New poster looking for help

I've got an Inbred at the moment. It's a 14" and a couple of inches too small to be an effective 'road' bike. I'd like 700cc wheels too but running large vol road tires.

I was over there at Christmas. TBH, a Road-rat with a light build would be perfect... expensive though. and that's why a 'retro' resprayed frame appeals.

I've just been online creating a list of components for a build and quickly realised the problems with brakes / hubs and it also meant more expensive carbon rigid forks for disc mounts. I hate the idea of being under-braked (hence a HOPE M4s & 205mm floating rotors on my xc bike).

Any suggestions for 1" - 26mm clamp stems and 1" steerer forks.
Which powerful road brakes? What about Dura Ace 7700 for £40? Can you use road canti brakes with mtb type brake levers? If so which levers? I want to use flat bars.

For the wheelset I was going to have Ultegra hubs, Mavic Open Sport rims and use a SS kit (spacers for 9 speed to 1 speed and a tensioner that bolts into the hanger). Is that the best way and a resonable wheelset for about £90 + £20 for SS kit?

Are road BBs the same as MTB BBs? If not, where's a good place for a cheap SS chainset and BB? Pref silver.

Thanks for the replies so far.

I don't know much about MTB's but I would assume that the BB's are made for triple chainsets, and therefore wider, probably 113mm as opposed 108mm. Others more knowledgeable will advise, but in road terms you need to decide if you want a single, double or triple. Also different threads, English or Italian.
