XO-2 in the woods


IMG_5254, originally uploaded by rackntroll.

this was an eye opening experience for me for 2 reasons:

A) i have not ridden a 26" wheel off road for a few years. the last 26er i was riding off road was one of my 2 schwinn homegrown frames (fantastic frames built by yeti in the mid 90s)

B) i have not ridden a geared mt bike offroad in over 10 years!!! i have been a devout single speed MTBr for some time now.

having a couple gears in the dirt is kinda nice, EXCEPT for the constant and irritating sound of the chain slapping the stays. a buttery smooth and silent singlespeed drivetrain is a very beautiful thing.
while riding this bike off road, i really only used 3 of the 21 gear combinations. the 40T middle ring paired with the 28, 24, and 21 tooth cogs (the 3 biggest). having the large chainring was a welcome change from spinning my singlespeed 34:19 to the trails.

i dont know if its me, the geometry of the bike, having low end gears, or all of the above, but i was having a hard time keeping the front wheel on the dirt while climbing. this bike really wants to pull a wheely! a couple more rides on it and im sure that wont really be an issue.

i have been riding 29 inch wheels in the dirt for a couple years now, and shortly after entering the trail head with my 26" wheels i remembered what makes the 29 so great- being able to run a low pressure with out bottoming out against the rim, not getting hung up between roots/rocks as frequently, and yes, the larger wheel really does smooth out the trail significantly.

now it may seem like i am bashing 26" wheels, but im not. it was an awesome ride, and this bike handles very well in the dirt, i just need a couple more rides to "dial it in."

practice: part duex


IMG_5223, originally uploaded by rackntroll.

i intended for this to be a usable canti boss, and it is usable, but it didnt come out exactly as i wanted so ill call it more practice....into the scrap bin!
i made some very accurate cuts, right down the the thousandth, really getting to know my machine. it was also good practice figuring out the the best order of operations to make more of these.

practicing for the next small machining project, it went well. stay tuned for the end result!

cantilever brake boss widget

i made this small fixture for what reason?
a. to clamp into a vise to miter the bosses
b. to hold the bosses for brazing
c. all of the above

Frame No. 2 - 12

finally getting back to finishing my second frame!
in order to build this fork i needed to figure out and make a few things.
a hole saw arbor, a drawbolt, and some way to miter the unicrown fork blades, and to hold the fork for tacking. i did all of those and the fork finally came together, and quite smoothly i might add!
i still have to put the canti bosses on (and make a new gadget to do it with).
