I have the latest model 9 FS as a demonstrator, which means that the 07 model I had previously was rather redundant. I use the FS9 regularly, so that I'm in a real position to comment on the usefulness of the bike in day to day riding, so what was my old IXFS to do? Well, I decided to convert it into more of a fast road bike, in preparation for a folding bike race. I swapped in old drop handlebars (up til the late 80's, drop bars had the same clamp diameter that mountain bike bars have now, so if you have old drops, they'll go straight on to your Downtube). I put on Tektro brake levers designed for V brakes (regular caliper brake levers don't pull enough cable), and replaced the twist grip shifter with an old Suntour bar-end shifter I had in a box somewhere. I wrapped the bars with elkhide wrap from www.velo-orange.com (if you don't know Velo Orange, go visit, they rule), and added a honey Brooks B17 to match. Finally, I swapped out the chainring for a 52t item for higher gearing (I'm a bit of a masher), and put on high pressure Schwalbe Marathon tyres. Here's the result, and isn't it a handsome looking Downtube?
