Hi I have a 21 year scott mountain bike which i have been using over the past couple of years and it is a great workhorse but heavy and hard to get a decent speed. I want to do more road charity events and maybe longer sportives i do 34 mile commutes to work on a regular basis but dont want a racing bike. I am prepared to pay up £700 for a hybrid but dont know what is the best for speed. Also i am a female.
