Pedals

Keo Sprint do well for training and Keo Ti Carbon are nice for racing.

The Keo Carbon Ti come race ready, they all ready have gone threw a test of load bearing rotations. The rotation is silky smooth.

One of my older Look pedals weight more then two of the Look Keo Carbon pedals. Very noticeable on the pedal stroke and well worth the extra $$.

For commuting I use greyhound track pedals with plastic clip ones from mec. They have a sealed bearing which does well for one winter. Salt and sand mixed together to a great job at braking down grease while wearing out any metal part.

Cassettes

I have run threw more cassettes that I can remember, ultegra has done well for training and so long as regular chain replacement is done they last 3 to 4 chains.

Lower end cassettes wear quicker and I tend only get 3 chains out of them.

I don’t ride much with dura ace cassettes, I doubt that the cassette would last longer then ultegra. If it did then it would need to wear 2x slower then ultegra to make it financially justifiable for training.

For racing, the extra weight loss is easily justified considering how difficult (costly) it is to reduce weight on wheels. Rotational weight is key during races with lots of spin ups.

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.
