true but the Slack pedals are the most evil and nasty I've come across so far. This really isn't a bad point because they grip so well. As you might guess I haven't had them ripping at my shins yet so my opinion just stated may well change ;-)
After a couple of days riding one of the flesh ripping pins had fallen out and others were working towards doing the same. They have now been fixed in place using some thread lock compound. The good folks at 24seven sent out some replacements quick sharp.
