This is questionable. For the right application (Dh / Enduro Racing) I think it makes more sense than other upgrades. For general trail riding I agree it's not where I'd put my money.Quote:

For all the doubters: go coast down a rough descent with no chain on and tell me your suspension doesn't feel noticeably better. I've seen plenty of armchair engineers run the numbers and say it shouldn't matter. But I've done it, and it does. I'm sure the O-chain doesn't make it as good as no chain at all, but if it didn't make a noticeable difference, you probably wouldn't see it on the majority of the bikes racing world cups.

And no, having a low engagement hub doesn't do the same thing, because when that hub does finally engage, it's a hard metal on metal stop, not a dense rubber-dampened stop. No one is saying that every casual rider needs to put an O-Chain on their bike. But it does provide a meaningful affect for bikes with certain suspension kinematics, riding steep, rough trails.Quote:

Eh, having done back to back tests with mine, I'd describe the feeling as whatever the hub feels like, plus extra slop/cush on top. A low engagement Roval pawl hub and the 9 degree setup felt pretty awful when you were trying to pedal out of corners, but felt ok with a Hydra. Hydra with 6 degree elastomer feels like a DT with 54t, except that you always get the play on first pedal stroke, and the end of the play is more muted.Quote:

On my Nomad 6, which has a few degrees less PK (especially deeper in travel), I'm not feeling the need to use it. I'm hanging onto it though, and might install it when I go up to the bike park in the summer.
Ah, yeah, I meant the difference in suspension performance would be almost imperceptible. Seems like the O-chain probably irons out any minor perceptible differences in kickback that you might feel between different hubs?Quote:

You guys see that new sram drivetrain?
The drivetrain has some improvements, at least in theory.Quote:

You're supposed to thread the brake hoses through your bar, then into the stem. Then they go through the top headset bearing and bend really tightly into the frame. Trust us, the Bicycle Marketing Professionals: it's better this way.Quote:

The 105 was a great economical option for a tight range cassette on a DH bike. I had a few on my early 2000's Rocky RM7.Quote:

Yeah I used to run 105s on my Super 8 and V10 back in the day often with a road cassette. Not only were they short cage but the spring was way stronger than MTB derailleurs. Those would only last a few days at whistler before the spring in the lower cage self destructed. The 105 seemed to last forever.
If you are anticipating the kickback it is less likely to throw you than if it is a surprise, no? That is, if you already have a good buffer in place with the O?Quote:

I haven't ridden a modern suspension bike where I felt like the kickback was throwing me. Maybe a little bit in weird situations where I hit a big compression in my easiest climbing gear, but that's not really my concern. It's mostly just that kickback interferes with the suspension movement and makes the suspension feel worse.Quote:

makes the stuff the fro-riders were doing pretty amazing, those were definatly the jump off of shit and break the frame days and apparetly BC riders broke more HW then anywhere else in NAQuote:

Think about size XS through XXL for the same model frames. You’re looking at wildly different handlebar heights relative to rider position.
Kids and short women are usually sitting upright and tall dudes are always hunched way over.

If only frame designers increased the stack height in larger sizes.Quote:
