I build wheels for a living, from past experience I have shared plenty of knowledge with people. A couple of them decided to start their own wheelbuilding brands as a hobby subsidised by their day jobs, they also got in touch with a few of the brands that I regularly built for and offered to supply them at a cheaper rate than me. Thankfully I had loyal clients that let me know and continued to work with me knowing that this was my only income.
Due to this, I tend not to discuss my process with anyone.
Some of the reason that wheelbuilders charge what they do is overheads, cost of tools and the upkeep of them (recalibration of tensiometers etc) and the price of public liability insurance. Also some wheels only get built after a lengthy discussion with the client, 10-20 emails maybe. This is all time that needs to be charged for. Usually rim tapes/tubeless tape is included in build labour too. There is also the time taken to measure all parts and calculate spoke lengths. We cut and thread spokes in-house to 0.5mm increments for more precision, off the shelf spokes are usually available in 2mm increments.
I encourage people to do as much stuff themselves as they can and be self sufficient, you don’t need the best/most expensive tools out there to do a great job.
But I feel that lots of people think that we overcharge without considering the aspects I’ve previously mentioned.
Sorry! Haha. Rant over!
