I don’t have any personal experience but have a coworker who likes his (F80) and have read some good things on this forum about these being a decent budget option.

I saw last years thread get bumped but figured we might as well make a new one for this year. Mods - feel free to add/edit things to this post if you want. I might try and pop in and add deals if I see them

Clothing:
Pactimo - 30-65% off
Pearl Izumi - 25% off
Castelli - 25% off
Asics - has a spot where you can sign up for Black Friday/Cyber Monday deal access which says is 30% off almost everything
Roka - seems like they have really shifted their focus to eyewear (which is on sale). But their wetsuits and swim skins are ~30% off
Huub - on the USA site they have a tiered sale (but 2 items, get 20% off, buy 3 get 30%, all the way up to 6 items and 60% off...code is 2for20, 3for30...etc)

Bikes

Quintana Roo - you also have probably seen the sidebar ad - sale on their bikes, frames, and wetsuits
Factor - fill out the form on the link for access for up to 40% off framesets or up to $1300 of builds…unfortunately not the Ostro or Hanzo :(

FLO - $200 off? (a pop-up when you click onto the site asks for an email to presumably get the code)

Non-Fitness Electronics:
Best Buy - great time to pick up a pain cave TV for pretty cheap. They also have Apple TV 4K (2nd gen) for $110 which is a decent cheap way to run Zwift (though per google it looks like Walmart has it for $100)

Looking for a deal on ultegra crank arm power meter (one sided).... Anyone see anything?

Anyone know of deals on Garmin Varia Radar? Without Camera? DC Rainmaker shows a normal sale price, but I'm interested in a true Black Friday deal.

Sure. We clean new chains, process them to smooth all the pins, plates and rollers, then wax them. Our wax also contains friction modifiers.

The micro surface process eliminates all the micro peaks thus extending both the life of the chain and reducing friction.

Here is an article:
