Want a clutter free cockpit? Still getting confused shifting from granny, middle and big cranks? Not using all of your crank ratio's specially the big one? Single crank setup or 1x viable option Read on.
1x setup been around for a couple of years for good reason. Riders want less of everything clutter on their cockpits, weight of 2x; 3x crank setup, and FD. One by setup alternative while maintaining what you already have albeit less.
With the introduction of Clutch derailleurs and Narrow wide replacement chain rings 1x setup now gets added protection from dropped chain.
Now will break down the different methods of converting your existing drive train components to One by.
Simple 1x setup
Remove two UN-used chain-ring from the crank, leave desired crank.
Optional add a bash guard for added chain retention.
Use the FD as pseudo chain guide while removing the crank shifter and cables.
Adjust chain line to suit.
Tune your drive train.
Proper 1x setup
Remove two UN-used chain ring from the crank.
Remove FD and FD shifter.
Add a chain guide either on the ISCG tabs, BB, or Seat tube.
Adjust chain-line.
Tune drive train.
NEW 1x setup
Remove all the stock chain-ring on crank, replace with NARROW WIDE chain ring.
Remove FD and FD shifter.
Adjust chain-line.
Tune drive train.
Optional Add a chain guide ISCG, BB, or Seat tube type.
*most bikes have no ISCG tabs. So consider the BB or Seat tube mounted chain guides.
*if you already have the newer clutched type RD then good it will help with chain retention.
Simple right? Consider the following.
Do you have the proper cassette ratio? I believe that 11x34 minimum cassette ratio to run 1x setup with at least a 32t chain ring up front but if you are fit then...go lower on the cassette ratio.
Are you prepared to suffer? The granny gone (22 to 24t), big ring gone (42-44) you are going to loose your walking pace-uphill-gear, and your ROADIE ratio prepare for the compromise.
Does your bike have a ISCG tab? If not the BB, frame attachment chain guides cost more than the standard ISCG guides.
Narrow wide chain ring a fairly new innovation spawned from SRAM high-end XX1 drive train. Ramped crank teeth to prevent the chain from getting knocked of the crank on off-road rumps. Combined with Clutch type RD and you got poor man XX1 less the specialty Eleven speed cassette.
