Newsonsportec bike rims

grabcad

A set of five different sized bike rims, ISO 349 (Brompton 16"), 355 (18"), 406 (20" BMX), 559 (MTB 26") and 622 (28"/700C) I made a simple basic file with the rim section profile, added an axis to perform revolve and defined the size of the rim with a simple single dimension change. It can also be done as a set of configurations but I prefer to have separate files of smaller size. The planes to create spokes and mate with a hub are included in the files. The section drawing and the dimension that has to be modified to get a different rim size is shown on the screenshot. To get the desired size, just type the overall bead diameter slash two (eg 559/2) and hit enter, exit the sketch and save. Once the part file is saved in STEP format, that sort of change is not likely to be made, so I packed all the five sizes into a single archive file. For reference I used the files from: http://www.newsonsportec.com/rim-bike.html All rims come with the same 32H configuration and a valve hole drilled. I really hope someone will like it and/or find it useful ;)
