Subrosa Malum and Letum complete bikes are now in stock. All sizes!

The big upgrade for the Malum 3 piece bmx cranks with a splined spider and better stem/bar.

The Letum uses the same frame with less expensive parts and is just $525!

These are the prototype box section rim from H+Son. Laced up to All-City hubs, they will definitely be getting some miles in this week.

Josh came out to the races last night and took some photos. Unfortunately the threat of rain kept turn out to a minimum yet again. It was still really fun as usual though.

H+Son has been working on a super low profile clincher rim for some time.

This was in my in-box when I woke up this morning:

Hello fellow distributors and dealers,
After a few months of waiting I am coming close to the completion of the new rim. I still cannot send samples out yet because we are still making the valve plate for the rim. Kind of like a head badge for a rim if you will. But here is a quick look.
The profile is 14mm high and is 23mm wide. This makes it look slightly fatty, but as I have stated before this is a new clincher rim standard that has been adopted by Sram/Zipp, HED and countless others drinking the wide rim Kool Aide.
Copy pulled from the HED website about the new 23mm rims
“But what makes 23mm better than the ubiquitous 19mm rim? Width. Picture a standard 23mm tire on the C2 rim. Tire and rim width are the same, the sidewalls are fairly straight, and the width of the rim spreads the tread contact patch out. With straighter sidewalls, and more rubber on the road, cornering is an entirely new experience. The sidewalls don’t flop over in a hard corner, and more rubber on the road is, well… better. C2s should be run with lower pressure, since there is more air volume in the wider tire profile. The same tire on a 19mm rim looks more like the profile of a light bulb. The curved sidewalls flop over under hard cornering, there is less rubber on the road, and more air pressure is needed to prevent pinch flats.”

I think this rim will look great on classic builds regardless of road bikes, track bikes or even touring/rando bikes. And the wider profile makes for a much better ride with a more laterally stiff wheel. The only problem being the shallow depth of the rim takes away from radial strength which is why i recommend this rim to be laced only to 32 and 36h hubs.
I am also considering a 2nd rim like this with more depth and going for the Mavic open pro market and offering a lower spoke count.

I plan on offering it as a high polished rim or a hard ano with machined sidewalls.
Please let me know what you guys think about the rim. Thanks!

A sample pair is coming my way to build up and test out.

As you can see this has more than a passing resemblance to super low-pro tubular rims like the ones Araya still makes. The wider profile should give it a more tubular like ride as well.

Looking forward to building the up.

The Pamparius Pizza Blog / Carytown Bikes Pizza Crawl is coming back at the end of the month. Last time it was the best and worst of Richmond Pizza. This time its all the cream of the crop. Details to come but this year Jim from Barf Comics is hooking up a sick t-shirt.

The design is still getting tweaked but here is the first sketch…
