|From SS Spesh photoshoot|
After selling many Spesh's parts to a friend for building her bike, Spesh was left idle and collecting dust. My initial intention was to sell it off, but after much consideration I decided to make a second attempt to SingleSpeed it. There was another attempt on singlespeed Shogun which ended me with hard fall and a broken helmet. There are 2 most important element of singlespeeding your bike; 1. chain line, 2. chain tension.
First attempt about a year ago.
Cog taken from Deore cassette, sandwiched between 2 larger cogs. Make use old Tourney Rear Derailer as chain tensioner. Note the straight chain line of cog and chainring.
I found this Da Bomb 9 to 1 Pro conversion kit for freehub body (RM65,BicycleWorld, Tmn Melawati) that comes with 18t and 16t cog.
It was 2 strikes of luck when: -
1. pretty straight chain line
2. the chain tension was sufficient on 42t chainring without the need of chain tensioner.
42:16 gear ratio suits me well on flat tarmac. Come the hill, I'll do it standing.
