I bought my bike used a year ago and after refurbishing it I've put on about 1500 miles. I keep all components as they came from the seller (almost all are aftermarket including an upgrade to accommodate 700c wheels) and I have been relatively happy with the fit. I have been on a few 40-50 mile rides on this bike without much pain or discomfort.

However I recently realized how short my stem length is (measures about 50-60 mm). I have read many things online that suggest 50-60 mm is simply too short, however the bike fit app I've used has told me my fit is actually pretty good. The frame is 61 cm and I am 6'4. How much of a benefit would I see by buying a 80-100 mm stem to replace this one? If I chose to replace the stem I'd also have to unwrap my handlebars on at least one side.




Thanks in advance
