dont think it is necessary, get a 1X10 or 1X9 and man up. looks super complicated and weak. solving a problem that is already solved. i run a 34 on the front and a 11-32 on the back and ill make it up anything a guy on a double or triple will

Got a 1x10 setup with a 34 chainring and 36-11 cassette... Which essentially gives me a granny ring ration with a normal chainguide and only 1 mech to go wrong!

Agreed Joe, a 34 up front with a 11-32 in back is the way to go. Simplified and affective.

I run 36t front and 11~34 back on my 22lb Blizzard and it serves me well 99.9%. Those 0.01% on very step and strenuous slopes I usually just 'walk and push'. Simple!

when i go out on my bike i dont want to go and take my bike for a walk. i like the challange of getting up gnarly steep climes so the granny ring stays. the G ring lets you spin a smoother cadence giving you 'more grip' (basically).

or get a hammerschmidt... i think it might work better and not be nearly as fragile

hell yeah to all the above. i run a 1x 9 set up, 36 front 34 rear, never found a hill yet to beat me. i used to race xc about 10 years ago and raced it flat pedals, 130mm manitou sherman, and 38 front cog 32 rear. 1x9. was only guy on hill with a chain device, a few podiums and 4th place overall in series tells me that gears are very overrated.

@riccichang2004 - dont every "walk or push" !!!! look at todays POD, that guy is on an all mountain ride and ripping! your gearing set up is not whats keeping you from destroying the steeps.

Would have been nice to have seen a solid works motion study, would have really helped people understand it.

Agreed- I have no idea what this thing is supposed to do or why I would ever need it.

Did you not watch the video? It makes it pretty obvious what it's meant to do

I fully understand what it does, but how it worked

of course I watched the video...still don't get it.

It's just a dual ring chain device but whereas normal ones rely on the front mech to help hold the chain on at the top and a static roller on the bottom, a proper guide is used which is more effective at keeping the chain in place. This has to be able to move in and out to be able to shift between the granny and the bigger ring which is done by the little cams. What's not to get?

Maybe a little too complicated, but I think its a well thought out innovative idea.

deakmaster (May 8, 2012 at 10:21)

i agree. the parts are fragile. maybe get some extra plastic protection for them. i doubt any downhiller would want two front chainrings, an extra shifter to worry about and that clunky thing PLUS a bashgaurd, which is too much weight and shit to worry about. just roll with the bashgaurd and guide. eventually you will find what gearing you like and just run one front chainring.

The first video showcases Mr. Montgomery's severe lack of knowledge regarding the cycling sport. If he thinks that this guide would be better marketed towards DH riders than XC, then he's clearly got no idea what its intended use is. Mike you're a good rider, but leave the critical thinking to people in the industry please.

What if you just used the same mechanical deign that moves a front derailleur back and forth, but with two of them, the one on the bottom pushing down and out instead of up and out? It would need to be two pieces but it would achieve the same thing achieving tech that already is used.
This is the first concept that got a fair shake I thought.

Logical in intregration-type-progression, but alot of noise potential. DRS systems are pretty much flawless where they're at outside of not having the half-bash be %100 reliable.
Gets my Vote for having good-intent.

So, where is the shiftcable attached?
Or, how does it shift?
That needs some explanation...

rffr (May 8, 2012 at 15:40)

It doesn't shift. It's meant to be used with a front der.

BeantownKiwi (May 8, 2012 at 16:11)

Nope, no front derraileur required - this replaces the front derr. Still, I wasn't entirely sure where the cable attaches either. That was the one part of this submission that lacked detail.

rffr (May 9, 2012 at 16:36)

Uhhh, the video made it seemed as this worked with the front der, and so does the article. Not sure how a chainguide that actuates from the bottom first is going to switch gears....

Is the money they list at the end of the show prize money, money towards developing the project, scholarship money, or just theoretical "points" money? I haven't watched every video or read every post. So sorry if it's already been explained.

It is approximate prices as to what it would cost to bring that product to life. How much more time needs to spent on the designing by a professional so that it could be a working prototype, possibly getting is rapid printed/prototyped, what the materials would be to make the first version of it and what the machining/assembly costs would be.

dhpierce FL (May 8, 2012 at 18:15)

I love it, lets remember that this is a ruff draft.... there needs to be a lot more detail that goes into it but i could work really well. Further more, i strongly believe that if the concept of rear deraillers were subject to this scrutiny like it was a new idea... almost all the same post would apply, for example it looks flimsy, it will cost a lot to make, were does the cable go, just another part to brake lol

Anyone boasting that they can climb any hill with a 34 front and 11 34 is full of it, there are plenty of super steep climbs that you will never make it up with anything other than a 22 or24 front and 11 34 rear, hey joe swann I wiil climb up hills with a 24 11 34 that you would struggle to walk up.

2.5 yrs on my uzzi with blackspire stinger with double ring setup. don't remember the last time i dropped a chain.

seraph (May 8, 2012 at 10:06)

Yeah that's what I was wondering about really. The guy says "if you've ever dropped a chain with a double setup" but hey guy, there are these things called "double guides" and they work great. I just got the new E.13 TRS+ Dual and it's seriously the smoothest dual ring guide I have ever run. Quietest too.

KAHL1 (May 8, 2012 at 18:49)

Why not just use any of the double ring chain guides and a derailleur?

While the concept might be simple and solid, the actual product seems to be neither of those things unfortunately.

either/or both work and are already on the market, why spend 27,000+ to work out something that has already been worked out, does it better, and is already on the market
