Here she is!

8 speed Veloce ergopower and 8 speed Ultegra cassette with 6208 Shimano 600 rear derailer.



I have to install the shiftmate tommorow, but as is - it shifts nicely at least three sprockets

Front derailer of course works flawlessly with ergopower.

Those Ergos look great on that bike Branimir

Thanks for the kind words and sorry for low quality of the photos, it's a silly mobile phone camera!

In the near future, I will overhaul the whole bicycle, that is, probably strip the paint since it's already full of dings and scratches and paint falls off to easily. Will replace the "replacement taiwanese colnago look-a-like fork" with a "replacement taiwanese chrome fork" Unless I find a pantographed fork for 30 euros locally

IMO, that fork looks pretty good! I assume that the drop-outs are forged?

^nice! classy build.

I assume you are riding on roads with gorgeous sea views/beaches/architecture down there?

Two years later, a basketcase is now ready for the canals once the seat is replaced. All Shimano 9 SP 105 except for crank. Was worried if the under BB cable routing would be too much friction for shifting but it all worked out.

Thanks to Gary at Fountain Hill Bikes for the parts.

Hehe, no really, at least not right now, since I live in the continental part of the country, though during the summer I spend some of my free time at the seaside, so riding along the shore and nearby hills/mountains is fun

Btw still not sure about setting up Shiftmate, I got the tension of the cable right, and it shifts precisely through whole 8 sprockets, but I'm not sure about the cable housing length, is it too short or?

This is now in biggest sprocket back, and smallest front, and by this photo it seems the chain is a bit too long? Anyways this is the old chain, I'm putting up a new one tommorow morning

It appears that you won't be able to get the cable set up any better. I'd leave it alone, and only change the set up if it fails to perform correctly.

Speaking of performance... I have a tech question for these retro-refits. Has anyone tried to use the 8 speed shimano shifters with a 7 speed cassette? The spacing between 7 and 8 speed is only .2mm dofferent, so I'm wondering if there is enough "give" to make this work?

I'd like to upgrade to brifters, and I don't want to respace the frame for a 130mm hub... So I'm thinking the easiest (and cheapest) would be to run an 8 speed brifter with my existing 7 speed cassette. If that's not workable, I suppse I could get a 9 speed brifter and run an 8-of-9 cassette... or even a 10 speed brifter and run a 9-of-10 cassette.

8spd Campagnolo uses the same spacing as shimano 7. This would be your best option outside of changing to 130mm.

Thanks!!!

Shimano has come out with a 7 speed Tourney brifter. They look like the old Sora. Tourney A070. I have not used them or seen them in person. Online they sell for $110ish.

I would rather have the Campy.

This gets posted a lot on this forum, but I don't believe it's correct. My understanding that the sprocket/cog pitch for Shimano 7 and 8 is 5.0 and 4.8mm respectively. That's not a great difference and you may be able to make any number of combinations shift well, but it's different so it can't be the same.

Edit: My mistake; I read thirdgenbird's post incorrectly. It is correct that Campagnolo 8 and Shimano 7 both have cog pitch of 5.0mm. My experience with Campagnolo 8 speed Ergos with Campagnolo 8 RD and Shimano 7 speed freewheel was excellent shifting.

Cynikal 

I have interchanges shimano 7 and 8 speed shifters and RD's without any complications. From brifters to thumb shifters. It all seems to work just fine.

anixi

If you use the older Campy 8Brifter/RD the spacing is exactly 5.00, exactly matching the Shimano 7speed. It shouldn't have any issues, as I have used this combination several times. Ad a cog in next to the smallest and you end up with 8 Shimano cogs, no spacer between cassette and hub needed.

ColonelJLloyd 

I'm aware of that. I was referring only to the cog pitch (spacing) saying nothing of particular shifters or derailleurs as that's a whole 'nother can of worms.

anixi

Oh, didn't think of that issue. How much difference is the design of the cog teeth between Shimano, Campy and SRAM? I suggest that they're pretty near identical. That's the only problem mixing shifters and mechs re: shifting performance.

TampaRaleigh

Honestly, I think I'll look for 9 speed Shimano brifters and use an 8-of-9 cassette. Problem solved and probably for a whole lot less than Campagnolo.

ColonelJLloyd 

You are correct; I misread an earlier post and my response only served to muddy the waters. My apologies.

tamaso206

if the shift performance is satisfactory to you, you've probably got it set up correctly. it took me a while to get used to the look of the shorter housing run using j-tek-- i think that may be amplified in your case because the housing stop braze-on appears to be closer to the dropout on your frame than i'm used to seeing.

i think the main issue re getting the housing length correct with the shiftmate is to make sure that the shifmate sits flush with the barrel adjuster of the rear derailleur in all cogs. if the hole where the cable exits the shiftmate isn't flush to the barrel adjuster of the derailleur, you will get variations in cable tension depending on where on the cassette it is sitting. does that make sense?

these small variations in tension might not even make a big difference on an 8speed setup, but i have had to tinker a bit to get it right with my 10speed shimergo.

tamaso206

posted about this already... just thought i'd give an update and provide a photo that does it a bit more justice.



the old single-bolt seatpost failed, so i replaced it with a thomson setback, i love how easy it is to fine-tune the angle. added planetbike mudflaps to my VO fenders-- makes all the difference in the world! no more spray on the feet and grit on the drivetrain is virtually a non-issue, even when doing dirt path riding.

First time I ever heard anyone actually say how well they work. Thanks. Tight bike.
