I've been using a 30t chainring from Andersen Machine and an inner and outter BBG bashguard to setup a 'bashwich' configuration. Previously, I used an N-Gear jump stop. But, when I bumped it and knocked it out of alignment (which always seemed to be on rooty, technical climbs) my chain would drop.

I purchased the un-ramped version from the Andersen website here:
http://andersenmachine.wordpress.com/product-info/

Image

Both bashguards were purchased from BBG:
http://bbgbashguard.com/Mountainbike.html

Outter bashguard: 104 BCD OVAL (32T 45gr) : $20 + $6 ship
Inner bashguard: 64 BCD (32T 50gr SUPERLIGHT) : $12 + $6 ship

Image

In order to use the 30t chainring, you'll need to do some slight filing on the crank spider.

Image

Image

Image

The finished product!

Image

Image Image

I started out with a 1x8 configuration (in the photo) and eventually moved to a 1x10 setup. I contacted Andersen machine and they assured me the 30T ring was 10spd compatible. I've been running in 10spd for about a year now and have had no issues.

No guide besides the plates?
Are you running a Shimano+ or?

Nice project.

Correct, no guide other than the plates. I was running it with an old LX 8spd long-cage derailleur and had no problems at all. When that derailleur was destroyed in a crash, I upgraded to an XT 10spd medium-cage. I hit some really rooty patches and bounce all over the place (I'm not graceful at all) and I haven't dropped the chain yet. It may also have to do with the fact the bash guards are for 32T rings and I'm running a 30T (even higher guard relative to the ring).

One thing I thought of that could be improved: It would be nice if the offset (where the ring engages the spider) was present on both sides of the ring. When the ring starts to show wear on the teeth, it could be flipped over and you'd get a little more mileage out of it. Or, possibly make the offset part separate from the ring so the ring itself could be flipped over?

That is very nicely executed project Marpilli, well done. Your attention to deail is very commendable. I went the Bling Ring route and I would not go back to spiders. I need a robust skid since my trails are littered with fallen trees and the new clutch derailleurs make the case for bottom chain retention devices moot so my choice is a modified G2 SL chainguide. It modified itself when the part that I no longer need broke off spontaneously. :D

Wolf Tooth Components is now making a 30t XX1 type chainring. Here are some photos I've stolen from the internetz...

When my Andersen wears out I might consider getting one. It's only slightly more expensive than the Andersen SS model (about $10 more). With my BBG bashwich the Andersen has been performing flawlessly. I wouldn't trust the Andersen on a bumpy trail without the guards, though....

There's been talk about those at PinkBike as well.
Somebody there even got one, but I don't recall hearing anything further about it, so it probably works fine.

You might be waiting awhile on that one. ;) He seems pretty busy these days...

You do know the Andersen and the Wolf Tooth are both FC-M770 compatible, right?

The easy solution: Buy a small milling machine and a rotary table.
15 chainrings later, and it's paid off.

Not sure if serious... :|

Both the Andersen and Wolf Tooth run on 104bcd spiders. I have my Andersen mounted on an xt-m761 crankset right now.

Dammit, I'm working on it. :P


On 2nd thought, I should make it a project for axisofoil while he's working for me...

Decided to just do the bbg bash sandwich and go 1x9 for now. Can't justify the extra $250 for the new drivetrain.

Nashbar has an xt RD for $50. IT'S not shadow plus just a shadow version. Plus a chain and cassette is around $70. CRC has an XT shifter for $40ish.

I've got XT Shadow. The bash setup is 100g vs 500g with rings, dérailleur and shifter. I'm going to drop .75 lb.

You want the Shadow+. Believe me. :) The clutch is the best thing ever not just for chain retention but also for easy rear wheel installation (at least the SRAM's Type 2 is).

I like the Wolfhound rings a lot but I am patiently waiting for the S&M stuff to come out soon. ;)

I'll lose three links, have the bashwich and xx1 tooth profile. This chain ain't goin' nowhere. I suspect IF I go 650b, I MIGHT go with the 10 speed shadow+ config.

I'm using a non-clutched XT 10spd mid cage derailleur with my Andersen 30t and an 11-36 cassette. With the BBG setup, I've not dropped a chain since I put it all together. I keep thinking it would be nice to remove the guards (and show off the ring) but I don't want to mess with something that's been bomb-proof so far...

It would probably look better,but, I'm thinking I get the same functionality with less weight.

Hi Marpilli!
(new guy here, first post)

Something sure looks familiar with your bashwich. I've got a very similar setup - using the exact same BBG bashguards, on a GXP Stylo crank with a RaceFace N/W 32t ring. Just to be safe (I HATE dropping my chain) I run a Bionicon C-Guide, with an X9 Type-2 medium cage RD and a 10-speed 11-36 cassette out back.

Cheers!
Chuck from San Diego
