Looking to buy a 2021 Evil Wreckoning frame, size Medium, somewhere in Colorado. I'm in Boulder but willing to drive somewhere to meet up. Float X2 shock preferred, but will consider bikes with a coil shock. Not really concerned about the frame color (Coral Reefer or Black), Coral Reefer frame was just the first photo I found online. $3000 if the frame is in excellent shape with a factory Float X2. By excellent, I mean one could hardly tell it was not straight from the shop. I'm interested in frames in good, great, or excellent condition. Thanks for looking and let me know what you have!

Commencal Announces 2021 Meta HT AM Hardtail
@kirchenschlager: I’m not singletrackman but perhaps I can answer your question. Reach is the length of a line (call it A) drawn horizontally from the top-center of the head tube back to where that line intersects with another line (call it B) which is drawn vertically from the center of the BB. As the fork compresses the frame rotates around the rear axle, so every point on the frame must move on an arc which is centered on the rear axle. So if a point on the frame is vertically above the rear axle, it first moves forward then down for example. Since the head tube is above the rear axle, it moves forward and downward. The BB which is below the rear axle, rotates downward and rearward. This movement causes the start of line A to move forward while the vertical line B moves rearward, so the length of line A from the head tube to the intersection with line B grows. The reach growing is true even if your BB is above the rear axle, but I don’t want to get too into the nitty gritty. Hopefully the above explanation helps clarify this geometry change with front fork compression. A visual would certainly help and may be available on the internet somewhere.

Raceface Turbine Crankset, 170mm length. These cranks are brand new. They were installed in my bike for about 2 minutes, just enough time for me to realize they did not fit because the spindle was not long enough. I never even installed pedals. These are great cranks and I wish I could run them but I can't really make my BB any narrower, so have to let them go. Because they were installed, there are small marks where they were pushed through my BB, but that is the only wear. I've done my best to picture these marks, but they are very faint so they don't show up much in photos. I also have a blue, 32 tooth Raceface Cinch chainring that I will include with these cranks unless you don't want it. It was used for a few rides (on a different set of cranks) before I realized that Shimano 12 speed required a special chainring. Below are links to a couple reviews of these cranks, in case you have any questions: https://www.worldwidecyclery.com/blogs/worldwide-cyclery-blog/race-face-turbine-crankset-review https://www.pinkbike.com/news/race-face-cinch-turbine-cranks-review-2014.html I’m getting a lot of questions about shipping even though I posted as Local Pickup Only. I will not ship these cranks, if I change my mind about that, I will change the ad.

Dropped price because I sold the second set of wheels. For sale is my 2017 Specialized P.3 Pro with two sets of wheels. I started riding BMX about a year ago and haven't used this bike since. It is in good condition, with some minor abrasions to the downtube, and a few paint nicks on the frame. I've tried to picture all of this in the photos, but let me know if you want specific photos of any part of the bike. The bike has Spank Tweet 28 hoops on DMR hubs. I have the front brake and rotor, and will include them with the sale of the bike. If you would like, I can install the front brake with the hose routed through the steerer tube, or provide the parts for you to do this yourself. Let me know if you have any questions. I am flexible on the price, but I'm not in a hurry to sell. I'm interested in trading for a size medium or large 27.5 Pivot Firebird in good condition (proper suspension, solid wheels, and functioning dropper post), plus cash from me, to make up a reasonable difference, otherwise I'm not really interested in a trade.
