Shimano 600 Front Derailleur

Luckily because I had pulled out all those parts this weekend, I knew I had an old Shimano 600 derailleur that fit. It was the original to the bike, but it was super rusty and grimey. 30 mins with a wire brush and steel wool later and I had this. It's late when I took the pic but it's shiny and surprisingly works perfect with the 10spd drivetrain.
Those Shimano FD-6207 front derailleurs are my favorites when I'm building a Shimano or frankenbike. I use them with 5-6-7-8 speed rear cogs. They shift crisply and the cages are long enough to handle many triple setups.

The cages are also wide enough that I rarely have to trim the FD after a rear shift.



Speaking of "tried to kill me", I had my new Ed Litton out for a short maiden voyage yesterday. About 4 1/2 mile in, after fine tuning the seat height and angle. I reduced the front tire preasure from 90 psi to 85 psi and every was perfectly dialed in with a beautiful ride and handling.

I was doing a slow, sharp left hand turn when I felt my left pedal strike... next thing I was doing a face plant!

Sidewall blowout on a NOS sewup!

I'll survive but the brand new black brake levers are trashed!

THINGS TO DO IMMEDIATELY AFTER A FALL:

1. Look around and make sure no one saw you take a spill - to preclude embarrassment.

2. Check out the bike for damage.

3. Check out yourself for injury.

Bummer about the spill, but I had to laugh at that last part. I did those exact three steps today after some railroad tracks put me down.
Everybody saw me!
The bike is unscathed.
I may have cracked a rib.

It was still a great ride.

I hear you, I have permanent scarring on my right hand from a terrible fall years ago. It's damn scary when it happens while you are standing and pedaling.

I am amazed how well that derailleur works. That is 10spd Shimano drivetrain with a SRAM Apex cranks that are compact. It shouldn't work but does perfectly. That is something I love about Shimano stuff, that cross compatibility is great.

I'm on a roll with bike fixing too. Reused some bar tape on my Jamis Aurora with the weird Denham bars.

Put together a new custom 9 speed cassette for the Pelizzoli today: 12-14-16-17-18-19-21-24-28. Paired with the 50/34 compact 6206 crankset, makes for a really nice 16-19 mph pace on flats and rollers, with a couple small ones on the bottom for downhills and a couple bigger ones on the top for more troublesome hills.

Today I finished a project that had been in the attic for a few years, a 1988 Concorde Gavina from 1988. Total respray and rechromed, a rare Campagnolo Chorus Graphite groupset and lots of other NOS bits and pieces.

It's super heavy duty and super heavy Merziac said it was originally designed for use on motorcycle wheels but I have seen old pics of them used in some Japanese factories to build wheels..it is marked TANAKA tools Japan so?
Anyway, I am happy to have this piece of history even with the repair.
Best, Ben

before the washdown.
I think you are right that your stand was for motorcycle wheels, it looks bigger than the HTK I restored some yrs back.

Wow, yours looks great....I did some additional research and found this on the web...so it must have been used to do both types of wheels.

Base's are slightly different

The Shimano external BB (BB-4600) on my commuter bike has developed the dreaded knockin' and a rockin' so it's all change and I'm going to downgrade it from Tiagra 10-speed to Tourney 7-speed. The strip down went OK this morning and I've slapped in a really smooth UN-55 square taper BB that came out of the parts box as did a Chinese 'Litepro' 48/38 chainset. I already have the Tourney shifters and mechs and will re-use the Shimano BR-R451 57mm drop brakes but with new pads as I was just getting down to the metal on the rear. Apart from the pads ($23 inc. postage) I've had to purchase a new cassette and have gone for a ridiculously cheap 8-speed SRAM 12-23 ($9 inc. postage) so that I avoid a spacer and have a built-in spoke protector (albeit a heavy one). Everything else, including the chain and bartape is already on the shelf.

This is my only bike with fenders so thankfully it's dry here for 4-5 days so a mid-week wrenching session when my parts arrive should see my commuter back on the road before my next shift (Thursday).

Edit: Apologies folks for not noticing that this thread is within C&V.

Man's. Is it other than an A08? I'm thinking something else. Thoughts?
I'm addressing things left undone, hubs, headset, rear derailleur pivot tension, etc. Also truing and a bad tube.

I haven't evaluated this yet. They complained of little things not quite right. Mostly, their friend made nice choices: hammered fenders and VO saddles...

'Honest Fixie/SS and a "wet-bike" trainer

I have been riding singlespeeds as my urban steed for a few years, and have always had to fuss with the rear wheel alignment, etc...I finally started hunting for a bonafide track frame (an older KHS/Ritchey frame originally commissioned by <SanFranCyclo.com> and transferred my SS setup to it...so much nicer!! (pics below)

Also working on getting a meaningful 'wet bike' together that will still be fun to train on in the winter. Have an older Miyata 710 (that was also my most recent SS) and bought a middle-aged bike with a VGC Shimano 105 group and some decent Cane Creek Crono wheels (after truing). Scored some SKS P35 fenders on clearance from REI and ready to start building. The 710 has nice clearance for 28mm tires and full mounting bosses (unlike my main roadie Miyata Team Pro). I'm tired of hosing off my MTP...hope I finish it before the rain stops!!

Here are the SS/Fixie pics (question to all...is it worth buying/making a single stem spacer to replace the 3 that I had lying about?

23 pounds before lights and U-Lock. This will get a new saddle (WTB CroMoly Volt) in a few days. The Specialized is shot


Really dig the function and look of the Suntour Superbe brakes. Have had these in storage for >> a decade!

I cleaned up my '74 Paramount after several months of having not ridden it after a wet ride home sometime near the end of last year. The tan wall Soma tires I did have on it were dirty, so I opted to just swap on freshly cleaned Compass tires after getting the wheels back to their previously shiny state. Both sets of tires I bought used for cheap, and both were very dirty and I employed some Meguiar's car wash soap and a sponge/brillo pad with warm water in the tub to clean them up.

The front wheel needed truing and a decent upping of spoke tension. The rear didn't need much truing at all, but some spoke tension increase was dialed in as it was also low. The real discovery, which was a bummer, was small longitudinal stress cracks on the rear rim by the spoke holes/eyelets--three or four of them have it. I have no idea how long they've been like that, but suffice it to say, a solution must be reached. I have a few ideas I'm entertaining:

1) Find and buy a used/NOS/whatever polished Mavic MA2 rim, 700C, green/yellow label (late '80s/early '90s), 32 hole
2) Replace both rims with Pacenti Brevets
3) Replace both rims (and likely spokes?) with H + Son TB14s (polished)

Depending on who you ask (or look up), MA2's have an ERD of 612 or 613mm (Zinn says 613mm). The Brevets have an ERD of 611mm and the TB14's have an ERD of 610mm.

Part of me thinks I could get away with just swapping the Brevets without changing the spokes as the ERD is so close. I'd use new brass nipples of course. I'll have to check to see how deep the spokes go into the nipples' threading. That will tell me a lot right away.

Why not change spokes, too? Well, for one, it's another expense and two, the current spokes are externally butted and we all know: match-match-match. And on the flagship? I think we know the answer. The 7400 hubs are still in great shape and spin forever. And given everything, my most economical option is likely to be finding another MA2 rim in great shape and simply changing it over. This 7400 hub/double-butted spokes/polished MA2 wheelset is my favorite, is only bestowed upon special bikes, and at 30 years old, owes nobody anything as it has held up extremely well over time. I've owned them for three or four years and they remain solid. I won't be riding bikes for a little bit here for a number of reasons, so there's no urgency per se. I'm currently deciding on some fenders for it as I seek to solidify its all-around capability as I continue and plan the winnowing of the fleet.

Anyway, here's a picture!
