I'm looking to get an entry level road bike and would like opinions on a stock allez or a gt rz4000 with the following stuff .its basically a question of getting a newer bike with decent components or an older bike ( the gt is 2000 or 01) with better components
GT ZR4000 ROAD BIKE. 54CM ALUMINIUM FRAME AND FORK. HANDLE BAR: ALUMINIUM MO DO LO AE 2093 ANATOMIC SHAPE. BRAKES/SHIFTERS : SHIMANO 105 DOUBLE TAP 9 SPEEDS/TRIPPLE. REAR DERAILLUER : SHIMANO 105. FRONT DERAILLUER: SHIMANO TIAGRA. CASSETTE : SHIMANO 9 SPEED HYPER GLIDE. RIMS : MAVIC XP 11. TIRES :CONTINENTIAL 4000 GRAND PRIX - HAND MADE IN GERMANY. BIKE IS TUNED AND IN EXCELENT CONDITION. GEARS SHIFT PERFECT. BRAKES ARE PERFECT.
Dont confuse better with a name brand...what I mean is that its possible that sora today is a better group than 105 was 8 years ago...I know this would be true in a tiagra vs 105 comparison spread over that many years.
Also think of where you are in your riding ability and what your riding goals are, and over what time frame.
All of this aside, getting a bike that fits is much more important than what group is on your first bike.
in general I would say yes, I am supporting a new bike. You would (presumably) get a bike shop that wants to keep you as a customer and one that will help you get a good fit. You will also have a warranty, and new components that quite possibly are even better than an 8 year old bike. If you are saying the cost of the two is about the same, then I think going new is your best choice.
