I was very into mountain-biking until I got married. Used to ride on the week-ends, with fellow kakis, the Bike-Pro gang. They are based at the Bike-Pro Shop in Taman Megah. Think they still cycle during the week-ends. They do both onroad and offroad.
Misssed the Bt Kiara rides. Before the Oenchala Link came up, I could cycle from Bt Kiara and end up either in Kg Penchala or Segambut Dalam, passing pristine jungle, rivers, single tracks, steep downslopes, very technical rides, etc. Now the damn highway cuts across the area. Oh, once had a durian feast in there too.
If you are interested, I can guide you to Bike-Pro.
Maybe I should dust off and oil my mountain bike and start cycling again.
