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)

Help Shogun Selectra to fixed gear

Ok someone please help!, i am trying to make my bike a fixed gear, its a shogun selectra, im not sure what year it is but to me it looks like 80s, its Tapered double butted tubing frame, i removed a sprocket from the cranks and replaced with washers to have a single chain ring. I removed the gear shifters and the derailleur and ajusted the chain length with a tool on the freewheel just for the time being and to see how it would look. Im about to buy some fixed/flipflop gear wheelset to throw onto my bike, THIS IS WHERE i could use a little help haha. because i noticed the front wheel bolt thing or axle was smaller in the front than in the back so would i be able to put this on my bike? ----->http://www.cyclingdealusa.com/Fixie-...-p/zjs100e.htm
My current rims and tires are 26X1.375X1.24 i think
front/back 42/17
i know the one from cyclingdealusa is 16 but im okay with that

Those wheels you linked are 700c, not 26". They won't work regardless of the axle size because they are much larger in diameter than the wheels that frame was built to use.

They'll probably fit tire clearance-wise Most olde MTBs I've had will fit 700x23 no problemo.

Hurdles are rear dropout width, which could be coldset smaller, and brake mounting, which can take a little digging through the olde nutted caliper bins.

EDIT: Just looked at all pics and that ain't no MTB, dunno where MTB idea came from.

EDIT: Oh, 26" wheelset on there. I'm too tired to think. But yeah, frame good to go for 700c clearance-wise.

If you have a buddy with 700 wheels put them on and see if they fit, before buying. No one can tell for sure from a picture.

I've filed out 9mm fork dropouts to fit 10mm axles. Don't touch the top of the dropout AT ALL. I just removed material from the front face of the dropout 'til the wheel popped in there.

Some people say you will die instantly but I've put over a thousand miles on a filed fork.

If you have cool shops in your town you might be able to pick up a fork for $20 or so.

We've got a decent chrome Tange in my shop for $15 ATM.

I'm just guessing about your axles' diameters since you say front axle is thinner than rear (at least that's how I read what you said in first post). Some olde bikes have even smaller than 9mm axles.

I'd guess about 8 minutes filing per side on the Hi-Ten fork I worked on. Mangaloy fork might take a bit more, but not much.

so mangoloy fork is safe to ride on when its filed? is it worth it to buy the wheels and file it down? or are there 9mm/10mm wheelsets for fixed gear around?

would it be worth buying this? http://www.ebay.com/itm/Fixie-Freewh...item3f1cfed2d5
how easy is it to align the chainring/cog for the chain?

is it also possible to, maybe better?, file down the inner/towardhub axle?

Point 1 - don't buy Stars rims, they're rubbish
Point 2- Quando hubs are made of cheese, don't buy them
Point 3 - Low spoke counts are bad news on fixed gear rear wheels because you're applying torque in both directions.
Point 4 - Low spoke counts only work with good quality rims and probably hubs as well.

In other words, these wheels are only good if you plan to sit and look at your bike rather than ride it ... only they're ugly so that wouldn't work either.

Not to be completely negative though, you would get a lot of practice replacing spokes and retruing wheels.

You mean a ghost bike?

I do not even know how to advise someone about setting up a bike - purchasing, building, stealing, whatever - whose foundation is an idea about what they want it to look like.

Dude, you're making a a big deal out of nothing. Just about all track hubs have a 10mm axle in the rear and a 9mm in the front.

What he is saying is that most hubs will have a 10mm axle in the rear and a 9mm in front because that is the norm. Your frame follows that standard. Any 1/2 decent road or track wheel will follow that as well.

I dont see 10mm front axles very often and when I have it was with pretty cheap wheels.
