  1. they are difficult to find on PMW the site because they make sliders, dropouts, and inserts. I've owned two frames with inserts like that- Vassago and Soma. (I think US-made Vassago frames like the Verhauen used genuine PMW sliders/inserts, but the Jabberwocky was a bit cheaper by using generic sliders and inserts.) I think both used IRD sliders, which are basically the same thing as the PMW sliders. they are not a perfect match, but they should work interchangeably. PMW will tell you they are not the same thing, but that's mostly because they want you to buy their product, but also because they are not exactly the same thing, even if they work together.
  2. Are these what you need? https://www.paragonmachineworks.com/catalog/product/view/id/3506/s/12-mm-left-side-insert-for-sliding-dropout-post-mount-160-rotor-choose-color/category/482/ https://www.paragonmachineworks.com/catalog/product/view/id/3514/s/12-mm-right-side-insert-for-sliding-dropout-no-hanger-choose-color/category/482/ Look under "adjustable dropouts"
  3. I would ask Paragon, but 142/135 should be interchangeable. Switching them to 148mm is unlikely to work, though.

    I have some of those and I hate them. see my DIY foam organizer above. I'm almost finished with it.

    the Habitat for Humanity ReStore on South First always has a ton of cabinets for cheap. go straight to the back of the store to find them.
  6. Gravel route today resulted in soggy shoes after several creek crossing along Slaughter Creek that had more than 12" of flowing water. So yeah, SATN is not good to go.

    I bought this set of four interlocking floor mats for <$10 at Harbor Freight. they're about 10mm thick. they're just the right size to be cut in half and trimmed down to fit in the drawers and I'll have a few extras. Here's the SAE drawer. I drew one line with a yard stick along the bottom and started laying out the sockets with even spacing. it's not perfectly square, but it's close enough. I mapped them out on the "back" of the mat so it will look clean when I flip it over. I have some space left over, which might hold some hex keys or something: I've cut out about half of the the socket pockets. this took some trial and error, but I found this to work: put the box that the toolbox came in on a table top. it's four layers of cardboard so you can jab straight through and not worry about dulling the knife on the tabletop or scratching up the surface. extend utility knife blade all the way out (about 1") and start jabbing. cutting out each square takes a steady hand, but you can kind of saw through it to keep from sliding and slicing too far. flip the mat over and carefully cut out the rest of each square nice and clean. ^this socket fits perfectly in this spot. when I flip the mat over, it looks like this: bonus tip: for the very small sockets, cut the hole out about 150% of the length of the socket. they way, you can fit your finger behind the end of the socket to pry it out. you don't want the fit to be too tight so that the sockets fall in and are a challenge to dig out of the pocket.

    Finally broke down and bought this Craftsman toolbox. $100 with tax at Lowes. Seems like a relatively solid deal and has more than enough room. Now all my sockets are rolling around in the drawers though. Need to visit Michael's to get some foam to cut out an organizer.
  9. I will visit the office next Friday, but otherwise it's all WFH. DM me later in the week to remind me to bring those.
  10. Bontrager XR4 tires, 29x2.4 TLR Kenda Flintridge 700x40. casing has a wobble. you won't feel it when riding, but if the frame has limited clearance, it might rub. Conti X-King, 29x2.2? missing one knob Felt TT saddle Sp[ecialized ergo drop bar Specialized Butcher 29x2.3
  11. there's no actual maximum tire width (within reason) that you can use on any rim. of course, a 5" fat bike wide tire on a 15mm wide road rim would cause problems, but a 2.8" tire is not going to blow off a Flow rim. it might not provide optimal handling and feel, but it will work. what's the inner width of that rim? the original Flows were, what, 25 or 26mm wide inside?
  12. my last bike shop job had a FULL box of these rear rack struts. I could make something out of two of these that would allow the sensor to slide along the bar, and slide horizontally perpendicular to the bar as well.
  13. I thought about that, but the holes are too far apart to make them line up with the rim that your are using as a reference point. the measuring tool needs to have more adjustment along the tool.
  14. I made a derailer hanger alignment tool cheap. Here's how you can make one too: 1" punched square tube, 36" long $15.52 at Home Depot 887480030372 M10-1.0 x 60 mm bolt $3.90 at Home Depot 570032 M10-1.0 nuts X2, $0.65 each 598980 10mm or 3/8" washers. I used five. use whatever you want as spacers. for less than $30, you can make two of these and give one to a friend, because the 1" punched square tube is twice as long as you need. the process is simple: cut the square tube to half its length. 18" is more than enough. drill out two holes at one end of the tube for the 10mm bolt. the 3/8" holes are a tiny bit too small for it. a 25/64" drill bit or 13/32" should do it. slip a washer onto the bolt and slide the bolt into the widened hole. slide some washers/ spacers onto the bolt until the non-threaded part (if the bolt you chose has a non-threaded segment) is covered thread on a nut until snug. thread on a second nut and tighten it against the first one. this is just like setting up the cone nut/ lock nut on a bicycle axle. get it tight enough that the bolt can rotate inside the tube, but with minimal play. Now you have a functioning DIY DAG tool, but at about 1/5 the cost. follow the basic instructions for the DAG tool, but use a ruler held perpendicular to the tool to get the hanger within 1/8" or alignment. possible improvements: if you can find a way to thread the bolt into the hanger with a larger, hand-friendly interface, that would be ideal. right now, my plan is to use a wrench on the bolt head. not a big deal but it would make it more ergonomic. "hold a ruler perpendicular to the tube" is not precision! it will get you closer than just guessing, but if someone can think of a way to attach a metal item to this that would allow it to slide and be fixed in place as a reference point, that would be ideal. I'm open to suggestions. If this design works, feel free to make it for yourself! I will keep improving the design and, if there's demand from people who don't want to bother, I'll make them and sell them for a little more than what the parts cost me. the Park tool costs a lot more and is currently out of stock. I would not trust this in an actual bike shop, but you can use this at home and throw it in your car when you drive to a ride for emergency fixes. *bonus info* you should probably check most new derailer hangers for alignment when you install them. on some frames with precision machined hangers, this might not be needed. but on older and cheaper bikes with flimsy hangers, installing a new hanger after you bend the old does one does not guarantee that the new one will be anywhere near straight enough to support adequate shifting.
  15. Just saying: I've been using the terms "effective reach" and "effective stack," and trying to get people to think in terms of RAD/ spread/ room/ effective down tube in the same context for years. Since no one lists EDT on bikes, I have an old spreadsheet comparing several frames I was considering at the time, partially based on calculating the EDT as a starting point. I have bike fit paperwork from 2017 where I had Frank at ATX Bike label the "eR" and "eS" on my fit labeled. Glad to see it's finally catching on. Saddle-handlebar drop is indeed mostly poppycock. Hot take: Most people have their handlebar too high so they can sit up high and pretty like a beach cruiser. Take that or leave it. But if you ride with me and I smoke you on a climb, it's not all the fiber in my diet that's doing the work. Maybe the farting gives me a boost. I can't seem to get my handlebar low enough to be confidence-inspiring!
  16. yup, saw that and realized once again that the SQLabs 12° on my bike for the past three years has no need for improvement. it works for me in ways that a sweepier or staight-er bar would not. YMMV.
  17. that got nerdy real quick. suffice it to say, term does not derive from golf slang when applied to programming skill and using the same word to describe the same thing is a fun way to confuse someone, but a poor way to communicate. if someone has any sort of skill at solving programming problems, they are a "hacker" and probably wear that title with pride. if you're bad at golf or some other physical, non-programming skill, you might be a hacker in a negative sense. that history is a fun rabbit hole that is not difficult to find if you want to dig in.
  18. that's a new one to me. I've literally never heard the word "hacker" used in that context. that's either archaic or a neoquialism so fresh that it's not crossed my path yet. one can be a hack (noun) at hacking (verb) and apparently, a hacker (adjective) of a hacker (noun).
  19. I think that's the difference between a "hacker" and just a "hack." hackers are defined by their skill, hacks by the lack of skill.
  20. are you concerned that they are going to send you payment, accept the item being sold, then claim that you didn't send it or something and get a refund? that's very possible. I sold a bike a few years ago for $700. the buyer wanted to pay me electronically as she didn't feel safe carrying that much cash to meet a stranger in a dark HEB parking lot. (that's a relatively safe public place and the only time our work scheduled allowed us to meet.) I told her I could not accept Paypal or anything like that because of the scenario above, so we made cash work. she was surprised to hear that people can scam each other that easily with electronic payments and I said "that's the world we live in now." I've sold some frames online and it was always scary to know I could lose a few hundred bucks that way. You're correct to we worried.
  21. Anyone know a teacher(s) who works with grades 6–8? I need a consult on a work-related project.
  22. $99 Roadmaster POS with sketchy motor, seen on FB group:
  23. when i was a mechanic, I usually offered a few levels of service for every bike that came it. I can make your bike safe and functional, or I can make it as close to "like new" as possible. going 110% was not necessary for every customer, but many were happy to do everything because they only take their bike in once every few years. that's the way it should be.
