How the **** am I going to put that in me frame?

Looks most interesting.

Wonder who'll be the frame maker to adopt it?

Please let it be amazing and acceptable weight and bought out by Shimano and released!

that looks the bolx… much smaller that other products out there…

Looks good, but I'm suspicious of anything that claims to be that good but has so little detailed information on the website.

Rohloff have a minimum gear ratio to avoid putting too much torque through the hub.
If this has got the gearbox directly on the cranks, it will need to be stronger. With more gears as well, it's unlikely to be lighter.

Why no pictures of the left hand side ?
Why no pictures of the shifter ? Looks like a Rohloff style twistgrip & two cables in that picture above.

I think this is thefirst bike to feature it:

Interesting.

its very different from an alfine or rohloff as its a normal gearbox like a motorcycle one but with three shafts rather than a epicyclic like an old auto car. should make it more efficient and lower loadings.

Looks good

looks ace

but you will have to have some sort of derailer or chain tensioner on for FS bikes though

Wow, now I really like that. The Endorfin with it fitted looks ace. Will be really interesting to find out some details.

What does appeal is they claim a 634% gear range with even 11.5% ratio steps. My rohloff has 526% range over 14 gears with 13.6% steps. The gaps have always seemed just a bit too big, but this would seem to reduce that. And sort out the weight ballance issue at the same time.

I wonder what it’ll cost!!

You’re right,you know.
Is it just the perspective, or is that crank not going to turn ? 😕

If you click on “Original Document” in the link above, there’s a load of exploded diagrams on the last few pages.
Looks to be a mixture of conventional and epicyclic gears.

It will probably cost a bit though.

was talking to some german journos earlier this year about nicolai and suntours gboxx program, it seems that getting these types of boxes mass produced to get the costs down is a major obstacle so it ens up being a german “engineered” product with the costs to match

Braking via the chain? Doesn’t sound good!

634% gear ratio? I doubt I’d be using the extremes of that at all – one end would be for climbing vertical walls and the other for spinning pedals very slowly down a gert big hill. Fewer gears and lighter for the win.

Looks very neat though.

MidlandTrailquestsGraham raised the most interesting point, that the gear teeth will have to take twice the load of those in hub gears, which given the size of the unit might me there are some pretty small margins for error there.

Good point – if it’s the same as a motorbike gearbox, it’ll need a clutch no?

No need for a clutch, just back off the pedal pressure slightly when shifting, same as a Rohloff I would imagine.

Incidently, did anyone else spot the Rohloff dropout on that Endorfin ?
That raises the interesting possibility of an 18 x 14, or 252 speed transmission. 😀

No, you can shift a motorbike without the clutch, its doesnt do it any good nececeraly, but it does work.

My Rohloff is fine @ 526% – just wish they’d hurry up & use some Ti parts to get the weight down before they lose the battle to Shimano.
But mass centralisation is the way to go with maybe 12-14 gears & 550% range & get under the weight of an XT drive system.

Weight is not such an issue when it’s at the centre of the bike and set low in the frame.
The rear wheel will be nice and light and that counts for a lot.
