Cycling in Melbourne Australia
I'm doing a bit of upgrading at the moment and I seek advice. I'm putting a Shimano roller brake on the back and wish to put a Sturmey Archer drum/dynamo combination up front in the near future. Each brand sells levers specific to the task but I'd rather have two of the same style levers on my bars. Do the sturmey archer levers work with the shimano roller brake, and vice-versa?
I'd try it out, if it works - good.
If not, try plan B, or C...
If you have pictures of each lever you should be able to tell if they're roughly compatible.
The main thing is how much cable movement there is for the lever movement.
This depends mostly on the distance from the pivot point of the lever to where the cable attaches to the lever.
Yeh there's other stuff like how long the lever is and how far away from the bar it is in resting state...
This is why I say if it works, good.
Put some pics up :)
They should work - check that they are both non-linear pull brakes, that is, they get their mechanical advantage from their levers, like a road brake, as opposed to a V-brake which gets its from the length of the arms at the brake(and so the cable has to move further). I'm pretty sure that roller brakes are, and a brief google tells me that the Sturmey Archer is too. Give it a try, talk to your LBS. My question is why bother with roller cam brakes? there are plenty of alternatives. Is this the cargo bike?
Thanks for the responses. I ran into a knowledgeable soul yesterday who informed that the answer was yes, it does not matter which set I get.
As to the why, well I'm putting a nuvinci on the back and a dynamo up the front. I can get Sturmey Archer dynamo and 90mm drum combination for quite a steal and the comments I've found for it have been positive. The nuvinci has a spline to attach the roller brake. I've been unhappy with my rim brakes and would also like to simplify my bike and from all accounts this isn't a bad way to go out about.
VERY interested to hear how you go with the dynohub/brake. I've thought about that for some time... as my commuter has a SRAM 3 spd hub/coaster, so the combo has attracted me.
I know that shimano has recently made its dynos a LOT more effective. I wonder if SA have too?
Yeh, I'm keen to see how the dyno hub goes. If they have improved I might check them out again.
Lights have improved too so might be time to experiment.
Hmmm, wonder if I can get a dyno hub with disc mounts..
Shimano make dynamos with disc mounts. If my bike was set up for them I'd be heading in that direction. I've also just spotted another interesting product. The FSA Metropolis Patterson Crankset. It is a bottom bracket with a two speed internal gear set up. At 1:1 it is a 28 tooth chainring and the second setting is about 1.6 so it equivalent a 42 tooth ring up front. From all accounts it is good. The nuvinci I've got only has a range of 350% so the Patterson looks good for expanding the gearing.
