Lightspin's another one to bear in mind depending on budget. So easy to spin it never slips, even in
the mud. Regulated so you don't blow bulbs.

I have thought about this but the bike in question has a front disk brake. I have a Nexus hub dynamo
on one of my other bikes, and I can see that it would be incompatible with the disk. Is there a make
of hub dynamo that can take a disk?

The other drawback is fitting it and cost - given also that I'd probably need to get a Standlicht
with Lumosensor too.

But it's very heavy, expensive and I don't think it fits a standard braze-on :-(

The only problem I have with Nordlicht is that it does slip in the rain. I've just ordered a new
metal wheel for it, which I'm told works better. My LBS who sold me the original was completely
useless when it came to getting even a spare rubber wheel, and couldn't be arsed to find one for me.
5 minutes search on the web, and I found a shop in Oxford who say that they have hundreds in stock
and will post to me. Shop is at btinternet.comDefault.htmOpen ↗

John was able to give advice on ones which never slip in the rain, so he may be worth chatting to.

This is a similar problem to the one I have: my general-purpose bike has a front roller brake, and
although such things as roller-brake/hub-dynamos do exist, my fairly competent LBS say that Shimano
don't export their full range to Great Britain.

I've been recommended the top-of-the-range B&M bottle dynamo. Apparently it is very quiet and
efficient and less inclined to slip than cheaper versions.

I hope you have standlights anyway? ;-) You can get a separate switch that replicates the
"Lumosensor" function: ON/OFF/Auto. I think Shimano make one and I have seen it in the UK so they
probably do export them.

This might do you. About twice as much as the regular nexus hub [which is only 36 euros compared to
50 quid here...joke] but still not that bad a price and I don't think shipping is outrageous.

According to the latest Velovision mag Shimano have a new version of the Nexus for disk brakes. I
don't know if it is on the market yet.

I'm pondering swopping my Sachs drum brake for a Nexus hub dynamo+roller brake. Though my experience
indicates they aren't as nice as the Sachs drum brakes.

TBH, while nice bits of kit, unless you do long rides IMO the extra cost of the top of the range
bottle dynamos isn't worth it for a small reduction in drag (I've never had any problem with
slipping and my AXA HR.,

I don't bother with built in standlights. I use a LED light (the Cataeye EL200 at the mo' I think)
as well as my standlight/backup light

Yes, Shimano now do one. There's a photo and short item in the latest Velovision. I've just had a
Shimano dynohub wheel built for my SO's roadbike, it's very good and came with a light sensitive
auto switch.

Doesn't the SON come in a disk form? (In fact, doesn't Guy have one of these?)

I got the shimano switch from Settle cycles very easily - 12 quid or so?

Nexus roller brakes are weak, in my experience (with rear Nexus 7). I could not lock the wheel
deliberately - which I think is a fair test for the power of a rear brake. No way would I use one on
the front.

Sheldon Brown recenty posted the following on rec.bicycles.tech - thread: 'Nexus Roller Brake -
Improved by now ?'

"The front brake hub incorporates a "power modulator" which limits the maximum braking torque. The
purpose is to prevent clueless clutzes from doing endoes and suing Shimano. The unintended
consequence is that maximal front braking is reduced, which might make the difference between
stopping in time or not.

"At the Interbike Outdoor Demo last month I test rode a Bianchi with the new Nexus 8-speed internal
hub (which I liked very much.) This bike had a Roller Brake in back, with a V-brake in front.

"The paved demo course featured a long, straight steep descent with a right angle corner at the
bottom. I too was curious about the performance of the Roller Brake (I left it off of my own Nexus
bike) so I decided to give it a good workout. I got going quite fast down the hill, then tried to
slow for the corner using just the Roller Brake. At first it grabbed nice and hard, but as the brake
heated up it faded markedly, and I had to use the V-Brake to avoid a crash.

"As I said, this was an extreme test, I weighed about 230 pounds at the time, and I got going at
quite a clip down the long straight hill.

"The Roller Brakes are probably OK for light duty use in flat terrain, but I wouldn't recommend them
for cyclists who ever go fast, or ride in hilly terrain.

"It's OK for a rear brake, if you don't mind the weight, but I continue to be highly dubious about
using it as a front brake on bikes with full-sized wheels."

The Roseversand website shows two (I haven't yet found out what the difference is). The prices are
Euros. (and the standard NX30 is only 36 Euro !)

My recumbent has a disc-brake SON on the front. Wheel build was about £20, the dynamo of course was
Lots More but works 100% perfectly in all conditions and requires noticeably less effort to push
along than even the Nexus when powering. There is a disk-brake Nexus now as well, according to
Velovision, which would also be a strong contender (excellent value for money and the natural choice
if budget is an issue).

You can get the SON from bicycles.de or Marten at m-gineering for less than you can buy it in the
UK. Importers are St John Street.

Lights with standlights are not too big a problem to get, alternatively you can fit a small blue-
white LED which in my view is perfectly adequate. Neither meets the Road Vehicle Lighitng Regs when
the dynamo is not running, so in both cases you are theoretically obliged to move to the left of the
road when stationary (the law is an ass in this case).

My B&M6 is okay so far, but is only about a month old... It works better than I'd expected though,
and my impression is that B&M can be trusted on bottle dynamos.

But I much prefer the dynohubs. I have SONs on the Brompton and 'bent, and the only reason I have a
bottle on the 8 Freight is you can't put a SON on a monoblade fork with a drum brake...
