Off to try the local club 10 mile TT segment this afternoon and have a quick question which will probably be answered more quickly in here than in the TT thread...

I understand how to pace the 10 miles etc etc but my question is more about riding a TT to power and whether it's quicker/more efficient to:

  • Maintain threshold and blow up whilst crossing the line
  • Average threshold and blow up whilst crossing the line (i.e - cross threshold for the climbs and recover on the descents)
  • It makes no difference :o
  • Pancake :eek:
  • Buy another bike :p

Logic is telling me averaging set power makes the most sense but I am on a Monday brain derp potato today.

I think the right answer is it depends and course knowledge plays a part. Generally the steeper the hill the harder I push assuming a descent to recover on the other side. Averaging threshold is the way forward but may necessitate pushing quite hard in between roundabouts/junctions etc which will reduce your average but give you chance to recover.
 
Bit of a close encounter with a van this morning who insisted on squeezing past me at a pinch point while speeding. He had a "Think bike" sticker on the back :rolleyes:
 
If anyone is getting into their TTing, I am looking to get rid of a 2014 Kask Bambino size M if you know what I mean.;)

*hides from FT*
 
I'm thinking about it, lots of local TT's here and lots of local guys so always some spare kit/bars/frames floating around...!

To be honest now my house stuff is sorted I really need to tweak the new ride & get out on more group rides after work. Once I'm outputting good power again I'll be wanting to attempt some 10's! :)

Thanks :)

Madindehead, you might not have seen this if you've not checked but Wahoo have added juicy metrics to the activities section within the App for the Elemnt with the latest firmware update:

Unfortunately, the Bambino size M is for 55-58cm heads!
 
If TTing should always try to squeeze your head into the smallest helmet possible! Don't worry about comfort.

See, I mostly knew this but hadn't really appreciated the slim margins once over 20 mph.

The increase in power is related to the speed^3 so the faster you go, the greater difference in power you require, all things remaining constant.

I was wondering about that the other day, as I was noticing that I needed a huge amount of power to increase my speed by even a couple of miles an hour, or when I went up even the slightest incline.

It's very interesting seeing the numbers in front of you when you're riding.
 
Gripper paste on a carbon seat post in an aluminium frame, talk to me.

Read mixed things but the general consensus is it's fine and a periodic removal & clean to stop any permanent sticking is recommended?
 
another question on a tangent, sorry.

my BMC GF02 came with 160mm disc brakes. Will there be any issues if I replace these with 140mm?
Do some frames only accept 160mm?

depends on how the caliper is mounted, there are adapters to go to bigger sizes, but once you're mounted directly to the frame, that's typically as small as you can go
