Just built my Auger up a couple of weeks ago. I haven't had a lot of ride time on it, but it has all been on the dirt. Mostly on smooth-ish single track. I swapped the stock seatpost (S-Works C-GR), cassette (wider range for the mountains), and tires (just put on some Kenda Small Block 8 tubeless) , so far. I intend to mount up some fenders so that I can use it for commuting as well. Should be an entertaining bike Mine is on the left. The bike on the right is a Specialized Secteur that we cobbled together with parts we had around the shop. My co-worker loves it!
Just out of curiosity, I tried to put a Specialized Trigger Sport 700 x 42c tire on my Auger. Surprisingly enough, it actually fit! It was like riding a light, drop bar 29er. \n\nThe Foundry hs quickly become my favorite bike. It is surprisingly versatile, and quite comfortable. My road and mountain bikes have become almost expendable.
I'm putting my Noah up for sale. The Auger climbs nearly as well, and has just about zero lateral flex, while still soaking up the bumps pretty well. I'm particularly happy that the top tube is a touch shorter than most road bikes, allowing a little more upright position while still on the hoods. I could increase the stem another 1-2 cm without compromising my position on the bike.
