One of our strength compare to "big" companies is to be able to offer custom products. Of course, you have to understand that this is not a one day process.
First of all we have to gather information about the crank you are using. Also information’s about the application of the chainring is very useful (MTB, Road bike, for gravel race, time trial, track ...)
From this point we will start drawing a project. Once the drawing is done, we are sending it to you for approval. Then we start producing a test chainring, using our days 3D printers. If all seems fine, we start producing the final item. Of course, multiple items are always cheaper, as we split all development work in 2,3 ... instead of 1.
Recently we've been asked to develop a special chainring for Campagnolo crank, with 135BCD and 54T. IT will be used by a sportsman for the next IRONMAN World Champ on 8th of October in Hawaii.
Here is the project on paper, one of the main requirement was to have longer tooth.
And here is how it look once finish. Good luck in Hawaii !!!
