Hi guys
If my English it's not good sorry, I'm from another country Romania.
I want to buy a retro mtb for me to use it to commute (30-45 min) to work, mainly on paved roads, some dirt roads . And maybe have some fun on weekends.
They are worth the money?
1. specialized stumpjumper - frame - ridden by a guy 1.80m tall - 245$
2. trek 3500 alpha - frame 22.5' - 211$
3. gt timberline - frame I will find out later - 184$
specialized condition 8.5/10; gt and trek 7.5/10
I have 1.83m/6ft height and 110kg/242lbs
If none of them are good for me maybe you can recommend me some new bikes. My budget is 320$.
