I've been pretty happy with the xc style chainguides i have been using. The e13 a little more than the mrp. i love the adjustability and construction of the Paul, but havent needed it - yet.
However, recently on BA i've been noticing that the guide is rotating occasionally, i presume as it gets knocked. When the frame was being made i asked sean to add an ISCG mount at the last minute...and i'm glad i did. I fitted an e13 LG1+ today. It took all of 5 minutes. It lined up incredibly easily, and is considerably stiffer in the 'yank it in the bike stand' test.
Initially i am going to run just the top section, though i might well add the taco and roller at a later date...we'll see.
Sea Otter is on, and theres some sweet looking stuff appearing. I see on Bikerumor that they are releasing a 1x10 sort of inbetween-ish guide aimed at rougher/1x10 riding - the LG 1 trail. Cool.
Now all i need to get out into the woods and RIDE.
