I'm trying to build a single speed out of a road frame that I have lying around. As a weight weenie, obviously I'm going to try to build it as light as possible. Here's the catch, I have absolutely no idea about parts from the single speed and fix gear world, and what is compatible or not. So, I would need some recommendations on parts and answers to some questions. Suggestions outside of my questions are more than welcome!
Before we begin, let me briefly list the parts I already have:
2011 Defy Advanced frame set (uses BB86)
Soul S2.0 Wheelset
Planet X KCNC Brakes
Easton EC90 TKO Handlebars
WCS 4-AXIS Stem
What I still need are:
Obviously the first question is, for the parts I still need, what are my lightest options? Concerning the crank, I'm adamant on getting one that uses only one chainring.
Is it necessary to even get an tensioner? If I can get away without one, I'd prefer not to use one so I may keep the weight down.
Concerning the stock rear derailleur hangar, in the case I do not need a tensioner, I would like to get rid of it. Where can I get a plate that will fill in the hole at the drop out?
Headset bearing cover, where can I get one with the least amount of stack height possible because I plan on slamming my stem.
