While building my bike my main concern was in saving weight without hurting performance. There are several parts where I could have saved more weight but it would have hurt performance. Not spending "too much" money was also in my mind:
Brakes: I believe that V-brakes are strong enough for a racing hardtail and most biking anyway. By using fresh cables, ceramic rims and avid brakepads you get monster stopping power paired with great modulation out of a lightweight and proven system.
Shifting: All Shimano! I prefer the shimano triggershifters.
Front derailer: Is an older XTR M-950 which is lighter than newer models.
Rear derailer is Dura-Ace and works flawless in the dirt. I`m doing lots of road riding with my road bike too and like the narrow gaps of the Dura-Ace cassettes gear spacing. You have to shift a bit more but gear selection is better. Front chain rings are working great with a 20t avitar/32t sugino CSP3R/44t XT.
Grips: no soft foam grips. I like the grip of real rubber.
Wheels: Light and stiff wheels by using DT Revos everywhere except the rear drive side where the heavier DT Comps are used. 32 spokes front (radial laced) and rear (3-cross)!
Tires: To me Continental explorers are the best tires! Right now I`m trying some new lightweight rubber (specialized SL) and soon the Schwalbe fast fred (semislick at 355g). I`m running "STAN`S TUBELESS" and got light weight, great grip, puncture resistance, lower rolling resistance, more comfort! To me Stan`s system is a MUST DO!
Fork: SID SL is not the lightest but worlds better in shock absorption than the SID race (had the Race last year and wouldn`t go back-giving up 160g!)
