Re: [RBW] Quickbeam/Simple One Gearing Ranges?
I agree. I pedal over to base of Mt. Tam in one gear, switch to the second for the climb, then back to other gear for descent and ride home. I do that a lot, on all sorts of varied Nor Cal terrain. --- On Tue, 1/29/13, Philip Williamson philip.william...@gmail.com wrote: From: Philip Williamson philip.william...@gmail.com Subject: Re: [RBW] Quickbeam/Simple One Gearing Ranges?

Re: [RBW] Quickbeam/Simple One Gearing Ranges?
This is my preferred setup, too - widest Surly Dingle, and matching rings so the axle doesn't move. As Peter points out, you can climb more than you thought in a 70ish gear, and the low gear seems super low. Same-side switching takes seconds: Slide the rear wheel 1/2 forward and tighten the QR, derail the chain with a stick and roll the bike forward to drop onto the smaller ring. The chain is now pretty slack, so you can do the same operation to get onto the larger cog, then slide the wheel back to tension the chain. Ride away.

Re: [RBW] Quickbeam/Simple One Gearing Ranges?
Scot - Yes. I always loosen the axle before shifting. Suppose if you were close enough in sprockets, you might be able to run it slack if you shift down, but if you are running close gearing, you probably are better off just standing up for a bit. I've been toying with the idea of a 2-fer fixed cog, as climbing fixed is always more efficient for me, but there are definitely a few climbs where it's tough to keep the momentum with my fixed gearing. It depends a lot on the type of riding your loops encounter. I've been finding myself riding fixed more frequently on tighter trails, which is another view of the same equation. Ray S also ran/runs a double-cog freewheel on his setup - viewable here: http://cyclofiend.com/ssg/2007/ssg074-rayshine0307.html - Jim On Monday, January 28, 2013 8:45:11 PM UTC-8, Scot Brooks wrote: Here's a dummy question for the experienced 2x2 folks; how do you change the gears when the chain is (presumably) under fairly high tension?

Re: [RBW] Quickbeam/Simple One Gearing Ranges?
I can see that -- two rings and two cogs can give you a considerably bigger range with less chain movement than merely two cogs. I know that when I rode fixed/single off road, finding the right compromise was a hassle. A gear low enough for hills meant horrible flailing downhill and on the flats. I finally settled on a 60 gear and walking more, but even this was horrible on the flats, so I went back to multispeed off road. I still think that I, personally, would prefer a double fixed rear and a single ring, though, this for simplicity's sake.

One thing that has always appealed to me about Rivs was their versatility. I like that the bikes allow for opportunities, enable multiple possibilities, rather than dictate or limit them.

Re: [RBW] Quickbeam/Simple One Gearing Ranges?
I think it is strange to buy a SS and try to get a range of multiple gears out of it. IMHO that's what the QB was designed for; that's why it came with two inch long, angled dropouts, stock double chainrings, and free/free hub so you could add your bailout of choice.It's not a singlespeed- it has always featured 'digital shifting'. I have mine set up with the stock 40/32 up front, and a 16/19 white f/w with a 22t on the flip side for riding steep/tight bouldered and rooted trails in the woods.I don't shift often, but that's not the point- when I do shift, it's convenient to be able to.

Re: [RBW] Quickbeam/Simple One Gearing Ranges?
Here in CT our hills tend to be relatively short and nasty, and I can't ride very far without hitting one. So the ability to shift is helpful if I want to go on a longer ride or explore new roads. I have a couple of 15 mile routes that I can do in one gear, and I ride them frequently as I rarely have more than an hour to ride anyway, but longer than that and I'd need to climb something. Also, my local roads tend to be narrow and winding with no shoulder. I feel less safe (rationally or not) pushing a bike up a hill in that scenario than I do riding it. That said, I can do my normal 3 mile commute in one gear, so that, plus my typical short, flat routes means I probably only shift on one in ten rides. But if I limited myself to what I use 90% of the time I wouldn't need more then one bike, or a fly rod, or a 35mm film camera, or an espresso machine. And what's the fun in that? So I surely could get away with one speed, but having the options has no down side to me so why not have them? And there's always the fantasy of the someday, future Quickbeam credit card tour around New England...

Re: [RBW] Quickbeam/Simple One Gearing Ranges?
Mine's the 40/32 - 16/19 with a flip side 22 as well. I've used the 22 exactly twice. But darn, I'm glad I had it. Both times were when I was fully loaded with camping gear and tackling a BFH (oddly my initials when using Bob instead of Robert and Big F'ing Hill. I'm glad I had it. When I first got the bike I rode 40/16 pretty much all the time because many of my rides were of the longer weekend sort. As I kept at it the QB became my commuter bike and I found it's much easier for me to ride start and stop city riding in 40/19. I have a bit of arthritis in one hip and it's wee bit too stressful to try for quick starts at lights with traffic behind me. With 40/19 I'm good to go and frankly, since mostly I'm only going to go a couple of blocks before I have to stop another light I don't tend to spin out (which I do just over 15mph in that gear). These days I use my Hunq for loaded camping so I wouldn't really need the 22, but there's no real point in taking it off. If I have to rebuild my rear wheel I'll probably do that and perhaps go to a 16/18. Of course, now that I've spent all this time thinking about it I may have to go back to 40/16 just to see if my legs are stronger than they were last year. The more I ride the stronger I am, the more I age (55 currently) the weaker I am. If I can stay even I'm happy. :-) Aloha, Bob On Tue, Jan 29, 2013 at 9:25 AM, Matt Beebe matthiasbe...@gmail.com wrote: I think it is strange to buy a SS and try to get a range of multiple gears out of it.

Re: [RBW] Quickbeam/Simple One Gearing Ranges?
I find the two rings make things simpler than not. The chainline is better in each gear; the axle doesn't move, so the fender line is good; and if you're maxing out the tire width at the chainstays, you don't have an issue as the tire moves. The only complication is a heavier, more expensive drivetrain, and the OCD desire to have 0 axle movement.

I know that when I rode fixed/single off road, finding the right compromise was a hassle. A gear low enough for hills meant horrible flailing downhill and on the flats. I finally settled on a 60 gear and walking more, but even this was horrible on the flats, so I went back to multispeed off road. I still think that I, personally, would prefer a double fixed rear and a single ring, though, this for simplicity's sake.

Simple answer -- yes. For inspiration, consider Eric Norris (campyonlyguy), who rode across the country and rode the Paris-Brest-Paris on a QB with only one fixed gear.

Re: [RBW] Quickbeam/Simple One Gearing Ranges?
I have the 40/32 and 16/19 on my QB and have a couple of observations. First, I run the 40/16 most of the time and can climb much more than I ever thought possible in that range. Second, the 32/19 feels much lower than i thought it would. Also, you can always put a 22 on the flip side of the Dos as a bail out option. If you need lower than that then just walk. I've found that large part of the QB ethos amounts to becoming one with just get over it!
