hi all!
i was inspired by the front shifter quickbeam in the riv reader by james warren, so i made mine a 10 speed. i bought a used araya 120mm 5sp freewheel wheel and 14-28 freewheel and cabling for 40 bucks at the lbs. already had the derailer and shifter. couldnt be happier. i imagine this is what an ahh feels like.
anybody have any advice on cable routing? is it better to go on the downtube?
thanks for your time

I suggest a hybrid of your routing and old, 3-speed cabling as shown here:


You'll need a cable stop for the top tube, a pulley for the seat tube, and a cable stop for the seatstay. All are available at Harris Cyclery and should cost you about $15.  Much cleaner than all that housing.

I'll bet Grant is laughing his arse off. He built a frame with no braze-ons which fits old 5-speed wheels. Just like all road bikes used to be!

Mine's gonna get steel drop bars with foam grips, and those brake levers with the second lever on the inside. ;-)

Oh, that is so great!

I'm seeing that with a bit of regret. I was going to try this with my QB and a 5-speed freewheel, and even go 3x5 for a 15 speed!

But the shop talked me into 11-speed Alfine. I'm happy with my decision, but now seeing how great your bike is makes me wonder what could have been!

And yes, a multi-geared bike with QB geometry is what I've been dreaming of also.

It's really fun to see all these different Quickbeams. What a great bike! Great job!

Another option.  I ran a four speed QB with the double up front, and Dos Eno cog in back.  Thumbshifters and front and rear Der and I finished a century with some friends.

I found the clamp on chainstay cable stop on the Web, and the bottom bracket on my silver Quickbeam has cable guides.  Riv sold a downtube clamp cable guide (still may...).

Nice. How much trouble is it to take the rear derailleur off on the road if you get a flat?

That's really cool. There's something about the Quickbeam that makes
you (me anyway) want to tinker with it. Maybe it's that it comes with
two gears and no shifters, so there's an implied permission to break
all the rules! :^)

Not long. Just need to have the correct wrench in the bag. I'm usually out by myself and hope the flat occurs near a pizza joint...
