Frame snapped.

Do I get a badge or something? Is this the cycling equivalent of the piston broke club?

Only if you get extra points for snapping a steelie. Anyone could snap alloy...

Cheap frames.

Could have killed you.

Look for double butted.

In the meantime. Fire some duct tape around it.

A dab of JB Weld will sort that right out

Standards are slipping.
No mention of duct tape.

Edit, oops.

I just replaced it with a Trek Dual Sport 2.

Still thinking of buying a fixie.or hacing a go at making one.

Will dismantle broken bike over the coming week, will have to borrow a tool to remove the doo-dah "bottom bracket?"

cos apparanetly I'm a dinosaur for wondering why there are not cotter pins to be knocked out

Realistically, I'll probably just end up putting all the good bits in the shed, and reusing the wheels and cables, eventually.

There are various types of bottom bracket/crank after cotter pins.

Cheapest/most basic is the square taper (so square hole in the end of the crank). Then there is a slightly more high-tech octolink which has a splined taper (and splined hole).

More modern ones have threadless "hollowtec" bottom brackets. You can see all the way through the middle of these.

Assuming it's a square taper, you'll need a pulling tool to remove the cranks from the bottom bracket then a special splined tool to remove the BB itself.

That said, I don't bother my arse re-using bottom brackets these days unless they are high end ones. They are invariably a ball-ache to remove and do you want to fit a worn one? If it's not coming undone, remember one side is a reverse thread. Also bolt the tool to the bottom bracket using a large repair washer then get a socket and breaker bar on it. I've seen me have to resort to adding 3ft of scaffolding tube on the end to loosen one.

Also, if you're making a single speed/fixie, you invariably need to swap out the BB for one that's a different length to get the chain line correct. I usually keep hold of an old one of a known length, fit that, see how far out it is and order the correct one.

So the build I'm doing now had a 112mm bottom bracket fitted. The chainline (the offset between the front and rear cogs) is 5mm out with the drivetrain componants I'm using (this is a long way out). I just ordered a 103mm bottom bracket for it which should bring it to within 0.5mm.

If you want to find out anything about bicycle mechanics in extreme detail, do a google search for the thing and add the words "Sheldon Brown". He has written articles on everything. There is a lot of stuff about single speed and fixies there too.
