I’ve had two bikes from around this price point over the last four or so years and they’ve not let me down yet. I had a Trek 1.5 to start with then got a new Allez Elite in 2010. The Allez has about 3000 miles on the clock and the Trek did something similar before I sold it.
Bikes at this price are a great starting point for getting in to road biking, if you can stretch to about £600 you’ll get a piece of kit that will last you a long time. I weigh about 90kg and haven’t found the quality to be compromised by my bulk in the slightest.
As mentioned by drinkmoreport above, getting the Tiagra shifters is a nice spec point to look out for and a 9 speed compact group set is ample for any sporting rider.
The good things about bikes at this price point is that the frame they use tends to run through the range up to the £1000 + models with only componentry changed. I worked for a Specialized dealer when I bought my Allez so once the standard Sora/Tiagra kit and standard Alex rimmed wheels started to get worn and needed replacing I managed to get my hands on some OEM 10 speed new style 105 kit and some Mavic wheels so I now basically have a bike with the equivalent spec of the £1100 model for about half that value.
Oh, and I’m also a new dad to a little monster of a one year old boy……time is very much at a premium :D
Good luck
