The Alexrims AT400 are standard equipment on my 2005 Bianchi Pista and they seem very strong. I ride the Pista through Baltimore City, Fells Point cobbles and they remain true. I also rode the Tour of Hope and around Wash. DC on the Pista without a problem.

I also own two sets of Mavic Cosmos wheels are they are very strong, reliable wheels.

I prefer Mavic wheels but I am impressed with the Alexrims AT400
