Caution! Sharp! Schlumpf chamfering tool


What do Swiss bike gearing systems and American solar-lit bongs have in common?

In Chico, CA, it seems to all make sense, as, after a good 16 years chamfering bottom-brackets for Schlumpf installations, our old chamfering tool just wasn't cutting the metal like it used to. After searching high and low in Sacramento (unsuccesfully) to find someone with the tooling to set a new keen edge on the cutting tool, we finally found the right guy in Chico.

Clearly, searching low was not the right approach, but Tom took a break from marketing his latest (patented) invention in order to rejuvenate the Schlumpf tool.

Thanks, Tom, and good luck marketing your invention.

The shop is open for business.

Catrike has discontinued the venerable Road recumbent trike model.

This event has taken place and the notice is simply part of our articles archive

Face-time with ICE. Ask all of your questions. Find out what happens behind the scenes. And, try trikes, trikes, trikes... including the fully automatic ICE Adventure electric trikes.

An inexpensive hitch-mount rack for folded recumbent trikes. For example, the ICE Full Fat big-tired adventure tricycle.

Azub trikes are adventure ready

Azub will be at AlphaBENT on Wednesday, October 23 to show the latest Czech recumbent technology. Come to for test-rides, and bent-talk.

Catrike has made wider hubs with through-axles standard equipment on all large-wheel models. This change affects the following recumbent trike models: Expedition, 559, Dumont, and 700. The change promotes laterally stronger wheels and prevents movement within the dropouts under load at the expense of compatibility with equipment such as electric hub moters that are designed to the older 135mm dropout widths.

Find out about options to standard drive systems: planetary gears, continuously variable transmission (CVT's), Capreo cassettes, Schlumpf drives, Rohloff Speedhub, and Patterson Metropolis 2-speed bottom-bracket / spider.

When are the different options appropriate? When are they on the edge? What works with what? How do you install?

We'll cover the highlights. There will be Show and Tell. Focus this week will be on the Patterson Drive. We'll put one on a test boom for a trike and see what it takes to do it.
