Ned, what trails are those? They look similar to the rocks and roots here in GA.
More from Cochran Mill park, near the ATL airport.
What do you mean, that IS the easy line?

My concern would be the axle rubbing/fretting the frame. Is there a washer between the end of the axle and the frame, or something else to be sure that it doesn't rub?

Thanks for the pics! I'm a bit surprised to see that there is not a metal insert for the left side of the axle. Is that common on thru axle designs? (My Chiner is old school QRs )

also, is that $456 for the Workswell frame in Australian, and does it include shipping?

D36, I'd seriously consider building a carbon wheelset. If you can build the bike, you can probably build a wheelset. The only tool you absolutely have to have is a spoke wrench (which you should have anyway). You can use the frame to check dishing and truing if need be, and plucking the spokes gives a good idea of tension and how even the tension is. The downside is that it will take longer to get it up and riding. The big upside is the being able to say "I built these wheels". Women (or men, or whatever) will throw themselves at your feet.
But seriously, you can get pretty close to US$500 for a carbon wheelset. That's probably closer to AU$700, but I think it would be worth it. Everyone says wheels are the best upgrade, so why not upgrade from the start? My 27.5, 35 mm inside width rims were $380 US including shipping and paypal fees. I used XT M8000 hubs at about US$70 total. They weigh 60 grams more than a set of DT Swiss 350 hubs, and will require a little more maintenance, but I decided to go with the XTs (I used DT 350's on the first wheelset I built). I used DT Revo spokes, but DT Comp (or similar) cost less, so you could have hubs and spokes for around AU$150. Depending on the rims you choose, you might even get closer to your original $ target.

Would you still need an eccentric bottom bracket or some other way to tension it?

The "off-road riding" bit probably got cut-and-pasted from a listing for road wheels, along with the 140 psi number.

Nice! Can you post close up pics of the rear dropouts and the rear brake mount?
Also, is the rear derailer hole sized to run a full length housing, or do you just put a piece on the jump from the down tube to the chainstay?

Nice! I see you have changed to more aggressive tires. Pretty soon you'll be seeking out drops and rock gardens Ok, maybe not, but mine has been great for my confidence and ability. I don't ride anything extreme, but it is very satisfying to ride something that many people would have difficulty walking.
Too bad about the web saddle, but if the new one feels good and is durable I'd call that an upgrade.

Some pics from my ride today- Cochran Mill Park in Chattahooche Hills GA. This is my favorite 'local' trail- it's second closest to my house, about a 30 minute drive. It's also only 18 miles from the Atlanta airport. This area has (or had, at least until recently) very little development despite being so close to the airport, and is a bit of a mecca for road riders. The park has been here for years and had several trails and roads, but in the last few years they allowed a local group to build new trails which are much better for biking.
If you're a fan of The Walking Dead, part of the episode "Chupacabra" was filmed in the park- the scene where Daryl's horse gets spooked by a snake, and he falls down the hill into a creek and stabs himself with a crossbow bolt. That's on one of the older trails (just a road, really) which isn't much fun on the bike.
This is on the Yellow trail. Lots of granite and roots and some decent climbs, but nothing super steep or long. Mostly lots of up and down, sweeping turns, and a lot of fun. There are big rocks/small boulders sticking up from the soil everywhere, and the trail runs next to and over several. Most of them can be used for ramps if you're up to it. There are some larger rock formations, especially on one of the hills, but I didn't get any good pics.
The park area used to have four or five old mills. None of the buildings remain, but there are two dams and several waterfalls. There's not usually a ford or crossing here, but the creek is down a bit and it would be easy to jump across in one spot.
This is another one of the falls, on a branch of the creek a few miles upstream. The pic is from back in the spring- a bit more water then.

One more from today. I guess I should put these in the Recent Ride thread...
This one is a great rock. The other side is an easy slope with no step, so anyone can ride up it. You can turn and roll off the side, or wheelie off if you're up to it. The smaller rock in front doesn't connect, so you can't really roll down this side.

Thanks! My wife is a photographer, I'll have to ask how many compliments she got on her pictures today
Like most photos, it still doesn't capture the whole scene. It doesn't really show the contour of the rock- in the foreground it is an easy roll up, but the other side (behind the bike) is a really good step. Mother Nature makes the best alt lines.

Past due for an update on this one- I was pretty bummed that the 2.8 tires wouldn't fit the rear on my -057, and decided to try and find the biggest tires that would fit. On the MTBR plus bike forum there is a thread on 27.5+ tires that has a spreadsheet of estimated tire widths on different rim sizes by Craigsj (http://forums.mtbr.com/26-27-5-29-plus-bikes/27-5-tires-931412-post12516812.html#post12516812) that gives an idea of how different tires will compare based on the bead-to-bead measurement, or how wide the tire casing is. My measurements for the b2b width and mounted tire width are all wider than his measurements/calculated values, but it does give a good idea for ranking the tires.
His formula predicts that the 2.8 Trailblazer should be 64 mm wide on a 34 mm internal rim, whereas I measure closer to 68 mm wide on mine. Pretty close, but since the chainstays on the -057 are 70 mm it makes the difference between "enough clearance" and "rubbing through the paint". The next smaller tires by b2b measurement are the 2.4" Geax Goma, WTB Trail Boss, and Continental Trail King. I decided to go with the Trail King, and so far it works well. I got a wider b2b measurement, but the actual width of the mounted tire came in just under 64 mm, just 2 mm above his calculated width. This gives me just over 3 mm (1/8") clearance on each side. I'll still need to keep an eye on it (and not ride in thick mud, but I wouldn't do that on trails here anyway), but this is probably the fattest tire that will fit. My 29" rims are 25 mm internal, and Continental X-King 2.4's on them measure 58 mm wide (3 mm wider than Craigsj's prediction).
The bottom bracket clearance is about 1/2" less with the 27.5 wheels than with the 29" wheels- dropped from about 10.75" (27.3 cm) to 10.25" (26 cm). I do get more pedal strikes, but that will probably change as I get used to the lower clearance. The feel is almost the same as with the 2.8 tire on the rear- it certainly is smoother than my 29" wheels, due to the lower pressure. My 29" rims are 25 mm internal, and Continental X-King 2.4's on them measure 58 mm wide.
Tough to see, but there is clearance
No problem going up this if you pedal at the right time
Summary of my numbers-
29" wheels-
25 mm internal, X-king 2.4- 58 mm wide
27.5" wheels-
34 mm internal, Nobby Nic 2.8- 69 mm wide
34 mm internal, Trailblazer 2.8- 68 mm wide
34 mm internal, TrailKing 2.4- 64 mm wide
