Help me Identify this chain ring guard?

[Hugh Smitham]

I believe it is 110 BCD but I don't know who manufactured it? I know Riv used to sell them. Is chain ring guard the correct nomenclature? It was used to convert a triple to a dbl.

Thanks for the help.

Best Regards,

Hugh

Hi Hugh, 

I dont know who manufactures these chain ring guards from RBW's website. However, I do know that the one I have works very well. I believe it is a 40T for my 34T 110bcd chainring. My inner chain ring is 24T on a SILVER 1 crankset. 

What chain rings setup are converting from a triple?

I believe back in the day it was a means to convert a triple Sugino to a double. The bash guard went where the outer 3rd ring went. That was my understanding.  Maybe since Rivendell has the Silver chain rings made, it's not so useful these days.

They are no longer on RBW website.

I just looked at Rivendell's cranks, most are doubles with a guard, the Silver triple doesn't have a guard. And they sell a replacement Silver guard.

So my guard would be for a Sugino triple.

I'm not sure if you're looking for a specific bashguard, or just something that will do the job.  I've been pretty happy with several purchases from BBG - https://bbgbashguard.com/shop/ols/products

Hi Hugh,

I think Rivendell’s stuck with the 110 outer measure for all of time, so your chain/bash guard will almost certainly work on Silver brand cranks the same as it worked on your 110 Sugino cranks. 

My opinion- I think the Sugino guard was/is a little flimsy, especially if you’re thinking of it as a “bash guard”, as you should? I and many others around here like cleaning off the teeth of a larger than second position 110 chainring to get a bit more rigidity and bashfulness out of those guards. And there’s so many lovely patterns of chainrings to choose from. The standard Suginos look somewhat plain, in the loveliest of ways, of course!

Happy Rolling

James,

I appreciate it. I'm putting together a spreadsheet with bicycle parts and accessories for sale. My understanding bike folks like details. So working on that. I purchased it years ago to do a build for a friend,  but he developed vascular dementia.  Pretty sad. I miss the guy.

Oof - that's no fun, Hugh.  I'm sorry to hear about your friend.

Hi Hugh, 

Yes. The bash guard would go on outer 110bcd position. Your largest chain ring would go on the inside 110bcd position. I would tend to believe that there are cyclists that do still use them. If you look at the bash or chain guards on RBW website, the inventory of availability is not very plentiful.

It would be nice if RBW headquarters website sell an assortment of replacement chain rings for their SILVER cranksets, especially ramped and pinned. I have never seen them there before as you have.

With kind regards, 

Kim.

"Yes. The bash guard would go on outer 110bcd position. Your largest chain ring would go on the inside 110bcd position. I would tend to believe that there are cyclists that do still use them. "

Yes, that's my understanding. 

"If you look at the bash or chain guards on RBW website, the inventory of availability is not very plentiful."

When I looked, I didn't dig too deep. All the popular sizes are out of stock.

"It would be nice if RBW headquarters website sell an assortment of replacement chain rings for their SILVER cranksets,"

Don't they? They're just out of stock till their next shipment from Taiwan.

"especially ramped and pinned. I have never seen them there before as you have."

They aren’t ramped and pinned? Is that because Riv favors Friction?

I stand to be corrected. RBW does stock silver chain rings. Most all of them are out of stock. However, all of the silver rings do not have ramps or weird shaped teeth or pins.

"especially ramped and pinned. I have never seen them there before as you have."

They aren’t ramped and pinned?  Is that because Riv favors Friction?

I don't believe this has anything to do with favoritism of friction. I might have something to do with availability ?

I normally buy mine from Spa Cycles in the UK when I'm ordering other stuff from them.

Here in the US one can find a wide selection for many bolt circle diameters and many designs and many colors at BBG Bashguard. The guards seem to run about $21 now; up about 40% I think since I bought my last one 10 or 12 years ago (I've used that same guard in front of 44t and 42t rings on a double-ized Ritchy Logic triple). They even have a superlight category!

https://bbgbashguard.com/

I'll bet that BBG Bashguard is the only place where you can get bashguards for 144 mm bcd rings.

I appreciate the link Nick.

Patrick,

I had no idea. Thank you for the heads up. I still think the Sugino is the more sublime design.

You are welcome. I got this guard from BBG:

My favorite was made by All City - they called it the Cross Wizard I think. I have one on my All Rounder. They came in 36t and 44t, both in black. I was able to de-anodize this 44t one and I like the look much better. I think they are discontinued, but they show up on the 'bay once in a while. 

[Hugh Smitham]

That really looks good.
