Crumpton Ultralight

so obviously the UCI doesn't have a say in how I approach a bike build, mostly that'd be because I'm not racing this thing in UCI sanctioned events.

Of course I'm rational enough to realize that removing 3 pounds from the minimum UCI weight is an exercise in playing chicken with my pocketbook that could far easier be solved , as you wrote, by taking a 3lb bowel movement. This bike is an exploration of weight reduction disconnected from any consideration of an expectation of a quantifiable performance improvement.

Still, the experience of throwing this bike side to side up a 20 degree climb is immensely enjoyable which is only in the smallest way connected to the low weight. The reality is that my goal was to build the lightest bike that still could be ridden without any concern for the durability of the components. To this end, the bike delivers in spades.

nice bike... (It was a joke mate...)

I know that there are valid reasons for the UCI weight rule, but the downside is we don't get to see how light a bike can be with the latest technology and an ample budget. Thanks for sharing your bike, and your experiences in riding it, with us!

Also the innovations you are financing (if nobody buys the lightest, most expensive stuff, it won't get made) may eventually work its way down to us mortals. Alloy components that were limited to professional grade bikes in the 1960s were commonplace in the 1980s.

Well said, sir.

The bike is incredibly solid. My previous ride (see my other bike, now in fixie trim) was a Moots Vamoots and this build can only be described as ridiculously crisp and direct, even in the contrast to the Moots.

That said, 46mm high carbon hoops do catch the wind so things can get interesting on steep windy hills. I've topped out at 60 miles per hour on one fast descent here and didn't have to change my shorts at the bottom.

Thanks for the questions.
