Got it built up almost ready to ride...

Chain is a little too tight with the 48 tooth Biopace ring and 18 tooth sprocket, think a half link should do the trick :)
I'm waiting on some gold wheel Q/R's arriving, and may swap to a white saddle at some point.
Wheels are borrowed from my other bike, I have some Specialized GX26 rims to build some wheels with at some point.
I will be fitting lights & mudguards as this bike will be used for my short ride to work most days :)

Does S/S work with biopace and no tensioner?

It should do, all my research suggests it will be just fine, as there is always the same amount of chainring & teeth in contact with the chain (it sounds odd, but is true!).

Still, will wait for a half-link to arrive and that will hopefully give the right chain tension, if not then I'll run a chain tensioner, although I'd prefer not to, if only for the visual effect.

Finally got this bike finished (well, pretty much!), only things that will change will be a swap to a San Marco Regal saddle at some point (White/gold rivets) and a wheel change to Specialized GX26 rims with (probably) XT-M730 hubs when I get around to building them...

Chain tension is now sorted, I bit the bullet and filed out the rear dropouts a few millimetres, which was just enough to provide decent chain tension without the need for a tensioner.
I also changed the Shimano Biopace chainring for an SR one as the SR has what look to be higher profile teeth which should be better for keeping the chain on.
Mudguards and lights have been added as I'll be using this bike to/from work.
Given the bike a couple of brief test rides and so far so good, chainline and tension seem ok, have to laugh at myself though as I find my right thumb still thinks that there is a shifter there :lol:

For those interested in the Suntour rollercam brakes here's a few pics which show the difference between the brake which came with the bike (maybe a Suntour XC Sport 7000?) and the XCD4050 which replaced it...

Image

The biggest difference is the old brake (left) had internal springs, one of which was slightly bent out of shape and made setting it up a nightmare, the XCD4050 has an external spring between the two brake arms and setup was a doddle by comparison.

Here the old cam is laid on top of the new cam, and the cam profile is pretty much the same.

The Specialized GX26 rims (as per original spec) awaiting building up into wheels...

I'm very happy with how this bike turned out, when I look at the pics of the frame as I bought it and what it looks like now I can hardly believe it's the same frame! It's nice to know that I'm riding about on a 25 year old mountainbike :shock: and that it will continue to be ridden for many more years to come...
