I spent £850 on the gear set up with shop discount, im not sure id bother with the brakes stick with the avids, and when it comes to replace the cassette ill probably opt for a slightly heavier ( by about 25g) sram for half the price.
That said i have been impressed with the set up, esp the chainset which is very stiff and light.
I think you have to look at xtr as a very long term investment, i dont think ill replace it for years to come now it’ll pay for itself in reliability and im not sure it’ll go out of date soon.
worth saving up for, but not sure now is the best time to buy – id wait until they change the model year you may get a clearance deal if your lucky
