Hi There Hubbers I am looking at upgrading my Schwinn Rocket Pro(its 16 inch frame)to be more of an aggresive trail bike for SA - all ideas and thoughts would be much appreciated. It has 5 inches of rear wheel travel on the back and 120mm on the front - i was thinking of getting the new Rock Shox Sektor(110-150 mm) with 20mm Maxle - do you guys think it would be a bad/good idea? I have Truvativ Hussevelt bars and a 70mmm stem, Maxxis Minion 2.35 front and rear, Alex DM 18 rims, 180 mm rotors front/rear. Also im not sure what drive train setup to use (single speed with chain device or a double chain ring with chain device )I would prefer to use a single chain device because the chain does tend to jump off on rough terrain........any ideas on rear cassette/front ring setup? I ride mostly single track and trail but i have to get to the top of the hill first.........
