Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

Fixed dual suspension

I ahve a buddy that has a inexpensive "Next" bicycle that needs some repair. He has since bought another bike and this ine is just sitting around. Anyways........Its dual suspension and could be had for cheap I believe, would it make sence to convert it or dare I say a waist of time? I havent seen a fixed/ss dual suspension, If theres any out there can I see some pics?? I suppose I could replace the rear shock with a ajustable rod with heim joints on either end.

Opnions/thoughts/pics??????

Wouldn't chain tension be heavily affected (negatively) by the pivoting of the rear triangle?

I think those dept store type FS MTB's have a unified rear triangle. If so it would work. I keep bumping into those old URT MTB's from the 90's online and consider making a conversion but I never will.

a unified rear triangle still wouldn't work, as the fulcrum point is behind the bottom bracket. for a full suspension fixed to work (with out a tensioner, which would be a bad idea in itself) the fulcrum point would have to be at the dead center of the bottom bracket.

Such is the case with all Next bicycles. I wouldn't even garbage-pick that bike, but I would certainly be interested in seeing someone make a full suspension into a fixed-gear. This is the way to do it for cheap.
Is your buddy trying to sell the bike to you?

Actually the fulcrum is ABOVE the BB and the entire rear triangle pivots on that. Check This Out

No just a 10 year old frame gathering dust on thier shelves. Schwinn actually made them first with the introduction of the homegrown but the fad gave way to longer travel machines.

I say make it singlespeed? Seems a lot more practical than a dualie fix. If chain tension/suck was an issue, there's always a springy tensioner.

ahh, I was thinking of a different set up, my bad... I dunno still seems like a real bad idea. trying to skid would probably put alot of feedback on the cranks, leaving you hopping all over the place. single speed would be safest. but remembering which board I'm on, I say go for it!

I was thinking of replacing the shock with 2 heim joints (ball joints) with a fixed rod between them. That way it would act like a hard tail. Throw some cheap ass slicks on it and ride it for what its worth??

hiem joint:




Im also trying to get a $$ pot up for either a Langster or Pitsa. Maybe the money is beter spent elsewhere than a K mart bike?

Heres what you do to get rid of all problems. Take out the Rear Shock if you call it that. Than get a seat post that is approx the size of the shock. Drill holes thorugh both sides of the post. Put in position and tighten the bolts that held the shock.

Smoking crack is cheaper and safer than converting a FS Next into a fixie. Makes more sense too

sounds like you've gone through at least an 8 ball to think making a dui special walmart full "suspension" bike into a fixie is a good idea. must've been one of those 4 am too many lines idea huh? you can polish a turd, but you can't polish diarrhea.

Well.......gotta give me a *little* credit Im jonesing for a SS/Fixie. Maybe not one of my brightest ideas to date, but it dosent hurt to ask opnions (constructive criticism is appericaed) before dumping any money into a pit. Thanks for the advice, Im gonna pass and keep my eye out for a older (good) frame or buy something new.

You can polish a turd, and polish a turd......in the end, its still a turd!
