Cannondale F800 Bad Boy conversion

Hi Abs, I moved on from this bike a while back and I’m not sure if I’ve got any photos anywhere. I’m now riding a fixed gear converted BadBoy 8. You can read about this beautiful machine in this post: http://tancredi.co.uk/2007/9/7/bad-boy-8-fixie-conversion

I’ve got a BadBoy Ultra, great for city riding.

Greg, I’m sorry but I have moved on from this frame and don’t have it to hand anymore. If I recall correctly, the Cane Creek headset is only a small amount deeper than the cups that come with the frame. You can probably measure your head tube with the Cannondale headset cups inserted and add about 1cm. Then add the rest for your stem, spacers etc. Sorry I can’t be any more help than this. Its very approximate and if you’re at all worried you may be best getting forks without the steerer cut down.

I think Cane Creek has information about the stack height of their headsets so you could find out the steerer length required from that.

I f I wanted to put a used fork on my Cannondale with the Cane Creek conversion headset, how long a steerer is required? Don’t want to buy one that jhas been cut too short. thnx

Hi Mike, I used a new Shimano LX HollowTech II crankset which has an integrated bottom bracket and fits almost all bikes. It uses external bearing cups that screw into the frame and just has a shaft running through them. Due to using spacers this crankset is a ‘one size fits all’. You should be fine using this with your shell width but check with your LBS before buying.

The only issue you may have is in the chainline, hopefully with the spacers you can get it just right though.

I really like the way these cranks feel too, super stiff and solid, much better than the Truvativs I had on the bike before.

Here is a good page on how to fit them.

What type of bottom bracket did you use? I’ve got a 1995 Cannondale F500 that I’ve customized pretty heavily. I get some noise out of the bb that is similar to the noise that I was getting out of the original bb. Currently there is a Shimano UN53, 68x110mm, Square BB. I’m having a heck of time finding something 110 that looks quality…
