cheers


Already got some. But is it really a decent alternative?

Re: Rumbling Rohloff

... Heh. Maybe they did havent looked. The sprocket is just butt up to a rubber seal it just doesnt seem right. What happens if the sprocket facing gets scratched. Those sprockets are made of pretty good steel that is heat-treated after, I cannot see them been easily "scratched", likely y...

Re: Rumbling Rohloff

I'm struggling to think of an IGH where the sprocket mounting doesn't also include part of the sealing/dust shield retention. If it is a bad design it seems a very common one. Also, don't Rohloff recommend that you don't lay the hub down on its side anyway? BTW did the changes sort out the transmis...

Re: Rumbling Rohloff

Just an aside form the original post. I took the sprocket off and also changed the oil. Without knowing I laid the wheel sprocket side down (without the sprocket replaced) and all the oil drained out much to my extreme anger :twisted: I replaced the sprocket and the oil stopped leaking. So it looks ...

Re: Rumbling Rohloff

If it's the chain, chainring or sprocket how is it making that noise. How is the best way to find out if it is one or more of those. There's no chain tensioner on my setup. So yes some adjustment would have been made to the chain tension but I'm careful not to have it too tight or too slack. Gears ...

Re: Rumbling Rohloff

I guess it's trial and error. I'd start with the easy bits, slacken off your skewer slightly and ride up a hill. If no luck then it is likely to be some part of the drive chain. Check the chain carefully for any obvious flaws, clean and refit. If problem persists Check the sprocket for asymmetry on...

Rumbling Rohloff

Two days into my last tour my Rohloff started making rumbling noises in gears 1 - 6. The lower the gear and harder the pedaling the louder the rumbles. All Rohloffs make a rasping noise in gears 1 - 7 which is normal but I havnt heard this noise before. So do any other Rohloff owners have the same p...

Re: What do people use for GPS backup on tours

This thread is refreshing. This forum has a tendency towards the traditional, since if people have been touring successfully with the CTC for a hundred years then any newfangled tech that isn't steel frame, downtube shifters and rim brakes must be viewed with suspicion. And yet in this thread the c...

Re: What do people use for GPS backup on tours

I'm a Search and Rescue volunteer, so don't use anything other than OS explorer. The batteries never run out, it doesn't need a view of the sky, it works in conditions that might make a satellite lock difficult, and it costs a fraction of the price. In SAR we spend a lot of time retrieving people w...

Re: What do people use for GPS backup on tours

In 'the middle of nowhere' the choices are few and far between, so a GPS is not so essential.. a good paper map with some basic knowledge of where you were, how far you have travelled and in what direction should see you good. A backup for the GPS .. a smart phone with an app - OSMand, mapout, maps...

Re: What do people use for GPS backup on tours

I can't believe that this is even being discussed! Next it'll be spare stoves, wheels, why not take a spare tent - just in case? Get a grip folks, learn to properly read a map, have a route list (towns you want to pass through) and get on with the riding! It's getting on with the riding I want to d...

Re: What do people use for GPS backup on tours

Depends what you're trying to achieve. If your pleasure is just in the touring a GPS gives turn by turn information so you dont have to think about navigating. But if you enjoy navigating as much as touring then your way is best. Personally the only thing I have against GPS's is when touring in gro...
