Re: Dynamo AA battery charger - do they exist?

A cylindrical shape is not very good from a packing things into a small space point of view. It depends what batteries you get. Panasonic Eneloop Pro are really good at 2500mAh Or you can get these at 2700mAh https://www.amazon.co.uk/Maha-Energy-2700mAh-Capacity-Rechargeable-Battery/dp/B00A9KTPY8/r...

Re: GPS computer vs dedicated phone?

I am going to get something like the Garmin 64ST. It is fully waterproof and great on battery life. It also takes AA batteries, which you can get anywhere. Plus you can load all your own custom routes using something like basecamp. I ruled out using a phone for the following reasons: 1) poor battery...

Re: Dynamo AA battery charger - do they exist?

You could always try a simple DIY solution. 4 diodes arranged in bridge and fitted inside a poly tube. Boxes that take AA batteries are also cheap. Total cost pence. No need for a smoothing capacitor as pulse charging is regarded as being fine for this application. Dynamos are rated at 3 watts, so ...

Re: Dynamo AA battery charger - do they exist?

Best way to do, is to carry a small powerbank: charge that when riding (and if it goes damaged, can be replaced without loss of data) then recharge your devices overnight. But if your only requirement is to charge AA batteries that does not make sense. It is not logical to charge a power bank to th...

Re: Dynamo AA battery charger - do they exist?

Probably because AA rechargeables are going the way of the dodo. Lithium batteries are taking over the rechargeable field and for bicycle equipment the USB charger can be easily set up for a dynamo. I don't know if I agree with that. You can practically buy AA batteries anywhere in the world. Good ...

Re: Dynamo AA battery charger - do they exist?

I googled 'USB battery charger' and dozens of products came up. Same for Amazon I don't want a USB battery charger. All I want is a AA battery charger with a built in voltage regulator that I can hook up directly to a dynamo, in a sealed unit. I can't understand why all the cycling gear seems to be...

Dynamo AA battery charger - do they exist?

I am looking for a solution to charge AA batteries from a dynamo. There are plenty of solutions for USB batteries / charging phones on the go etc, but I can't find a dedicated product just for AA batteries. I only require the ability to charge AA batteries. One option is a voltage regulator and then...

Re: Hydraulic Shifting for Rohloff etc?

I found this today which shows installation / workings of the hydraulic shifter:

I have to say the price does look steep for what it is.

Hydraulic Shifting for Rohloff etc?

I remember reading this magazine article some time ago about hydraulic shifting for the Rohloff: https://www.cyclingabout.com/2017-bpod-pshr-trigger-brings-hydraulic-shifting-to-rohloff-hub/ The product is called the Bpod PSH’R and is available here for € 646.00: http://www.pshr.ch/shop.html Just wo...

Re: What frame with sliding dropouts for Rohloff?

So what do people think of these types of sliders. I like the screw design at the back, as it looks like it would reduce slipping. I heard you can get specific Rohloff sliders. I would be interested to hear what people think is a good option for this configuration? https://preview.ibb.co/j3E07b/clos...

Re: What frame with sliding dropouts for Rohloff?

I woulld have thought that a frame with track ends should work (but it probably won't take disc brakes) . There are lots about of various ages and prices. Pedalpower2 I think this terminology gets confused, do you regard these as track ends: 1) https://image.ibb.co/kVmGCb/3614720301_a047fc1101.jpg ...

Re: What frame with sliding dropouts for Rohloff?

It's a very solid bike - I call it the battleship - and it carries a camping load well, which was my original requirement. But it is no fun at all to ride unladen, very stiff and not comfortable, even with big tyres. Be careful what you wish for! Thanks for that info. £250 does seem very cheap, won...

I think all the suggestions are useful, and I am seriously considering a longitude. But for actual "sliding dropouts" I don't see anything that suits my spec? Is anyone aware of anything?
