I built a special commuter bike using Shimano CUES and Sig.rando.

I've been vaguely thinking about it for a while now: my dream commuter bike plan, built with Sig.rando.

Shimano offered to provide me with their new CUES series groupset, released last year, and so the plan got underway and has now come to fruition.

It's finally taken shape, so I'd like to introduce it. Thank you, Shimano!

The general theme is a blend of old MTB and old motorcycle styles.

I prioritized atmosphere and usability over performance like lightness or speed. I avoided overly extravagant parts, and if I found a good used one, even better – that's how I put together the components.

The frame I used is the Sig.rando in size S.

For the color, I paid homage to the late 1980s GT Karakoram, which I wanted when I first started riding MTBs, with a Grumpy Paint splash paint job. I even did the splash parts myself. You can see the painting process on YouTube.

I think it turned out quite well, if I do say so myself.

Now, about the CUES. I was provided with the U4000 series, which is the most basic 1x9 speed model.

The complete groupset, including hydraulic brakes, costs just under 40,000 yen (tax included). Without the brakes, it's less than 30,000 yen.

I've been using it for my commute for the past few days, and despite the low price, the drivetrain and brakes perform reliably. While the feel and quality are naturally not on par with high-end models, for short commutes and everyday use, I haven't encountered any inconvenience or problems. The lack of a cheap feel also makes a very good impression.

Furthermore, the CUES chain and cassette sprocket use the new LINKGLIDE standard, originally developed for e-bikes where durability is paramount, so I have high expectations for its longevity. I'll continue to test it with daily use.

It's a component that makes you want to put any spare frames to good use.

I plan to customize it further with dynamo lights, a rack, and other features to improve usability. I'll share updates as I go.

I usually ride it to the shop, so feel free to test ride it there.

Just ask Shimizu.
