Not sure exactly how much, sofar the Haan Wheels thing...respoke with thicker spokes, somewhere near $100...front fork revalve at hyperpro without the springs also $100. Both those were payed for by the seller. If i want to get the rest....the set hyperpro sells, front and rear springs plus the oil is roughly $280. And probably another $100 or $150 for revalving the rear and dialing it all in. So give or take $400. @Junglerot, yeah...thought so...I'm about 85kg so i'm going from the expectation that the hyperpro rates will probably be a pretty close match to that since it's a pretty average weight. And I have small kids and no time left to do the work myself.
