My novice rider(200 miles, total) girlfriend is 5'0" and has tiny hands. Her fingers are too small and slender to operate a modern STI brake/shifter combo effectively, from the drops or hoods. Luckily, her size XS, 2008 Giant OCR3 has those secondary brake levers at the center of her bars. However, she is still afraid to use her Shimano Sora shifters, fearing she will lose control of the bike, as she still not comfortable with the spin cycle rider position(her seatpost is still at the LOWEST SETTING! What should I do? Should I suggest a flat bar and trigger shifter setup....or, should I just wait until she gains more riding confidence?
