In every instance I've witnessed, it's a dark gray.
I posted on here my ongoing problem with my 2019 R&M Supercharger e-14 where after 1 year it leaked out all over the E-14 , sent it back to Rohloff for repair , and after a year , it leaked once again , same place, spoke to Rohloff and again it looks like I am going to have to send it back via dealership , asked them if this is going to be the norm, their answerWe have two 2019 R+M Nevos with Rohloff and both started leaking oil like a sieve after the first oil change at 3,000 miles. The oil leaks on the drive side and gets all over the E-14 and skewer. Every time I fix a flat, I have to wipe everything clean and clean the rotor.
I think the oil leaks through the vent. I replaced the seals under the E-14 when I had to remove it to rebuild the wheel when the rear rim cracked. The seals all looked perfect. We have taken the bikes to and from high elevation (6,000 to 10,000 ft), which probably causes some venting.
I agree with some that say you should not replace so much oil in the Rohloff hub at an oil change. I understand Rohloff recommends the 25ml quantity of clean oil to reduce hub noise, but our Rohloff's are very quiet. I think putting in 10-15ml of oil is probably plenty - as for sure adding more will just leak out anyway.
Did it start leaking after an oil change?I posted on here my ongoing problem with my 2019 R&M Supercharger e-14 where after 1 year it leaked out all over the E-14 , sent it back to Rohloff for repair , and after a year , it leaked once again , same place, spoke to Rohloff and again it looks like I am going to have to send it back via dealership , asked them if this is going to be the norm, their answer
I regret that I cannot comment on whether this current/new oil leakage is from the same are and components we replaced last, or from other areas - we would have to receive and review the unit before we can comment on this. The large SPEEDHUB seals are exposed to the elements though so there is always the possibility for hairs, grasses or other external foreign particles to get caught under the seal lip, creating a bridge under which oil can leak out, or even to damage the actual seal itself. As such, I am unable to answer your question about the expected intervals in which one could expect to have to re-seal a SPEEDHUB. Some of our customers send their units yearly. Some never send them. There are simply too many variables involved to provide a clear answer to this.,
I also wrote to R&M sending that reply , and asked them if it was except able to do this every year with my Supercharger plus the costs involved , if I was to fall into the Rohloff, Some of our customers send their units yearly. category , waiting for R&M to reply, basically an expensive bike that could require having its gear hub repaired each year ? is it common fault, who knows .
Interesting, 10ml is the recommendation of the official technical service partner here in the states, and we've not seen any leaking after oil changes since switching to this recommendation, even on hubs that were having leaking issues beforehand.No , after approx 1 year after Rohloff repair , did an oil change last week with a long overnight drain to see what was in the hub, not a lot, put in 20mil , went on a long ride, it leaked out all over the e-14 area , did a ride again , same thing, spoke to some experts on the subject like Thorn UK who have been in the Rohloff business from the start , They say it does not sound like the usual over fill issues , misting etc, given the quantity of oil loss .
This jives with our success only putting 10ml back into the hub. I think sacrificing a neglegable amount of noise dampening (we've not personally observed a difference between a hub with 25ml vs 10ml) is worth not having the hub puke on the floor every 5000km.The official line with Rohloff , Although the SPEEDHUB has 25ml of oil within it, the hubs only actually require approximately 7ml for lubrication. The remaining 18ml is only included to help with noise damping. This 7ml of oil that the SPEEDHUB requires will never be lost completely because the oil properties allow it to cling highly to the surface areas of all components within the SPEEDHUB. Even after extracting the oil with the syringe, this amount of oil can still be found within the gear-unit. For this reason "The gear unit can definitely not be damaged from riding with too little oil". As long as the SPEEDHUB was originally filled with oil (i.e. not dry) and an oil change is made at least every 5000km (to guarantee that any penetrated moisture is rinsed out), then the gear-unit will continue to run flawlessly
Hi, how are you doing with your e-14 , just asking as i am now into my 2nd major leak inside of 24 months and have my dealer now sorting the return of the hub to Rohloff , plus making waves with R&M once I get the repair report back , unfortunately my bike is now outside of shop warranty , any further info would be most welcome to strengthen my argument re: why all the leaks ? cheersI also experienced this (severe leaking). Larger size drops that ran over the E14 before hitting the floor.
1. Temperature changes played a role, notably from cold outdoors to bringing the bike indoors. Presumably the pressure increased as well. The leaking was most severe after a ride in the cold.
2. I learned that the external seals were once considered regular maintenance. The seals and tools were available to the end user. No longer. I consider it unacceptable to have to send the hub away for this service.
Leaking would be much easier to ignore if these bikes were kept in garages with dirty floors, but many of us keep these expensive bikes indoors. I was asked not to bring the bike back to a conference room I use at work after an "incident." The drainage path over the E14 presumably could be diverted somehow -- I don't know if anyone at Rohloff is looking at this since, the party line response is that the hubs don't leak significantly.
My problem was resolved with a new/rebuilt hub. Should this start up again, it'll probably be the end of my relationship with the hub.
I noticed the Australian Rohloff guy told someone that an oily skewer suggests defective seals. My skewer was and is oily since day one.
