I have it on live for the last 5 mins and haven't heard him ahead of GT splits? Assume he is by your post so will now have to pay more attention - in fact as I type, have just heard his name whilst signing some docs.... who said an idiot male monkey couldn't multi task? :smile:

He was 20 seconds quicker than Thomas at the first split.

He was 20 seconds quicker than Thomas at the first split.

Even quicker now.... But GT has grabbed a decent chunk of time back from that fall? Only 3 mins+ to grab back now for a podium?

I take from the lack of jumping up and down, and calling it a farce, that none of the fallers today were Brits? :laugh:

Comfy armchair to one person & a plank to the next
Landa cross chaining up those hills (big ring, big sprocket)

Suppose it's fine if it's not your bike
Not really - drivetrain efficiency usually takes a hit from crosschaining and it's not enough to overcome the benefit of using larger sprockets. See the attached graph from Human Power 52, for an example of how the wrong derailleur gear can hurt:

Edit: The gear numbers are translated in the article as (1) 22/34; (3) 22/26; (4) 32/34; (7) 22/20; (9) 32/26; (10) 44/34; (11) 22/16; (15) 32/20; (16) 44/26; (18) 22/12; (20) 32/16; (21) 44/20; (24) 32/12; (25) 44/16; and (27) 44/12. So (18) is small-small with (16) as its nearest tested big ring gear and (20) the nearest middle; and (10) is big-big with (11) its nearest small ring gear and (9) the nearest middle. Which does what I expect for small-small but nearly the opposite for big-big although there's not really much to choose between (10) and (11) and the next shift down from (11) would be (7) which is much better than the neighbouring middle-ring gears. I hate derailleurs! Anyone seen a similar chart for a modern double-ring setup? :laugh:
