curbtender

Hey Robbie , better you than me...

Words cannot express my confusion as to what you actually did down there, and not sure I even want to know. But hey, it apparently worked and got you bonus points with the REI folks as well.

So, good on you.

With the hanger hole snapped off across it's diameter, the only answer was something else to hold the RD. I tried 3 different claws, but all were too far outboard. No RD had that much travel inward to clear the 10mm thickness of the RD hanger.

curbtender suggested I treat the remaining aluminum dropout like the carbon dropout that fits with replaceable RD hangers, and further suggested the Cannondale "H" hanger, because it formed a sleeve into which the dropout fit into, rather than an inner piece with an outer, bolt-on hanger. He supplied the hanger.

I then set about getting the 10mm wide dropout to fit into the 6mm wide slot in the RD hanger. I actually hacksawed a slice off the best I could, then cut off a piece that prevented the hanger from sliding up to where the axle hole would line up with the Radac's dropout.

The created a problem with that "angle of the dangle," The OEM hanger's RD bolt hole was situated directly below the axle; call it 6 o'clock. The Cannondale hanger was designed to do the same, but there was no way to trim the remaining aluminum on the Radac to match that angle, and still have enough aluminum to drill a hole through for each bolt. As it is, the top mounting bolt is through and through, but the bottom mounting bolt actually sits in a notch on the aluminum dropout; simply not enough aluminum there to make a hole and still line up with the axle.

The new "placement" of the RD bolt hole, with the Cannondale hanger, is about 3:30 relative to the original 6:00. It sits forward of the original position, relative to the cogs, and about 1/2" closer/higher. The only way to mitigate this was to run the adjusting screw on the RD all the way in, which moved the RD angle back, but it's nowhere near vertical from the axle.

The RD has a greater "tilt" counterclockwise than it would normally have, and the upper pulley is biased somewhat up in front of the cogs. It's like looking at it from the side, reaching out and rotating the RD on it's pivot about1/6 of a turn counterclockwise. The 13T being the smallest, this could have been a real issue, but with a new chain, it spins forward and backward just fine with no chain slap or suck.

I'm going to give it a good shakedown, maybe 2x15miles or 1x15 and 1x25, just to make sure. Then I'll probably send Rachel at REI the pics, let her test-ride it, and give her a good rundown on the issue maybe being fine forever, and maybe failing the next time around the block. Best case scenario, she rides it at RAGBRAI. Worst case, she finds another frame and swaps over.

As you can see in the picture, the only way to slide the back wheel out is to remove the skewer end completely.

'twas and you knows it. good on ya.

It's been a great ride, I really like this bike! Not many changes so far: Planet Bike Cascadia fenders and a new Brooks B17 saddle (honey). Still waiting on MKS Sylvan Touring pedals, and new Sugino XD crankset. After that, probably some Tektro CR720 cantilever brakes, and as yet undetermined new shifters, brake levers, derailleurs, and stem. I had thought of changing out the bars and grips, but I actually like both as-is.

Will post new pics soon.

This one has its own free-standing post already, but what the heck. 1974 pre-Kabuki (and pre-Submariner) Submariner. Rare to the point of possibly being unique and in drop-dead gorgeous condition. Was trying to get $160 for it locally because I have no good use for it (too many damned bikes), but no takers so I guess I'll have to keep it in the stable. Boo hoo.

Here’s my MB-5. I bought it and a kayak with insurance money after a hailstorm totaled my car. (Got to keep the car too, which ran fine.)

My brother-in-law drove a dimpled car for several years. I'm not sure if he saw the Myth Busters episode, but he claimed to get better gas mileage.

My identical pair of trusty ol' City Limit CB-2s. Recently sold one.

Last year I picked up

1. Cold set the frame to fit a 130mm rear hub wheel
2. Hope my BB will fit (or find one that will)

a 1994 RB-1 in nearly mint condition (still has the cellophane cover over the headtube badge) with mint condition complete period Athena groupset (looks like the guy I bought it from, the original owner, had it built up from new with these parts and then rode it 2 or 3 times over its life).

The groupset is surprisingly nice to ride and shifts excellently but I love old classic steel bikes with modern groupsets and was able to pick up a nearly complete SRAM Apex (missing brake calipers) for $40 and am thinking of building it up with this set.

What challenges am I looking at to build it up?

This is what I know about:

1. Hope the BB fits (or buy one, what size to get?)
2. Cold set the frame to fit a 130mm rear hub.

I would keep the quill stem, but might get a more modern style ergo drop bar.

You should definitely go with the SRAM group. To make it worth your while, I'll give you twice what you paid for the SRAM group plus shipping for the Athena group.

Hehehehe, I need to get a new wheel set too. I hope you aren't in a hurry.

I have a sweet 1990 Bridgestone MB-1. Great bike! It has been sitting unridden for a few years, due to a hip injury, not bike-related. Bike is a little dusty.

Swap you for a nice set of vintage aero-ish tubulars laced to some sweet tri-color Huns.

Got my shredded dropout fixed and rebuilt my '89 RB-1. Today I took it out for a shakedown ride. I had forgotten how nicely it rides--better than I remembered it.

The biggest difference was swapping out brifters with Shimano Aero levers and Dura Ace 10-speed bar-end shifters. The drivetrain is Ultegra 6600.

Love this bike!

^^^Grant would be pleased.

What's an XO-1 selling for these days?

Recent XO-1 sales on ebay. Construction Pumpkin fetches the best price.

Hi, curious to know where you got the decals? Looks great!

gravityhurts

Thanks Sliverexpress!

VeloCals bicycle decals - Quality, Durable, Ultra-thin

Their decal kit is missing the "CrMo" foil decal for the forks.

Anyone know where I can source it?

How do I make this picture big enough to see?
It's tiny?
