Thanks Brucey, maybe next time ( shuddering at the thought of another rebuild ).

I have to admit to some light squirts of X100 [semi-fluid grease] post-rebuild.

The X100 that I had applied sporadically, pre-rebuild, was clearly present and functioning - if a bit mucky.

Hopefully not too destructive . . . . . ..

This was written by me in 2017 on the previous page.

I've just fitted a brand new Campag Veloce 10sp chain on Moulton. The previous one was shot. I've had the new one some years.
The one on Mercian is ok for a while yet, but in an idle moment the other day, I was looking online to buy a replacement Veloce 10sp.

Could I find one at a reasonable price?
Could I find one at all?

None reasonable, and few available .................... so this makes my statement above rather prophetic methinks.
Most of the online shops had them in the past, and now few have at all.

Ho hum. . . . after the recent rebuild with G-spring replacement, the right-hand Ergopower is performing badly.
It was unusually stiff on paddle action immediately after the rebuild - but felt normal on the thumb trigger action.
Now, after only 60 miles or so the rear derailleur is hunting across #6-7-8 sprockets.
I will investigate in due course.

I think I will initiate the contingency plan in any case. If I can still get hold of appropriate Tiagra 4700s shifters. ( Hopefully a straight swap for the RH Ergopower. )
I fear that Shimano might have placed some gotchas in the way since Brucey's suggestion below . . . e.g different versions of the 4700 with maybe different cable pulls .
PS. I'm hoping to leave the Campag long-arm derailleur and Campag compatible Miche cassette on the back.

e.g.
RH-only : Shimano Tiagra ST-4700 Schaltbremshebel Shifter 10-Fach Grau Neu https://ebay.us/yhqwEb via @eBay_UK
Pair : Shimano Tiagra ST-4700 / ST-4703 Schaltbremshebel Shifter Set 3 x10-Fach NEU! https://ebay.us/wZC8Up via @eBay_UK

? Probably need a new Shimano Front derailleur if I get the LH lever too ?

Brucey wrote: . . . . FWIW (apologies if this sounds like heresy) the recent Shimano Tiagra 4700 10s STIs are worth a look too; I think that they are almost plug and play with campag for the rear shift (you might need a very small tweak), but that you will need to do something cunning with the front shift. For a road double you have two main choices here;

1) use the shimano mech (FD4700 or an 11s shimano front mech) with ST-4700 shifters and a double chainset or
2) use the ST-4703 triple shifter and a tweak to the extant campag double front mech (to adjust the arm length)

Provided you don't need to use the trim setting on the small chainring you will be fine, but if you do, some careful setup will be required. The shimano triple mech FD-4703 is almost the same shift ratio as the campag double, and is also not far away from the shift ratio of some older shimano doubles, too.

I have not tried the ST-4700 shifter/campag mech and cassette combination but a while ago I did look at the reverse, i.e. 10s ergo with shimano 4700 (or 11s) RD and 10s cassette. IIRC it was close to working perfectly as was, (and may have been 'good enough' for some folk), but the cassette spacing needed a tweak to make it a perfect match, in the form of adding shims between a few of the larger sprockets.

This suggests that with the reverse combination the sprockets may need to be respaced in places so as to make them closer to one another. It may work well enough without this, but I think it can be done if necessary; perhaps by sanding some of the spacers down and using 11s chain.

I think that some of the campag specialists still offer to repair 10s ergos, even if they don't offer to sell you the bits to do it yourself. This might be a cheaper/better option than buying new shifters that won't necessarily work perfectly without further messing about.

cheers

Thanks Brucey. That has stopped me from blundering off in the wrong direction in a fit of frustration.

A pause for thought. EDIT . . . . . . . .

, , , , And some investigation by isolating the various components . . . . .

I jumped to the wrong conclusion :-
- The Ergopower mech is OK
- The rear derailleur is OK
- some resistance in the cable leading to the replacement of the loop of rear outer cable ( entering the derailleur ).

It feels better now, but some road-testing should confirm the fix undertaken or lead to the next diagnostic step.

Mercian are well known for having an excellent ergo repair service - they serviced 9 speed Chorus for me.

Hopefully, the expert still works there ( or he’s trained an apprentice) as he was part retired and did a few days a week as the repair was about 5 years ago...

The issue is the availability on new parts.
The writing is on the wall for my 2006 Chorus Ergos as the RH one is showing signs of wear.
You can get springs and such, but the main ratchet isn't available anywhere, and it's the main ratchet in mine that is worn.
It still works ok, and will do for some few years yet - perhaps more as I'm not riding as much as I did - so I'm not worried as yet. When it does pack in, the Ergo may as well go in the recycling.

as I mentioned above, some repairers have stock of the index wheel part which they will use for repairs, but they won't sell separately as a spare part.

cheers
