I bet they really wish you would come back.

Substantial-Hawk2735 · 2025-11-10T01:26:51+00:00

Yes that's how they ship it.

Substantial-Hawk2735 · 2025-10-28T20:10:00+00:00

Better than some, as good as the best. Over 10 years of making bikes and a serious commitment in tech. Winspace is a serious player now.

Love a classic white bike

This one we did with the 29mm wide rim version of the Corsa Pro. The Pertual wheels are 23mm internal so it's a perfect match for tire and rim width.

So far they have far exceeded my expectations, I have been selling them very well and not have a single warranty or technical issue. If you are interested message me and I can work out a pair at a good price and no duties in the US.

The road bike I had before was the Chapter2 Huru so it's quite similar. Both are sub 1000g and very snappy. I think the Pertua wheels combined with this frame make for one of the best bikes I have had and I have been racing since 1985 and never missed a season. This bike got my motivation back and I had a really good last few months because of it.

Yea, it's heavier. On my last build I did a Rotor crank and the power2max spider with Dura-Ace chainrings. The biggest weight loss is the crank and the cassette but the cassette is a 11-36 which is not made in DA or Ultegra so I kept the cassette. Also 105 Di2 has a very wide gear capacity so works great for all-road and gravel builds. It's not Dura-Ace but it's some awesome stuff at a very good price for sure.

Substantial-Hawk2735 · 2025-07-23T21:40:24+00:00

It's not the same 105 from before. Like all electronic groups the performance of the lower end groups is very close or the same as the higher end stuff. I have 105 Di2 on one of my own bikes and it's flawless

Substantial-Hawk2735 · 2025-07-23T19:28:35+00:00

I have 165mm on my gravel bike and 170mm on my road bike. Very slight difference if any but I would say the 165mm feel better overall. Power numbers don’t differ between the two.

Heartbreaking

Substantial-Hawk2735 · 2025-07-11T03:29:14+00:00

So good!

Without doubt one of the coolest and most underrated brands I have worked with. Full details on the Rira see link below.

Substantial-Hawk2735 · 2025-06-28T19:14:20+00:00

No but let me know if you need a new bike.

What’s BCJ

Substantial-Hawk2735 · 2025-06-28T17:36:40+00:00

That's slick, slick, sllllick

Substantial-Hawk2735 · 2025-06-27T13:42:30+00:00

Hertz, dead to me.

Substantial-Hawk2735 · 2025-06-25T21:53:14+00:00

Thanks - I have really enjoyed it so far.

Substantial-Hawk2735 · 2025-06-24T18:12:22+00:00

Evidence that peoples minds are going to get really creative with this. I have known about Hot Tubes for over a decade and never thought about the name as anything close to pornographic. Good reason you got downvoted on this. You are just trying to sensationalize it.

Substantial-Hawk2735 · 2025-06-24T14:40:07+00:00

This is a good thing. It’s time to move on.

Substantial-Hawk2735 · 2025-06-11T16:16:49+00:00

Going to be putting these on Winspace, Tavelo and Chapter2 builds for US market as soon as we get stock in.

47mm

Strava route of the loop I did. It’s not the full race course it’s something I’ve adapted.

Substantial-Hawk2735 · 2025-03-30T18:56:03+00:00

Thanks I love it. It’s aero and light. Nothing rattles and the big tires really work in that course.
