Re: [RBW] Wide range 3-speed QB refurbished

Joe, that's why I like the SunXCD better than the TA Pro-5-Vis - the flare in the arms gives it a wider footprint, clears possible contact with chain, chainrings, kickstand, FD cage, and especially Simplex chainguard ("clearance" with the Pro-5-Vis) On Tuesday

I'm a narrow-Q dissenter. The Riv Silver cranks on my Clem H were so narrow that I kept shifting my feet almost off the sides of the pedals. Narrow Q, not for everyone! -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group. To unsubscribe from th

Re: [RBW] Wide range 3-speed QB refurbished

ps - found this on VO blog First, Pro-5-Vis cranks have about the narrowest Q factor, or tread, of any crank made. That's a good thing for most of us. In fact some experts claim that most riders pedal more efficiently on low Q-factor cranks. But there is a small percentage of riders who are mor

Thanks Phillip, I couldn't tell you the math, but they're about as vertical as a crank can get, with the square taper buried far to the outside Here's the reason I used SunTour FD1300 - figured how to attach the Simplex chainguard using a computer board standoff, and the Simplex hardware with o

The accolade of Crisp Front Shifting was given on another thread, and I didn't want to seem to take exception with that accolade where it was given. I'm posting my comments on this thread in case anybody wants to reference it for following up on their own version of James' 3-speed. No front

Re: [RBW] Wide range 3-speed QB refurbished

You are right; with such wide range, there are certainly advantages to 3 rings over 3 cogs, given the designs of the frame and the hub, and given the smaller range of most available 3 speed freewheels (16-22 seems to be typical). FWIW, I've recently set up my 2 Riv Roads with triple gearing (getti

Re: [RBW] Wide range 3-speed QB refurbished

Thanks, Ron. When I first set it up in ‘05, I tried a standard tensioner, and it couldn’t do enough for the chainring differences I wanted. I really demand that granny/grandpa gear. So at that point, I went with derailleur and was lucky that the local bike shop had one that could clamp onto the

[RBW] Wide range 3-speed QB refurbished

Looks great, James! I guess you could have put the gears in the back, but you have a TWENTY TWO tooth difference in the chainrings. You’d still need a 16 tooth difference in rear cogs to get equibalent gears (30x14/19/30), but that would require a cassette hub, a real derailleur hanger, more cla

Re: [RBW] Wide range 3-speed QB refurbished

Just keep in mind that the more tooths there are on a cog/ring the smaller the delta of adding or removing a tooth. This is why I love the 4t difference of the dingle cog, as it gives a range of 14” whereas a 4t difference with the chainrings is less, albeit small enough as to be insignificiant

Re: [RBW] Wide range 3-speed QB refurbished

ps - on 3 of my 4 bikes, excepting the indexed thumbie compact double x 9, I always shift most often in front - using rear as a final adjustment. Two of those are half-step plus granny, but same on my Campy road bike - I usually keep it in one of two rear cogs and shift front for start/stop, or

Re: [RBW] Wide range 3-speed QB refurbished

I like it. Guess you're using RD just for chain wrap. Curious whether there's a chain tensioner with enough chain wrap to cover the ring range. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group. To unsubscribe from this group and stop recei

James, quirky, delightful, purpose-built, and hilarious. I love it that you love it. Grin. Joe, one way to achieve 3 freewheel or fixed cogs is a double (ENO freewheel, Surly Dingle Cog) and third cog on a flip/flop hub. Manual shift, stop required. With abandon, Patrick -- You received this

Thanks, Joe. I think I saw that Cheviot and liked it. Or am I conflating it with Riv Will’s? Because he did this “By One” type deal as well. > On Feb 7, 2019, at 9:02 AM, Joe Bernard wrote: > > James: I've always liked that bike. I double-ized a Cheviot with a single > rear cog, double fron

Because 20/22 is a lot less than 40/32, and I want a LOW lowest gear for steep dirt hillclimbing. Also, the following is secondary and wasn’t thought of in the design phase, but it’s a lot simpler shifting the front since the bike has no derailleur hanger. That cable-less derailleur as shown wo

James: Why 3 rings, fd and rd instead of 3 cogs and rd, particularly since a tooth in the rear gives more difference than a tooth in the front? Not complaining, just asking. On Thu, Feb 7, 2019 at 9:48 AM James Warren wrote: > > I first set this up this way in 2005. I recently made it better wit
