Hey everyone I recently got a 2016 Blue Norcorss AL CX bike. It is mostly going to live on the trainer but I’d like to set it up as a gravel bike to use when I can. The bike is currently a 2x10 Sram Rival hydro. So I’m looking to upgrade it to an 1x11 or 1x12 Sram.
It currently has QR 135 rear spacing on AClass wheels and hubs. The hub is a HG 3 pawl style. Does anyone know if the hub will accept an XDR driver or as is accept a Sram 11s cassette?
I have purchased a used Rival 12s crank with a PM since it was a good deal. So at the worst case I run that as a 2x10 or 1x10 with the benefit of a PM.
I’m actually converting my cross/gravel bike back to 2x. With 11 speed 1x I just don’t get enough gearing on both ends of the spectrum. It’s fine when it’s pure gravel riding in a flatish area but not optimal when it’s mixed road/gravel or when it’s hilly.
I could put the XD driver on my hub and either buy all 12 speed stuff ($$$$$). Or use a Sunrace 10-42 11 speed cassette to get that 10 toothed cog.
Anyway adding a couple chainrings, a front derailleur and one front shifter will be a lot cheaper than the first option and give me better range than the second option for my type of riding.
Food for thought…
Believe me, I like 1x but I’ve ran all the numbers (gear inches and money) and 2x seems to be the best answer.
That’s a good point and I might just save funds and keep it a 2x10 just with the new Rival crank.
I just really like 1x since I ride/race XC 90% of the time. For now I just would like to know if it’s possible. My hopes are to eventually go to the Sram Rival Explorer 1x12.
If not then I can settle for a 1x11 and still use axs just limit it to 11.
Like I said, I like my 1x setup. I have one of those X-sync 1x chainrings and I’ve never ever had the front derail or have the chain suck.
Still, every time I’m on tarmac with this bike I’m annoyed by not enough big gear for down hills and the large jumps between cogs. We also moved to a hillier area and I need more climbing gear.
Personally, I’d go the cheapest route as I wouldn’t want to put $$$ into an older bike. If you get into gravel more, you’ll probably want real gravel geometry over cross geometry, thru axles and all the modern bells and whistles.
Yes have to back out the OCD in me and wanting to upgrade it everything and just leave it for the trainer only. Cheaper and less stress to keep it as is exempt for the PM crank I got in case I do ride it outside.
I think that is it. Looks like it haha but it also has rh threaded end cap that goes on the 10mm axle. It’s hard to tell if this is for a QR hub or thru axle. Let me see if I can get you a picture of it.
Going 12 speed with a 10 toothed cog opens up a lot of possibilities but it’s the most expensive option since I need all new everything.
Currently, I have a 44x11 as my biggest gear. It’s ok and I could live with it if that were the only issue but I want more climbing gears. If I make the 44 smaller, I lose more and more top end speed.
The max cassette for my long cage rear deraileur is 42.
Going 2X is essentially the most economical by a long shot and provides more range and a tighter cassette.
