Re: [RBW] Re: chain line and the Quickbeam

I used a bb lockring on the Suzue hub freewheel threading to make it more difficult for a fixed sprocket to back itself off. Worked fine. But, I was still using the rim brakes rather than engaging in high-pressure backpedaling to stop. Since switched to a Phil which is fixed/free and now us

Re: [RBW] Re: chain line and the Quickbeam

Thanks for the tip guys. After reading this I today set my 'beam up with spare parts. I now have a 42x22 fixed/free flip flop. Jason Leach SF, CA > On Oct 26, 2014, at 7:19 PM, Kainalu wrote: > > Suzue! And I said Suzie, don't even know what I'm rolling... Thanks for the > great chain tric

I've always been lucky with chainlines. "Oh, cool, that worked." Or else I just don't get into it unles I have a problem, and haven't had any problems. I'm still on the QB's original BB. I've also happily run fixed for years and years without lockrings, but I may have been lucky there, too. I u

[RBW] Re: chain line and the Quickbeam

You can use the rotafix method to install and remove fixed cogs without the need for a chainwhip. It uses the wheel as leverage which gets far more torque than a chainwhip. I've used this method to setup fixed gears for myself on a regular freewheel threading and have never had a cog come loose

[RBW] Re: chain line and the Quickbeam

That makes sense, you could use another cog on there as a lockring of sorts, and if you carried a chainwhip you could swap your fixed set. Or I suppose you could use your crank and chain as a chainwhip just as easily by using a stick to brake the crank. There must be a thread around here somewh

[RBW] Re: chain line and the Quickbeam

It's free/free, and I have a 22t free on the flip side. I was told I could put on a fixed gear and it would work fine so long as I didn't do aggressive backpedaling to brake (since I have brakes) -- so that's my plan for "someday" when I try it out. But I definitely like having the freewheel fo

[RBW] Re: chain line and the Quickbeam

Well worth the effort then, and you're never at a loss for torque. The Phil hub is freewheel/fixed? Or freewheel/freewheel? I was thinking fixed would be fun in the snow and ice but the suzie's lacking the fixed locking side. Might have to find a relatively cheap fixie rear wheel to try it out,

Thanks Patrick, I knew you'd have the answer, and with wild abandon. And I'm glad we're gearing buddies, mountain gearing's what I'm after. If I can coax it out of the dropout I might stick something racier on the other side for downhillin. You said something about Allen wrench gear shifts befo

[RBW] Re: chain line and the Quickbeam

Mine is a 113, as it came standard from Rivendell, and I have the same gearing set-up you describe. My chainlink is smooth in both high and low gears. I don't cross chain, so can't speak to that, but expect it would work since the others do. With abandon, Patrick -- You received this message

[RBW] Re: chain line

Good to know, thanks. I tried measuring, but I'm not too confident in my plastic ruler and less than perfect eyeballing skills. Best I could tell its ~46 mm from the middle of the seat tube to the inner face of the middle chain ring. I'm sure it'll be fine. Jay On Thursday, June 26, 2014 1:21

[RBW] Re: Chain Line

Measuring chain line on the rear cog can be tricky, indeed. It's why I gave up years ago and bought a Park CLG-2 chain line gauge (discontinued, apparently - don't know what their substitute is, if any). BTW, they have a pretty extensive discussion about chain line measurement and shifting/no

[RBW] Re: Chain Line

Thanks for all the input. I tried the magic gear thing and couldn't make it work. Looking at the calculator, I think I now understand why. It shows my 40/16 gear as a perfect match with a 100 link chain and the Sam's 45.5 cm chain stays, as long as there is zero (0) chain stretch. It's way off w

[RBW] Re: Chain Line

Measuring chainline on the rear cog can be tricky. My preferred method is to put a straight edge of some kind across the locknut on the driveside and measure the distance between the straight edge and the centerline of the cog. Then, chainline=(Over locknut spacing of the rear hub)/2 minus (d

[RBW] Re: Chain Line

BMX single gear sprockets will fit onto a Shimano splined freehub. It should run reasonably quiet, but if you have a derailleur in the mix to maintain tension, it's not going to run silently. Also, if the chain has been degreased and is a bit dry, it can tend to clatter a bit. One thing I do

[RBW] Re: Chain Line

The term "track cog" baffled me. You have a single cog on a cassette hub? My original Quickbeam chain was really noisy, but the new chains have been quiet. I would see if I could put together a "magic gear" and eliminate the derailleur or tensioner entirely. http://eehouse.org/fixin/formfmu.php

[RBW] Re: Chain Line

Thanks, Blakcloud. I'm laughing at the term "spacer kit". I raided a bunch of worn out cassettes for spacers and a few cogs to fill in. I did the lockring like I would for a cassette and it seems tight to me. Cog is Shimano XTR, this one http://www.amazon.com/gp/product/B000R39902/ref=oh_detai

[RBW] Re: Chain Line

I just eye ball it, If it looks straight it probably is. Sheldon Brown has a great article on measuring chainline. If the chainline is off it doesn't rattle, it just makes some noise but it has to be really off to do this. Typically 8/9 speed chains ar
