OK, sorry for the mix-up. (BTW, my crashed Motobecane was also a Grand Record, began life with Shitmano 600 garbage I quickly wore through and slowly replaced with Campy SR. Then crashed and it became a hat-rack for a while...)

I too have a stuck seat post and did some reading. In my case this thing is stuck, I suspect because the elderly grease on the post did not stand up to the humidity in the garage where the bike hung out for the last , well, forever... I am told ammonia will break the corrosion and free up the post.

I'll get it a try tonight and get some pictures. I need to pull the seat post to pack the bike for travel. Back to the PNWet yet again.

mine started life with campi nuovo record (classic) derailleurs and shifters, but an assortment of other parts. I think it had a campi crank too, but the brakes were some other kinda crap that I upgraded. sewup wheels on Atom hubs (JUNK!). In 75, the jap stuff hadn't really shown up yet on higher end road bikes, that happened pretty fast over the next couple years with suntour's derailleur being much better at handling wide gear ranges.

that should be a little easier. at least I don't care about my seatpost, I want it gone, so I can get as brutal on it as I dare. ugh, just checked, its a steel seatpost (and an aluminum frame). which expands faster when its heated, steel or aluminum ?

Mine was late 80's

And my stuck seat post is Campy SR, so I care a bit about recovering it. The bike it is stuck in is my old team bike. Treviso Itallia, Pinarello so I am proceeding with caution. Don't want to buy the next bike I want quite yet.

Aluminum expands more than steel by about 3X.
Maybe a heat gun on the frame and a block of dry ice on the post?

omg, this is like a disease.

went out at lunch today hitting the local recycled bike shops looking for some 700c wheels and stuff. found another bike instead, its not complete, but it has decent 700c wide rim wheels (rims are labeled 28x1-sumtin, but they had fat 700c tires on them, which I replaced with 700x40's that fit sweet) and the seat post isn't terminally jammed in. guy in used bike shop said it was gonna cost him over $100 to fix up and wouldn't probably sell for more than $150 anyways, so he let me have it as-is for $45, hah.

wanna change out the handlebars. already got a seatpost and new tires on it, and need to put v-brakes (has posts already), rear derailleur, chain on it, I'll probably swap out the cranks too, as it has those cheap riveted triple-rings, and I'm just going to turn it onto a 7-speed. mild bummer, its a threaded on freewheel and not a cassette, but ah well. its notably lighter than my existing fat-tire cruiser, these wheels should roll great. I've got to true up the rear a bit, but its a 36 spoke wheel with heavy stainless spokes, so it should be pretty easy.

http://lh4.ggpht.com/_JS1yca5KB-0/TC...0/IMG_6971.JPG

(chainless, brakeless, etc)

so... this makes TEN bicycles, EEEK. :loco


edit: hah! stuck those bars on a little longer gooseneck (more forward), and since they had one old brake lever on them already, I stuck a junk spare V-brake I had lying around on the front wheel, and shortened the funky chain it had and hooked it up as a midrange fixie, and shit, this is gonna be a good ride when I get it tweaked out. I think I want slightly straighter bars, maybe a little wider, like some modern mtn bike bars, and a lower long gooseneck (the one I had lying around was kinda high), and it will be perfect. a pseudo-cruiser that can book across the flatlands, and still climb a hill if I have to. heck, I might just keep the 3-speed front, since the 7-speed freewheel cluster on this wheel isn't nearly as high range as I'd like for a 7-spd.

I do believe its a 1999 Diamondback, originally this cheap thing

if thats correct, the cluster is a 13-28, and the front is a 28/38/48

Well, if you need to ditch a few, we can help.

The frame looks different. No angle with the top bar and wheel stay, or whatever the top bars to the rear axle are called.

I think Pilot's right, that isn't bike #10. The 2001 or 2002 look more like your bike than the 1999 does. Gratz on the sweet score!

Seat Post Success

this is a XS, 15" :deal

the parts that are still on it match the 1999. even has Z chain. has a sunrace 13-28 7-speed freewheel. shimano branded cheep triple-crank. etc.

its been fun riding around my driveway as a fixie, in a 38-18 kinda gear (not sure what rear I shortened the chain to, but one bigger needed a half link, so I put it in 4 out of 7). even kinda like the bars after playing with them and two different stems I had kicking around, but I think I want a lower more forward stem with a straighter bar. I even flipped the bars over to be track style, hahahaha, since there's only one brake lever on them right now, was easy. slapped some oury fat soft grips on there.

the michelin 'city' 700x40's I got ride sweet. I need to fix a spoke and true the back wheel. :-/

its got fender and rack inserts on the back, and fender mounts on the front.

bunch of Taiwan parts on it, the bearings feel decent quality, but the back axle needs tightening a hair. threaded headset looks pretty heavy duty, too.

the rims say 28x1-5/8", and some odd taiwan brand. the sunrace 7-speed freewheel is heavy :(

btw, I do believe I'm swearing off gumwalls. the tires that were on this bike had plenty of tread, but the gumwalls were totally rotted out and sidewalls were frayed and splitting in places.

That seat looks anything but comfortable, but I test rode a Specialized Hard Rock yesterday, and it actually felt pretty good.

I did five miles this morning and the Cloud 9 seat I have wasn't feeling too good. The more I ride, the more I realize that seat should be on a tricycle at a trailer park in Texas.

Got a rack for my wife's bike a few weeks ago.

So the other day I made this block to rest things on with so extra hooks for strapping.

Just gotta figure out what color to stain/seal it.

Perfect, you made her a cutting board. Does she park it in the kitchen?
