Time for real TT bike vs. being required to use a road bike for the juniors.

TTT this weekend in SoCal. ITT in two more weeks. Nationals super flat in Tahoe in June and about 4 Euro ones coming up (don't know what equipment yet for that) in July.

I finally retired the Mavic Mektronic 9 speed that has been used for some 20 years of TTs. New Di2 9000 on the rear 11 speed. But using the Zipp that takes only 10 speed cluster. By using the Miche Supertype cassette with only 10 cogs (it comes with 11) it fits great with a spacer. Then blocking out one gear with the rear adjusters it shifts 10 speeds with 11 speed spacing. Spacing between 10 and 11 is so close anyway a 10speed cassette would have worked, just that for a TT - I didn't wans that little drag from less than a perfect alignment.

Part II:
On his old cassette we turned off the last two cogs so his smallest cog was in the 3rd position (1 being smallest). This kept the chain aligned with the big ring better than the normal setup.

Part III:
Thinking of the front going to a real big ring. Too late now to mess with it, but could be a end of season project.
A larger ring/larger cog has less tension on the chain. I can flip cog positions on this cassette on all but the 14T. We may put the 15 in the 3-4 position and grind down the 14T (junior gear restrictions).
It also scares the competition.
