Hey Scrod, is the only difference between the Deda RMH01 or RMH02 the top of the bars? the 02 is flat and the 01 is round like traditional bars?

You got it.

Can you recommend me tires that'll blow Conti Ultra Sports out of the water in terms of... Everything? Should I just spend the $100+ on Hardshells?

Scrodzilla 02-24-13 09:46 PM

Ultrasports are bunk. Hardshells are very durable but offer a pretty unforgiving ride. I have a pretty good idea of how I'll answer but what are you looking for specifically?

Dannihilator 02-24-13 09:51 PM

Please check the retrogression thread in the market place.

Scrodzilla 02-24-13 09:56 PM

Thanks Dan.

Dannihilator 02-24-13 10:01 PM

No prob.

lmariach 02-24-13 10:30 PM

My bad, didn't know about that thread.

Scrodzilla 02-24-13 10:33 PM

It's mentioned in the very first post of this thread.

Something with RiBMo (so far my favorite tire, 0 flats for 2 year old tires) level protection but rolls faster. Comfort can be a factor, but not necessary.

Hey Scrod, quick question about my chain line. It's 5mm off being straight (the chain lies straight between the cog and the dropout, not between the cog and the spokes), is that really bad? I've got a pake rum runner with novatec track hubs and omniums. There's not a lot of room between the chainring/spider and frame. Halp?

Not scrod, but did you make sure you installed a spacer (probably 2.5mm) on the non-drive side between your GXP cup and your BB shell?

First of all, you're right. You're not me. If you could refrain from answeing quesions in my thread - especially ones I've already addressed - that would be great.

Secondly, you're not supposed to use spacers on the GXP BB that comes with Omniums because it will prevent the non-drive side arm from bottoming out on the spindle, as it was designed to do when properly installed. I don't know why people insist on telling everyone to use spacers.

The chainline is not even close without a spacer on the NDS, at least in my case. I have a 68mm bottom bracket shell and I've used two different GXP bottom brackets with the same result.

If I am spreading misinformation I am sorry. but this is the setup that works for me. I am not the official SRAM messenger.

EDIT: FWIW I am using the 2012 Omniums.

Another edit: Also, I acknowledge at this point that the reason this thread exists is so that people can get your opinion (and yours alone) on their issues. This issue doesn't seem to be cut and dry so I thought I would chime in. I'm done now, so carry on. Once spring starts and I get a reason to tear everything down and clean it out, I'll try again without spacers and see what it looks like.

Scrodzilla 02-25-13 11:30 AM

It doesn't matter what year your Omniums are. You're not supposed to use spacers because the included BB was designed for use on a 68mm shell and the spindle attached to the drive side arm's length reflects that. Unless you have a way of magically lengthening the spindle to compensate for the 2.5mm spacer, you can't properly install the non-drive side arm when using a spacer on either side.

Also, would you mind telling me how putting a spacer on the NDS would possibly have any effect on chainline? Here in the dimension where I live, it wouldn't.

FixedDriveJess 02-25-13 11:39 AM

What chain would you recommend most for street use?

Scrodzilla 02-25-13 11:40 AM

That's pretty vague. Two of my favorites are the KMC D-101 and K-710SL. Izumi Eco chains are actually really good too.

This makes sense to me, I agree. It's been a while since I've looked at it - I'll revisit it sometime soon and double check.

Scrodzilla 02-25-13 04:38 PM

That's funny, I was going to suggest Ribmos. If you keep them inflated a wee bit over recommended PSI, they roll pretty damn fast.

Durano Plus is also a really good choice. Not as meaty as Ribmos but extremely durable.

calv 02-25-13 04:40 PM

Forget it, I won't **** with whats not broken.

Mumonkan 02-25-13 04:49 PM

I love my durano plus, theyre fast as **** and havent been stabbed yet

Do Durano's run big? Im trying to find a quality 28c tire for my rear wheel; preferably light and smooth riding.

GENESTARWIND 02-25-13 11:16 PM

hi scrod did you miss me?

anyways, your thoughts on hutchinson tires? ive got a set of fusion 3's is got a deal on and so far i love them, smooth comfy and roll pretty well. Just curious if youve had experience with them and likes or dislikes, durability ect....

ive read some good reviews throughout the web but would like to here what you think.

This.

Is it better to have a large front gear with a bigger rear than to have the same ratio but with smaller gears? E.g. 53/13 = 4.08/1 or 44/11 = 4/1
