Do you need to go faster? Just click and you have lower gear. When you have only one shifter to use, this distraction is gone. "What gear am I in? Am I crossing my chain? What's the best gear combination for the next climb?".

With multiple chainrings you have to think about gears. I saved this one for last as this is the biggest benefit.

With less mechanical parts there is a lower risk or something breaking or going wrong. Without you front shifter you get much cleaner and less cluttered handlebars. You can also use short cage rear derailleur (like Shimano ZEE 10-spd rear derailleur) as it has 25t chain capacity, so it can be used with single chainring and 36-11t cassette. Without the big chainring you don't have to worry about hitting rocks and logs with it. It also saved my bottom bracket at a crash at least once. It keeps the chain in place and reduces chain slap. With my extra chainrings gone I could fit my bike with MRP G2 SL chain guide. I also regularly ride 75+ km epics with over 2500 vertical meters (8200 vertical feet) of elevation. Now I can climb 25% gradients without problems. After a while climbing became easier, I was able to make climbs I never thought were possible. I really struggled during the first two or three weeks when climbing and I had to push my bike a lot. With your 22 teeth chainring gone you can't longer rely on it in those steep, technical climbs. There is no denying that, but i will get back to that later. On the other side, your highest gear will be 29% harder to spin. Do you really need that 4.0 (44/11) gear?

but is it? With 2.9 lowest gear ratio (1 full pedals rotation turns the wheel 2.9 times) you can easily pedal your bike at 40kmh (☒5mph). 1x10 setup with 32t chainring and 11-36 cassette offers you gear range of 0.89 - 2.9, which is 63.4% of the original. Let's do some math: 3x9 combo with 22-32-44 chainrings and 32-11 cassette offers you gear ratio of 0.69 - 4.0 (you will get similar numbers with 2x10). This seems to be the biggest issue for most people I talk to about single chainring. All these parts with bowden and cable combined can save up to 450 grams (150g for shifter, 150g for derailleur, 50g for big ring, 30g for small ring and 50g for bowden and cable). You also don't need your front derailleur and shifter anymore. Your big and/or small chain ring, obviously:) I would like to share my experience with you and summarize what it costs you and what can you gain from it. After those 12 months I can honestly say that 9 gears (10 respectively) is all I need. Exactly 1 year ago I bit the bullet and I have converted my Ibis Mojo HD to a single chain ring drivetrain.
