Question about 1x, cranks, and cogs

Cyclocross and Gravelbiking (Recreational) This has to be the most physically intense sport ever invented. It's high speed bicycle racing on a short off road course or riding the off pavement rides on gravel like : "Unbound Gravel". We also have a dedicated Racing forum for the Cyclocross Hard Core Racers.

Question about 1x, cranks, and cogs

Couple questions.....My current crank set is a Race Face Ride set which has an external BB that fits a 68/73 mm BB shell. It uses 3 2 mm spacers that you can shift side to side to get chain line. Running on my 1x10 set up I am using 1 spacer on the right and 2 on the left. I am thinking of maybe upping the front chain ring next year to a 42 tooth for more road worthiness so I was thinking of getting a set of these cranks https://www.sram.com/sram/road/products/sram-rival-1-crankset
Will these cranks work with my existing BB?

In addition to that I would most likely need a little lower gear than my current 36 offers. I was thinking of also adding this to my rear cassette https://www.wolftoothcomponents.c m/collections/cassette-cogs/products/giant-cog-for-shimano possibly with an optional 16 tooth cog. Has anyone had any experience with this cog? Aluminum on a cog makes me nervous.

Currently running 38x11x36. Not really sure whether the change is necessary. Right now 38x11 is too much for me to maintain cadence on a flat road for extreme distances (I could do the 38x13 combo all day) but I guess I am more thinking tailwinds/downhill etc. As far as needing to go faster on gravel........... the gravel around here is big chunky white rock. Anything over 20-25 mph on this stuff will make my knuckles turn white especially when random loose rocks appear out of nowhere.

Maybe my question should be.."How many of you are running 1x10 with a chain ring larger than 38?"

I have one bike with 42 11-36. The most immediate riding around me has a lot of rolling terrain with some short and steep climbs. The only time I'm in the 42/11 is on paved downhills, and I'm getting well north of 30mph before spinning it out. The lower end gives me just enough to make it up most climbs. I'm also a bit of a masher, so this gearing suits my riding style.

42t single ring is an option for cyclocross racing ,, 12_27t cassette. Low gear being shoulder the bike and RUN.

Now Perhaps get a Road triple, put a disc chainguard in place of the outer (a Bash Guard that is Not thick or heavy )

and a Chain Minder on the inside, to stop the chain from popping off on the inside , on rough race courses.

I have a 48 front, 11-42 in back. I mostly ride it on the road though.

My next gravel/tour bike will have 42 in front, 11-42 in back.

SRAM GXP cranks use a special (24mm/22mm) cup/bearing set. Your Raceface 24mm/24mm cup/bearing set won't be compatible, but you can remove the cups and install the SRAM GXP cups (they all use BSA threading). Note that SRAM road cranks are usually 68mm, so you don't really get any chainline adjustment.

For chainring size, I race CX on a 38/12-28 then switch to a 48/11-32 for road use in the off-season (but most of my road cycling is exceptionally flat).

Something I am not against but yet not really big on is front derailleurs. I just love the simplicity of NOT having them. I do understand the wider range of options more than one ring gives you though.

I am a masher as well. I have a little single speed experience so I prefer to stand and mash vs sitting and spinning. I got friends that prefer to go granny and sit and spin and they have to get out of my way cause they slow me down on climbs lol!

Thanks for the answer to that question. That's good to know. As long as the Sram cranks are engineered to be centered on a 135 dropout spacing then all should be good.

Another option if the rear wheel you are using accepts a XD driver is to get a SRAM 10-42 cassette for a little more top end speed.

I believe that's an 11-speed cassette and I'm running a 10 speed drivetrain. I'd have to look it up but I'm not sure off the top of my head what you mean by an XD driver. My hubs are Shimano XT m8000 so I believe they work for 11 speed on down

A XD driver is a special hub body to accept SRAMs wide range 10-42 cassettes, which is only available in 11 speed so it doesn't do you much good.

The pg 1130 fits on a shimano driver. I think only the sram cassettes with a 10-tooth cog require the xd driver.
The pg 1130 uses an 11-tooth small cog. It's available in an 11-42 wide range.

11-42 cassette - note: Compatible with non XD™ driver body
