Business up front-party in the back

Here is a blast from the past. I did this conversion last year...


1X seems to be a viable option these days for most mountain biking.  I like the option of simplifying the setup on the bike and perhaps saving a few grams off the bike so I can gain more beer weight and call it even. Anyhoo - there were two options to go 1X when I decided to do it - replace the front ring with specific BCD or go with a spiderless single ring.  

I have the SRAM s1400 crank...



so I went with the spiderless option MRP Bling Ring (32).  This ring has an offset design to align the chain a bit better...


Installation was straight forward.  Remove crank...




Remove spider with appropriate star wrench...


Slap it all back together.  Reinstall chain minus 2 links and boom - done.  (ignore the temporary homemade chain keeper).




Chain alignment has not been an issue.  Its a little off on the inner most cog but it runs smoothly.  The SRAM X7 derailleur long cage is working OK.




Gearing is 32 up front with 12-36 out back.  Spins out at about 23mph. It is sufficient for all but the steepest climbing where you will suffer like a SS hipster, but for only a short while. Running a Paul's Chain Keeper now.
