Buying a Bike for its Parts

Late 1980’s Deore thumb shifter with optional friction mode.

Vintage bicycle parts are often hard to come by.  While I have decided not to participate in the current trend of dismantling and re-selling vintage bikes and parts on eBay, sometimes buying a bike for parts is the only way you can acquire what you are looking for.

1989 Bridgestone MB3 – with non-garish 80’s color scheme

So, almost by accident, I purchased a 1989 Bridgestone MB3 in order to harvest the parts I wanted: Deore friction/SIS thumb shifters, Deore derailleurs, and a very unusual lavender anodized Nitto dirt drop style stem and Nitto bar (see below).  I also noted that the bike’s wheelset looked pretty good – Deore hubs, laced with Wheelsmith spokes to a Ritchey Vantage rim.

When the bike arrived, I was a little taken aback by the quality of this frameset:  triple butted Ishiwata oversize tubes, and forged drop outs with eyelets.  These features, combined with the two bottle cage mounts and rear seat stay rack mounts, make for a versatile frame.  The secret is out that lugged steel mountain bike frames make great Portland winter commuters.  I think my 1987 Panasonic MC-7500 is feeling a little threatened right now.  I had planned on selling or donating the MB3 frame, but now I am not so sure.

The Shimano Deore groupset dates to 1989, except for the shifters which have a 1987 date code.  The Nitto bar is not original to the bike, and is in as new condition.  The Ritchey wheelset turned out to be a real bonus.  With a simple hub overhaul and minor truing, this wheelset is as nice as any 26″ example out there.

Appaloosa color scheme

The parts I wanted have exceeded my expectations, with the lavender anodized Nitto stem being the absolute gem in the group.  It is shown pictured above as an idea for the stem on my new Rivendell Appaloosa.  The stem color picks up the brown/purple accent colors in the paint scheme, which is just what I hoped for.

I recently ordered this lovely 2018 Rivendell Appaloosa frame.  It is designed for 650b wheels (a 51 cm frame) and has 135 mm rear spacing.

Why?  I have many wonderful bikes that I thoroughly enjoy riding.  But one thing I have never had since 1999 is a bicycle soul mate – that’s the year I crashed my 1976 Centurion Pro Tour.  Since then, while I have ridden many excellent bikes, I have never found that one bike that speaks to me, a bike that will take me into the next decades of riding, with comfort, competence, and a spiritual connection that is hard to explain.

In 2012 I built a 650b frameset while attending UBI’s frame building class here in Portland.  That experience helped me realize two things:  experienced frame builders have much knowledge and lore that newbies should respect and value. And, many cycling “experts” don’t know a thing about frame geometry, especially as it applies to riders under 5’6″.  One of the (few?) nice things about being an accountant by trade is that math comes naturally to me.  So, understanding the complexity of frame geometry has always been a high priority.

The 650b frame I built back in 2012 is currently being repaired with additional brazing on one of the lug joints that I didn’t do so well at filling with silver the first time out.  When that frame has been sand blasted and painted, I’ll build it up.

Meanwhile, I received shipment of the Rivendell Appaloosa and 650b Velocity wheelset I had ordered earlier this winter.  When the frame arrived I was amazed to see that Rivendell had protected and packaged the frame in a way that only bike geeks can appreciate. As a buyer of bike frames, I have received countless frames shipped with no tubing or drop out protection.  Some eBay sellers simply do not have a clue as to how to properly ship a bike frame, so: Caveat Emptor.

As expected, this bike’s paint scheme is lovely, in fact, extraordinary for this price point.  The fork crown has ornate patterns, with mounting holes on top to accept stays for a front rack.  The Appaloosa head badge is fun and interesting (it’s a Rivendell!), and all the lugs have been filed and well brazed.  For a frameset that costs the consumer a mere $1,300, the value is clearly reflected in these features.  A Rivendell frame is one step away from custom, but inexpensive compared to custom options.

Is this a cargo bike?

Whether you want a kickstand or not – here is the bracket for it

Beefier than any other dropout – and with two threaded eyelets.

Two more eylets on the rear dropouts

3 rack mounts on the seat stays, plus the eyelets on the dropouts.

Silver tubes – butted and cro-mo

One thing to note about Rivendell frames is that they can have a longer wheelbase and longer chainstays than expected.  This Appaloosa has 51 cm chainstays. That means it is in cargo bike territory for its wheelbase.  For this frame (advertised as 51 cm size), I measured the seat tube as 50 cm and the top tube as 55.5 cm.  These measurements differ from the specs shown on Rivendell’s website.  My measurements are center to center.

There are a few condition issues with the frame.  The seat stay cluster was filed very thin, but the upper portion extends outward, and with a little paint loss, is not ideal.  Also the rear canti stud braze-ons are not well executed.  They look unprofessional, but after examination I think they will be safe to ride.  The head badge was not glued evenly to the head tube, as shown above.  Naturally, I am documenting these issues in case anything arises with the performance of the bike.

Because the frame is heavier than other frames that I ride, I expect to replace the FSA headset and the low-end Shimano bottom bracket.  I’ve got lots of interesting vintage options in my parts bin that are lighter weight and probably more likely to last through the ages, as well as provide better performance.  Smaller riders can benefit from weight savings, and I intend to focus on that as I consider options for components.
