Single Speed Help
Not sure if this is the best place to post, but I'm looking to build a single speed town bike, with this little jobby I picked up for a steal from the Crazy Bike Guy.
Mainly for nicking up to the shops, putting a kids seat on the back, and the occasional commute (will mainly use the road bike for that).
I've currently taken all the gears off it, and set it up to ride on a 40:20 gear (not tested yet, but that is using the existing cassette and front cogs.
I want to drop a lot of weight off it, so the cassette and cog need to go.
So, where do I begin (some photos below)?
Basically, I'm not sure what my options are with the front cranks / cogs.
I think I can take the rear cassette off easily, and then use spacers, but I don't have the right tool.
All advice appreciated.
