I dont think I will do proper off roading but to be honest I dont know, I am 32 and have not owned a bike for 15 years.
What are your thoughts?
I am 32 and had not rode a bike in around 18 years until I got my boardman mx race hybrid (looks like a mtb , has 700c roadbike wheels with tyres similar to a CX bike. (about half the width of some mtb tyres the slimmer the tyres the faster you will go because of less rolling resistance)
I bought it because I thought going straight to a road bike would be to big a jump and with the riding position being less relaxed it would cause more aches and pains before i would adjust to the bike.
It's something I regret very much and I will be buying a proper road bike next year during the sales most likely.
Something about MTB style bikes just made them seem safer for someone who had not been on a bike in years and yes I was very unfit when I started (close to 17stone at one point and 14stone now although im 6"3.5 so not overly fat)
10miles was a hard ride and my hamstring would start to ache fairly badly.
A few weeks later I was able to go 20miles before my hamstring would start to ache, a few weeks later I was able to do 30miles in one go.
I'd imagine I'd have had more pain with the road bike during the adjustment period but I still reckon I would have been better of going straight to a road bike..
some of the cycle paths I ride are far from perfect but I see road bikes on them all the time going around the same speed as me if not faster.
one thing you will learn to hate very much about upright riding positions if when it's windy you will feel like you are going half as fast for twice the effort.
Unless you are sure you need a MTB then IMO it would be a mistake to get a mtb/hybrid just because you think the riding position will make the transition easier.
I'm not the only one on these forums who asked for advice and then ignored it and got a hybrid anyway and so far non of the people I have witnessed do the same has claimed to have been happy with their decision still a few months later they always regret it.
also front suspension is a waste of time I'm fortunate that with mine there's a switch to lock the suspension so I ride like that 90% of the time all the front suspension does is sap your energy.
if decathlon have a store near you
http://www.decathlon.co.uk/triban-3-red-road-bike-id_8274036.html (click "my store" at the top right) with the red triban 3 in stock then that would be a very good starter road bike for only £300 (the white version has worst specs for the same price)
