That's a 28. I haven't needed anything smaller so far. The crank and FD are from the Suntour X1 MTB group. So, If I need a tiny granny, the FD will shift it.

Liking the geometry on this, almost a track feel to it

I should have known, I don't normally need anything smaller either since I avoid hills like the plague as much as I can.

I had a 28-36 granny the first time I rode Crater Lake and thought I was in pretty good shape but still had to walk a half mile on the big hill. The next time I went I had 24-36 and made it the whole way, still have it on that bike and use it very little even with 32 out back for now.

Your campy RD can shift to a 24-32? What are your other chainrings? I thought a long cage maxed out at 39T capacity and a 29 or 30 big cog on back?

1994 Miyata 916 Shimano 105 Nice bike.

With some more changes… this thing is a blast on mountain bike trails.

I think I've posted these builds in other threads, but never here. Both have been in use of late and both feature steep HT/ST angles (74.5x73.5-degrees for the 1989 Klein Performance, and 75x77-degrees(!) for the 1973/4 PX10LE.

The Klein has a 10s Shimano cassette that I fitted to the original 126mm 7s freehub, using a (longer) SRAM 11t lockring nested into the smallest 12t cog.

The Peugeot has a 124mm-spaced FW hub crammed into the frame's 121mm spacing, with a custom 7s D-A freewheel having five largest HG cogs from a 1990's freewheel, and which works quite well with 8s Ergolevers and RD (after I slipped a plastic noodle into the bb cable guide).

That is right up my alley. Thank you for posting it here!

Greetings all. Newbie here. Great thread - I only have one more year to go.

I have a question I think is relevant to all the rebuild experts here. I'm building up a 1984 Miyata 710, and right now I’m riding it with a 7-speed freewheel, R2000 derailleurs and a Shimano 52/42 1055 crankset and BB. It’s time to spread the drops and put some more cogs in the back, but it’s not clear to me what chains would be compatible with the A550. Should I stick with 8-spd, or can it handle more?

Thanks for your help.

Welcome Prunesquallor !
Great question! The key is matching the chain to the cassette. So, 9-speed chain if using a 9-speed cassette to ensure the best rear shifting. I've found it doesn't matter much with a different "speed" chain than the crank. I currently run a 9-speed chain with a 11-speed crankset on my Lemond, and a 10-speed chain with a 9-speed crank on my townie, both with no front-shifting issues.

Thanks for the reply. I was considering running a 10-spd cassette and chain with that 8-spd crankset. I’ve seen concern expressed online about the possibility of the narrower chain dropping between the rings.

Do you know if this bike originally came with canti studs or was that a later addition?

My unknown year motorbecane nomade with 10speed Ultegra groupset. Waiting on clamp for front derailleur. Currently has 28mm gatorskins but have 35 studded for winter.

This ones done.

This is an 80s Alain Michel 700c rando frame with Dura Ace 7800. The rear der is Ultegra.

That bike looks really nice, super slack angles too by the looks. Those mudguards are nice, what are they?

Nice 👍.
Which carbon bars are you using? 26mm or 25.4mm ?

Flatforkcrown

some 26mm kestrel bars I picked up along with a 3ttt record stem for $20 at the co-op

I have two Motobecane bikes from the 1970-80s. One, a Grand Record is tricked out with only Campagnolo equipment. Another, a Super Mirage is in the works to be upgraded as a commuter/hybrid. The frame is in good shape and strait but I think it was designed for 700C wheels. The wheels that I have for it are 27 1/4 and I only have a set of Campagnolo brakes which do not reach the rims adequately. Any suggestions as to what model of Campy brakes would fit this situation? Thanks in advance.

@sbrudno - the usual solution is to find a drop bolt for exactly that challenge.

It appears that people don't visit every page, I don't. Repeating images is likely and maybe acceptable. It is almost like the inverse of tagging pictures, instead we tag posts with pictures!

I have two that meet this threads description.
the first is the newest, i think, a 1989 Pinarello Montello. It was originally built as a 8v 740x bike. Always gravitating toward Campagnolo, in spite of others performance assessments, the Italian frame demanded Campagnolo components. Yes it was index downshifting with the DA but this conversion took it to Ergos.
It is currently still 8v DA sprocket set with Wheels MFG spacers but with Racing T RD Record FD, Racing T chain set, and the key element, Gen 1 Ergo. A Campagnolo wheel set is waiting in the wings with I believe a Chorus front hub and a Record rear. The Rims are also Campagnolo Omega Strada Hardox in the aero configuration. The replacement rear wheel had a 8v freehub but was replaced with a TI freehub and a 9V cassette. A broken Gen II rh 9V Record Ergo was purchased and the requisite parts replacing the 10V parts in a another Gen II 10v Ergo. The swap is in the wind at the moment as the truing of the rear wheel is not complete. Axle spacing is done so it will fit. The 9V willl provide a 26t at the bottom to replace the DA 23t. The need for the third ring may dissolve. The 12t won't be missed! Strangely, the change from 53 to 52 is noticeable.

The second bike is one many may recognize as the 1988 De Rosa Professional with all 10v Record parts. It is a mix of 10V parts but given this is a departure from 1988 frame set era, it fits here. I checked today and the Ride with GPS says I only have 98 miles on it. It too has gone through a number of component changes, driven by aesthetics. This is the most recent picture which reflects its current configuration, black post and stem. One of the reasons I like the De Rosa is the 25t sprocket in the back. Until the triple was applied to the Pin, the DR was easier on the hills.

Neat build! What bag and rack are on this?

pstake 

THanks, JJ, believe the angles are both 72. I'd have to refresh my memory. The fenders are Rene Herse/Honjo. The rack and bag are custom from Tim Tas Rex, and designed to measure in order to fit and work well with the stis. I cant speak highly enough. The bag is also very light which was a theme with this build. Bars and seatpost are carbon. Wheels are Mavic Ksyrium with orange accents on the hubs. Usually it's setup tubeless but I've had trouble converting these wheels. It's fast and lively to ride and handles very well at speed, even with the bag loaded. I'm very curious about the conversation Alain had with the customer who ordered this bike. Randonneur in all ways except with 700c wheels. The rear can only handle a 28, maybe some 30c but it would be close.
