I’ll happily stand up for Superstar Components.
I have a set of Superstar Components road wheels. The pair weigh less than 1500 grams (I weighed them) and cost less than £250. The Pacenti 23 rims failed after three years of riding so I contacted Superstar. They offered to rebuild them onto new rims for free if I bought the rims. I paid £80 for two rims and sent the wheels back to Superstar in the original box. They were rebuilt (straight and true with good spoke tension) and back in my hands within two weeks. They still weighed less than 1500 grams!
I also have some mountain bike wheels (Stans rims with Superstar hubs). They have been faultless. They’re set up tubeless and maintain good spoke tension and the bearings are showing no signs of notchiness or wear.
I’ve also just rebuilt a front wheel (my first go at this!) onto a Superstar hub.
I have faith in Superstar Components and I like the fact that they manufacture in the UK. Cost is good and quality appears at least as good as I expect it to be. Customer service has also been very good thus far.
