Nexus 7 speed hub

[Iain G]

Hi I was hoping someone could help put me direction regarding the possible bolts/nut sizes on a nexus 7 speed hub casing to sprocket.please? These bolts snap easy with the sheer weight of my tricycle so I need to get a bumper pack of the correct nut & bolt for this hub to sprocket while I find out what's needed to modify or replace the existing problematic hub. Any advice given is appreciated.
Thanks
Iain

Thanks mjr unfortunately my hub has been modified to have a 26t SS sprocket that was put on by the company who helped me get my adapted tricycle over from Germany. The trouble is I've not been able get the info I need from them as of yet. I'm itching to get back on the road as my physical health has been suffering of late. I need to find a suitable 26t single speed sprocket & a bike repair shop that will drill/bore the holes required to secure the sprocket to the hub. I can't do the job myself as I have paralysed both my hands (typing with feet). My tricycle is body steering if anyone's wondering how I ride it. If anyone has recommendations that would be great I live in Leigh, Greater Manchester btw.
Cheers
Iain

@mickle is the go to man around here for adaptations of that sort I reckon.

 

[Iain G]

How did I forget to ask the great @mickle thanks Tim .

 

[mickle]

Call me 01904636812 during office hours. I'm sure we can help. It's a Draisin is it? Judging by the frame.

Nice one Mickle & yes it is a Draisin 'Relaxino' tricycle built late 2012 good observation you know your stuff!
I'll call you in the morning thank you.

Nice to talk to you Iain. I'll drop you an email when your hub arrives in the workshop and we have a verdict. Cheers, Mick

 

[Iain G]

Cheers hopefully my other gear components that have been fitted are of a compatible ratio ( both chains single speed) 48T crank that drives a 24T sprocket attached on the outside of hub along with a 26T sprocket on hub going to 22T sprocket on axle * this tricycle has 2 chains*. That sounds confusing sorry hopefully it'll easier to going over things on the phone. I'll ring you Wednesday morning if you're free for a chat.
Thanks you
Iain

 

[mickle]

You've got email from our Chris about your hub.

 

[Iain G]

Thanks mate I'll be seeing you with the Draisin next Tuesday. I look forward to meeting you & Chris & finally getting my tricycle set up properly.
Cheers Iain

@Iain G do you use a twist grip shifter, or would you like to? I'm sure I have one lying around in the garage that you are welcome to if it's of any use

 

[Iain G]

Thanks Soltydog that's a very generous offer I currently use a 7 speed gear lever operated by my foot hen riding. What gear shift I could I use with my unorthodox technique is unknown although I may have a better idea once me & mickle have gone over some set ups on Tuesday. My hub has been set up poorly with inadequate modifications so my cycling time has been hindered a lot. I may be getting a Alfine 11 fitted if everything works out right then hopefully I can start getting some good miles on my German trike tanker lol
Cheers for the offer Soltydog I'll bare that in mind if I do decide take a different route to the Alfine 11 hub set up thanks. I'm hoping I can have the Alfine as I desperately need the gears that's for sure
