Was thinking of a titanium frame to start with and then go from there, but I don't have too much of an idea where to start in terms of manufacturer.
My road bike weighs already weighs in at 6.45kg, so I'd want to have this thing built a good bit less than that.
Any advice or pointers would be appreciated.
I did one yesterday on a 7.9kg bike which made me think about building up a hill climb fixie.
I've not seen a Ti hill climb bike before mainly because it's easier and cheaper to use carbon or alu which would perform just as well or better, but If you want Ti frame then fair enough.
The main points to sought out are the dropouts and rear hub. I would reckon it would be better to get a light road frame with a chain tensioner than a heavier track frame without.
But if you do go the track frame route I know van nic do a track frame
The winner won on a titanium specialist hill climb bike, which has given me a few ideas. I'm not sold on Ti, but thought that may be a better build for this type of bike - I will also be going for fixed.
Fixed is a great way to do it but occasionally you may need to use your road bike.
Personally I would get an old alu or carbon frame of ebay but that's just me.
When you say fixed do you mean horizontal dropouts?
Yeah, it would be fixed speed, with the horizontal drop-outs, may even opt for a smaller 650c wheel, as I've seen that is popular. I can even remember Laurent Jalabert changing his bike to an uber-light Titanium machine with 650c wheels in the Giro one year, till they outlawed it and put a weight limit on the bikes!!!
Congratulations on the win btw!
I'm going to use the same bike again this year but might look into something with horizontal dropouts in the future. If someone can recommend a cheap, light (1000g) frame with horizontal dropouts i'd be keen
I think i made a forum topic about it but then forgot to update... I'll see if i can get some pictures taken and move it forward.

Only if that's the way it's built.
You can built a Ti bike that's every bit as stiff as alu or carbon, just like you can build carbon or alu bike that's every bit as 'comfortable' as Ti is renowned for being.

You can't build a Ti frame as *light* as a carbon or aluminum bike with the same stiffness. Carbon has the most potential. Stiff and light is ideal for a hill climb.
Then equip the bike with some lightweight tubular wheels, a track crankset of choice and some other parts and you are good to go.
