Ok, this is my first conversion of any kind and I need a little bit of help. I picked up an old Fuji and I need to get a new single chainring crankset and freewheel, but I'm not sure what kind. Everything is stock 1970's Fuji. (Sunshine Hub not sure of bottom bracket)

Soooooo, without further ado...

1) Do I need to get a specific kind of crankset to fit my bottom bracket?

2) What kind of freewheel do I need to fit my hub?

3) Any suggestions on inexpensive parts for this conversion? I'm not looking for the cheap stuff, but I really don't need the "nice stuff."

Pictures would help..
Are you sure you need a new chainring and crankset?
Check what you have right now, the cheapest way may to reuse these components (should be easy, Fuji didn't use cottered I don't think)

1) Yes, go to your LBS if you can't figure it out yourself, I just grabbed a 110 square spindle cranketset (Bulletproof) at my used parts bike shop and its working great on my Raleigh Grand Prix, but find out what your spindle length is. The chainring will be specific to the crank. (Figure our your gear ratio before hand!)
2)Any freewheel cog will fit your hub (to the best of my knowledge)
3) Since all you need is a crankset (I'm assuming), Bulletproof (Origin8 now) works great for me, cheap and reliable (bought used). If you do get a new crankset, go for 165 or a similar size, as it will help your pedal strike problem due to a low BB height.

On the topic of cheap parts in a conversion, Velomine has good deals on wheelsets, Nashbar, Benscycle, Newgrounds, and Price Point have most common parts for a decent price.

Only freewheels with more than 15T will work on your hubs, as 15T and lower does not have the same threading as your hub.

Yup, Origin8, Pake, EighthInch make affordable cranksets; you could also use old road cranks.

Yeah, I'm pretty sure I need a new chainring and crankset. The one that came with the Fuji is 52t and is attached to the crankarm if that makes since. I was looking to go with a 46/17 or 48/16 ratio. Thanks for all the help with which brands are good, time to scout around for parts!

I have a 80's fuji del ray that I converted, kept the crank set (sugino RT) swapped the chain ring (stock 52 tooth for origin8 48 tooth) and with a 16 cog on the rear I've been very happy. Find out the size of your chain ring spider thing on your current crank, Id be surprised if it wouldn't fit a replacement chain ring.

Yeah, I checked, but that crankset is just super old and pretty beat so I thought I'd just go the safe route and pick up a new one. Origin 8 sells a lot of really inexpensive stuff... I think I'll end up getting some new pedals too.

Does anyone have an good suggestions on bullhorns? I was looking at these so I could get the bar end brake levers.

If you just want to try them out, flop and chop the road drops, and just reverse the old brake lever, that's what I'm running right now

If you want to replace your crank and chainring that's fine, but unless they're broken you don't have to. You can just thread a freewheel onto your hub. With any luck it'll line up with your small chainring. If not, just rearrange the spacers on your wheel and get the wheel redished. This is the cheapest way to do it. If you want to do it "right" get a new crank.

I was thinking about just chopping the old drops, but I'm going to use them for another bike project I've got going plus the the old brake levers were bent to sh*t. I really bought this bike for the frame and the wheels. I really wanted a fuji for a singlespeed and I couldn't pass it up for $30 haha. I'll try to post up some pictures later.

Sidenote, both wheels were so caked in grime they looked rusted out, but after I got the dirt of they're nearly perfect lol.

Whoa! You have some messy wiring.

Bike looks cool though. Be sure to post pictures when it's done.

That Fuji looks really really nice...makes the perfect conversion. Your headset seem to be missing spacer/s and the locknut...but I could be wrong. I'm very interested in how this will turn out.

Kudos on the History Channel.

Haha, don't judge my wiring! And I have the spacer and locknut, I had them off because I just got done greasing the headset lol.
