I'm adjusting to life with a pretty damaged left hand, I got out on the MTB at the weekend and managed OK but essentially I can either hold on or brake,  which isn't ideal. Doing both again would be nice. I'm after any recommendations on somewhere to go and go through what I need and get the various bikes customised so I can ride confidently and safely. Based in Derbyshire but happy to travel. 

The issues are

Missing end of thumb - missing index finger to first joint, other fingers have virtually no independent movement, cannot fully extend or contract. Significant loss of grip strength and reduced sensation. I also get intense hotaches if it gets anything like cold.

I don't think huge amounts need to be done and I've done a bit of looking around but feel that an in person consultation with an adaption specialist with a good range of options would be ideal.

Hope do a dual control lever that will let you control both brakes with one hand.

Apologies if you already have these.

Cycling UK - don't just look at the forums they may have some other resources.

One of the ladies in my local cycling club has some disability issues and has a dual control brake lever on her road bike - I'll ask her what the set-up is.

Building up the grip for your left hand to much larger than normal diameter might make it easier to hold.

Slight aside, but a mate of mine with a wrist injury uses tri bars on his road bike to take the load off.

There's an article here about a rider who has no use of one hand

He seems to have worked with Mojo (suspension people) to develop some adaptive parts.

I imagine someone well skilled in the use of a 3D printer would be able to get you going somewhere.

Not really answering your question, but giving you somewhere else to look... What does Dame Sarah Storey use? Might be worth asking her - she's active on Twitter and seems like the type of person who would respond helpfully to that sort of question.

I'm only half joking when I mention back-pedal brakes, depending on age you might remember them? Think the Americans call them coaster brakes

Surely there is a variation of these for suitable to mount for a mountain bike?  That'd mean you'd have an ordinary lever for front (use right hand) and backpedal for rear brake

Maybe contact British Cycling. 

Thanks all, some great ideas to follow up.  Much appreciated.

Good luck with your search. I can imagine it's been quite a challenge to adapt but, it's not the dark ages any more and with all the technology around hopefully you'll be back out on the bike a good as ever.

Short term fix maybe but how about swapping the brake levers to allow your “ better” hand to do the back brake which tends to be the one most used ?
 

Good Luck !
