I'm brand new to MTB and just got a bike. I'd like to get a bash guard and am having a hard time finding one.  I'm not sure if it is because I don't know what I'm looking for or they just aren't that easy to find.

 

The crank is as follows:

 

Truvativ Descendant 6k Eagle, 30T Direct Mount

 

I don't have the option to frame mount so I need the style that goes around the crank, and I can't find any for the 30T.  Am I doing something wrong here or are they just not that common for this configuration?

Here's a link for a Hive / E*Thirteen adapter for frames w/o tabs:

Here's a link for a smoking deal on a combination chainguide / bashgaurd combo:

It looks to me like it will direct mount in between a bb shell and an external bb cup in place of a spacer as it has no holes to mount to an adapter or tabs. Most of them have holes / slots for mounting to tabs / adapter.

 

HOWEVER, really check out what you are buying and check the fitment for your application as there are lots of variation, i.e.,2 different ISCG patterns - old / new, for single chainring, dual chainring, chainring size limitations, and some will work with certain frames and some won't. Keep in mind you can only use an adapter plate if you have an externally mounted bottom bracket - won't work with pressfit - pressfit has to have tabs on frame. Plus you have to take into account how much room you have down there for mounting - some frames get really busy down there with assymetrical rear chainstays, pivot points, shock mounts, q-factor / spindle length, etc.

 

Chain Reaction and Jenson USA both have great, really knowledgeable tech support and no fault returns. I called E*Thirteen / The Hive corporate tech support and the rep I talked to sounded like Spucoli from Fast Times at Ridgemont High - he was so high only dogs could hear him! wasn't very knowledgeable or able to help much with fitment.

 

Of course your best bet is finding a good LBS you like and trust and have them help you figure it out - keeps food on their table and to me there's no substitute for hands on / face to face interaction.

 

I'm still working on getting my setup to work on my Yeti - lots of trial and error!

 

Good Luck!
