Re: Is this good enough for a fully loaded camper longflap??

Re: Replacing 26t inner with 22t

I used 52/38/24 with no trouble using an Ultegra front and rear mechs 28teeth admittedly only with a 12-25 cassette. Try it and see an inner ring is only a few pounds (see Spa Cycles) it is surprising what works in spite of the makers specs.

Re: Shimano Alfine 11 - Longer term reliability

concentrate on making the selecting mechanism for the gears as part of the hub, rather than the speed controller


See Rohloff hubs cable adjustment the selection takes place inside the hub ours has done 13000 miles so far.

Re: crankset stiffness

Mick even if everything were completely rigid, such a crude system as derallier gearing which just works by pushing the chain off one sprocket/chainring onto another while mounted on on roads that are anything but smooth, is bound to fail now and then.!!! Also I wouldn`t say that 94 revs can be cons...

Re: Elliptical chainrings and dodgy knees

Shorter cranks also help knees ,that and not having the saddle too low as already mentioned.

Re: Shimano Alfine 11 - Longer term reliability

Just a personal thing ,I have always just eased the pressure when changing any type of gear whether hub or derailier or car or motorbike it make engineering sense. It only needs to be a slight easing of power, therefore no loss of speed but a faster change with no breakages.

Re: Leg extension...what do you think?

Maybe you only need three measurements- Seat tube-Top Tube-and Headtube which determines how low or high the bars are

Hi We have covered about 800 miles on our Rohlhoff tandem, and it works really well for us. I agree wth the contributor who says you don`t really need to know which gear your are in as there is no need know when to change chain rings or if the chain is running too far out of line. The ratios are the...

Hi Try Ergon grips on flat bars they have all the difference, they stop you flexing your wrists which seems to cause some of the discomfort problems.
