I've only been able to find 3... anyone have some suggestions?
These are For XC/Racing use (1x9/10 and SS). Need to be able to mount 28-30t rings.

So far all I can find is this:
White ENO Crank
Middleburn
Surly Mr. Whirly

 

[CrabJoe StretchPants]

I'm assuming 28-30t rings use the granny ring tab mounts then?

 

[golgiaparatus]

Nope. Chainline needs to be 1x9/10 friendly, so the granny tabs are no bueno.

For instance, the ENO uses chainrings with an integrated spider and the Surly uses a 5 bolt 94bcd spider... the middleburn can use both.

 

[CrabJoe StretchPants]

So it has to be the spider style crankset? That sucks.

 

[Polandspring88]

Profiles fit the bill.

not necessarily, just needs something with a bcd of 94.

 

[golgiaparatus]

Pretty much. Either a compact spider or integrated ring/spider. The middleburns seem very good and the weight is good. I'm leaning that way, but I just wondered if there were any other options out there that I was overlooking.

The profiles listed above I think are pretty heavy right?

 

[jonKranked]

for xc race use, yea profiles would be too heavy, even with a ti spindle.

of your options, my vote would be for middleburn.

 

[CrabJoe StretchPants]

And all the 94BCD rings I see in that tooth range require special crankarms or the BMX style spider.

This is something I've been wanting to do as well. These guys: Aluminum Spiderless Chainrings
make single spiderless rings to go with XO, and some shimano offerings- check the link to see what's compatible. I'm pretty excited to try this with a 30t single and a 9x36 rear...

This guy: spam! 30 tooth 104 bcd with shifting ramps - Dirt Rag Forums
also makes a 30t x 104bcd, so just about any crank could work- I'm a bit more sketptical of this one though, and the rings are expensive and don't look half as pretty as the HBC. Good luck!

 

[4xBoy]

I would get the middleburns and a homebrew ring, actually I am probably going to order that set-up real soon.

That guy is in Austin. Quite a few folks around here run that ring, and I haven't heard of any issues.

 

[golgiaparatus]

Thanks guys. Polished X-Type Middleburns on order (come with a 32, which will work fine for all races except the really climby ones). My current BB will work too... bonus.

If you just go faster it will work at them all.

See if you can find some old cannondale codas on ebay. Bad part about it though is octalink BB. I am running a set on my 1x9 with a 29t ring.

good to hear! I'm still trying to decide which setup to go with...

 

[in the trees]

Most newer SRAM/Truvativ cranks (X. series, AKA, S1400) have a removable spider. Then just order a Homebrewed spiderless ring for the SRAM spline pattern. Some of the triple chainring SRAM models have a fixed spider so be careful, but most of the double cranks are removable. I went with a Truvativ AKA 1.1G Singlespeed crank (cheap, about $125 online) and a Homebrewed ring (still on order).

What takes longer... wearing out a Home Brew Ring... or waiting for them to show up. I put it about equal.

I have the non-ramped 30T Anderson Machine ring for 104 mm B.C. cranks. Works great for my 1x9 setup.

Ha! Maybe true, but the HBC rings are very nice and worth the wait. You just need to plan ahead and budget in the necessary time to receive your order.

How to replace a worn chainring with a HBC ring:
Step 1: Buy a ring from another company, install it.
Step 2: Order a HBC Ring from the HBC website.
Step 3: Proceed to ride the new installed ring until worn.
Step 4: Install HBC ring (if it has arrived).

 

[Rockland]

The Andersen is not as sexy looking as HBC's, but I didn't wait forever and a day. Still a solid part.

What cassette are you running? I would be running this with my 11-36 for a 1x10. Do you find that you have enough high-range gearing? Thanks

To be fair, they custom machine, then anodize whatever color you want. You can't have all of these fancy options from a small company and expect not to wait. I can't believe how cheap they are, actually.

Yeah, they are good rings, I actually have 2 on order now.

haha, nice! Still deciding which one I want to get.... Sounds like I should make up my mind sooner than later!

Have 2 red Middleburn spiderless rings... a 32 for most situations and a 28 for things like Eureka Springs FTF where you climb thousands of feet just in the first half hour of the race.
