I have always found superstar kit reasonably priced and pretty good at what it does….
Their customer service has been OK for me in the past.

Anyone have any opinions on these wheels? £450 seems a bargain for carbon hoops with 2 year warranty, lifetime truing and decent crash replacement policy. ~1720g for 650b so not that light. I guess the benefit is in stiffness and width of the rim.

Anyone know how easy it is to switch between XD and 10 speed drivers?

Yeah great CS when you are a perspective buyer of their kit to try phoning then have phone slammed down on you!
