I've got two more bike projects on the burners now.
First is my 1981 Miyata 610 which is in the stand and going to get a full overhaul. This bike will be worked on in stages while I use it to commute in good weather. After overhauling the BB, I'll install the "new" (to me) Suntour Superbe idiosyncratic crankset with different length arms to make up for my leg length discrepancy. I used to train and race using a pair of Sidi Genius shoes with a thick nylon spacer that I hand-fit to be perfect for me. The spacer was a corner of an old cutting board that I got from my local second-hand store for $1.
Anyway, I don't need to be riding around in racing shoes anymore. If I get a hankering to use the clipless pedals, I'll just change a crankarm and stick on the other pedals. For regular duty, the Miyata will be sporting a set of Suntour Superbe pedals as well.
It will get a new chain and I'm going to re-gear my freewheel since my chainrings are going from 53/38 to 51/42. I don't need to be going super fast so my small tooth will be 14 and the large I think a 26, maybe 28. The rear derailleur is a Cyclone GT, so it can handle 32 for "alpine" gearing if I want.
I have a decent stash of Suntour New Winner freewheels and spacers. These freewheels were approved by Suntour (and recommended by most builders) for tandem use, so I'll probably never kill them all. I once blew up a Regina Oro 6 speed freewheel right outside Manayunk on my way to Valley Forge on the Schuylkill path. I digress...
So the Miyata will get a new drivetrain and new pedals at first, I'll ride during the daylight hours, but eventually I'll build a new wheelset with a dynamo hub to push power to a set of lights. I've gotten spoiled by my touring Univega with a SON Edelux II headlight and a B&M taillight, so I want a similar setup on my Miyata. Most of my other bikes have dynamo front hubs and B&M lights, which I feel are indispensable now. A huge safety upgrade for riding in the city.
The other project hasn't arrived yet but is over at my friend's house still. It's the 1992 (possibly 1991) Breezer Lightning.
I'm sticking a set of Magura hydraulic rim brakes on it and at first I'll be rolling on a set of wheels I used to commute on; front is a Suntour XC Comp hub laced to a WTB Maverick rim, rear is a Sturmey Archer Kickback (freewheel) S2 hub laced to a matching rim. Shifting will be handled by the greatest shifters ever made, the Shimano XTII 7 speed top-mount thumbshifters.
What I'll build up for wheels to use full-time is in question. I've got the hankering to be different and use a set of NOS Suntour XC Pro hubs with freewheel threading, then just use one of my New Winner freewheels. It was the Suntour Ultra spaced 7 speed that set the 5mm spacing for the entire index shifting industry, so a 6 or 7 speed Ultra spaced freewheel will shift perfectly with my XT shifters. The key to indexing is to use the same brand for shifter and rear derailleur, so the cable pull rate is the same. Once mixing and matching start to happen, things get weird, but can be made to work.
Anyway, the only risk of using a freewheel on a mountain bike is the drive side bearing is well inboard and impacts can bend axles. Granted, I've never bent an axle using a compact New Winner. I did bend a Campagnolo Record axle when running a Sachs 8 speed freewheel, but that was crazy. a 135mm OLD spaced freewheel hub and 8 speed cluster is just asking for trouble. I think I can stick with 120 - 126mm OLD and run a 6 speed in the rear.
If I don't do that, I'll go with Shimano, but I'll have to purchase a set of used hubs, which I don't really want to do. I don't like lacing up hubs a second or third or fourth time, even though I know I'll probably not break them. There's just that itch in the back of my mind knowing that a previously tensioned spoke created a stress riser for every single spoke and the hub flange is weaker, in theory. Anyway, that's how I'm thinking for the scheme of the Breezer.
I also have this wild notion of making it a single-speed with a flip-flop hub and using it to get into technical trials riding....
