So I've got this roadbike, a 1986 Raleigh Marathon, with an outdated gearing system on it. It says Shimano, but that's about it. In a week my train/bus pass will no longer be valid, which is the ultimate chance for me to go commuting by bike. But I want my bike to be in great shape...
I'm thinking about upgrading the gearing system to a Shimano 105 system.
I've been looking around on the web, and came up with the below list of gear.
Shimano - SL-7800 Dura Ace shifters
Shimano - CS-5600 105 10-Speed cassette
Shimano - BL-R600 Drop Bar Levers
Shimano - RD-5600-GS 105 rear derailleur
Shimano - FD-5600 31.8/28.6mm front derailleur
Shimano - FC-5600 105 Hollowtech II Double crankset
1) Can the Dura Ace shifters (for horizontal tube mounting) easily be used to replace the original shifters?
2) Are Dura Ace shifters compatible with the other 105 gear I was thinking of?
3) Do I need to consider other drastic changes while upgrading (is there something that NEEDS to change because of the upgrade)?
I'm not too much of a greasemonkey, so I will have the work done for me instead of doing it myself. But still would like to hear some of your opinions.
