Thank's, but for to have same relation that rear 34 and front 24 what tooth i need? 22?dru said:The ratios are on Shimano's site. Using a 20 tooth for 5th (which is 1:1) the hub is roughly equivalent to a 32-12.
Harris Cyclery has them for around $ 300 USD complete.
I haven't seen one broken yet and I have so far found it impossible to make the roller clutch slip no matter how much power I put in. It will slip if it doesn't engage properly which has happened a couple of times, it always happens in the first couple of pedal strokes anyway so I assume it didn't engage properly. Mine's been getting a good thrashing for 4 months now, so far I haven't had to touch it. I do wash the bike occasionally though…mehukatti said:I have also two questions about Alfine:
- How often does the freewheel skip in cross country or trail riding?
- Anyone broke one yet?
itsdoable said:my Rohloff from 1999 is still turning and shifting better than the day I got it, and in that time I've broken a crap load of Shimano, SRAM, Sturmy, Saches IGH hubs, most within the 1-year mark.Wow, that makes the Rohloff seem like a good buy if you can afford the initial investment. I'm enjoying mine, but look forward to seeing the progression of IGHs.
That really depends. I can buy 5~6 Alfines for one Rohloff, maybe more. There is also maintenance costs - Rohloff has some maintenance, the Alfine is essentially "throw-away". If the Alfine last 2 years, then I still have not caught up. With the Alfine, I can "upgrade" every few years, and Shimano has been improving the unit every year. And some people don't like sticking 10 year old parts on a new bike.bsdc said:Wow, that makes the Rohloff seem like a good buy if you can afford the initial investment....
With a 20T rear cog the Nexus 8/Alfine is equivalent to a 12-38 cassette.demolitsteam said:Hi,
I'm interested in shimano alfine, and i have any questions:
- How to calculate better relations gear?
- Where to buy it online at good price :thumbsup:
Thnk's in advance
I need to use chain tensioner, because my bike is full suspension.eric_syd said:I hope you're using a chain tensioner and don't expect to just use horizontal dropouts or magic ratio.
In theory, the half diameter of the engaged part of the ring is constant. By experience, I had a Biopace (more round) on a fixed gear and I reverted to a round one after almost crashing when losing my chain in a high speed downhill.
