I want to convert an older Nishiki mixte bike from drop bars to upright bars. I am going to keep the stem mounted shifters but need some advice on brake levers. I have read some of the info on long vs short throw levers and which calipers for each but still don't understand it all. Could someone recommend a low to mid -level brake lever that will work with the center pull brakes shown in the pic? I am asking for a brand and model number that I could buy from Amazon or ebay that someone has actually used successfully on this type of caliper. Thanks!
