957 single speed????
« on: April 08, 2006, 06:06:45 am »
has anyone done it?
How about just leaving the rear cluster and using just one chain ring ? I'm thinking about it because my front derailieur it a BITCH to adjust as there are only millimeters between the scres and the swing arm!
Any help would be appreciated....maybe I just need a new front derailieur.... ?
thanks

You've got to ask yourself... How much do I need to shift the front end? Do my trails require that much range? Are 3 front chainrings necessary to get me down the trail, or are they just bling?

I really enjoy my single chain ring 856. (Picture under my old gallery "Will." See last pic in album.)

Took out lots of weight and complexity. Only one shifter! A lot less cable, too.

You'll need either a chain roller or abash guard to keep the chain on, but it's beautifully simple to ride. [smiley=beer.gif]

yes.

Jeff (on of the UK proflexers) had a singlespeed proflex 957 that he raced at the SS world cup in 2001 in Wales, UK.  I also used to use my 856 as a singlespeeder.  

great bikes and become ever-so-light with singlespeed.

Use a 32 front chainring on the middle spider and use spacers for a 16T on the rear in the middle as well to get a straight chain.  A surly singulator finishes the job to keep the chain tight.

You can always get your hands on a Rohloff hub...

I'm still waiting for someone to perfect the "Rohloff hub within the bottom bracket" concept. The hub is awesome, but it's too much unsprung weight for a full suspension frame... Having it in front would be perfect. I know it's been tried, but nobody has marketed it to the masses yet.

You think about something like that?



the g-boxx 1 is with the roloff
and the g-boxx 2 with a chain/gear device

kalle nicolai is about to get the shifting revolution started.

The only thing that has stopped me rebuilding the 855 as a single speed has been that I wasn't sure how a singulator would go in conjunction with rear wheel travel.

Now I've read this, I'm getting the shock sorted (just got a fox float RP'3 and am getting an adapter machined) and the bike will be sweet.

cheers.

Ah the lovely nicolai... Some beautiful engineering and a decent result.
Only two tiny details keeping it from my bike rack (besides the $$$) ::):

That bad boy is OMG heavy.
Still has a chain.

When they get lighter by taking the primary torque reduction gearing out (i.e. the cranks turn the primary gears, not a reduction gear or chain) it will be a rational design.

When the chain is replaced with something 21st century-ish, it will be a "revolution."

Until someone, or some company, spends the time and money to figure this out, it's pretty much a purple anodized biopace experiment headed for the "hmmm... that's interesting" corner of the mountain bike museum.

All that said, I'd still love a Rohloff disk hub on my "other" bike.

Hi chaps, I think this may be a little lighter according to a mate who`s in the know.
It may start to appear on XC bikes soon its pretty much a carbon gear box. From what he`s managed to find out about it`s quite light too, but he races and writes about DH. Looks interesting though.
