Cotton & Shellac Handlebar Treatment

"I'm against it!" was the response I received from one bicycle shop as I went scrounging up my supplies for my latest project.  Truth be told, that was my first thought too when my friend, Ean Parsons, suggested that wrapping my bars the old fashioned way, with cotton bar tape and shellac would be an affordable, classier option than my re-purposed inner tubes.

Ean Parsons



Ean is one of those guys who lives and breathes bicycles, approaching the whole genre with the sort of reverence usually attributed to a record collector (he's that too).  Where I am someone who is approaching cycling from having been on hiatus from the sport since fourth grade, Ean never stopped.  I respect and appreciate his aesthetic. His suggestion, while initially ignored, eventually peaked my curiosity.  So I asked him if he'd lend a hand for this tutorial.



What You'll Need:

counter clock-wise from top left, Newbaum's cotton handlebar tape-Oak Cliff Bicycle Company $6 a roll , colored assortment twine-Joann's Fabric $4.99 or hemp twine $1.99, throw-away "chip" brush, $1.19, Zinsser Bulls Eye amber shellac-Home Depot $13.78, corks-Ace Hardware $0.30 each, plastic drop cloth-Home Depot $1.19




1. Cotton Tape.  Oak Cliff Bicycle Company stocks Newbaum's, a relatively young company that also makes rim tape, and although other shops may carry it, most don't. I purchased two rolls of gray, and two rolls of orange Newbaum's cotton tape from Oak Cliff Bicycle Company.  Unsure of my color selections, I popped in to a couple other local bike shops and found smug rejection. It's available in 16 colors, and runs 5-7 bucks a roll, but remember to get two rolls if you're going to be wrapping drop-bars.  

2. Hemp Twine. This provides a classy finished look to the project.  Forget electrical tape!  You can get crazy with the twine and wrap it around all sorts of stuff, but for this demo we are sticking to the top center.  I found an assorted bag of colored twine for pretty cheap at Joann's, who also stocks the natural jute kind.  Any hardware store will carry twine, but probably will sell you a larger roll than you need for this project,  however if you think you might be using it for other stuff then it makes sense.

3.  Chip Brush.  I'd like to say that it's worth it to use a nicer brush for this project, but I would argue that cleanup is going to be worse on the environment than throwing that brush in the trash.  While I have no empirical evidence to support this claim, I will just say that most of the elements used to make this brush are natural, and biodegradable, including the Shellac, and you don't need a nice brush for this application.

4. Shellac.  There are many options here, but the easiest one is going to be the Zinser shellac you buy from any hardware store.  While you aren't going to use it all before it goes bad, it's readily available, comparable in price to other options like shellac flakes,  and it's easy.  Flakes are something I want to experiment with in the future,  but for now, easy does it.

5.  Corks.  Of course you can source these from any number of places, but the hardware store offers unused, tapered, natural corks, in a variety of sizes.  They are extremely cheap, and fit better than wine bottle corks, and will take shellac very well. 

6.  Drop Cloth. You can always wheel your bike outside and not worry about spilling, but unless your extremely careful, you're going to get little flecks of shellac on you're bike.  While I don't know how hard it is to remove them, Ean tells a sad tale about getting shellac all over his bike, and not noticing until he was done. It costs less than 2 bucks, so do it the first time at least until you know what you're dealing with.  This can get messy. 


Start With Clean Hands and Clean Bars

Cotton Bar tape is going to suck up all the muck from your fingers, and although your about to cover up your bars, just remember, you'll be handling them the whole time your doing this, so even if you start with clean hands, you may end up getting nasty scum all over your new cotton tape if your bars aren't clean.  Wipe them down with alcohol or some other solvent, or pre-wrap the bars with electrical tape.

start with clean handlebars




Begin With 1/2" Overlap.  Ean learned to start from the top, going away from the bicycle, and while I learned to start from the bottom, going toward the bike, it seems to make no difference, other than giving you a way to remember which direction to wrap (same either way).



Continue to wrap, overlapping about  1/4" to 1/2".  Watch for bubbles, keep it nice and tight, and don't expose too much adhesive before you need it, or else you'll find yourself sticking it to all sorts of things other than the handlebars.



You'll notice once you get to the brake lever bracket, doing a simple figure 8 is going to leave some bar exposed, so before you get that far you should cut a couple 4" pieces of tape and wrap them around the brake lever brackets.  Tuck the ends up under the brake lever hoods. Most modern bar tape is much wider than Newbaum's, and only requires one piece to cover the bracket. We found we needed two strips of the much narrower cotton tape to completely cover the bracket.
you can see how much of the bars and bracket are left exposed if you don't cover them with a small strip

Ean applies a strip over the bracket, we ended up using two for each side


Continue wrapping, making sure you've got no bubbles, you'll want to pull it pretty tight.



Use sharp scissors, these kitchen shears were a pain.  As I noted in the "Tube Wrap" 'how to', there are many slight variations on this subject.  Here, Ean shows how he cuts his tape at an angle, starting from the outside, and finishing towards the center of the bike, different than what I suggested in the "tube-tape how-to". I thought about this for a long time, and realized, it would be better to do it Ean's way if you were using a different tape that was thicker in the middle, like leather or any of the synthetic tapes, due to the chamfered edge,  so better to learn it this way.

Ean cuts a transition starting from the outside toward the center of the bike

Finish by wrapping up to the edge of the center handlebar shim


Go ahead and put your corks in, tuck the overhang into the bars and hammer em in, "good n' tight".


tap the corks in gently with a hammer

Twine

For wrapping the twine, you're going to want to cut a length a little bit longer than one "wingspan" (arms stretched out).  I would suggest doing "two wingspan's", maybe 6-8 feet.  You're not going to need it all, but when you don't have enough it's a real bummer.

Starting from one end of your twine, take a section 6"-10" long and "reserve it".  Run your "reserve" along the top of your bars, starting with the end of the twine near the brake lever going towards the center of the bike.


Start wrapping the twine carefully around that little "reserve" piece, starting from the end of the tape going towards the brake lever.
carefully line up your twine snug, take your time

attention to detail here will payoff


Once you've wrapped about half way of your total desired thickness, you're going to want to take the end of that "reserve" and make a loop.  For the rest of the process, you will be wrapping around both sides of the loop.


Once your twine has reached it's desired width, take the end of the twine and thread it through the loop.

Pull the end of your "reserve" piece tight around the end of your twine.




Cut the remainder of the twine, leaving only a little nub, no more than a half centimeter.



Now pull the other end of the loop, until the cut end from the last step is pulled through.  On the other  side of my bars, my twine did not make it all the way through, however, it posed no problems.
pull the "reserve" end through, it should pull the other end under the twine.

success!

Once you've pulled the end through all the way, clip off the rest of the twine
snip!

You can hide the ends underneath the wrapped twine using your finger nail,

It's easier than it looks!  Rivendell Bicycle Works has an excellent video tutorial that should bolster your confidence.  You also get to listen to Mulatu Astatke while you take it in.

Shellac!

Tape off anything you don't want shellacked.  That includes brake hoods, and handlebars.  You may want to drape your drop cloth over your bike right about now too.  I will say, this can pose a problem if you're working outside.  That cheap, thin drop cloth will catch even the slightest wind and blow right into your wet shellac.  Anchor it down if you foresee this being a problem, otherwise, you may find yourself tossing the drop cloth before you're even close to being done.
Ean was worried that folding my vintage brake hoods back would ruin them, so we taped them back.  
tape off your bars, shellac will stick to them and look ugly
Shellac is messy, and that cheap chip brush doesn't hold much shellac right at first. Go slow, your brush will start to hold more shellac as you work.  Most people like to apply a thin coat and let it dry.  This allows for a nice even application.  If you get too heavy with your coats, you may end up with drips or an uneven appearance.  Also you may find you're happy with less shellac then you anticipated.
take your time, this stuff can get messy
Shellac the corks too, and double check for spots you missed.
Ean finishes up a first coat of shellac
After four coats, I was happy.  Three probably would have been good enough. Four coats made the bars feel a little slippery to bare hands, however, with a pair of leather gloves it feels perfect.
This is one classy look, and, while I may have agreed with that -anti cotton tape- shop owner before, I'm very excited about it now.  First of all, it's extremely durable.  If the shellac starts to wear, you can simply apply another coat.  Second, with the proper pair of gloves, you really don't need all that padding that synthetic materials offer, especially if you're on a comfortable steel frame. And finally, as long as you don't put too much shellac, it's very tactile.  You get lots of traction on this setup.  It reminds me of all the marketing gimmicks that saddle makers have employed over the years, pushing more and more padding, while tensioned leather saddles still remain the hallmark of comfort.  This wrap offers no padding whatsoever.  The bars are skinny and sleek.  It feels rough, and hard, and to my surprise, I really like it that way.

  1. Looks great. I still think it would be too thinly-padded for my taste. I suppose if you wanted more padding, you could lay the cotton over the re-purposed inner tube.

    1. Thanks. I would say thinly-padded may be a little generous, it's pretty stiff! I'd have never thought I'd be Ok with no padding, but I am. I hold the bars differently when I'm riding that bike, I'm not so inclined to give them the death grip. I'm pretty sure I'd hate it without gloves though.

    2. If you want more padding you can try cutting a thin strip of neoprene or thin foam padding and putting it where you will be gripping on the bars. Put it on the raw metal before you wrap. That's what I do.

    1. Send me some pics when you get it done! I'm experimenting with some different kinds of shellac flakes at the moment, hope to post results soon.

    1. Yes, I've had trouble with it my whole life, as you've probably had trouble being a jack-ass. I can type as fast as I can talk, which means I have to read and re-read everything i write two or three times to catch all the grammatical errors. I am, however, working on it. Thanks for the well wishes, and good luck with the jack-ass thing.

  4. I followed your guide on my Kool Yellow 1974 Le Tour (as it was the BEST all-in-one guide...) LOVE the results! I used Yellow cloth tape and Amber Shellac and got a near perfect match for my B-17. Thank you!!

  5. The second coat of Shellac is currently drying and it looks great. I'm just replacing my old black tape with more of the same but the cork and twine are really nice touches. Thanks for the detailed guide!

  6. Thanks for the guide. What colour do you think white tape with amber shellac will end up in? Aiming for a (light-ish) brown, but I think brown tape with amber shellac might end up being too dark.
