Search about on the net, you will get a lot of items a lot cheaper, Merlin are a good site which never seem to come up on google, also look at on one web site, they seem to sell items at really stupid prices like £250 brakes per end for £100 or less, schwalbe tyres at £20 instead of £45. I searched high and low to find things to sell to fund my dream ASR-5 build, thought I had nothing to sell but scrapped together another grand some how! where theirs a will theirs a way! Its really nice having a custom specced bike just the way you would want it, and then to piece it together yourself is all part of the journey/fun. I got my Yeti frame from free flow bikes, free delivery and price matched frame at £1350 also chris king headset at £130, very good service and will price match anything, how a bike shop should be run. You could always get a Canyon like suggested earlier then sell the frame and stick the parts on the frame of your choice ie Yeti ASR-5 as this would probably work out to be the cheapest way as their prices can’t be matched and the parts are top notch.
