I've heard 'some rumours' but I didn't know it was already World Cup race-ready.
I wonder if Karl Nicolai is involved in this B1 gearbox thing?
i've heard rumors of a lighter, fewer-geared (ie, more dh / freeride oriented) rohloff. it'd be great to see such a product come to fruition.springfish said:I heard from Tom at Rohloff that they have some BIG, top secret products coming out at years end. Maybe this inline with what he was talking about. The sooner the better (as long as it works).
Oh yeah, and rear deraileurs are soooooooo tough and reliable.Hrelp said:These gearbox ideas are great but the only thing keeping me from buying one is.... what if something goes wrong or needs adjustment you'd prob have to ship it out to get done which is killer downtime...
but at least they are universally available...TWISTED said:Oh yeah, and rear deraileurs are soooooooo tough and reliable.
If so why doesn't your bike have one?Toshi said:but at least they are universally available...
Ooooh, I saw that one coming...TWISTED said:If so why doesn't your bike have one?

You can run more complex rear suspension designs without a tensioner, it just requires a little thought on the manufacturers part. Take the Honda as an example, they have chain growth in their design yet don't run a deraileur type tensioner.dante said:nice concept, but... if you go to a gearbox design, is there any way to get around having a simple single-pivot (like the honda) or a linkage-driven sp bike like the b1? I can't get around thinking that you wouldn't be able to run any type of linkage with an extending chainline w/o some type of derailleur-like tension adjuster, and that just defeats the purpose... Will be interesting to see if they can overcome: weight, price, complex repairs and single pivot suspension problems.

Well the whole reason of having most of those linkages is for pedalling reasons, but with this you could make the bike pedal better than was easily possible before (without using a jackshaft or pulley, anyway). For example, you could tune such a bike (because the chainline is constant, and able to be placed pretty much wherever you like in relation to the axle/pivot axis) to pedal as well as any of the bikes currently on the market (eg DW-link, VPP)... IMO of course.dante said:nice concept, but... if you go to a gearbox design, is there any way to get around having a simple single-pivot (like the honda) or a linkage-driven sp bike like the b1?

You're dead right. I'm never going to buy a car in case that happens.Hrelp said:These gearbox ideas are great but the only thing keeping me from buying one is.... what if something goes wrong or needs adjustment you'd prob have to ship it out to get done which is killer downtime...

[hint] gearboxes are pretty reliable compared to derailleurs [/hint]
Thank You. I was thinking the same thing but didn't feel like typing the whole thing out. Basically high pivot =nice rearward and up axle path but problems with chain growth. Low pivot = poor axle path but no problem with chain growth. Links on the chainstay of a low pivot bike (fsr) can fix axle path problems.thaflyinfatman said:Well the whole reason of having most of those linkages is for pedalling reasons, but with this you could make the bike pedal better than was easily possible before (without using a jackshaft or pulley, anyway).

you tease, you know it will just start the speculation anyway without you....it begins....Nicolai-USA said:wait until this weekend, I may have a few surprises for you guys...
...tell us, tell us how many speedholes does it have ?Nicolai-USA said:wait until this weekend, I may have a few surprises for you guys...
So how often does your car's gearbox blow up? Work it out, then relate it into a per-kilometre/mile function, then tell me a derailleur has ever lasted you anywhere near that long. Before you go calling other people stupid, maybe you should have a look at how intelligent your own comments are... dumbass.Hrelp said:Thats great I wouldn't want to see someone as stupid as yourself on the road anyways. There are 50 tranmission specific shops for cars in my town and 0 qualified shops that could deal with a beone gearbox or rohloff. Imagine what life would be like if every transmission that broke had to be shipped off to get fixed.
