Methotrexate 2.5mg Pills $138.00

November 12th, 2012

Methotrexate 2.5mg pills $138.00 I have the pleasure to introduce to you one of my favorite builds in recent memory, methotrexate 2.5mg pills $138.00 a road bike for Patricia:

Methotrexate 2.5mg pills $138.00 Let us first note that some Conti Classic tires are destined for those white Velocity rims, methotrexate 2.5mg pills $138.00 fear not! This is just what was on hand.

Methotrexate 2.5mg pills $138.00 So the most refreshing thing about this is all the lovely silver, methotrexate 2.5mg pills $138.00 am I right? This is Campy Veloce 10, methotrexate 2.5mg pills $138.00 great for anyone who thinks that 10 is the proper maximum number of cogs on a cassette, methotrexate 2.5mg pills $138.00 and just easy on the eyes as well as working flawlessly. Methotrexate 2.5mg pills $138.00 The rims are Velocity Aeroheads in white, methotrexate 2.5mg pills $138.00 and a Thomson seatpost and stem and Ritchey Classic bars round it out. Methotrexate 2.5mg pills $138.00

Methotrexate 2.5mg pills $138.00 Before I talk about the challenges of this geometry, methotrexate 2.5mg pills $138.00 some more pics of the frame:

Methotrexate 2.5mg pills $138.00 Ok, methotrexate 2.5mg pills $138.00 so Patricia came to us with a Davidson custom frame that fit well, methotrexate 2.5mg pills $138.00 but she wanted some tweaking and more to the point, methotrexate 2.5mg pills $138.00 she wanted lugs. Methotrexate 2.5mg pills $138.00 Conventional lugs are cast with a conventional geometry in mind – 73 degree seat and head tubes, methotrexate 2.5mg pills $138.00 60 degrees between the DT/ST & DT/HT. Methotrexate 2.5mg pills $138.00 Well. Methotrexate 2.5mg pills $138.00 Not so much here. Methotrexate 2.5mg pills $138.00 We were shooting for a traditional look, methotrexate 2.5mg pills $138.00 so didn’t want to go past a 2 degree slop on the top tube; and we wanted to do a slack head tube and plenty of rake in fork for toe clearance. Methotrexate 2.5mg pills $138.00 All of that helps to use off the shelf lugs, methotrexate 2.5mg pills $138.00 but it left us with an untenable 57 degrees between the down tube and seat tube, methotrexate 2.5mg pills $138.00 which effectively ruled out any available lugged BB shell. Methotrexate 2.5mg pills $138.00 So, methotrexate 2.5mg pills $138.00 we chose to weld all the BB joints, methotrexate 2.5mg pills $138.00 and I just promised to keep it soft so it won’t look too out of place. Methotrexate 2.5mg pills $138.00

Methotrexate 2.5mg pills $138.00 Patricia chose the colors and layout, methotrexate 2.5mg pills $138.00 and all I can say is I approve.

Methotrexate 2.5mg pills $138.00 Now, methotrexate 2.5mg pills $138.00 that was the start of a small frame – let’s look at one from back in the archives…

Methotrexate 2.5mg pills $138.00 DESTRUCTIVE TESTING

Methotrexate 2.5mg pills $138.00 We don’t have the budget to do a lot of destructive testing, methotrexate 2.5mg pills $138.00 which is why we tend to stick with what we know. Methotrexate 2.5mg pills $138.00 Fortunately, methotrexate 2.5mg pills $138.00 we have friends who are badass racer-types and every once in a while, methotrexate 2.5mg pills $138.00 one of these friends gets in a scrape. Methotrexate 2.5mg pills $138.00 Liane was in the middle of a pileup on her nearly ten-year-old Cirlce A (pre-stainless head badge!) and this was the result:

Methotrexate 2.5mg pills $138.00 Most important to note, methotrexate 2.5mg pills $138.00 not only did she walk away, methotrexate 2.5mg pills $138.00 she attempted to ride away. Methotrexate 2.5mg pills $138.00 Then her front wheel hit the down tube… well. Methotrexate 2.5mg pills $138.00 At first blush, methotrexate 2.5mg pills $138.00 you might think this is a terrible thing for a builder to see. Methotrexate 2.5mg pills $138.00 But actually, methotrexate 2.5mg pills $138.00 it’s a great study in frame building, methotrexate 2.5mg pills $138.00 stress risers, methotrexate 2.5mg pills $138.00 and why we love steel.

Methotrexate 2.5mg pills $138.00 First, methotrexate 2.5mg pills $138.00 let’s note that this was a serious, methotrexate 2.5mg pills $138.00 catastrophic impact. Methotrexate 2.5mg pills $138.00 Clearly the front triangle has buckled in several places, methotrexate 2.5mg pills $138.00 but perhaps not clear from the pictures is that the fork is bent as well; the blades are bent slightly back, methotrexate 2.5mg pills $138.00 and the steerer is bent a touch at the crown. Methotrexate 2.5mg pills $138.00 But what’s really interesting is what happened to the frame. Methotrexate 2.5mg pills $138.00

Methotrexate 2.5mg pills $138.00 For the builder, methotrexate 2.5mg pills $138.00 the best thing is that Liane walked away. Methotrexate 2.5mg pills $138.00 The second best thing is that it didn’t break at a joint. Methotrexate 2.5mg pills $138.00 In other words, methotrexate 2.5mg pills $138.00 the forces applied to the frame were transferred from the wheel, methotrexate 2.5mg pills $138.00 through the fork and into the front triangle of the frame – which is what happens every time you get on a bike – and in this extreme situation, methotrexate 2.5mg pills $138.00 when those forces achieved a moment that was beyond what the frame could handle. Methotrexate 2.5mg pills $138.00 it sort of broke all over. Methotrexate 2.5mg pills $138.00

Methotrexate 2.5mg pills $138.00 It’s a study in stress risers; see how the top tube buckled at the cable stop, methotrexate 2.5mg pills $138.00 and the down tube at the shifter boss and the BB lug. Methotrexate 2.5mg pills $138.00 Then you have the buckling in the down tube – exactly in the middle of the tube. Methotrexate 2.5mg pills $138.00 In other words, methotrexate 2.5mg pills $138.00 it was trying to bend, methotrexate 2.5mg pills $138.00 but eventually the center could not hold. Methotrexate 2.5mg pills $138.00

Methotrexate 2.5mg pills $138.00 This is what happens with well made, methotrexate 2.5mg pills $138.00 lightweight bikes. Methotrexate 2.5mg pills $138.00 They can break. Methotrexate 2.5mg pills $138.00 But they will usually not break at a lug (even a minimalist, methotrexate 2.5mg pills $138.00 bikini lug as seen here), methotrexate 2.5mg pills $138.00 at a fillet or at a weld. Methotrexate 2.5mg pills $138.00 And, methotrexate 2.5mg pills $138.00 unlike aluminum or carbon, methotrexate 2.5mg pills $138.00 we can fix it. Methotrexate 2.5mg pills $138.00 As I do here.

Methotrexate 2.5mg pills $138.00 With a silver brazed frame, methotrexate 2.5mg pills $138.00 relatively little heat is used to join the lugs and tubes. Methotrexate 2.5mg pills $138.00 So, methotrexate 2.5mg pills $138.00 you generally have the option of heating the joint and pulling the tube out, methotrexate 2.5mg pills $138.00 or cutting and grinding it out. Methotrexate 2.5mg pills $138.00 In the case of a full front triangle, methotrexate 2.5mg pills $138.00 I generally will pull the top tube out of the seat lug, methotrexate 2.5mg pills $138.00 but I like to grind out the dt from the bb. Methotrexate 2.5mg pills $138.00 This is mostly because there is so much mass at the BB, methotrexate 2.5mg pills $138.00 it takes a lot of heat on all four joints there. Methotrexate 2.5mg pills $138.00 In general we like to keep the heat cycles down, methotrexate 2.5mg pills $138.00 but this is more important in a high stress area like the bb as opposed to the seat collar. Methotrexate 2.5mg pills $138.00 When was the last time you saw a bike break at the seat lug? Ok, methotrexate 2.5mg pills $138.00 so here’s work on the BB shell:

Methotrexate 2.5mg pills $138.00

  

Methotrexate 2.5mg pills $138.00 For the seat lug, methotrexate 2.5mg pills $138.00 I cut the center of the tube out and use a bungee cord to pull it straight out. Methotrexate 2.5mg pills $138.00 This helps keep the seat lug in shape; pulling by hand or trying to twist it out can distort the hot metal. Methotrexate 2.5mg pills $138.00

Methotrexate 2.5mg pills $138.00

 

Methotrexate 2.5mg pills $138.00 Note the shadow of silver on the top tube in the shape of the lug. Methotrexate 2.5mg pills $138.00 This is what we in the frame building industry refer to as full penetration. Methotrexate 2.5mg pills $138.00 In other industries this might mean something else.

Methotrexate 2.5mg pills $138.00 Anyway, methotrexate 2.5mg pills $138.00 here’s the (re) finished product:
