SRAMgnam Cyclocross Style

After a Cross season that wasn’t, this makes me feel worse – boo! They’re in such good shape with no injuries, they can dance around SRAMgnam Cyclocross Style!

It is good to see that serious racer crowd having fun though. While they shot these, we were relaxing and riding in HNL.

Tiso 12 Speed Group

Tiso picked 12/12/12 to announce their new 12 speed, wireless electronic group and if the soundtrack to the video is any indication of well it works; well, then it’s awesome! Props too for another group to compete with Shimano, SRAM, and Campy.

Shifting operation is controlled via a wireless radio and/or wireless bluetooth signal. Commands are activated using buttons integrated into the brake levers. The cassette sprockets are made of titanium and weigh about 150 grams, despite having that extra 12th sprocket (11-29). The derailleurs utilizes a micromotor with encoder for the operation and control; the unit is powered by AAA batteries.

I saw some of Tiso’s kit at Interbike and it’s all very nicely machined. This group works with Campagnolo, Shimano and SRAM.

Rando Mode Part 1: the Fork

A few days ago I talked about adding a “rando mode” to my multi-modal travel bike. Byron and I have often discussed the concept of having a bike frame that could be optimized for different uses by swapping out components like handlebar/shifters, cranks, or maybe forks. Those components would use the same quick-connect fittings that are commonly used on bikes incorporating S&S couplings. Actually, S&S-fitted travel bikes are the ideal foundation for a modal bike, combining a “go-anywhere” option to the “do-anything” flexibility.

The modal bike concept is something I have been refining since 2004. I first started thinking about this randonneur conversion for my already existing modal bike back in June this year, and it was only this week that I finally got the last few adjustments spot on. After the photo and the jump, the project starts with the custom steel fork and Nitto rack.

Huggcast Shorts: Dynohub

In this short, a dynohub from Biologic is seen. This setup is used to charge an iPhone case with a battery. Next, I’ll use it the dyno to run lights on my urban bikes all the time. Just like daytime running lights on a car and headlights at night. It’s ridiculous really to have a 1200 lumens light last about 50 minutes on a rechargeable battery. Even more ridiculous design wise, is all the devices attached to a bike that require recharging when I can generate power with next-gen hubs like the Joule.

What About Wheel Size with Alex Moulton

Dr. Moulton

Dr. Moulton’s Spaceframe Bicycle

I had an audience with Dr. Moulton once. It was an honor and a pleasure. Besides the history lesson of the brand and desire for recognition of his legacy, Alex wanted to talk to me about Jan Heine. Jan had written a critical review of Moultons after crashing on one and Alex felt he had been dissed. The politics of that article, I’ll leave to Moulton’s heirs and Jan, but I got schooled in high-pressure, small-wheeled tires with full suspension by the good doctor himself. As a proxy for Jan, I heard a very strong argument against low-pressure, 650b tires and how more cyclists should’ve ridden suspended bikes. Alex believed he’d found the bike design holy grail: horizontal stiffness and vertical compliance. He figured out, with suspension, how to propel a cyclist comfortably forward with an efficient drivetrain. The bikes I rode at his estate were Rolls Royce smooth with a bottom bracket that didn’t move. The space frame from Moulton was revolutionary, but as history showed, few noticed compared to traditional, double-diamond frames.

In honor of Moulton’s contribution to the bike, below is an edit of video taken during our meeting. In it, Dr. Moulton explains how his work on the original Mini, a small-wheeled car, led to the spaceframe bicycle. He also wanted to design a bike without a top tube to prevent accidents and make stepping onto and off the bike easier. Interest in the bike for him came from the Suez Canal crisis. Before that in the UK, you just rode for fun. To Moulton, like Sir Alec Issigonis, wheel size had enormous importance upon the architecture of the entire vehicle. Noteworthy that the wheel size discussion continues today.

Also suggest reading the Spaceframe Moultons for the history of the brand, industry intrigue, and how fame is fleeting.

RIP Dr. Moulton.

I traveled with a TSR2 last year. See more photos on Flickr and on G+.
