Apologies if this has been posted already- I've been away from RM for a few months, but how's this for interesting?-
The first (?) Pinion geared DH bike?

(At least I think it is!)

From the guys that brought you this;

Comes a new 4th gen DH gearbox bike;

Whilst this image doesn't show much, a CAD screen shot from their website clearly shows a Pinion gearbox;

I can't wait to hear more info!

I am one those guys! As far as we are aware it's the first pinion DH bike, we are waiting on our first boxes and still have a fair amount of moulding work to do but it's slowly happening! Thanks for the interest in it - we can't wait to see it in the flesh. Lot's of work put into this one...

Is this where we're talking about the new full carbon v10 now? I'm confused.

We've already established it looks flexy and will buck you.

 

[sethimus]

does it ride light?

I'll pay that. Anything to get rid of Moar flexy rootbeer.

Yes, I believe this is the official V10C tech/tuning thread.

I'll start - damn that's a light frame!

All that testing, design and manufacturing prowess and still, STILL a F***king derailleur!!


Too soon?

 

[boogenman]

Where can I get a TLD race kit with the Wonder Bread bag design on it?

Kinda like this?

At least put it in quotes instead of plagiarising it jesus....

Ask this guy

 

[jeremy_2640]

Hey guys, it's been a while since I've posted here, thought it'd be nice to get the gearbox thread back up the list!

We've been working flat out on getting our bike together - if you want to see some pictures and info on the build jump on our facebook and like it (links in my signature). Help spread the word, we're super excited about this new bike!?!

Zerode Carbon AM Bike..

wow, this thread is almost 9 years old now. curious the current state of gearbox development (or lack thereof); i had thought we'd have come further, or perhaps one of the big players would have come out with a light(er) weight high performance gear hub. that said, derailleur systems have come a long way; clutches and tucked away designs in conjunction with drop-resistant chainrings and huge spread cassettes have certainly reinforced their viability. my newfangled derailleurs work pretty great.

that said, my lahar is now into it's 7th year; soldering on flawlessly as always...

 

[Kntr]

Ive had my Zerode 2 years with only 1 missed shift because I didn't have the cable adjusted correctly. I absolutely love this thing. I haven't done a single thing to the bike. Love it!

The best bet would be a Honda esque system that basically allows unlimited gear range so the AM crowd can have a any range via a trigger shifter. Although the 600%+ that the Pinion provides is good. I suspect the UCI would get its panties in a bunch if a Downhill bike showed up with an unlimited gear range. But if you could find a way to limit the gears used to say 10. Then be able to move it around for a certain track that would be pretty cool. BTW I use 3 gears on the Zerode 4 if I am feeling frisky.

 

[demo 9]

Are there any internally geared hubs besides an alfine? Anybody know?

True, I thought the big boys have jumped in by now. Clutched mech and weight weeny fad has given them new lease on Mech salability. I still think the centralized weight, shifting any time, toughness, reliability, and better ground clearance are huge reasons for gearbox over mechs.
Wish I'd had kept my Lahar, I'd have loved to have got a cromo shorter swingarm made for it to lower the BB and shorten the rear.

Pretty sure the UCI banned the CTV Honda, and made a 9 speed ruling. Not sure what's happened to that now 10 speeds here.

Rohloff, Sram also make some, Sturmey Archer, Nuvinci.

 

[konastab01]

Damn 9 years. My Lahar hangs in my garage not doing anything these days!

 

[xy9ine]

i'd like to do exactly this at some point. perhaps lose the floater at the same time. alas, i'm in allmountainy enduro mode these days, so the sled doesn't get used enough to make that a priority. that said, the geometry is still surprisingly current as is. what i thought was ridiculously slack back then is standard fare right now. bb is a bit higher, yes (close to v10 height, so not too far off), and stays certainly longer, but i'm used to them now. running the thing short shocked (~8" travel) drops things a little, and works quite nicely.

pretty sure this thing will still be viable at 10 yrs. pretty rad.

konastab - the bike still intact? replaced with another dh rig? curious where the rest of them ended up. where are you?

I can recall people on here saying they were way too slack. Bagging Carbon, press fit BBs and headsets.
Short shocking it would make the stays even longer though. I guess at ride height they'd be much the shame. New linkage to make it 8"s would be easier. Didn't you get some custom linkage plates before it all went pear shaped? No floater has it's pros for sure. Getting a Horst Link style steel swingarm wouldn't cost you very much. You could short shock it with new front mounting plates and main link and swingarm as a 6" bike. Would be light enough with an air shock. Sick.

 

[xy9ine]

interesting aside - i actually cracked my first frame (small crack near the headtube caused by a big, dumb nose case). aaron built me a new extra carbon fortified stupid-proof front end, and, knowing the weight weenie i was, spun custom plastic bb spacers to go with a lighter set of press in bb bearings than the standard stuff. with the new front end he sent newly whittled lighter shock plates as well (i think they were standard on the later frames). and he did all this for no extra charge, with a 3 week turnaround. alas, later customers' experiences were not so rosy.

other interesting aside - my old frame was patched up and ended up racing jr worlds at ft bill that year (don't recall who the jr rider was):

 

[jonKranked]

Pretty sure the UCI banned the CTV Honda, and made a 9 speed ruling. Not sure what's happened to that now 10 speeds here.

the last iteration of the honda was basically a DIAB. so i kinda doubt that the UCI banned it.

doubt there's a 9 spd ruling. most guys run the latest which is 10spd, plus wasn't it ft bill this year that gwin and a few others were rocking custom 7spd cassettes?

Ahh yeah. The last interaction of the Honda was, because the UCI Banned the CVT is the whole point. Not sure if it's true.
9 speed max was the rule I heard, not minimum. Surely 10speeds been raced by now. Or does everyone know it's crap for DH?

 

[Percy]

I think that Jnr ride was Dave Scandrett, but don't quote me on that, I have been hit in the head since then...

Confirmed- spent many hours washing/prepping NZ bikes that week.

 

[konastab01]

One things for sure if he ever resurfaces he owes me a another one, As he was meant to making the M10's and ****ed me on that one!

He mad some different linkage plates for the later ones.

I'd also like to give me a bash at being a enduro bike too, but it all money and considering I've been riding pretty road for the last year Its been really hard to get out and riding anything else! Espically when you gotta drive everywhere.

 

[jonKranked]

story i heard was that Honda scrapped it because it was too complex for too little improvement.

don't know where you're hearing this stuff, but it ain't true. why would the UCI ban stock components for dh when in road biking they are mandatory?

 

[ianjenn]

I have all the MTBR magazines about the Honda. The first box was insane. It basically had infinite gears in it. It looks pretty damn complicated with all the cams and stuff. But damn its bad-ass looking.....

I can shoot pictures of the pages and load them on here.

yea, i'm pretty sure those are the ones i remember.

that would be sweet... do it!

here's the final iteration i mentioned, DiaB:

i think this might be one of the pages ian referred to:

xy9ine, is that an Öhlins shock in that RNF II?!?!?

showa. another major lust factor of that bike. fork too.

 

[ianjenn]

They started with Kayaba then went to Showa not sure when. I have the magazines it will be about 8-10 pages in total will try to load them at about 2000 by 1600 or so!

 

[jonKranked]

i did not know that. interesting. i think by the time they had the team in full swing they were on showa.

 

[Raingauge]

I think you can find the patents online as well.

[LMC]

I'm thinking they got the idea from a variable stroke engine. Funny how after all these years the gearbox still gets talked about.
