word of caution about bikesdirect though, some models are hit or miss. there are numerous instances where people's frame have been sub-par quality. theframes BD gets are made by reputable manufacturers that make frames for other big names but the issue with BD supposedly has been the quality control. there isa reason they can afford to sell at the prices that they do, which really is too bad because its a great deal. getting fitted for a bike is the most importantthing, its like a pair of running shoes for long distance runners. if the equipment doesn't suit you, you will not like the activity. having said thatabout BD, there are cases where people have gotten a very well built frame and are very happy. then there are also people whos frames have a shotty weld job,they say the frame had a very dead feeling. so it seems like you have to take your chances and hope the one you bought is from the good batch.
do you live somewhere where it gets too cold to be biking in the winter? if yes you can get amazing deals on 09 models from local bike shops. local shops dohave a premium on their products but when it comes to a bike they also provide a service thats justifiable. if you can get an 09 model for 25-30% off theregular retail + free bike fitting and then they throw in a few small goodies like bottle cage, pedals etc then you've got an awesome deal. testing out abike will give you a better idea than words ever could. there are a lotta good entry level bikes. I've personally test rode the Cannondale CAAD9-6,CAAD9-5, Fuji Roubaix n Roubaix Pro, Trek 1.2, Giant Defy 3, couple Devinci's and Specialized Allez. they're all entry level bikes and I ended upbuying the fuji roubaix because it was an 08 model when i got it in the spring of 09 and it was a very comfortable fit for me. the cannondale would've beenmy first choice but it was an 09 model and so 30% pricier than the fuji. the CAADs are very solid bikes, fantastic performance to price ratio. the giant defy3and specialized allez are also very good bang for your buck. the allez has a slightly more of a racing geometry, same with the CAAD to an extent. the giant isa bit more of a relaxed ride imo. try and get an entry level frame with at least the shimano 105 or SRAM rival rear derailleur. the front derailleur isn'tas big of an issue. same with shifters, the difference between 105 and the lower tiagara is pretty significant. 105 and Rival are good groupsets for starters.you can always upgrade to ultegra/force or a campy in the future as you ride more.
