Opinions Needed from my Loyal Reader

Actually, this involves TWO semi-related subjects. The first is the practical question of how much is a reasonable offer for a broken bicycle. The second is how to induce a "teachable moment" to people who've been hit by motorists recently, and on more than one occasion.

FIRST OPINIONS

Right (Drive Side) Crank Arm Looks OK. Left Looks Like "Toast"

The bicycle in question is a Specialized Roubaix. It's got a carbon frame that's too big for me, that was involved in a collision with an automobile (more on that later in the second subject) when the whole bike had about 100 miles on it. The crash broke the carbon frame seat tube. It also bent the left crank arm and the wheels are out of true. The condition of the carbon fork is unknown. Those with long memories, will remember that I've noted here how to verify the condition of a suspect carbon fork.

Road Rash on Rear Derailleur. Otherwise, Pretty Much What You'd Expect from a New Bike After a Week of Me Riding It

So, why would I consider paying ANYTHING for this? Well, the first item is that Buddy uses SRAM and the remnants of the bike in question use SRAM. What's more, last winter, I bought a ten speed SRAM Force set of shifters, for a future road bike upgrade and this bike has a ten speed rear cassette, along with a SRAM rear derailleur. It's also got a nearly new SRAM ten speed chain. The bottom line is that with a SRAM rear derailleur of any model, I'll have all the parts needed to convert the road bike from an 8 speed Shimano to a 10 speed SRAM system. That would leave the fleet Shimano-free with the exception of Frankenbike which is an entirely different subject. With the cassette, I'd be able to also have a full backup mud/snow set of wheels for cyclocross and snow weather. And chains are a wear item that one will certainly use as the miles pile up.
Stuff I could use almost right away include the rear derailleur, and the chain (Buddy's got nearly 4k miles on its current chain).

Stuff I MIGHT be able to use include the wheels if I can get back into true (by no means certain) - for my knobby tires when it snows around here, and the carbon seat post as an upgrade for the aluminum seat post on my road bike. Not that I'm really LOOKING for a carbon seat post or even for an extra road bike saddle. Also the tires, which look nearly new and those of us that use such up will eventually use any such items that come our way.

Stuff I think might be saleable would include the SRAM Apex shifters, front derailleur (it's a braze-on type which none of my bikes can use), handlebars, possibly the front fork, and the Apex brakes. I do not think the brakes would work on any of my older bikes due to the evolution of brake reach through the years. Still, some person would probably find late model brakes attractive, even if "low end." Of course, I'm really not thrilled with the idea of getting into the parts selling business.
Before I looked at the bike, I said I'd pay $100 sight unseen. That mostly gave value to the rear derailleur, and little for the wheels or drivetrain. Upon seeing the bike, the wheels look like they might be salvageable as a labor of love (they wobble, but there is no VISUAL damage to spokes or the rim), and the drivetrain without even love being needed. I'm not sure the rest of the crank system is even worth a serious dismantle, since the left arm hits the left chainstay. Even a visually good BB is suspect in such a situation. Or so my thoughts go.
Looking at the bike, I add some value for the shifters (almost new SRAM Apex), the handlebars, which are standard, the brake calipers, which are also new standard Roubaix items, and the seatpost, which I think I'm inclined to sell.
SO, y'all, what's the right amount to offer? This guy thinks a NEW, full Apex system is worth $500, and looking at eBay, I'm not sure I'd argue seriously about that. Still, I've already GOT better shifters and wheels, and am not really looking to get into the parts business, so I think the proper value is somewhere between $100 and $300. Over $150 and I think I start to lose a lot of interest and start simply looking for a good, used SRAM rear derailleur. HOWEVER, if I pass, one of y'all might want to sign up for all this? I haven't asked if the person in question wants to ship if you are not local to the DFW area.
SECOND OPINIONS
This bike comes available because the rider got hit in a "left cross situation." I didn't ask, but I suspect the rider was in the "zone of invisibility" at the far right edge of the lane as he was at the stop line. Simply moving left to be more visible might have converted a collision into a situation not even worthy of mention. Coincidentally, I had a pleasant "flat tire and quick release" experience this week. WHAT? You might ask. Well, it wasn't MY flat tire. A fellow bike commuter had a flat tire and I was fortunate enough to come along and help, without even getting cold and dirty. The RELEVANT aspect was that while he fixed his tire, he mentioned he's been hit TWICE by cars. I mentioned back I could help with that and was a bike league cycling instructor.

Joey Fixes His Tire. Buddy and Steve Offer Advice and a Tire Pump. A Tube was Ready if Needed

The question I put to my loyal reader is how do I turn these into "teachable moments?" Two people who ride bikes and three hits by cars is NOT something I can easily ignore, especially since my last real close call was back in the 70's. Motorists may not necessarily LIKE the way I ride, but they absolutely KNOW how to avoid an actual contact. HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
