new to cycling and just purchased a 2nd hand specialized allez. Going by the colour (yellow with black carbon forks) i have been told it is an 02 model. I was looking to adjust the handlebar stem for a shorter one and found that the diameter is 1". However going by information on the web about this bike it states it should be 1 1/8". All the replacemement handlebar stems on sale that i have seen are 1 1/8". Has anyone else come across this problem?
