Aluminum Fender Installation Tips

Installing rigid aluminum fenders is a process that differs more than you would think from the installation of plastic mudguards, whether they be of modern variety or vintage.  In fact, setting up fenders and racks can take more time than ALL of the other steps involved in making a bicycle mechanically sound and rideable, or building up a frame from scratch.

There are only a few resources on the web that will help with this process, and one of them is from the Jitensha shop in San Francisco. The guidance at Jitensha is helpful to anyone setting up aluminum fenders.  While Jitensha’s advice deals specifically with Honjo fenders, it translates across most other aluminum fender installations.

In addition to the other tools you might need (drill, punch, hacksaw or dremel, and file), a deburring tool shown above is also helpful.  You’ll also need stays and a set of fender hardware, plus you’ll need to consume a few bottles of Belgian Ale or Champagne (see below).  Yes, this is a very difficult task.

  

If you are working on a bike with newer dropouts, they may not be designed to allow for the fender stays to clear the wheel axle nut. The eyelets on the dropouts shown above are from my new Rivendell Appaloosa frame.  While these eyelets look robust, and it is nice to have two on the front and the rear, their position is in stark contrast to dropout eyelets on vintage bicycles, as you can see from the example below.

Properly positioned dropout eyelets allow the fender stays to clear the frame, thus making set up of the fenders much easier.  Such eyelets allow the rider to change tire widths without having to replace the stays.  In the case of my new Rivendell, it was necessary to cut the stays to the exact length necessary to accommodate the tire size I’ve chosen for this bike.  That means that if I want to change tire width, I’ll have to install a new set of stays.  That is just one example of the difference between modern plastic fenders and their aluminum counterparts.  Plastic fenders have the stay adjustment at the fender, and not at the dropout.

Recessed brake nut instead of 10 mm lock nut – adds additional length to the daruma bolt

Plenty of room for a large cork spacer.

My Rivendell is the rare bike with HUGE clearances front and rear. I will be using 38 mm tires for my build on this bike frame (which can accept up to 55 mm tires). That means that my fender line is going to need some large spacers (of the Champagne and Belgian Ale cork variety – life is hard!).  Even on a bike with regular clearances the front fender daruma bolt is often too short to provide the length needed for the width of the spacer at the fork crown.  The solution is to use a recessed brake nut to extend the length of the daruma bolt.  The photos above show how this works.

For the front fender installation, it is easiest to turn the bike upside down.  You can see from the photo above that the cork spacer consumes almost the full length of the daruma bolt.  That’s where the recessed brake nut comes in handy.

The champagne cork spacer is shown above, as installed.  The extra width helps to set up a proper front fender line for my chosen 38mm tire size.

I also used a Velo Orange leather flap on the front fender, as shown above.  The flap sits low to the ground and will help to keep debris off my frame and bottom bracket.

Rear fender line in excellent shape, thanks to the cork spacers.

Champagne, anyone?

Belgium Ale cork spacer

With the front fender now properly spaced, the rear fender set up proved easier.  Again, because of the positioning of the eyelets on the dropouts, it was necessary to cut the stays to the exact length needed for my 38 mm tires.  Champagne or Belgium Ale corks respond well to a metal file, so they can be shaped to follow the curve of the fender.  My porteur style rack allows for a fender attachment, as shown above.  I’ll wait to set that up until I’ve test-ridden the bike and adjusted all of the accessories and components.  Meanwhile, I’m going to enjoy a glass of Champagne!

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.

Nitto lavender anodized stem

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.

Rivendell Appaloosa

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?

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

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.
