[Closed] Pinion gearboxes

How does that work?

Edit: Note to self, Google it!!
http://pinion.eu/en/discover-pinion/pinion-p1-18/

I've been loosly following these, any more news on availability?

Hmmm, to Pinion or XX1 ❓

Back in the real world I'll stick with 9spd until the stuff I have dies 😈

Someone on this 'ere forum has one. Can't remember who.

interesting chain-tensioner. I'd have thought a single pulley like a chain-guide/device would have been neater.

Edit - is it you ianpinder? Is that yours?

Mine should be with me the end of this month. The one you see in the picture is pretty much the first production customer nicolai one.

The chain tensioner is located there because the chain is more secure on the front ring and saves you having to run a chain guide. They found on the proto they sometimes dropped the chain on the front when used with a rohlf tensioner, so they designed this one.

IMO doesn't look quite as clean as a rear chain tensioner, but never the less, function over form

There are very few bike companies making the compatible frames, I only know of Nicolai but there are a few others, if you order one now you might be lucky by Christmas.

If you are interested speak to Nicolai UK

Does that weigh a ton?

About a lb heavier then a regular 2x10 set up

I'm struggling to see how the guide works. Does the chain go over the top of the upper pulley and round the bottom of the lower thereby pulling the whole assembly rearward? Otherwise its surely going to last about five minutes until you ****t it on a rock/root.

Ah good to know there not far off! I hope you get yours soon ianpinder 🙂

You will have to post up a review!
I Won't be getting one this year but will see how how things stand next year.

How it looks built up

What's needed is a stronger version of the YESS ETR/B, designed to cope with the change in chain-length of the suspension.

Or even better, a bike designed to give minimal chain-growth when used with the Pinion.

Although, that does look bloody fantastic!

Dare I ask how much you've paid for frame and gearbox?

Does the chain go over the top of the upper pulley and round the bottom of the lower thereby pulling the whole assembly rearward?

Yep, like a rear mech but in reverse.

Highly desirable system.
Is there a temptation to put a belt drive on it? Or change the chain ring following the SRAM profile for their X1?
Better start saving ... rate of saving versus price reduction looks like I will get one in 2016.

Well, it's £3150 for the am frame with pinion cranks and shifter.

Sounds a lot, but once you add up the cost of a drivetrain (my last nicolai that was £1000) then it works out about £300 more expensive.

My frame is not a am pinion, it's a 29er ac pinion with custom geometry!

Is there a temptation to put a belt drive on it

Its something I've thought a lot about 🙂

At the moment, the only way for a belt-drive on a full-sus frame is by having a single pivot co-axial with the BB. Like a Kona A. Like [url= http://www.flickr.com/photos/ir_bandito/7250968566/in/set-72157630866523592 ]my Kona A[/url] for example 🙂
To work with th ePinion, you'd need a single pivot coaxial with the BB and the final drive, which gets massivly complicated. Would be simpler if the Pinion final drive wasn't co-axial with the BB, which I'm sure wouldn't be too hard for them to design. I might even have a go myself.

I'm going to see if they can do a gates, pinion ht 29er as a touring bike. Going across africa I went through 7 chains and four cassettes in 4 months!.

I asked Pinion about doing a belt-drive when they first came out. They said they hadn't considered it, but since their work with Nicolai I'd be amazed if they don't.

Did you not consider a belt-drive Rohloff?

Well, I've not considered either yet properly, obviously I'm going to test the pinion, if I like it then I will move ahead looking at belt drive options.....

That built up one looks lovely, always had a hankering for a nicolai. Look forward to seeing yours as it sounds like my perfect bike.

I'm already saving for the Mk2 🙂

Nothing wrong with it as it is, but by the time I can affort it I'm presuming they'll be well into th next development cycle.

They are talking about developing the shifter, maybe to electronic shifting to get rid of the gripshifter!

If they're running a front tensioner you'd think they'd machine a drive side dropout without a mech hanger

Hopefully in time they will....

Our first one landed at the end of last week and is with Brixton Cycles being built up for a customer - Argon FR 26 hardtail.

Pinion *are* Gates compatible - and have said so since their launch at Eurobike last year (and the Argon Pinion is built as standard with a Gates compatible rear triangle)

Looks amazing - will be interesting to see how the total weight works out. The Argon frame with box and cranks fitted came in at 5.78kg. Large, anodised. The Argon FR isn't a light frame to start with however!

Recent new arrival with a friend of mine.

33lbs with air shocks (nearly as pictured)... I plan to get a shottie sometime

that's very nice looking.

Simon - have you seen a Gates Pinion bike yet? Has anyone actually built one?

wow the future has arrived

i wonder if shimano are developing one?

the gear box itself fantastic. just a shame it has a grip shift shifter and even more of a shame it has to go on a gopping nicolai frame.

Here's one with a Gates drive on it:

http://www.mi-tech.de/Tyke%20Pinion%20P1.html

Has to have a grip-shifter as it works similar to the Rohloff, ie pulls both cables to change up or down, and with all those gears to get through, that's a lot of cable.

Nice find packer... that deserves it's own picture... ooof!

The Mi:Tech Pinion bikes have been discussed on here before if you want to know more about them:

http://singletrackworld.com/forum/topic/18-speed-mtb-gearboxes/page/3

Anyone seen one with a bb pivot yet?

There is another Pinion plus Gates bike on the horizon from Koga, at least that's how the picture on the Gates blog looks like. "Koga World Traveller 29"

http://blog.carbondrivesystems.com/?p=4001

There are some very nice bikes on there

And after around 14 months of planning, mine has arrived!

Very nice! Can't wait to see it built up...

Lovin the green.

Yeah that green looks good

Very interested in hearing your thoughts on riding it

I'd love to see a back to back between this and the effi-gear box

Ian - you built it up yet? Keen to hear your thoughts once you've ridden it a few times.

Sweet, I'd love to follow the same road your taking. Total logical beauty.

So then Ian, wossit like?
