The Lighten-ing: Seatpost

I recently described the upgrade to the set of wheels on my Cycles Toussaint Vélo Routier v2, a low-trail, 650b bike. Not that you care, but you can read it here: https://mondoblahblah.blogspot.com/2021/07/the-lighten-ing-wheels.html

There are a few other upgrades I've been meaning to make, foremost among them, a new seat post. There was nothing inherently wrong with the Kalloy seatpost that came with the Velo Routier DIY package. It is a simple, classic-looking seatpost that fits this bike perfectly. But there was a minor (hopefully just cosmetic) manufacturing defect that has always bugged me a bit. At the rear of the post there was a tiny "dot" of adhesive foil stuck on for no apparent reason. One day I mindlessly started picking at it, as one might a scab, and once pealed off, it revealed a hole in the post, an obvious defect in from the casting of the aluminum. What have we here?! I exclaimed.

Too lazy to make a fuss over a $19 seatpost, and presuming the defect doesn't constitute a high risk of failure, I left it. If that's the bike's biggest problem, I'm certainly happy to live with it. And did. For a long time. But then the binder bolt on the Managing Partner's fancy-schmancy carbon fibre Specialized seatpost snapped off. 

Well, as you may imagine, while purchasing a new seat post for her, I couldn't resist the temptation to slip an extra into the ol' René Herse Cycles shopping basket. So it is that the Vélo Routier has come to sport what I think is one of the nicest looking seatposts available, the S65.

Now I am plum jiggered if I know why it's called "Crystal Fellow". Sounds like a sex toy. But as the box says, it is forged alloy pillar seatpost made in Tokyo, Japan. The Managing Partner's bike is a teeny-tiny "compact" frame, so she needed the 300mm version, while my Vélo Routier shows only the traditional "fist-full of post" so I got the 250mm. It's the same length as the original Kalloy post. So, of course I had to weigh them!

The Kalloy seatpost weighs 261 grams

The Nitto S65 "Crystal Fellow" seatpost in 250 saves 10 grams!

In addition to being marginally lighter (c'mon, ten grams?!) the Nitto is forged, which I presume means it is stronger than the obviously cast (K)alloy post. I suspect this makes the point about weight: saving that 10 grams cost me about $86 with shipping. So, you know, about $9 per gram. Cheap by bicycle standards but given there was nothing functionally wrong with the original, a bit of an unnecessary extravagance to be sure. Nevertheless, I love Nitto products, want to encourage the company to keep making them, think the "Crystal Fellow" looks just a bit nicer and hey, 10 grams is ten grams, am I right?

The Lighten-ing: Wheels

For those of you who don't know, a few years ago I smashed up a midlife-crisis-carbon-fiber-super-bike and replaced it with a low trail do-it-yourself-built steel rando bike from Cycles Toussaint of Alberta, Calgary. Read all about it here: https://mondoblahblah.blogspot.com/search/label/VR2%20Build

I've swapped some cockpit parts over the years, but in general, the bike looks like this:

Cycles Toussaint Velo Routier V.2, 51cm

With the exception of the tires, handlebars, stem pedals and bottle cages, all parts came with the Cycles Toussaint Velo Routier DIY package. Though I could never quite get the front derailleur adjusted perfectly, I've been extremely happy with the bike, and find I like it more the longer I own it.

People who ride bikes like this, absolutely should not be weight weenies. The frame is steel, the rims are metal, the tires are wide. This bike is designed and built to keep the rider comfortable over long distances, not to race. So it's heavy compared to the bike it replaced. Ready to ride it weighs just about 32.6 pounds as I originally set it up. 

For a while I have been thinking of getting a second set of wheels. Nothing particularly wrong with the original set, and the kid at the local bike shop even complemented me on them when I took them in to get trued (I can do a basic job, but I like to periodically take them in to a professional get the dish and spoke tension right). My first inclination was to order a new set from Cycles Toussaint, as they have a wheelset for sale for the insanely low price of $169. The set, like most of their components, runs a tad heavy at nearly 1,900 grams, plus another 100g or so for quick releases. 

I had heard Russ Roca from PathLessPedaled mention he thought "good" wheels should generally not exceed around 1,500 grams, so I thought I'd look around to see what my options were. It doesn't take long to discover there aren't a lot of good options for 650b alloy "box" style rims on the market. In fact, aside from those available through Cycles Toussaint, only Pacenti seems to offer pre-built wheels that fit the bill. Velo Orange used to offer a nice set, but I haven't seen them actually in stock for a number of years and they seem to have been captured by the disk brake tractor beam. Of course I probably should (and thought I might) break down and get a set built at the shop, but that would require more effort than just plunking down my credit card, dammit!

After reading Jan Heine's description of the wheels he built for the bike he rode during the 2019 Paris-Brest-Paris ride, I decided the Pacenti Brevet 650b was close enough and somehow ordered during a brief window of availability during the Covid-19 pandemic. Looking at their site, it looks like there's now a backlog of at least 10 weeks, as is the case with a lot of products these days.

Built just for me by someone named Ryan from Devon, UK!

Ryan from Devon built my wheels with their own two hands.

Fortunately, before the end of the world, I acquired a back-up set of tubes and Loup Loup Pass 650b x 38mm extra light tires from what was then still Compass Bicycles, now René Herse.

Compass Cycles Loup Loup Pass tires and Schwalbe SV21A tubes

I've only used two models of tires on this bike in the three or so years since I bought it - the white Pacenti Pari-Moto tires that came with the Cycles Toussaint DIY package, and the Compass Loup Loup Pass extra lights. Both are made by Panaracer in Japan, in what looks like nearly identical molds. Both are absolutely outstanding quality tires, the primary difference being lifespan - the Pari-Moto tires are what Jan Heine has described as "event" tires, and for me at least, were very short lived. But they performed every bit as well as the Loup Loups at about half the cost, so you decide. If you like the white, buy two sets and just swap them out twice as often.  

A note on tubes: The René Herse site recommends Schwalbe SV14A tubes for the 38mm tires. When I originally installed the Loup Loups, I did so with those tubes, and both of them blew out. I allow that there may have been a problem with my rim tape or something (though the tubes blew out on both front and rear rims), but having blown $34 to smithereens, I elected to get some SV21A tubes and haven't had a problem with them. 

Technically the SV14As are listed on the Schwalbe tube-finder as 26 inch tubes which Jan has pointed out are plenty big enough for 650b rims (there's only about 3% difference in circumference, which should be fine). The SV21A tubes, specifically rated for 650b rims are a touch heavier (just under 3 ounces). I'm willing to suffer the extra 80 grams for just a touch more confidence.

I was originally going to install a new MicroShift 10-speed cassette on the new wheels, but I figured while I was updating the wheels I might as well "upgrade" the cassette as well, at the risk of introducing yet another variable to complicate matters. So I installed a SRAM PG-1070, 11-36 cassette. Not sure it's superior in any way to the much less expensive Microshift alternative, but it saved about 2 ounces. I used one of the "extra" KMC 10-speed chains included with the DIY package.

So I have the new Brevet wheels on the bike with new Loup Loup tires, Schwalb SV21A tubes, SRAM cassette and a KMC chain. Just in case you don't know, here's a Rivendell video demonstrating the process of swapping out the cassette and chain:

So, does all this extra effort (and money - probably about $350 more for the "upgraded" wheels and cassette) yield any benefit? The simple answer: hell, yes. I can't say it's completely revolutionized the bike's performance - it's still piloted by a middle-age slacker after all - but there is a definitely a notable improvement to the ride quality. Spinning up to speed seems quicker, as does sprocket engagement after coasting. I'm not sure it's actually faster, but it feels faster and just somehow "smoother". 

I suspect a large portion of the improved ride quality has to do with the quality of the freehub, which is undoubtedly of better quality than the DIY hub. But weight might also play a role, particularly in the front which, despite having four (count 'em, 4!) fewer spokes, feels more "definite". I will test my freehub theory when I next swap out wheels. When ordering the Brevets I picked up a Pacenti freehub to get to the $500 free shipping limit. I'll put that on the stock Cycles Toussaint wheels with the MicroShift cassette and see how it compares. Of course that probably won't be for another year, so...

The conclusion is that I'm super happy I went this way. Nothing particularly wrong with the stock build; it is what it was supposed to be: entry-level. But the stock wheels really do a disservice to the bike. This one upgrade reveals the true quality of the frame with its compliant steel and uncommon geometry. When supported by higher quality components, the Velo Routier absolutely shines. I'm happier with the bike now than when I bought it.
