How loud is a coasting Rohloff?
« on: July 19, 2012, 08:29:29 AM »
Hi All!

This may be an unquantifiable question, but how loud is a Rohloff hub when freewheeling/coasting?

Is it about as quiet as a Shimano freehub, or more intrusive like the "can of bees" sound made by a Chris King freehub?

Is it very close to silent?

It doesn't really matter, I suppose, but I'm curious. My guess is, the oil-filled hub will damp any ratcheting...if the hub does indeed ratchet?

Best,

Dan.

Dan,
It is variable depending on the gear it is in.
I have to say I don't really notice it now.

Of course if you are freewheeling you can just select the quietest gear - it is so easy to change gear ;D

More noisy than a Shimano freehub. Not as noisy as a Hugi. It has the reassuring clicking of a quality timepiece  :)

When riding along (pedalling), gear 8-14 are virtually silent, quieter than a freehub drivetrain as there are no jockey wheels. Gear 1-7 are the noisier pedal drive that people often comment on, but once you realise that they are still very efficient and there is no added drag involved it's all OK. After the first oil-change they do get a lot quieter, and better still after subsequent changes.

Julian.

As Julk said it's depending to which gear your in! But it also depending on km's (mile's) your hub has done?

Mine freewheels silently in the lower gears 1-7, and has a variable amount of ratchety sound in gears 8-14, but not anything you notice much after the first few rides.

Never thought about it.  It must not be noticable enough to come to my attention.

A coasting, run-in Rohloff is pretty near silent. A slight whirring of gears, not unpleasant.

Under stress, the sound differs according to which gear you're in. The ticking of spokes is louder than the high range of a run-in Rohloff gearbox. However, gears 7 and 8 make a sighing sound I found enervating when my Rohloff was new. It takes a fair way to run in, roundabout 2000 miles. Generally, I would say even a run-in Rohloff is louder than a good Shimano Premium Nexus 8 speed box (which for practical purposes is silent, a standard to aspire to), but much quieter than a derailleur transmission; there was less noise with a Rohloff than I expected from descriptions because you're dealing, in the main, on these fora with cyclists who're obsessed with their bikes and actually listen to them. Since I tend to converse with people when riding, I no longer notice the very little noise the Rohloff makes under any normal condition of operation; it is not intrusive.

Actually, the loudest hub on any of my bikes now (they're all IGHs), is the electric motor on my Kranich. I think that puts all the comments in this thread, including mine, into perspective.

It is worth answering the subtext of your question: Is the Rohloff a refined gearbox? And the answer is, if you wish to speak relatively: No, all my Nexus boxes are much smoother and more silent, and the only NuVinci box I've been near also appeared more refined. However, a Rohloff is so much more refined than derailleurs, that the answer must be, in absolute bicycle terms, the Rohloff is more than adequately refined. We can also ask a question to get at the proof of this pudding: Money on the table, will I exchange my Rohloff box for say an Alfine 11-speed or a NuVinci CVT, and pocket several hundred smackers? Answer: No, I won't. The Rohloff is just right. And it makes up for its modest shortfall in refinement by its great gearing range (why I bought mine), by lasting practically indefinitely and being ultra-low maintenance into the bargain, considerable advantages worth more to me than a few hundred spondulicks of whatever denomination.

Wonderful responses! Thanks everyone!

This is much better than I would have imagined. I was prepared for a Chris King "can of bees" sound, with a loud, continuous buzzing no matter what while coasting (worst-case scenario), so this is a happy surprise.

One of the things I enjoy doing is coasting nearly silently down fire roads, forest trails, and single-track, and surprising wild animals because of my quiet approach. Some of my bikes are rigged for silent running. I have an old Bicycle Research/Phil Wood freewheel-packer that I use to pump Phil grease into the freewheels of my bikes that use them. Even in cold weather, I've never had a problem with lockup in over 70,000 miles of combined use, and the things are deadly silent. There are ways to do similarly with Shimano freehubs, but I have never done so. On those, a generous packing of the hubs with grease allows enough to migrate to the freehub ratchets to quieten them considerbly.

If the Rohloff is only as loud as what you have all described and gets even quieter with age, then all sounds promising. Maybe not for silent running, but also for not sounding like one of those twirly party noisemakers, either.  Going downhill at speeds close to 50mph/80kph has its own element of surprise, and I need to be careful lest I collect the whole set of wildlife. That's how I saw Mr. Bear on my last ride down Mt. June.

I'm kind of intrigued by the possibility of hearing the little Rohloff elves working away in their spinning home, doing what they need to move me ahead. "Like a clock" sounds very promising, indeed!

This...this is exciting.

Though I didn't have Andre's subtext in mind when I asked the question, I'm glad he mentioned it. Andre, your comments taken in view of the sounds described make sense. What I want/need is a sound (sorry), reliable drive mechanism that will work in harsh conditions. So far (with the few brief exceptions related to really old Sturmey-Archer 3-speeds and one I converted to a 2-speed Fixed-gear through a driver modification long-many years ago -- no such plans for the Rohloff!), I only have experience with derailleurs.

It is only reasonable there would be a break-in period as the gears learn to mesh in greater harmony with one another, and I am open to and welcome new opportunities to learn and grow, myself. I've started on a learning curve, and for a Growth Addict like me, that is exciting as well. I'm actually looking forward to adapting and learning new techniques and embracing a new experience. Lots to Learn, which is akin to sitting me hungry at a giant buffet and saying "Dig in, Danneaux"!

I've set myself the task of re-reading all posts under this board. It is amazing how a change in circumstance makes all posts appear fresh and new when they have a personal context. Thanks to all who came before, and for so kindly answering my questions as a newbie Rohloffer. This is nice; everything old is new again!

Best,

Dan.

i can just imagine you riding along a quiet  mountain track and some poor old bear sitting up a tree wondering what the hell is that noise coming from dan's hub, [Oh!] i bet he forgot to grease it up  ;D ;D

Jags, I did a tiny Mod edit of your language there to meet Family standards, but I have to tell you...

I was drinking a glass of orange juice as I read your post, and now I have to clean my computer screen.

Hahahaha!  ;D

Made my day!  :D Thanks!

All the best,

Dan. (who is still chuckling...)

Hi Dan and Everyone!  I'm sorry I've not introduced myself yet, my name is Holly, and I'm a nice old-lady living in Florida.  ;)

I bought my Raven Tour last year, and have about 2000 miles on the bike.  My husband, the aircraft mechanic, has 2 Rohloff bikes, one a really beautiful Trek 720 he recently built up.

One thing I learned quickly, is "all Rohloffs are different".  The Rohloff Thorn sent me, was one of the 'bad' ones Thorn describes in their "Living with a Rohloff" brochure.  In fact, it was worse than that, I think the only gears that shifted cleanly without jamming were 7-8.  Thorn forwarded my issue to Rohloff, and washed their hands of me, and I needed to pay to have the gear corrected.  Because Rohloff considers that performance to be OK.  Fortunately, Cycle Monkey here in the US was wonderful to work with, and I now have a Rohloff that shifts much as you folks on the forum have described.  A whole 'nuther (long, sad) story.

Anyway, I heard over and over from Rohloff that 'all Rohloffs are different'.  Mine, good geared or not, has always been quiet to pedal.  I sneak up on everyone on the rail-trails.  My husband's Bike Friday Rohloff is noisyish pedaling, but shifts decently.  His Trek Rohloff is as quiet as mine, but I haven't ridden the bike (too big for me), so I can't tell how it shifts but watching him ride it, seems to be OK.

But to answer your question, I think all 3 bikes go TICK-TICK-TICK-TICK-TICK etc. when they coast.  It was so loud, at first I thought something was wrong, but now I'm used to it.

So Dan, from my experience, I don't think you are going to know what kind of Rohloff you are going to get until you get it.  And then you get what you get. 

Dan, I'm so happy you are getting a replacement bike.  I saw your vdeos and they were frightening to me.  One of my old bikes did that when I tried to use it for touring (what did I know)!

Thanks for sharing your tales of travel and trials.  I look forward to the next episode!

Hello, Holly!

A warm "Welcome Aboard" and I look forward to hearing more from you.

I'm so sorry to hear your Rohloff had problems; I know how frustrating it can be when you're the one who happens to get something with a problem. It has happened to me with a number of top-rated consumer products, and more often than not with laptop computers, it seems (4-6 motherboard replacements for each of four individual examples from the same manufacturer indicates a Problem).

In my other life, I'm an educational consultant in private practice. During the winter months, I do policy analysis, create customized contract training modules and consult on research design and methodologies and made some advancements to the field. In-between and in better weather, I put those same skills to use under contract to a number of outdoors companies as a product field tester and catalog-product photographer. In the latter role, I get to see firsthand a lot of pre-production merchandise (it "looks good" but is not complete and sometimes it is not even non-functional, but I haul it into the back-of-beyond anyway to take pretty pictures of it for the catalog -- this is why the production pieces sometimes look waaaay different than the catalog or website photos). I also get to field-test some stuff that is good and complete and not-so-good and complete and what-were-they-thinking?!? I rarely get to keep these things, but it helps to handle them in their intended environment. There's a lot of stuff I wouldn't want to buy, and some I really lust after but have to save up for, like everyone else. Most of my own stuff is older and proven and I have come to trust it because it has a good track record for me in my own kind of use.

As a result of all this, I'm really interested in how things work out for the end-consumer, and stories of bad are as useful as good. They're all data that can be used to make a decision, evaluate, or use to triangulate one's own experience.

I am so glad you were able to receive ultimate satisfaction from CycleMonkey (Rohloff's sole North American Service Partner for the Rohloff SPEEDHUB 500/14, providing warranty service and routine maintenance: http://www.cyclemonkey.com/ ). They're in the San Francisco Bay area, only 13 hours from me by car, so close by mail. Reassuring to know.

I'm encouraged to read that even when problematic, your hub was still relatively quiet while pedaing, and it sounds as if two of your three are acceptable, though "different" from one another. Thanks for this; I'll know to expect some variance and I'll tackle any problems as they come.

The ticking while coasting takes me back to childhood, when I owned a Campus Green Metallic Schwinn Sting-Ray with Rear Slik (sic) that used up a lot of capital letters in its name. It had a Sturmey-Archer three-speed IGH and it used to make a softish, periodic ticking when pedaling in third gear, as I recall, and a more pronounced ticking when coasting. The Rohloff -- in concept, anyway -- sounds a bit like that. Maybe it will trigger more happy memories, but hopefully none of the wheelies that were my stock in trade back then as an 8 year-old.

Thanks for the kind words. I'm eager to see if Thorn can find what is wrong with Sherpa, as the cause completely eluded me -- my first failure-to-diagnose-and-address in over 35 years of cycling. I am grateful for their stellar response and resolution, and look forward to learning about Rohloffs firsthand. I lack all experience with Rohloffs and have never ridden one, so this will be a wonderful opportunity to learn something New.

All the best,

Dan.

My Rohloff doesn't make any noise in the 8-14 gears and a quite low noise in the 1-7 gears.  The freewheels makes a typical Rohloff noise, different from the usual freewheel noises but definitely not louder.

For the differences between different hubs, from my experience, older/early models made more noise than the recent ones, may be some differences in the manufcaturing ?

Say Dan how about you doing a video blog on your build would be interesting to see how you go about things.just a thought. ;)
