Which Pedals ?
 

Looking to upgrade to a clipless pedal- Lightweight and a nice solid platform. Any input is appreciated

With clipless, the shoe is the solid platform. Get a good stiff shoe that fits properly.

I like shimano two bolt. Others like Crankbrothers, others like Time. There are many good choices. Pick one and fly with it.

If you ride hard, CBs may not be the best choice, though I personally like the eggbeaters
the Mallets are a good option if you need double duty flat pedals

Switching to clipless you need to look at shoes first. There are 2 basic types, road and mountain (this may have changed since I bought my last pair) Most road shoes are difficult to walk in (you need to protect the clips from being damaged when walking on hard surfaces. Sometimes you'll see cyclists doing th heal walk). Mountain bike shoes have recessed clips, so the are easy to walk in. Myself I only do road cycling and I wear mountain shoes with recessed clips. Once you find shoes, then look for pedals, I use Shimano PD-M520. Then you'll have to consider cleats (cleats are the part of the shoe that clips into the pedals. there are 2 basic types single direction release and multi-directional release. I use the multi-release.
Do not attempt to buy shoes online. you have to go to your LBS and find a pair that fits properly.
I hope this info will help you while you research what's best for you.

Sorry guys I fudged this thread up, I meant platform pedals- not clipless. Sorry

Any input is appreciated as always.

I have spank spikes platform pedals, I think they do a pretty good job, although I haven't tried a lot of others.

How do you upgrade to platform pedals? Platform pedals were invented when bikes were invented. What were you using before platforms? wooden sticks stuck into the crank holes? LOL

More and more people are swearing by platform pedals on mountain bikes these days...and platform pedals are getting better and better.

You do realize that most bikes come with **** platform pedals. By upgrading you get a higher quality pedal making a riding experience better and less broken shins from slipping off the pedals when your riding in dirt. That is how you upgrade platform pedals.. amazing right.. LOL moron

Depends on how much money you want to spend and how aggressive you want the pins/grip. For a good slimmer pedal for a decent price the VP Harrier and Straightline Amp have done well for us. For something more beefy with max grip the DMR Vault Mags have some of the tallest pins I've seen. Flats kinda go as such: under $80 you'll get something fairly well built but probably heavy and bulky. $80-$130 you'll get something well built and either slim, light and not the strongest against a pedal strike, or well built, a little builky, and super strong. Then above that $130 level you'll get all three, well built, slim/light, and super strong. Figure out what you need and pick accordingly from a respected brand. And I'd personally make sure it's rebuildable with replaceable pins at minimum.
