Just finishing my own dream build over the course of this year and have just added the Hope Tech evo V2 brakes with 183mm rotors, these brakes are fantastic not needing much pressure from 1 finger to slow you down with no fade. I picked them up for £340 for the whole set but I know you can get the non evo set for about £300 all in. Also got some Chris King hubs built with sapim spokes and stans ZTR Crest rims, fairly light weight at 1700g but super strong/stiff and have aided my descending and cornering no end, total cost of build was £740. A friend of mine just got some 2012 Fox Talas 140mm FIT forks with the new kashima coating, tapered steerer and 15mm bolt through for £520 brand new from Israel of Ebay, can’t go wrong with them as cheapest in the UK is £740. Also got Middleburn duo cranks for £200 but a good bet would be the new XT double chainset as you can probably pick them up for £160, worth while thinking of as I went from 3×9 to 2×9 then to 2×10 and the 10 speed if definitely the best as the jump between gears is much smoother and better matched. Also get a Rockshox Reverb seat post from Germany for around £170-£190 delivered, I got mine from HIBIKE and you don’t have to worry about warranty as their is a service centre in the UK for these so all you need is your receipt. Brooks saddles (sweet) and the new easton haven carbon bars and matching stem are great bits of kit. Enjoy your build, it has felt like christmas most weeks/months this year!!
