1 x 9 speed setup

The key advantage is you can do away with having a front shifter, front derailleur and associated cabling. You also do away with a front chainring as well. You do however need a few extras - without a front derailleur the chain can easily jump off the front chain ring.

Here's a picture of a prototype that I made. It works well. You'll have to excuse the dirty great bolt holding the clamp on, its was just temporary to make sure the concept worked. The picture also shows a 24t granny ring, but the chain keeper profile it optimised for a 28t chain ring. A bash ring is also a good idea. The best answers are voted up and rise to the top.

Voting to close as its too broad. Without knowing budget, rider strength and terrain being ridden, no recommendation can be made. IMHO the best 1x9 setup on the market today Microshift Advent is still too much of a compromise for off road use.

We can't tell you what gear ratios to use because we don't know how strong you are, or where or how far you'll be riding. Can you re-word your question to something like 'how do I figure out what chainring and cassette sizes i need if I convert to 1x9? It will be cheaper than getting an x7 crankset it will be single ring specific and it's a much better crank over all.

And you can get replacement chainrings fairly cheap. I understand that you already have the 32T ring but unless you are only going to be climbing it's too small of a chaing ring for the front. I run a 36T on my down hill bike with an on the back and I can climb hills just fine.

If you do want to keep your 32T ring you have to make sure the BCD is the same as the x7 crank. The BCD Measures the spacing for the 4 bolts that mount the ring to the crank. Im pretty sure your shimano ring only has a 64 BCD though so I doubt it will fit on the proper ring. Gear range on a SRAM X11 or X01 11 speed drivetrain is about as good as it gets for a single chainring drivetrain setup.

Notable components in the here are actually the SRAM cranksets. While X-Sync chainrings are available between T, SRAM cranksets are perfect for using a spiderless chainring to save even more weight and scrilla.

This is something I will touch on later. Of course, all of this comes at a cost. While SRAM was the only player in the 11 speed market for a while, Shimano joined the party this year.

While the major differences are debatable, I see one of the most important to be the cassette size. Rather than require an XD driver, Shimano have stuck with a T cassette.

This may mean those happily using an XX1 or X01 drivetrain may find climbs slightly harder or spin out on the descents. Another notable difference of the XTR M groupset is the cranksets. While the SRAM cranks are able to be used with a 28T chainring with the appropriate spider or spiderless , Shimano only offers a 30T chainring as the smallest option, despite a custom proprietary BCD. While most Enduro racers would never consider running a chainring this small, those wanting to travel longer distances, or the ever growing female and youth markets may be concerned about the gear ratios for those gruelling climbs.
