Hi,

since I have sold my specialized hardrock I have been looking for another bike,

and then I got the idea of building one (within budget)

I am looking into these two frames,

a) https://vancouver.en.craigslist.ca/bik/582420600.html

b) https://vancouver.en.craigslist.ca/bik/603249033.html

for these frames how much more do I have to spend to get me on the road?

and please comment on the frames too.



p.s. I would love to keep the whole thing under $500cad

Unless you're incredibly lucky with eBay or have friends who're dumping equipment left and right, this is not likely to happen. Even if that's the budget after buying the frame, it's going to be hard.

A wheelset to match one of those frames would likely be ~$200 at the absolute bottom-of-the-barrel. You might be able to build a much better pair for a bit more.
Assuming you grabbed the one with the shocks, you're good there, but the other frame would need a shock (so it would seem, at least). Don't know how much that would be. Both would need forks - probably 6" forks at the bare minimum just looking at the frames. There's another $150.
After you grab wheels, you'll want some tires, figure $60 for the pair, minimum, plus tubes.
Then you still need a seatpost, a seat, a headset, handlebars, brake levers, shifters, grips, cabling, a crankset, pedals, a chain, a rear derailleur for both (a front derailleur for the second frame), and a casette.

I've completed three frame up MTB builds. There's only one way keep within a budget. Buy a donor bike and transfer the parts to your new frame. Make sure the shock will transfer OK. If you want to do it piece by piece, it can be done. But to predict what it will cost you is impossible without knowing which components you want, i.e., Acera or XTR, Manitou Axle or Fox F-100. Make a list of the parts, check final bids on ebay (plus shipping) allow $100 for errors, cables, etc.
