Built this up over about 4 months.
Frame- Speedwell sports ( I think)
Wheels- Velocity Deep V’s, machined front.
Most other things are from the previous bike just cleaned them up a bit.
At the moment im running 48 x 16, but most probably gonna change soon, to about 48 x 19. or something that gives me around 70 gear inches. 
I am sure that you will change it to 19T cog
I don’t like it.
Sweet old frame and cranks - but I hate the rest.
Look here for inspiration - Bishops
Are those cranks straight? You don’t want those folding on you if you’re going to be skidding!
Saddle looks like it’s off a kids bike lol.
Needs a brooke saddle and different pedals imo 
49 - 19 will give u 68 GI
u need an 17 or 18t cog
Saddle looks like it’s off a kids bike lol.
Yeah it is haha, i had the original off the bike which looked sick but it broke.
some box rims would make this a HEAP nicer, same with some shallow drops, a brooks, and some different pedals.
Put all these parts on a visp, they’d match it a little better.
