Re: [RBW] IGH on a touring bike?
the idea is there is a scott model called the sub 10. it has a gates belt, alfine 8, disk brakes and good geometry numbers for me. furthermore it looks like it has the right clearances and drop for 650b and fenders. if REI clearances them in the fall i might pick one up -- You received this message because you are subscribed to the Google Groups RBW Owners Bunch group.

Re: [RBW] IGH on a touring bike?
Nick, my daughter's Nexus bike came with 44T chainring and a 20T cog. This gave her 31 to 96. The swap displaced everything shorter by a gear step. There are some short very steep hills in my neighborhood and getting home is always the hardest part of a ride from my house. The shorter setup also agreed with Sheldon's description of where you want your gears. With the current setup, 6 and 7 are 63 and 73 - cruising speed.

Re: [RBW] IGH on a touring bike?
You're probably right. Also the stock cog is a 20, not 22. So with the two rings, I get from 20 to 106. Disclaimers: I used mostly parts on hand, so the crankset was from a projected AHH build that never happened. Or, to put it another way, I didn't really plan the gear range, but I knew I wanted to be able to go real low for the hills around Berkeley. I usually cruise in the 4/5 on the big ring. Dropping from there down to the 28 ring when hitting something steep has been pretty sweet. So, yes, the 20x8 + 44 is probably more rational :.) But every once in awhile it's fun to rev up to the 106 and pace roadies, until my fat self runs out of steam :.)

[RBW] IGH on a touring bike?
I have been bouncing around an IGH concept. Does anyone tour on an Alfine 8 rear hub? The setup I am looking at would get me a low gear of about 28 inches and a high gear of 85 inches. That looks great for commuting but maybe not enough for touring. Does anyone tour on the Alfine? -- You received this message because you are subscribed to the Google Groups RBW Owners Bunch group.

Re: [RBW] IGH on a touring bike?
I break rear drive trains. A lot. I used to break axles on 6 speed freewheels with regularity. Solid axles. My commute involves a lot of hill climbing, including a really nasty one in front of my house, as well as carrying heavy loads home from the store. I ride in all weather, and a lot of rain. When I say that I mean that I ride during the middle of the thunderstorm, not just that I ride during drizzles. I started commuting on a nexus 7 speed once getting freewheel parts became a pain and conserving the ones I already had a priority (this was back in 2000 when things looked really bleak on that front). That hub lasted without issue until I replaced it with an 8 speed nexus. Neither hub has had any issues except for the cassette joint and the shifter, which were minor. The nexus/alfine hubs have one of the strongest axles available in a rear drivetrain for standard bicycles. The mechanism, if properly lubricated and adjusted, is the one of the most reliable large range mechanisms ever designed. The only people who regularly break them are large 29ers riding them aggressively off road with a below-spec chainring-cog ratio. These people also break everything else, and usually break the same part, a pawl. The shifter selection is still lame but bar end shifters (jtekengineering.com) and now lever shifters (hotrodbicycles.com) as well as brifters (sussex.com.tw/versa.html) are available. The other advantage from a touring point of view is that shimano is now making roller brakes that were clearly designed for electric bicycles. This would give you the option of an all weather touring brake that can easily be removed from the bicycle, and that has a heat fail mode that is non destructive of the brake itself (you set the grease on fire). The roller brake is also dirt cheap and indestructible compared to a disc brake, and much simpler to set up and maintain. The issue with having a high enough gear range is simply: how fast do you need to go on a long downhill? You have enough range on the nexus for everything else. It usually isn't a good idea to race a heavily loaded bicycle downhill in an area you don't know very well, and the issue tourists usually face is controlling their speed rather than spinning out. With the nexus you simply stop pedaling and let the weight of the bicycle (that you sweated to lug up the hill) do the work for you.

Re: [RBW] IGH
Axle alignment technique? I haven't heard of that one before. Usually I just tension the drive side, apply enough torque to hold the position, screw down the non drive side, tighten the drive side, then tighten the non drive side. Am I missing something? On 2010-02-19, Jim Thill - Hiawatha Cyclery thill@gmail.com wrote: IME the Shimano 8sp hubs are just fine, though I recommend regular maintenance, since water, grime, and corrosive elements do get in and cause problems. If you are accustomed to single speeds and dérailleur bikes that are decently maintained, and you are inclined to vigorous riding, the IGH may feel like a friction box. I notice that wheels with the 8s hubs come quickly to a stop when I give them a spin in my truing stand, unlike non IG wheels that spin for a long time. They are indeed more troublesome than a single-speed for wheel remove/replace. There is a shift cable that may or may not require tools, and there is an axle alignment requirement. Obviously, it's a technique one can master with practice. We have sold many IG setups to customers, and many of those customers are satisfied. But I choose not to use them on any bike I ride regularly. On Feb 19, 10:45 am, PATRICK MOORE bertin...@gmail.com wrote: But does this caution apply to the various 8 speed hubs?
