I think the idea behind the shaft is to have tha same size ring on both sides (up and down) of the pivot. In this situation you don't get the extra chain extention from the bottom part so chain does not extend at all. With an idler (i'm having this setup on my bike*) you get no chain extent on the top side, but having the chainring and/or guide lower, the chain grows from the botom. In my case, the total chain extent w/o the idler is 45mm with it it's cut to 20mm. With a shaft design it would be 0mm. So an idler will kill most of the pedal bob, but it'll not remove the feedback in it's full like a jackshaft would.

As for the weight... that frame is great and lite, but with an idler setup you won't need the excentric bb, so there's the extra weight in that case. So if you have the excentric bb it's beter to run the shaft, if not you could end up better with an idler setup. The advantage of the smaler ring is still there for the shafted bike. :monkey:

*i'm not running this frame or the Race link, just another high pivot bike :)

yeah, that's a comparibly low idler though. you don't have that much extra chain. if you had something with a much higher pivot, it would be a much bigger pain. something like the old canfield comes to mind.

i take exception with these comments, but we've been through that quagmire before.

i think one of the newer benefits of the jackshaft system with the current super low bb heights, is the huge ground clearance with the tiny ring. bashguards take a beating on conventional newschool lowriders. probably the cleanest way to deal with a high pivot too - nice tight chainline / ability to run a short cage for additional clearance. it just looks sexy as well.

CCDB next to a rusty chain, really just doesn't sit well. You'd think they could find a KMC X9 (or 710) SL Ti-N or something blingy to throw on for the photo shoot.

Actually it’s a brand spanking new KMC chain and that isn't rust. It's Bootleg Canyon’s lovely red dust clinging to the goopy grease that the chain is covered with when shipped. It’s really hard to get all that grease off, even with an acetone bath, so as a result you end up with a dusty chain until the grease wears off in a few weeks.

Not really a "photo shoot" either. Just a quick shot taken at the shop to post on our Torch page for anyone interested in the various shock options we're looking forward to offering on the production bikes.

Not quite. The Race Link uses a 17T cog on the LHD and a 23T on the drive side.

The Race link has almost 3" of rearward travel. Coupled with the higher then average pivot an Idler just wasn't ideal. I think a lower pivot is more conducive to an idler. Like I said, it was an easy and cheap experiment and once I did it, I didn't have to keep wondering if it would be better.

An idler would definitely be lighter if the bike was designed for it. Just not a light weight conversion for the Race Link. I guess my main point was, that the jack shaft seems to work much better on the Race Link and the Silencer because of the really high pivot makes it tough for the idler to do the job. With the jackshaft, chain growth is zero. The idler only minimizes it.

When you consider that you don't have to have a chainguide, bashguard and can run a smaller chainring. I would think the weight difference between a jackshaft and an idler would be minimal.

One other point. Sandwich was right on the money again, regarding the Canfield. I had an F1 and dropping the chain was a regular occurrence, and not just me. 2006 was the last year I had it. There were 2 other F1's at Angel Fire that year. So a total of 3 of us. We all lost are chains multiple times on that course. And 2 of us lost our chains on our race run. I lost mine, 1 minute into my run. I think is was a 6 minute course that year. I did the entire rest of the course with no chain. Still managed to get a 3rd place finish.:happydance:

Like the Race Link, the Canfield had a LOT of rearward travel and I think the idler just wasn't up to the task. The Jackshaft drive on the other hand is the most reliable drive system I have ever ran. You drop a chain if you break the chain and that's about it.

Well I knew you would. LOL. :D

I don't mean to always be a downer on the gearbox. It's a great idea. Heck, I was one of the first to own one. I was a notorious derailleur destroyer. When they eventually work out the quirks (none of them are insurmountable) it'll be a great advancement. Right now, it's unfortunately still in the boot strap and duct tape stage, where it has unfortunately sat for close to 8 years now. Not much has changed I'm afraid.

Oddly enough, I rarely bust a derailleur nowadays. maybe one a year and I ride all over Colorado. The terrain out here is brutal on 'em. Once I got tired of paying for new ones. I finally just started really thinking about every line I picked and the impact (no pun intended) it would have on my derailleur. Now it just automatic I guess. I sorta subconsciously pick derailleur safe lines, without really thinking about it.

Just to be clear what i wanted to say (up/down part) is that you don't have a big ring under the drive side ring/idler to pull the mech side of the chain, like with an idler - not that you should run the same ring left and right. I'm well aware with the benefits from the JackShaft system ;) and i know that running different rings on both sides is part of those benefits :rolleyes:

OK...... I guess I'm not sure what point you were originally trying to make when you replied to my earlier post.

Perhaps you thought I was arguing that the jackshaft is lighter or better then and Idler in general. My comment was in response to JonKrank's earlier comment and based solely in regards to converting the Brooklyn Race Link (or a Superco) to an idler and not any other designs (although I believe the Canfield F1 would benefit from a Jack Shaft).

Hope that clears it up.

I didn't see the 38lbs part.I work with steel and aluminum,and thats pretty impressive weight .How does the pivot location feel or react?I just got a 224 and am still getting used to the squat in corners.

Depending how Superco have set up the floater, it shouldn't squat at all, or possibly just a tad to counter act fork dive. It wouldn't have a floater if they wanted lots of squat
It basically won't squat or lock out at all when pedaling.

Way to mix your personal guesses on braking and pedaling performance into a confusing little package there! :clapping:

What was so hard to understand?
It has a floating brake. The main objective of a floating brake is to get rid of Brake squat/lock out. They may have designed a touch of it into the design though. But even if they did, it'd be a lot less than without a floater.
and
It has a jackshaft, to eliminate chain growth which causes pedal induced lock out, pedal kick back, and pedaling induced suspension extension.
If you don't get that. Look at the bike, picture a normal chain set up(no jack shaft). The chain would want to pull the rear wheel in(down)when pedaling, and the swingarm when the suspension compressed, would pull the chain, making the cranks pedal backwards.

With the brakes, without a floater, it's as if the wheel is seized solid, and your trying to rotate it with your hands, the force of you rotating it will make the suspension compress(wheel go up).

Late summer/early fall is the target. I wish we had a specific date to give you but our original production schedule is being modified to accomodate the shaky economy. Additionally, we remain hopeful this re-scheduling will help us avoid having to take deposits until production is completed.

T, I'm guessing its also too soon to give out specific info in regards to price? Will we get this info when the availability date is released?

thanks T. is there going to be a test ridership program so we can get on one faster? :brows: I promise to provide weekly feedback and plaster stickers all over my helmet, face, car, and girlfriend

You are correct Jon, still too soon to be able to nail down the price.

We'll be offering test rides at a few resorts throughout the Rocky Mountains and Northeast this summer. Details are still being sorted and we'll post it up in the Torch once we have them set.

We have sticker kits for sale that would look great on your face Sandrew and really nice ladies tee's for your sweetie pie. The t-shirt is much softer than the decals and won't leave a red mark once it's removed.

that's a great mod. my kid is about ready for a pedally bike, but most 12" bikes are still tight in standover. a 12" bike modeled after the dirtjumpers would be sick (and of course ridiculously expensive for what it is).

DO WANT...after riding my sunday around for a couple of lift days, I'm really starting to miss the construction and ride quality of my old link bike. That thing just looks better and better....patience...
