Checking clifcat website i think they dont make jackshaft bike anymorevitox said:clifcat and balfa made jackshaft bikes, there are more in europe too.
i think theyre called the holeshot and nouvau riche respectively.
oh and do a search for devinci big bang
Clifcat can still make them they're special ordered.rbx said:Checking clifcat website i think they dont make jackshaft bike anymore
Also looking for frames still in production,the gack seems ok, oh well seems that i am going to have to go with the BMW(not that is bad far from it but the price!!..ouch)
I keep reading and hearing that bikes with pulleys like balfas dont pedal well not because of bad suspension design,but of friction created by the pulley.ChrisRobin said:Clifcat can still make them they're special ordered.
I remember talking to Bill (Clifcat owner) about it a few years ago and he said to save weight he would sometimes put a pulley at the pivot to simulate a jackshaft. He said it felt just as good.
I don't see how there could be much less friction with a true jackshaft frame: You have your main bottom bracket at the bottom where your cranks are, with a chain driving the other chainring attached to the pivot (on the Clifcat bikes it was a second Profile bottom bracket in the pivot), which drives the chainring on the other side of the frame which drives the rear wheel.rbx said:I keep reading and hearing that bikes with pulleys like balfas dont pedal well not because of bad suspension design,but of friction created by the pulley.
I maybe way off

Hold on a sec...apparently there's been some e-rumours and e-speculation going around saying they're having trouble with the Nexus hub.rbx said:Totally forgot about the GT-It1 ok i think my problem is solved thanks for the help guys!
Drops to flat.skatetokil said:What on earth were they thinking?
Weird the last i heard from a thread on RM is that GT worked with shimano and solved the problem..but i am still confused??ChrisRobin said:Hold on a sec...apparently there's been some e-rumours and e-speculation going around saying they're having trouble with the Nexus hub.
I missed that part about Shimano fixing their problem.rbx said:Weird the last i heard from a thread on RM is that GT worked with shimano and solved the problem..but i am still confused??

How so?ChrisRobin said:Ahhh...that's because the Nucleon ST isn't a 100% true jackshaft bike.
The Nucleon ST doesn't have the Rolhoff hub in the pivot. It's just ahead of it. There's almost no chainstretch but there is still some...so that why I have to run that Rohloff tensioner.MikeD said:How so?
Well the Lahar isnt really a jackshaft bike! Which is what the thread is all aboot.MikeD said:A Nucleon owner posts in the thread and no mention of the Nucleon...?

Where's the Rohloff mounted, then? Right at the crank or something? I thought it used a primary/secondary drive configuration...my bad...Percy said:Well the Lahar isnt really a jackshaft bike! Which is what the thread is all aboot.
