50T Creo Chainring

[Randallmtx]

Has anyone located a 50T chainring with the 110 BCD narrow wide threaded 5 bolt pattern? Looks like Praxis only goes to 46T. I suppose you could use a non-threaded with nuts and bolts but prefer a direct 1:1 drop-in. I’m tired of spinning out!

Take a look around on the web. Searching for bike parts can be fun, and you learn about brands, specs, and what's available. For your case I noticed:

Maybe Garbaruk

110 BCD (5-bolt) Round

Compatible with all 9,10,11-speed chains, 12-speed SRAM MTB (Eagle&T-type), KMC, Shimano HG+, SRAM AXS Flattop chains

www.garbaruk.com

Garb. has a reputation for good quality, but in my experience delivery to US can take months.

Wolf Tooth shows "not in stock" but maybe they will have it eventually.

110 BCD Gravel / CX / Road Chainrings

110 BCD 1x chainring sprocket gravel cyclocross cx road wide narrow wolf tooth drop stop

www.wolftoothcomponents.com

JensonUSA.com lists a bunch of brands with 110 BCD, though only some of those will have narrow/wide.

You'll probably need nuts and bolts, but I think I prefer that in case something gets stripped.

Thanks! Yes I have found quite a few on Amazon. I’ve decided the nut and bolt approach would be fine. Im actually thinking about stepping up to a 52T. I don’t have much experience with gear ratios but worth giving it a shot although it might require a new chain?

52t will really limit your low end gearing. How fast do you need to peddle? a 48t and 11t cassette will get you to a little over 30mph at 80 rpms. are you going faster then that?

 

[Randallmtx]

The online calculator I used shows that 52T and 11 rear yields 30.92 mph at 80 rpm. 48t shows 28.54 mph. So I was just going by that. But in answer to your question I’m spinning out at around 28. Especially on descents.

I ordered a Garbaruk June 22 and received the tracking number on July 20. Tracking shows it received in Sacramento today, so maybe two more days to get to me. So that's a little over a month for me.

you wile sacrificing climbing for going down hill. so if you can put more effort into combing it would be ok.

 

[mschwett]

you could always pick up the used wolf tooth (52t, 110 bcd 5 bolt) one that's on ebay right now for 35 bucks while you search for a new one. you'll need their bolts, which work great. don't forget a drop of loctite per

if you're still spinning out... a driver change will let you go to a 10-42 cassette on the back, also a fairly easy change. 52 in front and 10 in the back gives you about the longest gearing conventionally available!

FYI - Specialized claims compatibility only up to 50T... See https://support.specialized.com/turbocreosl/en/features-compatibility/frames

Is there a reason you're maxing out at 80rpm cadence?

Wolftooth seems to have stuff come into and out of stock; I had to wait a week or two for the 46T chainring to come back in stock. Use their "email me when available" or just keep checking.

I purchased my Garbaruk from R2 Cycling in Germany. I am in UK and postage was only a few days and they do international shipping via Airmail. May worth a look

I'm a spinner and often go as high as 90rpm ... and if I hit 30+mph on a descent I'm probably going to coast.

And yes, a really large chainring would rub against the drive side chainstay. Finding the max. could be tricky.
130 teeth almost touches the pavement.

Sod that for a hill start !!!

I tend to average in the high 80's for cadence. Particularly if I'm pushing rather than lollygagging.

Spinning out on a 46T hasn't been an issue I've faced - from a gravel ride on my Creo E5 with 700x42's...

Each to their own though.

I’m with you on this. My cassette is 10-50T, and there’s no way I’ll ever spin out with my 46T chainring even on a downhill. At some point, I’m tapping the brakes!
