Re: LOUD hub for Triban RC500

I heard there're people, who make new, stronger spring for pawls out of this ring for keys. Quick googling didn't bring up any tutorial, but you could give it a try, if you understand what I mean. Actually, I'll be servicing a freehub soon, so maybe I'll try it myself, jut out of curiosity :p edit: ...

Re: V-Brake overhaul

Another thing to consider is hooking springs in another hole of the pivot, to tension them even more - it sometimes help with centering problems. The problem that I encounter with cheap v brakes is often that the adjusting screw misses the end of the spring - either because the part it's screwed int...

Re: Shimano Alfine 11 - Longer term reliability

I haven't yet worked on Alfine 11, so maybe it's better to wait for Brucey, but just to clarify - these modules don't turn all the way when everything is assembled, or you can't make the gears turn freely in each module, when it's disassembled? If it's the latter, then it's definitely a sign of some...

Re: Shimano Alfine 11 - Longer term reliability

The part you circled is a clutch, which engages in gears 7-11, so it being faulty on its own shouldn't cause symptoms you wrote about. If I understand correctly, the gears in that part with 2 roller clutches spin up to a point and then get stuck, right? My guess is, that metal parts from worn clutch...

Re: Grease is the word; a complicated word...

I was talking about using it in ROLLER brake. I also tend to think, that it doesn't t really matter that much, but my perfectionism doesn't let me leave it (even though the only rollerbrake I ever serviced was fine with standard Nexus Grease :p). Maybe next time I'll get to service one, I'll buy tha...

Re: Grease is the word; a complicated word...

Okay, thanks for reply. To anyone interested, after looking at this video: https://www.youtube.com/watch?v=H9_Llzcz2cY how I understand it is that, when we assume that input's rotation speed (our cadence) and torque (we're tapping along) is constant, then ratio is in inverse proportion to torque on ...

Re: Grease is the word; a complicated word...

Okay, so, from what I understood, the reason for those high loadings, in comparison with cars, are: ⋅ riders not using "clutch", that is gears, the right way (whereas in car, given the rotation speed differences and torque, it'd soon destroy the gearbox. Am I right, looking at it...

Re: Grease is the word; a complicated word...

I have yet another question to you, Brucey :P. It's concerning the right grease for IGH. In one thread you said that Bicycle IGHs are characterised by very low speeds, low temperatures, extremely high loadings.[ Could you elaborate on that high loadings part? I mean why are they higher than the ones...

Re: Shimano Nexus 7; how it works. (long)

I just found out, than on Hollandbikeshop.com there's a product, that seems to me like a bearing race for Nexus 7, price is also not that high. It seems, that right bearing is a part, that fails most often, so I think it's a good news :). edit: it's this one: https://hollandbikeshop.com/en-gb/bicycl...

@Karx
If it's just that, than here: https://www.youtube.com/watch?v=ynHJIGTvcwg&t=1851s you have a nice video, showing how to put a psring back - maybe it'll give you some confidence.

Re: Sachs Super 7/Sram Spectro S7 hub; No Future?

I also read, that older Sachs hubs used same keys, and from the drawings, they look like those thicker ones.

Re: Sachs Super 7/Sram Spectro S7 hub; No Future?

I was recently working on a Super 7 that did not shift down, after passing 5-6th shift (the rod engaging sun gears wouldn't back up). Had to open it 3 times before I found out what was the cause - someone before me has switched places of axle keys. The right order is: narrow one on the drive side, t...
