Suntour crank spec?
 

Does a SUNTOUR CW9-XCC 28/38/48T have a 104 BCD (for bash guard fitment) ? Google searching didn't pull up anything concrete, & what I am reading is it could be either a 104 or a 120 bcd.

Without ordering the crankset to find out that information to know what bash guard fits, does anyone here know for certain which BCD it contains? If yes, please post the spec.

Thanks!

You can measure it.

How do I measure a crankset prior to ordering the crankset itself?

Oops. You can't, of course. Sorry I can't help.

I don't think I've seen a 28-38-48T crank that wasn't 110/74.

Are you saying that it is unlikely to see a crank with a 48T to have a 104 BCD?

All I said was I haven't seen one that wasn't.
I'm not going to say they don't exist because I don't know every crank out there.
Don't read more into my statement than what I said.

I did not understand what you were saying. It could just be late in the day & the mind is fogged up, but thanks for trying to clear that up.

Trust me when I say that I don't want to read any more than I need to. I do way too much as it is for non fun things in life!

If I need to get a 104 BCD BG, this one seems common. However, I still am uncertain of the aforementioned crank specs.

I believe the rings on this crank are riveted in place and non-serviceable.

it has the ability to accept a BG. what that bcd is, it is not easily findable.

I'm not surprised that the mounting bolt pattern for the guard isn't known or even mentioned. It's not like replacing guards is a common thing. My experience has been poor in being able to source various guards and having what was available to fit a specific large ring. Andy

Doing a very brief search, I see far more of these cranks pictured with some kind of guard than not. Why not just pick a seller, email them to confirm that they'll sell you one with a guard, and buy it? Trying to figure out these details and buy the parts separately is doing it the hard way!

Asking the forum is where this ended me at for finding that information.

Link to who has that crank containing the BG in place? I'll gladly send out another email.

You have to be clear about the difference between a bashguard and a chainguard.
This link you provided: https://www.ebay.com/itm/SR-Suntour-...n724:rk:2:pf:0
Is not a bashguard. Bashguards are robust and designed to protect your outer chainring on rocky trails when your chainring would have hit a rock as you were going over an obstacle. The bashguard, being larger in diameter than the largest chainring absorbs the impact. The "bashguard" in that link is made of plastic and would shatter if you bottomed out going over a rock. That link shows a chainguard that is helpful in preventing a chain falling off the outside during a shift to the big chainring. These chainguards are not even all that useful in preventing trouser bottoms contacting the chain while pedalling since contact with the chain usually occurs during the pedal upstroke when the pedal is horizontal and your pant leg is well behind the "protection" of the chainguard

OK, Then Forget it
 

Help yourself.. or dont.. I ain't the home shopping channel .

wankers :foo:

Based on the Suntour cranksets I have that probably match this description, it's very likely a 4-bolt 104 BCD spider. The large ring is probably separate from the middle and small ring, which are likely riveted together. The cranksets I have use actual chainring bolts, but the spider has only one set of holes, so you couldn't build it like a traditional 110/74 triple.

Unless I'm using my terms incorrectly, this one has the chainguard: https://www.bikeinn.com/bike/sr-sunt...202/136826955/

And this one has a bashguard: https://www.amazon.com/Suntour-XCC-C.../dp/B00RW53CCY

Found lots of options when I just googled "suntour xcc". I think the CW9 part is just a model year code of some kind.

To pick a bg or cg, the bolt hole spacing would need to be identified of the largest diameter crank gear.
the first link doesn't direct link to a specific cg.

Im thinking along the same lines as you hokie.

That one has a thin plastic chain guard. You can see the little plastic "protuberances" along the circumference where a small plastic screw inserts from the chainring side, in the 10:30, 4:30, 6:30, and 1:30 positions. That's a plastic guard intended to shield the rider's leg from the chain, or catch the chain if over-shifted off the large ring.

It was hard for me to tell from Internet pictures, but you may well be right.

Good luck with your quest, OP! :)

117mm @ 4 holes, crank arms have "ccc896 5sb" & "ccc540 3sb"
very odd spaced holes

117mm is across the center, between two opposite holes? What is the distance between two adjacent holes? Is spacing uniform, or is one pair of holes closer together than another pair (making a rectangle instead of a square)?

Uniform spacing from hole to hole in diameter.
6.25 inch (15.86 cm) adjacent [across] with both adjacent measurements {X**.

Any where to find a 1/2" wide 1/16" thick 8.25" diameter plastic or alloy ring for cheap?
