Bandit finished
For those of you who may not have been following my earlier posts on this topic, the pictures below represent a single hand control system on a Trek Domane nick-named the Bandit, a project that Trek started for me, a one-handed rider, some years ago.
Some great bikes resulted, but one of the project goals was to make the adaptation with easy to assemble, completely off the shelf parts. Last week, it happened. The bike uses Shimano Di2 components set up in synchronized mode, so both the shifter on the hood and the climbing button on the bar top engage the full range of gears. Likewise, both the brake lever on the hood and the Shimano GRX bar top, in line lever fire the front and rear disc brakes simultaneously with great modulation and very little lever pull effort. The result: full one-handed control of every braking and shifting component from the bar top/the hood/the drop. The device attached to the outlet portal on the GRX lever is a Pro Edition Double, made by a Korean company named Outbraker.
Long story short - this is awesome! I have never felt safer or more in control on a bike.
Please forgive the duplicate posting on several forums - you just never know where you might reach someone who has a friend who might benefit from something like this.

Why even have the left lever? I was dropped by an amputee rider who had some kind of device between his shoulder and the bar. I think it was to help him with control and he would take his hand off the bar to wave. He was a very strong climber and I saw him way up in the mountains.
Did you end up doing any more gravel/off road riding? I remember you were trying it out a while back.

1. Left lever is there for symmetry - looks - and when I loan the bike to my son.
2. There are some pretty cool prosthetics like what you described but they are of limited use to me given where my amputation is - at the shoulder..
3. Since long mountain climbs are largely in the saddle, an amputee is not at a great disadvantage. I have been doing the Triple Bypass and other mtn. climbing events for years.
4. Only about 500 miles of gravel last year. Hopefully, much more to come this year.

Beautiful bike. Love what’s been done to it. I hope you get a lot of safe miles on it!
An off topic question. I have to really work on my bike posture. For whatever reason I tend to lean to the left when I ride. When I’m leaning, if I look straight down when sitting on the saddle and pedaling, the top tube is way right of the bottom bracket. It happens when I haven’t been riding often and especially occurs on really long rides. My left arm will get very, very tired. To correct it I make myself lean to the right until the bike frame under me is properly aligned. Maybe for me it’s just poor core muscles.
As hard as it is for me I was wondering if that’s something you deal with. I can’t imagine riding with just one arm. Mine would probably get extremely tired after a while. Do you do any additional efforts to work on your core?

I don't do any core specific work, although much of my time on the trainer (about 7 hours a week these days) I'm down in the drop or puppy paw off the front. Other than that, 47 years without an arm now and a really active lifestyle has pretty much done the trick. On super long rides - over 100 miles - I find myself sitting up a bit with my hand on the bar top, which is probably somewhat fatigue related. Makes me very excited about the bar top lever.

This is a brilliant piece of adaptive engineering -- thanks for sharing. I have a neighbor who lost his left arm at the shoulder in a freak accident at a construction site -- I'll mention it to him next time I see him out and about in the 'hood. I have another friend who is physically active and who years ago lost his right arm a few inches below the shoulder. What would be involved in adapting for left-only operation, which also might appeal to the bike polo set?

As for left side - right side, obviously the di2 brake shifter comes in both left hand and right hand versions, and the left lever can be programed to do exactly what the right does on my bike. The GRX bar top lever also comes in a left side version. The Outbraker has no idea what side it is on, so I think the lefties are set.

Wow, just plain WOW, this Bandit is one beautiful piece of engineering and adaptive design/craftsmanship. Good see you got it finished before the spring is upon us!! That green colourway is magnificent, great execution by the Project One shop at Trek. You have had some great collaborations with those wizards of bicycle advancement.
