Hello, In the past 4 months or so I have been getting into cycling quite a bit. Right now I cycle a cheap mountain bike. http://www.halfords.com/cycling/bikes/mountain-bikes/carrera-vulcan-mens-mountain-bike It was £400 when I got it this summer. I have been contemplating getting a road bike. I am starting to feel really held back by this mountain bike. Id i give it my all complete energy, I can only usually hit around 27km/h and my average pace is only about 23km/h. I am cycling to get in shape and I enjoy it way more compared to when I used to run. Should I get a road bike? or should I wait a few months maybe to see if I still want one? Thanks for any advice.
