Hi my name is Roland and I've recently got back into cycling after 25-30 years not. Just got a new bike (comfort/hybrid) Opus Mondano at a LBS here in Oakville. My concern is that last Friday I went for a bit of a long ride(20-25 km) and on the return trip my left palm went numb with the numbness spreading into my fingers. the same thing happened the next day on a much shorter ride on a local trail. Anything I can due to prevent this from reoccuring in the future?
