build a 420-speed bicycle...
    #5561212 - 04/27/06 12:08 AM (17 years, 9 months ago)

it could be done..if the 14-speed internal hub below could be hooked up to a 10-speed cassette and a 3-ring crankset ..



the hard part would be to marry it to a deraileur system (and still have it fit into the frame).. the online documentation doesnt say if its possible..let alone how to do it...but im a bit curious if anyone has tried this...

The thing that comes to my mind first is the horrible amount of friction you'd wind up having to overcome. It would be pretty tiring, especially for a lazy stoner :tongue:

the hub is 96% efficient..at least according to the vendor..so theres not that much friction...in either case..stoners (both lazy and otherwise) are the reason theres 420 gears and not 419 or 421...

how much would that damn thing weigh?!?! Pedaling, especially into the wind, would be hard as hell. It'd be cool though.

according to the online documentation..the hub weighs 1700-1800g (and costs 768-970 euro) depending on which model..so you could still make something thats pretty light with a carbon or titanium frame and high-end components (ie if you attach the $1000 hub to a $3000 bike)...the price..however..is relative..since you get 1400% more gears for only 33% extra...

but even if you could come up with the cash..and manage to attach the casette to the hub..there would likely still be some nasty alignment issues to overcome...and then theres the nuissance of overlapping gear ratios...

Sounds like this is a frivolatry suited only for the wealthy and/or the highly eccentric.

Fun, but damned expensive.

i fully agree that its an absolutely rediculous price to pay for one hub...the shimano nexus(r) inter-8- speed hub is a much better value at $200 and is a bit smaller and lighter than the rohloff...so if your willing to settle for 240 gears..then it might be possible to bring the total cost down to within $2000...

hm, that shimano looks really nice. I currently have a (standard?) Shimano 105. I could go from 27 gears to 240, interesting. Is the $200 just for the derailleur system or does it include chainwheels and whatnot?

actually..the newer shimano 105s have 30 gears..if yours has 27..then you could get 216 with an 8-speed hub..

The rohloff is worth every penny in my opinion. a friend has one on his DH bike, which i get to ride often. the weight is somewhat noticable in the back, as is the case with the inter8 (which i own personally) and the 14 gear spread is plenty for any situation. working on them is a breeze, as the shifting is indexed inside the hub, so there is no cable adjustments to be made, and they basically run forever with only changes to the oil bath needing to be made. for all these reasons, and the disc brake mount, the rohloff is the most ultimate multispeed drive train out there. plus the price aint that bad if you compare it with buying:

xtr front/rear derallieurs

front chainrings

8/9spd rear hub/cassette

front/rear shifters.

all that shit adds up quick!

really though, i have had excellent luck with my inter8, which also has an excellent spread of gears as well, and when shimano drops one with a disc brake mount, it will be a HOT fucking item.

i know that there are many bikes with disk brakes, and i think that i saw one with rear abs once...

yeah, drum brakes have been done.

both the rohloff and the inter8 can be fitted with a roller cam brake, which is somewhat similar to a drum. the perfourmance is poor in my opinion, but if you are planning on just touring/commuting with one, it'll work just fine.

for most apps though, i find rim brakes (v brakes) to be plenty powerful in a range of conditions, usually out-perfourming mechanical disks as well. i will say hydraulic disk brakes are amazing stoppers though. my dual suspension mtb has them, and they stop unlike anything i have ever felt on a pedal bike.

I've generally been taught that drum brakes are inferior to disk brakes. I wouldn't actually choose drum brakes over disk brakes on any vehicle unless there was some sort of compelling reason (such as if they were much cheaper).

I was just curious if they had been done, I didn't have any interest in doing it myself though.

To be brutally honest, I never even learned how to ride a freaking bike :lol:

I agree. I actually rode a few bikes with disc brakes before choosing my current bike, which has rim brakes. I just felt uncomfortable with the disc brakes, not to mention some of the stories I heard and read about them.

Konnrade: you should learn if you have the time, it really can be a lot of fun and a great release.
