Dynamo Lights

I reckoned that if people were struggling to get them to stick to shiny flat paintjobs then there wasn’t going to be much hope for me.

Ah. I wonder how many of these people were putting them on bikes without mudguards and/or bikes that had been cleaned with bike-shine etc. both those things can make a difference. Also, as @Brommers said, get the frame nice and clean with rubbing alcohol and warm the strips a bit beforehand and you should be golden.

From what I remember the coaxial cable is a smidge too thick for the channel in a Di2 strip.

Can't speak to your experience, but that hasn't been mine.

Not sure if this is a repost but I think I’ve found a (relatively) good value alternative to the SON crimp tool:

I’ve ordered one so will report back :]

^ that's the style I have. It's really satisfying to use.

I finally got enough bits together to complete wheels to drive dynamo to drive lights and put it all on one bike. Pretty happy with the rear light routing: drilled an angled hole at top and back of fender and glued to the inside of the lip.

Pretty tidy, but might it be worth zip-tying the cable to the rack for extra tidiness?

Thanks - yes probably, especially if it rattles. Might add some more glue to the outside of the cable exit too. Waiting for snow to melt here for test ride.

I use the SON one most days I’m at work, and it’s fucking good. The stripping tool is also great, but less so for thin BM wiring.

Tool above for anyone doing wiring now and again is plenty good enough, used and seen far worse!

...and it’s fucking good.

Totally agree. It is a pleasure using the right tool for the job and not using a set of pliers.

If looking beyond Knipex, there are some equivalent tools for a lot less that will give a good crimp.

Absolutely, you can buy a usable ratcheting crimp tool for even less, about 8 quid on eBay.

They make a lovely job on brake and gear cable end caps too.

Does anyone have a B+M IQ-X fork mount spare?
Also, less likely I suspect, but if anyone wants to swap my rear Secula light with seatpost/seatstay mount for a mudguard one, would also be interested.

Im pretty sure SJS sell them if no one does have a spare one, I also think the old style 'bent wire' one fits those lights too

Yes, seems to not be hard to get hold of them, just assume a lot of people get them and then switch to different mounts. I'll have a spare supernova one once I do this.
The bent wire ones are a bit ugly.

I have one in black going spare. I had to use the bent wire on on my Cargo bike as the cover kept catching on the bulky IQ-X one.

Send me a PM and we can discuss.

Got all my parts in. Jtek hub is dinkier than I imagined it was going to be from the photos. Connector of a bit of a pita, had to tin the wire with my soldering iron to get them to hold together enough to be inserted back into it.

IQ-XS headlight seems really nicely made. Only had plastic bodied ones before so this is a nice treat.

Son coax cable fits though the di2 guides fine, standard bell wire is maybe a slightly easier fit though and even with the coax in hand it’s no more obvious how I go about sorting one wire from the other if I need to shorten so I may just use the bell wire if it’ll be mostly hidden in the di2 guides anyway.

Is the clear sheathing already in place on the core and the black that I’ve got the arrow pointing to, is that wrapped around the clear then gathered together and shrink wrapped and the a bigger shrink over both?

The clear sheathing is in place already. As you say, once you remove the outer black sheathing you can group the strands of wire and then cover in shrink wrap then a larger piece over the area where they split.

oops wrong thread

I decided to just use the standard bell wire. So much of it is hidden inside the di2 guides that I reckoned the Son coax was more hassle than it’s worth.

I also made a little pigtail to take up the movement of steering and reckoned the bell wire would actually work better than the coax for that. Managed to do it all with only one zip tie too!

Cleaned the underside of the dt with ipa wipes then warned it carefully with a butane torch and stuck the guides up inside my clothing to warn them up. They seemed to stick pretty well but dunno how they’ll last as the temperature in the garage drops overnight.

What's the rear light mount, looks neat!!

Made it myself. It’s mudguard stay.

So good. Have you got a full pic of the bike?

Not in its current build but before I changed to flat bars and a rim brake and fitted the dynamo stuff...

has anyone used something like this? I need to clear a small handlebar bag and this might be the neatest solution. (i'm not paying £35 for this though)

alternatively can you buy an extra long standard brake hole mount ? needs to be like 4cm longer

Seems to be the longest available, It should be 3cm longer so will see if that's enough!
