Hola, first time poster here! Hoping you all can help me with some advice... I have not been into biking for about 15 years, back when I was a teenager. Planning on riding RAGBRAI (Registers Annual Great Bike Ride Across Iowa) this year. Long story short, I had no bike and recently received this bike for free. It is a 1987 Peugeot Cannonball Express, according to the info I was able to find online. Seems like it was a great bike in it's day, however it's an ATB (all terrain bike?) This bike is in impeccable condition, but I need advice on making some changes, adding drop handle bars, tires etc... to make it more road friendly for 50mile a day treks! Any advice for a newb on this bike or tips to get it more comfortable for long distance would be great! IDK if matters but the tires are 26x1.625 and looks like it has a Shimano Deore XT light action SIS shifter system.
