Rebuilding pedal

So I bought a set of MKS RX-1 pedals used on ebay recently, they were advertised as being smooth as glass but one of the pedals feels terrible. Is this an easy rebuild or should I get a hold of the guy and try to get my money back. For the record I would much rather rebuild the pedals for the experience, and I do like the pedals. Any and all advice is appreciated.

Those are sealed-bearings in those. If it's "terrible" - you should be demanding your money back.

That's more than I paid for the pedals, I think I'm going to have to return them...

Open it up and get the number off of the bearing seals or shields. If there is no number measure them. They are metric and you should be able to get bearings here. http://www.enduroforkseals.com/id172.html

$33 for one pedal is nothing. Do you guys realize how much the pedals retail new for?

Yep - $124.95 I believe. They look really nice, too. The fact remains that the seller left out a very large detail when he sold them.

Caveat emptor. I hardly ever deal ebay anymore. Way too much inconsistency from seller to seller.

+1 if you want to rebuild it the bearings are almost certainly a generic size and should be easily available. You could probably spend $3 to $100 each depending on how exotic you want them to be. If there isn't a number just measure the ID, OD and width. Eg. good 'ol 6003 bearings are 17x35x10, 608 bearings are 8x22x7, etc. There's no need to pay more by buying the bearings from a bike shop since the whole idea of using this type of bearing is that the parts are an industrial standard and easily available.

PS, I'd at least ask the seller to pay for the replacement bearings if you do decide to keep them....

I've actually already returned them, I think I'm going to look for a heavier pedal with loose ball bearings. Anybody know anything about the entry level MKS track pedal?

Pedals are pedals (anything metal > $10 anyways). The MKS offerings are perfectly fine. Easily serviceable.

MKS pedals, at lease the inexpensive ones, come out of the box too tight and bone-dry. The first thing you should do - before installing them on the bike - is to disassemble them and lubricate the cups & races with lots of grease. Reassemble and adjust perfectly as you can. And tighten down the lockring good and tight. You may have to try several times before you get it right.

The second pedal, and all after that, will be much easier.

+1
And, after you do that, you should be good to go for a long time.

My GR-9's are almost as smooth as my 1982 Campagnolo Record pedals. Nice!

Do the GR-9's have sealed bearings?

Nope. Loose 1/8th inch ball-bearings. The older Campy Records also have loose bb's. And those turn more smoothly than many sealed-bearing pedals I've examined. It seems to me that very few people these days have ever overhauled their pedals, whereas it used to be a standard procedure.

That's what I was hoping, I'm trying to get away from sealed bearings where I can, I like being able to easily service my stuff. I'm not sure if I want to go with the track pedal or the gr-9, but I'm glad to know they are both loose ball.

Do note - the GR-9 pedals are designed to by ridden with toe-clips & straps. Which can be a shock to those who've only ridden with pedals you attach to your shoes.

I planned on getting toe-clips and straps regardless of which pedal, I love the versatility of a soft soled shoe, as I usually use my bikes as transportation. I have a set of old campy pedals designed with the toe clips that I absolutely love. I think I just had myself sold on track pedals for some reason, I think I got caught up in the NJS thing, I don't know why. The GR-9 probably makes a lot more sense for what I plan on using it for.

Because you want to be a hipster. NJS parts aren't necessarily cheaper, faster or lighter. Doesn't make any sense. Usually it's the opposite of all three attributes.

Well I, too, cycle in cheap sneakers. I'm equally comfortable on the GR-9's, the Campy (Quill) Records, or the quill-types - with toe-clips & straps - I have on my 3-speed PUCH. I'm no so-called (and they wish) 'hipster.' I'm an out & out radical!

I can engage my feet into toe-clips & straps as fast - or faster - than the clip-in crowd on their carbon-framed Poindexter's. Or whatever.

I bet I can clip in and out 30 times faster than you can with clips and straps.

You can and should service sealed radial bearings. The seal is removeable so you can clean and relube them.
That said MKS makes some nice pedals that use cup and cone bearings.
