This past weekend I picked up a 2009 Kona Jake the Snake from a guy in Jersey. I want to convert it to riser handlebars which will require a bunch of new parts. The bike is entirely stock. Shimano 105 10-speed (5700 I believe) front and rear derailleurs, 105 STI levers, FSA Gossamer cranks... What I want to do is get the drops and brifters off the bike, put on risers, and put on the CORRECT shifter(s) while keeping as much stock and untouched as possible to keep cost down. I have read a lot of info in the past few days and I think I have a fair idea of compatibility issues between Shimano shifters and derailleurs. I guess I want to show the spec that I'd build to and hopefully get some feedback from you guys on whether it should all work together or not. This bike will spend 99% of it's life commuting in NYC all year, all weather. It will rarely, if ever, see dirt and probably will never be used for any racing. Putting that out there in case anyone brings up dropped chains which I think will be less of an issue commuting than racing offroad. All I would would have to purchase is as follows:

- 31.8 mtb bars and grips
- Shimano SL-R770 rapid fire 10-speed shifter
- Shimano BL-R550 brake levers
- RaceFace Narrow-Wide 42t chainring
- Panaracer T-Serv 700x35c tires

From what I've read I can't really use Shimano mtb components with the 105 group. There aren't many options for flat bar road shifters from Shimano. The R770 stuff seems to be the best bet, the rear derailleur shifter matches up just right I think. However the R770 front derailleur shifter seems like it won't work with the 105 front derailleur. I've wanted a 1x10 bike for a while and I think this compatibility problem will be the right excuse to make this happen for me. I would just remove the front derailleur, put on one of those narrow-wide chainrings (do I need spacers to get the right chainline?) and remove a few links from the chain. Does this all seem functional? I know a lot of serious cyclocross racers will recommend getting a clutched SRAM or Shimano derailleur to prevent drop but like I said, I want to keep cost down and use as much as is already on the bicycle as possible. I think the Narrow-Wide ring will provide enough retention for commuting. Also, please refrain from asking why I want to go to risers or tell me that drops are great and that I should stick with them. I see a lot of that on similar threads and I am absolutely, 100% bent on switching to risers. Any help or insight would be greatly appreciated. If you know a better or more suited shift option please share with me. Again, must reiterate, I want to buy as little as possible. Thank you in advance!!
