I think I've got my Ultimate trials build but I'm going to list it anyway and see if there's anything I would/could change.
Koxx Coust V2 Frame (would be nicer with a thicker down tube and a touch more tyre clearance)
Try-all forks (I love these forks so much)
Echo SL Headset
Tarty stem/Trial Tech Ti bolts/TNN top cap with alu bolt (perfect geo for me and this bike)
Try-all Carbon bars
Reset Ti BB/Echo SL crank bolts
Try-all cranks cranks/Trial Tech Ti half ring bash/Echo SL freewheel (might upgrade to ti)
Trial Tech pedals with Ti axles (Tempted by Echo cages with ti axles)
Try-all H hubs built onto Try-all Hole Rims/sapim spokes and alu nipples/Trial Tech Ti hub bolts
Try-all front tyre with Conti super lightweight tube/parcel tape rim tape
Conti Rain King rear tyre with super lightweight tube/parcel tape rim tape
Trial Tech Lite Chain/ 15t Echo ti cog
Try-all/Hope 180mm front disc with ti rotor and caliper bolts and alu lever bolts and nut/Kevlar hose (Could go for a carbon lever blade)
Magura HS33 4 finger lever/SL clamps/Monty hose splitter/alu lever bolt/alu bleed bolts/TNN LGM pads/Trial Tech carbon booster with Ti bolts.
Trial Tech Foam grips.
That's pretty much it I've got no idea how much I've spent on it. If anyone can think of any other upgrades I will consider them.
