Hi Spacebadger, I had a GT ZR2000 a bit like yours, it had a lovely set of wheels built by friend , Tifosi carbon forks, Shimano Flightdeck computer, mudguards with lovingly crafted mudflaps grafted on, in fact every single bit had been upgraded...
...it was so nice in fact, that some thieving b****rd, ratbag, scumsucking git removed it from my garage one night last year, only had household insurance so managed to claim £300.
I feel much better for sharing that!
