A decent bike needs very little major maintenance work. Most LBS in other states refuse to do maintenance work on bikes. To those small shops in small towns, their solutions to many problems are changing faulty or out of adjustment parts. Me, I try to salvage anything that I can. Nothing is thrown away unless they are truly beyond repair. I myself an old cro-moly Marin 7speed MTB. Bought it almost a junk from an "exchange&mart" equivalent just because i like the frame. spent some bucks changing major parts making it whole again. now it runs very sweet on tarmac with 1.50 Panaracer rubbers. in fact it is now my commuting bike which clocks on average 35km/day. when I do go for that ride to Putrajaya I do a total of 70-80 km in one day of use.
