I'm just wondering...I have bought a road bike, I don't know the gears as of yet, however I read it has around 24gears. So I was wondering how difficult, an expensive it would be to change it all to a 14-16speed road bike? The whole spec for the bike is:
BTWIN Sport 1

If there were only one bike, it would be this one Features
Power transmission / Propulsion : Aluminium frame for excellent energy transfer.
Efficiency : 27 speeds, controlled from the handlebars, to manage all gradients.
Rigidity : Integrated aluminium head tube for stiffness and precision.
Easy adjustment : Fully adjustable using Allen keys.
Composition : 6061 T6 aluminium frame (8 tubes) with an integrated head tube for superior rigidity (this model). Cr-Mo steel fork. Aluminium handlebars, stem and seatpost. Royal Viper saddle. OUNCE chainset with 50X39X30 triple chainring and crank length suited to the size of the bike. Shimano 2200 series shifters and derailleurs. 3 X 8 gears. 12x25 cassette, KMC chain. Aluminium double pivot brake calipers. Hutchinson tyres and inner tubes, aluminium double wall rims. Standard pedals. Weight: 10.9kg (size 57 with pedals).
