Piaggio Bianchi Sport SS

Postby QuangVuong » Thu Jul 03, 2014 9:24 pm

I mentioned this bike in another thread, a $50 Bianchi. I spotted this on Gumtree, and Ill give a big thanks to rogerrabbit for picking it up for me. Saw a B panto on the crown, and Bianchi on the rear dropout as well as parts of the Golden Arrow group, and I just had to get it.

I believe this is a Sport SS model as from the remnants of the top tube sticker. This is a Japanese made Bianchi, and what should be the 2nd highest model in the Sport line up, coming in behind the Sport SX model. And according to Sheldon Brown,
Sheldon Brown wrote:Bianchi
While Bianchi is best known as an Italian brand, it was having bicycles built in Japan to its specifications for several years in the late 1980s. These were particularly nice bikes, with better workmanship than the Italian models.

Image

Serial number is LS328488. Dunno what it means, but I do know its a 1983 bike(from component dates).
Image

B panto and Ishiwata Magny tubing sticker. Nothing special about the tubing.
Image

Discoloured(from metal pump clip corrosion?) seat tube Ishiwata sticker that says 'Guaranteed built with MAGNY Ishiwata. Double butted tubes, fork, & stays. This one also has Piaggio stickers, from the time when Piaggio owned Bianchi, which should be from 1980-86.
Image

Kusuki Winpista bars(which were more comfy than Id though. I only use the Sakae Anatomic bars) with an odd 0.833 sized Sakae Custom stem. This stem actually is too skinny for the steerer. A standard 22.2 fits in perfectly, and Im not sure how the stem ever got put on this bike in the first place. Stem will be replaced with another Custom stem seeing that Ive got one in 22.2.
Image

Seems like this bike was sold at some Bike n Hike store in California. Explains why the brakes were set up backwards to the Aussie set up.
Image

Cool looking Sakae CR cranks with Sakae SP-153 pedals, and the Golden Arrow FD.
Image

More Golden Arrow, the shifters. Friction shifting wasnt as hard as I thought itll be. Worked well enough for the hills around the North Sydney/Manly area.
Image

RD and a hint of the Bianchi dropout
Image

Non Golden Arrow brakes, but they work amazingly well, even with the original pads.
Image

Anyway, the bike has been pulled apart, ready for cleaning and polishing. The bike will mainly remain the same, other than a correct fitting stem, different seat post and saddle, possibly a new headset, and the 27' Arayas will be replaced with spare 700c Open 4 CDs, as well as mudguards to fill in the empty space. This is one of the 6 bikes Im currently building, so it might take some time, but I should get it done by the end of the month, hopefully.

It looks like a bike with a ton of potential. Well spotted. It will be nice to see it once you've performed your magic on it.

I quite like those Sakae 'swept spider' cranks, I've seen a couple of them floating around. Something a little different.

Are they 110mm BCD?

Really nice!

Quang, the trick with friction shifters is to fiddle with the tension on the RD lever until it's just tight enough to hold the lever against the cable spring tension. Then the shifts can be 'flick switch' quick once you get the hang of the 'just right' shifting distance on the lever.

Got the group cleaned and polished over the past few days. Yes, these cranks are 110 BCD and any 110 rings will fit it.
Image

And pulled off the fork. Found out its JIS, and the only JIS headset I've got is a 6400 one. I really don't like the original headset, so I'll prob just run the 6400 headset. Check out the nice paint too.
Image

And then test fitted a mud guard and a 700c wheel. Looks good, so the original hubs will be unlaced and then built to some old Open 4 CDs. As this is my only bike with eyelets, is it supposed to be threaded or not? The left eyelet is threaded, but the right eyelet is just a hole. I didnt notice if the rear ones were threaded or not.

Nice work QV, you always do a meticulous strip down, clean and rebuild.

Just curious about the big ring not being interchangeable. I've got a triple set of these cranks on a commuting bike with a 50t big ring. I've swapped the worn inner rings, but haven't needed to with the outer ring. Are you just referring to cosmetics or is there something there that makes other big rings not fit? It would probably look a bit odd with a normal pattern ring I admit.

Ends of the arms on the crank spider are angled, never seen that before.

I thought the mounts still form a 110BCD circle though (even though optically it doesn't look circle shaped). Probably a moot point, I could go check myself but it's dark, cold and wet outside between my house and shed.

Ah, looks like I was wrong. Standard 110 rings will fit. It's also cold, dark, and almost full moon, but I went out and tested it.

Thanks, you've saved me a trip outside :lol:. It might be dark & near full moon in Sydney (supermoon on Saturday), but I'd be surprised if it was 'cold' (my partner is in Sydney at the moment and has commented on how mild it is).

Oh, nice purchase by the way.

Hubs polished, and wheels are being built up. Front is done, and rear will be built tomorrow. This rebuilt is nearing completion.

Looking great, those Golden Arrow components come up really nicely with a polish - do you have any particular plans for this one?

I bought it because it was cheap, and will be a wet weather sort of bike.

Frame polished up. The paint came up well.
Image

Anyway, mostly together now. There hasn't been any adjustments yet, so hoods,bars, etc looks a bit off. Upgraded with a JIS 6400 headset, cartridge BB, 700c Mavic Open 4CD rims, and mudguards.

In 2 and a half month's time, I finally got around to putting on a chain and wrapping the bars. Took it for a 20km ride, but found out that the rear wheel is noticably oval. Oh well, Ill have to find another 36h Open 4 CD to rebuildto the hub.
Image

Hoods are dry, but I dont see how people manage to brake from the hoods with these old single pivots.
Image

Shiny shifters. Friction shifting aint all that bad, just need to hear the chain clunk over and then I know that it has shifted.
Image

Didnt know that these non parallelogram RDs take a lot of chain up. This is a full chain with no links removed.
Image

And shiny hubs
Image

A very big transformation from the day I picked it up. Cleaned up really well.

Mind if I ask the brand of those mudguards?

Hi, You have a very nice bike. I just got one yesterday but only the frame set. Pretty much complete minus the wheelset. I have a question regarding the width of rear hub spacing. Thanks.
