i need help deciding what to run on the rear of my new norco moment frame

it only has rim break mounts and ive never even looked at the rim break rims out there whats a good choice? i've heard suggestiong like the sun rims ryno lite xl's and the king pin?? ......whats the deal with pinned versus welded?

The Avid Single Digit Ultimate is something you may want to look at.
Or the Avid SIngle Digit 7 ('05 brake, I'm pretty sure) if you find it.

The Moment frame is a trials frame, which is why it doesn't have disc mounts. Most disc mounts are not strong enough to stand up to trials riding, and hydraulic rim brakes on ground rims are easier to lock up anyways.

Eh... No on those brakes. They're decent, but not great.

If you want to stay with a v-brake, the Avid Arch Rival calipers with Paul or Avid Ultimate levers are pretty good. But I suggest going with a Magura HS-33 hydraulic rim brake with salmon kool-stop pads.

For rims... Those Magura rim brakes can crush some weaker rims. The Sun Big Fat Mammoths held up great on my Surly. Halo makes some nice rims too. The Rhynolites haven't been that great for me.

a bunch of my riding buddys have had them and say that there a sick brake but that youve gotta do alot of tweaking not much of a worry??

I've used the Magura HS-33 hydraulic for Trials before; Sick as brake, the rim i was using had no modifications at all and it still grabbed prime!

As for rims, Try the Sun rims King Pin, big burly rims with super tall, dual width sidewalls, they also make them in Chrome as well, so that will improve your braking power too (Or you could get black and put some rough sandpaper to the braking surface).

Since the Maguras i've used XTR v-brakes and Avid single digit Ti, both of which are sick brakes; Both super light and have incredable power; So if you don't want to get Hydraulic, these are another couple of options.

the king pin is a pinned rim whats the deal with this as opposed to welded?? weaker??

Mavic EX721's are far and away the best rim brake compatable 26" rims that ever have been available. They are expensive, but they actually last under hard riding, which is more than I can say for almost any other rim I've ridden.

I think the best rim brake out is Avid's SD Ultimate, but you can get good results with any brake that doesn't have linkage plates, a good cable and housing, lots of lube and a halfway decent lever. The fancy stuff is nice to have, but not necessary.

I agree w/ Garson on the brakes. For rims I've had good luck with RLXLs but I've never ridden 721s.

The Magura HS-33 is absolutely amazing. They do take a little tweaking in the beginning and you may not want to run hydraulic brakes on an urban bike, but they are unstoppable. They will crush cheap rims too, I've seen it once.

I've got an old Mavic 521 ceramic rear rim, with an XTR v-brake with plazmatic clear pads and an old Salsa brake booster, mated to an old set of XT v levers. It's a super solid combo, but absolutely NO modulation, as soon as one of those sticky pads touches the ceramic surface, it's locked up- good for trials, bad for manuals (for me).

I couldn't be more happy with this set-up for trials, I was just looking for a cheap(er) option, and don't have HS33 mounts on my echo anyway.

 

[rocpyro]

I just got avid ultimates for my trials bike. Levers are in the mail. It's gonna be sick!!!! And yea, manuals SUCK with a good(read "ground") braking surface.

Sun BFR rims and Avid Arch Rivals...doubt you'd be bummed with this setup even when you under rotate. I've landed more than a few 310's with these and they are still holding up well (the rims, not the brakes, I run 990s on my jumper).

True that!

I am a 190# hack and have a 721 on the rear of my steelhead. That rim refuses to flatspot or even come slightly out of true. I have been trying to kill it just so I can get rid of the POS XT hub its laced to and get another one built up with a proper SS hub. It just keeps going and cant be stopped. . . .like the Terminator.
