Well done to ALL posters
It soon became useful and entertaining. There are regular posters, people who add useful info occasionally and plenty more who drop by to watch. That's fine. If you want to add news/comments it's easy to register and become a member.
RULES No personal insults. No swearing.
I know there have been some predecessors (Schlumpf etc), but the gear ratio picture looks quite impressive - equally spaced 18 gears with better range than a Rohloff - 2.7 kilos is a kilo heavier and it's not going to win any beauty awards but it seems pretty impressive…

If I'm not much mistaken that's essentially a miniature motorcycle gearbox. Lovely idea.
It says it's 3x6 so I wondered too if it was 3 6 speed motorcycle sequential gearboxes - no technical data there really apart from ratios and no pics of the shifter so I'm just guessing…
(edit: shifter is Rohloff rotating grip style - possibly indicating sequential)
PinkBike has done one of the more in-depth reviews of the Pinion gearbox:

Just about everyone likes it, and internal drag is comparable with derailleurs. The shifter is dual cable, so like a Rohloff, and ratios are engaged sequentially by pawls projecting (or not) from the two shafts. The only gripe is that the cables enter from the top at the front end, so may be more prone than a Rohloff to accumulate crud thrown from the wheel.
thanks Arrelcat - neat system….
I understand from a touring bike review on idworx-bikes.de that a 12-speed and two 9-speed gearboxes from Pinion are being introduced too, to make the technology more accessible to urban cyclists (rather than Pinion's target demographic of hardened tourers and mountain bikers).
This looks like a winter option for commuters who want maintainance free bikes with only the odd (annual??) belt change done at a LBS?
Looks neat, but with the gearing being at the front end, doesn't it spin up the chain/belt drive to quite a high speed?
What's that? You want the ultimate commuter and you've found a buyer for that surplus kidney?

They're very coy about the price in that 'if you need to ask you can't afford it' way. €4,896.40 for the model I built in the Konfigurator.
But I'll bet it was lovely...
