I am surprised how fast the Halo bikes seem to be on something like 4x Loch Loop! Even Tron bike seems to be faster than high-performer frames. I should probably change my strategy with bike upgrades 
It’s a Halo bike, so the Halo bike filter need to be selected. Also, they cost 10M drops, so you need to pull the drops slider all the way to max.
@Thor_Gabrielsen Hi Thor, hoping you’ll see this 
I’m a part of a small international Zwift cycling team (about 12 women) who race the WTRL Thursday TTT together each week. I help my team run our own small and private website.
I’d love to ask your permission for something.
I’d like to reference your bike and wheel data to show course-specific setup recommendations on our internal team site, so when a rider opens an upcoming race, they’d see a small “recommended setup” drawing on ZwifterBikes data, with a clear “Powered by ZwifterBikes” credit and link to the full tool on your site.
A few things I want to be upfront about:
- The site is private and behind a login, only our team sees it, not commercial in any way.
- I’d happily credit you prominently and link out for the full analysis on every recommendation.
- If you’d prefer I just deep-link to your route pages rather than reference any data, that works too - whichever you prefer.
I really don’t want to add any hassle. If it’s a no, completely fine.
Whatever way works best for you, I’ll follow. And either way - thank you for keeping ZwifterBikes going. It is a huge amount of work you do, and I’m sure all of us zwift-riders really appreciate it!
You can see the site at amicisteam. com (it’s login-protected, but our privacy policy is public)
Best,
Ruth-Anne
Hi Ruth-Anne,
Happy with that 
While I have put a lot of work into calculating the fastest bike for each course, the results reflect an ideal scenario, so treat them as a starting point. Race dynamics, individual tactics, and the course profile—especially near the finish—should also be taken into account when choosing a bike.
Regards,
Thor
Plenty of latitude with drafting, power-ups, and compressed wattage (riding 20 watts higher than average on climbs and 20 watts lower than average on flats).
I’m most amazed at how small a difference there is in wheels. Should I buy wheels that will save me 1.5 seconds on the Alp? Doubtful.
Thanks so much, Thor - I really appreciate it! 
And thanks for the helpful context too.We’ll present it as a starting point on our site, with a clear link back to zwifterbikes.web.app so riders can run their own numbers.
Thanks again 
@Zee_Kryder - thanks for pointing those out, definitely useful context to have in mind
