Vittoria Rubin Pro

I have found the Rubin Pro’s are good for time trails and not a fan of using them for heavy cornering.

For using them racing the 23 mm, I like to have less then 1,500 km on them and for the 20 mm I like to have less then 800 km.

For max life span the 23 mm seam to be in the 2,500 to 3,000 km range and the 20 mm at 1,000 to 1,500 km. Keep in mind I am hard on my tires so your mileage may be better.

Michelin Pro Race

The Michelin Pro Race 23 mm and 20 mm have done fairly well in races. They grip well in dry and wet conditions. Good for cornering.

For using them racing the 23 mm, I like to have less then 1,500 km on them and for the 20 mm I like to have less then 1,000 km.

For max life span the 23 mm seam to be in the 3,000 to 3,500 km range and the 20 mm at 1,500 to 2,000 km. Keep in mind I am hard on my tires so your mileage may be better.

Ultegra Hub

Based on my experience with wearing out a couple Ultegra Hubs I have found them to roll smooth when new expect they wear out fairly quickly. When I say quickly, I mean noticeable difference with in 5,000 km. At 15,000 km I figure there is a 5 to 10 % energy loss. My feeling is my wet weather riding style does not vibe well with the hubs. Their weak point is the hub casing. Grease, bearings and holders can all be replaced but the casing still wears out.

Additionally, the cost of a replacement free wheel is close to the cost of the hub. Overall good if you are using them for less then 5,000 km / year and keep up on the maintenance. The would last two to three years.
