Wheels - Having stripped the hubs down on the existing wheels, and actually cleaned them and regreased them they are considerably better. The Freehub is next on my list of repairs - probably tomorrow. I can't pedal backwards in the cold, something I want to be able to do. Once i have worn the wheels out (the hub is failing), the plan is simply to purchase some Shimano R501 wheels as their replacement. My personal view is that this bike is never going to be a bike for racing on, it is never going to be a top of the range bike, it is a starter/lower end spec bike for someone coming into or returning to road bikes and working out that this is actually what they want to do and there to be used as such, something you can leave at college/shops/work without having to worry about it being knicked all the time (but then I am happy using it in winter, rain and off-road). Some will disagree, others agree, it is each to their own and no point it worry over what others do to their T3 or how hett up they get over it. Once the wheel wear out, I won't claim on the warranty, can't afford to have the bike off the road for upto 3 weeks or so... so I will upgrade as and when then have worn out.
To date, the only parts I have replaced are ones which were either for my safety (new brake blocks, shorter stem, narrower bars, better lights) or have failed (pedals) or have worn out (tyres, chain).
But it is no different to any other school of though such as buying a base model dSLR camera and fitting a professional prime lens to it and I have witnessed people do that...no different to buy a base model car and fitting the most expensive stereo system to it... I could go on, but I think I have lit the touch paper and now I am going to retreat... goodnight
