Made my own b-screw for my Tiagra RD 4400-GS. The flat step on my frame's derailleur hanger was too far around for the stock b-screw to catch, so I went to the hardware store for a longer M4 screw, with a wider head, plus two nuts for it. I screwed one nut up tight against the new screw head, then put the screw in the wrong way, and snugged the other nut up against the the derailleur tab, right where the old b-screw head would have been.

Like this:



b-screw solution

Now the upper roller pulley is kept out of the cogs, otherwise the derailleur would have been unusable on this frame.

@52telecaster, you did a lot of clever things there. Can you give close-ups or an explanation of your headlight mount?

I've been wrenching on this one for a while now. 1983 Pro Miyata, most significant non-original items were brake calipers, seat and post. Getting pretty close now, took a short spin in the road today to check the basics.

Test fitted the new wheels to see how they match colour wise and for clearance. I need not have worried since it turns out they run a little narrower than the Soma Supple Vitesse EX that are on there now.

Finally got around to swapping out the used Dura Ace rings I had built the Krapf bike up with. Had a decision to make as I had bought Swiss Cross dustcovers for the crank also. It was either put on new and proper Suntour rings with silver chain ring bolts and the Swiss cross bits or stick to the red anodized dust cover and use red anodized steel chain ring bolts. Here's my decision.



The Swiss dust covers are a completely different looking red.

Love this derailleur. They look great, they work great. I don't even miss indexing at all and this is the derailleur (in combination with LD-4850) that convinced me to switch to friction. Now you just need Superbe brakes and brake levers

Well, I was keeping it as original as possible..
The AGC300 brake calipers had unobtainium pads (I like Kool Stop better anyway), so those had to go. The tire clearance issue is pretty tough on these too. I had used the Shimano 410 dual pivot calipers before on a couple of bikes and knew they would clear the tires well enough, so that's the way I'm going for now. The AGC levers almost didn't make it until I finally got good hoods from down under.
The Suntour Symmetric shifters are a pretty nice unit, auto trimming the FD with RD shifting.
I'm going to ride it a bit on the 700x23 clinchers and then decide whether to go tubular for a better ride.
I don't know whether I'll eventually try to go more Superbe on this or not.

I finally built the VO Randonneur I bought last summer the most notable thing about the build where the brake calipers those Grand Cru brakes while are my style and they stop really well I don't think I'd used them on anything vintage even with the nice amount of reach.

Swapped out the drops on my Pug TH8 tandem for upright bars- looking forward to weather warm enough that I can convince the S.O. to stoke to the coffee shop.....

Suntour Superbe calipers have plenty of clearance. I use 700x25c tyres mostly with the frame I have them on, but it looks to me like they would have enough room in there for 700x28c. I'm talking about 4700 version, not sure about 4000. Dia Compe equivalent (to match the levers) would be Royal Gran Compe 500.

My wife commented once that she thought she would like us to have a tandem. I nixed the idea because I figured that after 40 years that would be the straw break the camel's back. But I think I would risk the ensuing argument and ultimate divorce to try it on a tandem this nice.

TBH, I think the looks/attention the bike gets is more than half the reason she humors me by agreeing to ride! But it most definitely is an exercise in 'radical communication' and relationship testing!

Thanks for the info. I think the 4700 is probably too long reach for the Pro Miyata.

Last night I decided I just had to ream the seat tube on gitane three speed (tour de france). After reaming maybe 40 bikes in my life, for the first time I dropped the reamer into the seat tube and it stuck. An hour later with bb removed and copious bouncing the frame upside down, it came out. Why you ask am I this stupid? Because I just had to go from 26.4 to 26.6 so I could use a campy seat post. On the upside its kind of like cross training to work hard on the bike instead of riding it.

I got wrenched on yesterday.

Five screws and a plate. I have no idea how many stitches I got. I'm stuck in this soft cast for two weeks, then six to eight weeks in either a hard cast or back in the boot. With Mrs.Bikamper's attitude towards me these past couple of weeks, I may sell our tandem that she's only ridden once.

I'm with ya on this, Campy 2 bolt FTW and Brooks, no C+V is complete or correct without them IMO.

Took advantage of the good weather....before the rain started. Almost got this wrecked Lejune stripped, I forgot a headset cup apparently and got hung up on the fixed cup. The crankset was a cottered Sugino and the BB spindle was English, I think TDC? I think the cups are also TDC and need a 34mm wrench, which I don't have. I also haven't figured out which way it's threaded.

I honestly didn't know there was such a thing. I've always used a wheel cylinder hone.
