Davidson bicycle
 
Here is my custom built Davidson 2007, one of the most detailed work done by them. I ordered it based on making it look like a Peugeot PX10. The frame color is a beautiful pearl white done by their painter Ryan
farrell. It has newvex lugs, fork crown and tang. Pacenti drilled bottom bracket and brake boss, campy ends, and custom painted stem. The frame is made of Reynolds 853, the decals look like the old Reynolds 531 but says 853 instead.

Wow! Very nice. A real "sleeper"...

PX10 was a nice riding/handling machine but had a typically lousy French paintjob!
Peugeot never built a bike as nice as that Davidson-look-alike!
Pedal on!

Oh wow thats a very detailed frame... Just outta curiosity, what size is it?

jimc 07-17-08 01:56 PM

Its a 56mm--same size and specs as Bob Freemans black beauty at Elliot Bay Cycle in Seattle. You can see that bike at cyclofiend.com.

I see you have a Waterford. I can't believe it weighs only 20.5 #. That reynolds 953 must weigh alot less than 853, because mine weighs 21#,and is alot shorter than yours.:thumb:

Thanks.

I don't believe there's a significant difference in weight between the 853 and 953 tube sets (generally, 953 tubing walls average about 0.1mm thinner than 853 tubing walls). My frame by itself (no fork, no BB, no headset) weighs 1650 grams (a little over 3-1/2 pounds), and I'd bet your frame weighs less than that.

I notice you have a triple crank and some alloy components. I went with Campy Record carbon and a compact double, so that's part of the difference. Don't forget, the paint weighs something, too. ;)

Your right, my campy triple, 700x28 gran bois tires. Pauls centerpull plus hardware, and the paintjob add for the weight differance-thanks Jim:D

That is beautiful. I've been a fan of lugged steel for over 20 years, and that's a bicycle I'll remember. It looks comfortable and fast. I love the lugged stem and the bottom bracket.

I actually just moved to the Pacific Northwest from the East Coast about a year ago, and I've been admiring Davidson's work online... and in person during the few times I've seen one on the road or in a shop. I turn 40 in three years, and I've already told my wife that I want a custom road bike with a sport-touring geometry. I think a Davidson would fit the bill nicely.

jimc 07-25-08 10:20 PM

Thanks--this was my birthday gift to me with the approvel from my wife last year. I allways wanted a bike like this since I was 14 years old but was never able to afford it. I'm older than you so I won't tell you my age, lets just say my 25 year old son is drooling to have this beauty, but not until I can't ride no more. Hope you enjoy the Pacific Northwest--It rains alot:(--but we appreciate the sun more than anyone when it does come out:)------regards jim

That is so beautiful thing I have seen in a long time, I have a friend that actual had 3 PX10s, it looks so much like them, but so much better, I love the detail. I have an old Davidson Impulse, love the bike, not even close to the detail, but still great, after seeing this, & want to get another one, one that is actually custom for me, with some great work like that.

Does that happen to have similar geometry to the PX10?

I don't think so, PX10 was a race model. My Davidson is built for sports touring, longer wheelbase,and softer ride and accomodate larger tires, I think up to 32mm. To get the exact spec of my bike you will have to call Elliot bay bicycle in Seattle for Bob Freeman or Bill Davidson himself. I happen to get on one of Bobs bike and said I like this fit--and they copied the exact spec on his Black beauty. I hope this helps, I'm not much of a numbers guy------regards jim:)

Great looking bike!

For anyone who hasn't worked with Bill or Bob before, they're terrific to work with. Their shop is *always* worth a visit; there are always 3 or 4 beatiful, interesting customer bikes on their way out the door.

I was in the store last night getting fitted for some new shoes / pedals and there were two or three steel bikes headed out the door, and a 30-year-old Davidson they had just repainted.

cf handlebar and Ksyrium wheels seem out-of-place on such a retro frame. It'd look better with a Nitto bar and some 32-spoke wheels.

I'd hate to be around when that frame gets its first scratch -- that'll hurt. :-(

Thanks for the comment--the Solida handlebar is aluminum, just fake cr wrap on top. Yes the Ksyrium do look out-of-place, but they are bomb proof. I am now looking for some nice retro wheels--any suggestions--thanks jim:thumb:

I have the original wheels from my Davidson from 1981. But I ride it with Velomax Tempests with a 10sp cassette. I have since replaced the brakes/levers, the saddle and seatpost (these two just last night) and pedals, and rewrapped the bars. The Campy NR is staying! The tubing is Columbus SL. I need an updated picture. Maybe I'll take one tonight.

I'm thinking of putting different bars on it too. The bend on these just doesn't feel right compared to my new bike.

Wow a vintage Davidson, looks great still. I can't believe your using campy NR on a 10 sp cassette, didn't think it had that much range. I decided not to change my Kysrium wheels for retro looking ones, the wheels just ride to good with this bike, they are durable, light, fast, and expensive--maybe better than any retro style wheel custom built or bought at any lbs:D----jim

zacster 08-01-08 10:53 AM

The only problem with the 10sp cassette is I can't get onto the largest cog. You're right, it doesn't have enough range, although it could be I have a little more play but the screw is stopping it. In any case I never use the large one. It otherwise shifts a LOT better than you would think. You only have to move the shifter a bit to get it to shift, and it is very quiet when it does. In fact, it makes me wonder why we needed indexed shifting in the first place. The chain/cassette has more to do with the clean shift than the brifter does.

Interesting modernization. Having restored my vintage 80's Tommasini back to its original condition, I've now decided to change course. I want to put on a compact crank, a 10-sp cassette, and modern wheels...keeping my downtube Campy shifters, non-aero brakes, and Campy derailleurs. By coincidence, I'll likely have the folks at Elliott Bay do the work (though they may shoot me for putting on a compact crank...).

My current crankset is 53/43 chainrings...which is a struggle for me if I head up into the hills, and I would like to use my bike up in the mountains on some longer rides.

zacster 08-01-08 08:35 PM

I have another bike from the same year that I've kept in original condition. That one has Campy SR pantograph components. I wouldn't ever change anything on it.

The Davidson OTOH was always a mishmash of components, since I was paying for each of them when it was built. Some were high end for the time like the Campy NR, some were not, like the Modolo Speedy brakes. I had no qualms at all about replacing the Speedys earlier this summer.

As for the compact crank, 10sp wheels that you are looking at, wheels can easily be swapped in or out, so you can keep the vintage look. Cranks are harder.

Use 10sp Shimano wheels and an Ultegra or DA chain and keep the gearing reasonable. Don't use Campy. Shimano is a little narrower so it works better with the NR derailleur. Keep the shifters as I did. The brakes I put on are aero style Tektro. Cheap stuff, but it works well, looks good and feels right, just like Campy.
