I bought one recently. I had a bad cycle crash years ago and have had neck problems since. In order to try to alleviate some of the pain I run with the top of the bars about 2 inches below the saddle height. With many large frames this can be quite difficult. However I discovered that the Specialized Allez has got quite a long head-tube (the Roubaix model is longer still). So I thought I'd give one a go. I bought the basic model, which after a discount cost £450 from my local bike. I stripped all the gear off it and replaced it with a combination of Campag, SRAM and other bits and pieces. The final weight has come out about 8.3 kgs. So far I've got no complaints, the frame seems okay, the only issue I have is the headset which is a very cheap one made just for Specialized, and difficult to replace. I've used steel and titanium frames in the past, and this is my first aluminium one, so it will be interesting to see how it pans out. I think you need to bear in mind the relatively high front end, will this suit you, or do you prefer to get lower on the bike?
