Is it really necessary ?? Can you afford it ??..Drop bar conversions can get tricky and expensive. Drop bars are good for people who have longer commutes and windy conditions.... For short city commutes and errands, flat bars with bar-ends or riser bars are much better. To do a drop bar conversion you will need new brake levers, new brake cables and cable housings, new shifters and new stem. You will need to experiment with different size stems until you get a comfortable fit...I've done it to one of my mountain bikes but mine is a singlespeed so it was very easy and cheap, no need for shifters ..To be honest the only reason why I've done it is because I just wanted my mountain bike to be a little different and not because it was necessary...The hardest part was getting the fit dialed in, I've tried about 5 different stems before everything was just right.
