A better city bike

I have three* bicycles, a road bike, a mountain bike and a town / hack bike**.
The one that is used most frequently (as opposed to the one that does the most miles or takes the hardest knocks) is the oldest, cheapest and ugliest of the three, a hack bike in the classic sense. It has mudguards, a rack, 28mm semi-slick tyres, a single-speed converter and security bolts on the axles. It also has a coating of grime so thick that it serves its own anti-theft protection purposes, but it's a few things away from a perfect city bike.
So what might a perfect city bike look like?
Well, one thing you can guarantee is that it would look nothing like the various ridiculous concepts that get splashed around every now and then. Take this one. Please just take it. With that much fancy carbon-fibre on show you can guarantee that if you don't someone else will. As long as it's not raining of course, because there are no mudguards. And as long as there's nothing to carry (no rack). And it's full daylight (no lights). And...
I'll stop there, you get the picture.

So, again, what might a perfect city bike look like?
I think there are a few constants that would be welcome anywhere:
Integrated lights. Good ones, one that will do a job both to be seen by and to be seen, built into the bike so as to be theft-proof and running off a dynamo with a back-up battery for the traffic lights.
An integrated lock. I don't want a d-lock swinging off my handlebars and taking chips out of the paintwork, worse I don't want to arrive and realise that I've left my lock at home.
A belt drive. Whether linking to a hub-gear or a single-speed (we'll come back to that) a good city bike is one that you arrive on clean and presentable (or at least as much as you left the house). I want a nice clean belt-drive (this at least the bad-example above does get right) and I want it enclosed as much as practical. If I forget my bicycle clips I don't want that to mean that I need to buy a new set of trousers because of chain marks all down the right leg.
Some kind of secure compartment on the bike where my emergency toolkit can live without needing to stuff my multi-tool, pump etc into my pockets every time I go to the pub.
Integrated mudguards. This should be optional, not everyone lives in such a god-forsaken climate, but if you're selling a town bike in northern Europe then full guards, with mud-flaps should be there as an option.
An integrated rack. Again optional, but a key job of a proper city bike is to be able to transport stuff around. Personally I don't like cycling with a rucksack, give me somewhere for my stuff.
Security bolts on the wheel QRs. I don't want to be un-hitching a wheel every time I lock up, sorry, I just don't.
Tubeless tyres. Possibly a bit controversial this one, at the moment there isn't a lot of choice in road tubeless road tyres but, having switched to tubeless on the mountain bike about 5 years ago and not having had a puncture since, I'd like that same confidence in my city bike please.
Disc brakes. Again this is potentially a bit controversial but better modulation and more consistent braking in the wet is worth, to me at least, a slight weight penalty. Also brake pads are much cheaper to replace after a crappy winter than rims...

So if those are the constants, what are the variables?
Firstly I see two types of geometry being required; a sit-up-and-beg Amsterdam-style option for those who prefer to be upright and relaxed, and a more aggressive, compact set-up for those who like to go and play in the traffic and take a faster route (my preferred approach).
Secondly there is the variable of local geography; places like Cambridge, or York, or Amsterdam can be easily tackled on a single-speed bike. The topographies of Sheffield and Durham however, require gears.
Finally there is the matter of climate and all-year cycling; for some a full set of racks and mudguards is essential, for some lucky buggers (living in LA or Seville perhaps) rain is simply not worth worrying about and wet-weather protection is simply unnecessary mass.

From these variables I see a line of 8 bicycles being derived: two geometries, each offered in a hub-geared and single-speed version, with all 4 of these available in a fair-weather*** or all-weather flavour.

Below are some sketches suggesting how such a machine might look and work. Feel free to criticise the artwork but know that in doing so you are missing the point...

Integrated lights:

Front and rear would have two LEDs, a flasher and a constant. Both rears and the front flasher would be set up to disperse as much light as possible, the front constant beam would be correctly set up to light-up the road and not on-coming traffic. I think a 300 Lumen high-power and 150 lumen low-power should be sufficient for open roads and lit roads respectively.

Integrated lock and retention point:

A cable lock permanently attached at one end with a spring-retention mechanism to help with re-coiling the cable. The lock is designed to loop around a fixed object and lock on itself. I know it's not as secure as a D-lock but it has practical benefits and the lock you have with you is always better than the one you left at home. The rubber strap on the top-tube stops the lock head rattling around and is designed to be replaceable in the event of  it perishing.

Bottom-bracket locker:


Simple bit of bent aluminium, attached to the frame with some security-head torx or allen-bolts. The lid lock is the same as the one on the main cycle lock so only one key is required. Large enough compartment for a spare-tube, a multi-tool, some instant patches and a couple of CO2 cannisters with an adaptor. Again not perfectly secure, but nothing is.

Initial thinking, Frame options and seat-tube cluster:




A basic upright frame and a compact variant. The kick up at the back of the compact top-tube is to ensure the rear light remains clear of any panniers or racks. The seat-tube cluster is designed so that the frame has a naturally compliant nature to offset the necessary size of the bottom-bracket area. Heavy use of hydro-forming is required but this can be done quite affordably now.
Throughout I have attempted to balance the requirements of integration with use of standard components, hence the lighting wiring doesn't go through the bars and stem, the rear light isn't built into the seat-post and the option remains to have a version without mudguards and rack so that standard after-market parts can be used.
I suspect you might not be able to hubs that have a dynamo / disc and gear / disc combo yet but I believe this will come along fairly quickly.

Looking at what's currently easily available it seems that Gazelle appear to be the closest I can find to this kind of approach but some bits really don't feel that integrated and the locks aren't really fit for purpose. They do seem like nice bikes though.

Anyway, that's my thoughts, what are yours?

* Well, 3 1/2 if you count my share of the tandem.
** This is widely recognised as the minimum number of bicycles by the way, if you were wondering.
*** N.B. Mounting points would still be included on the frame and forks of course.

Wheelsmith 50mm Carbon Clinchers - Review

This site has been very music focused over the last few months so it's probably time to address the balance with a bit about cycling. It would be cheap of me to make reference to my recent win in the tourdepance vuelta so instead I shall give you a quick review of a new set of wheels that have recently come into my possession.
[EDIT] N.B. This is just a first ride review, I'll be posting an update when I've got some proper miles on them and can talk about how they hold up.
These are they:
They're a set of 50mm Gigantex carbon clinchers in the new 24mm width, built onto wheelsmith's own hubs with Sapim CX ray spokes. You can find them in the price list at £740 inc shipping.
I went with clinchers because even the idea of the hassle of a tub puncture puts me off them. Carbon because I wanted something lighter than my current wheels, and deep section because they look nice and if there is an aero advantage to be had, I want it.

So in chronological order: firstly I cannot recommend highly enough the service from wheelsmith. I ordered them on the friday, they were built up that afternoon and arrived on monday afternoon. All the while Derek was also available to answer my dumb questions via e-mail after we'd had an initial chat on the phone.
Almost needless to say they're as true as the scales of justice both horizontally and rotationally.

Secondly then, some numbers. weight excl skewers but inc rim tape = Front 687g, Rear 828g, total of 1515g. Not too shabby at all for a pair of deep rim clinchers.
Wheelsmith supply them with some nice light titanium skewers that weigh 44g the pair and they also include a set of carbon specific brake blocks. More on braking later.
I stuck a new pair of 25mm Michelin Pro 4 Service Courses on and with skewers, tyres and tubes the total weight came to 2205g for the pair. They're replacing a set of Planet-X model Bs with Schwalbe Luganos that weighed in at 2665g so I've saved nearly half a kilo but it's a fine example of the law of diminishing returns.

On the bike they look like this:
After much pressure (mainly from certain people who didn't do quite so well in the fantasy Vuelta) I have swapped the valve caps for black ones. Actually it wasn't much pressure at all, the yellow ones look naff.

Which brings us to thirdly, how do they ride?
Well despite my cunning attempt at a scientific control, this is where we leave all the numbers out of it and start getting into stuff like "feel" and "seemed like" and all that. If you're ok with that then read on, if you just want the numbers then that's your lot.

For the first ride I kept the tyres at the same pressure as I'd been running the (23mm) Luganos (but I might well drop this a bit, particularly over the winter) to try and minimise the variables and, with a similar aim in mind, headed out on a route we knew pretty well: fairly flat, 7-8 mph headwind on the way out, following on the way back.
Being a fair bit lighter I did feel the old "spinning up quickly" effect and generally stamping on the pedals resulted in a sprightly leap forward. Averaging about 18 mph or so outwards I cannot honestly say that the wheels felt any different to the model Bs on the flat. In order to provide an effective control I swapped bikes with my mate (also on an ultegra-equipped pro carbon but still with the old model Bs) unfortunately the change in set up made far more difference to the feel than any kind of kit change (though it did highlight my need to clean up my bottom bracket).
I did notice (or so I believe) the reduced weight going up the hills but I also noticed that as we picked up speed (between 30 and 35 on a couple of downhills - told you it was a flat route) that I was going quicker than I had previously. How much of that is psychosomatic I couldn't say. Similarly though, as we pushed on a bit on the way in, the faster we went the more my mate struggled to keep up. Last time we went out the boot was on the other foot.
Initial impressions therefore seem to back up the standard suggestion that the faster you go the more any benefits will take effect. This makes sense given that wind resistance increases as a square of your speed.

One final word on braking, I haven't used these in the wet yet, in the dry the braking has been fine, not noticeably different to my alloy rims. I will update this post when I've got some wet miles in.

Any questions?

King of the meh

Is it me or has the King of the Mountains title become a bit devalued in the Tour de France recently?
The overall race lead is always going to be the daddy obviously but I'm certain I can recall, in my youth, a period where the polka-dot jersey was considered a bigger prize than the green jersey.
Now it seems to be a bit of an add-on, a bit like the white jersey for the best young rider. It's a nice thing to have but nothing to get too excited about.
Is this just because, with Cavendish regularly featuring in the points competition, the British press have given it that much more prominence? Or have we created that bias ourselves by focussing on the Manx Missile's success?
Has there been a bit of a dearth of top-flight climbers recently that has meant the competition has been swamped by GC contenders instead?
Or is it, as I opened with, just me? Is the polka-dot jersey still as important as it ever was to everyone else?

Cycling, Music and Design (well, poking a bit of fun at fashion)

I think this video just about sums up all the key areas of this blog. And it has lots of swearing in it, which is always funny: http://www.youtube.com/watch?v=hgCqz3l33kU

I'm in the market for a new bike...

...because some thieving little shit stole mine last night. bastard.
So, any suggestions? What was taken was a heavily modded Giant NRS3 (the frame, chainset and stem are original, everything else has been upgraded), and i'd be looking for something similar (though i'm also thinking about a hard-tail).
I reckon i've got about £1500 budget.
What do you suggest?

Yet Another Music, Design And Cycling blog

Welcome, Wilkommen, Bienvenue, in the words of the best band in the world ever*.
So here we are on our first of an irregular series of blogs that will cover, generally speaking, Music, Design and Cycling. I've chosen to write about these three things as they are intrinsically linked in a singular way.
I.e. I'm interested in them.
But nowadays with music comes technology; so i'll be touching on that here and there as well.
In fact, we'll be starting with that.
I've just finished reading a very interesting article on The Technium called Better Than Free; it talks about ways to monetise a product in a world where copies are free. And it's a lot better thought out than most posting on the subject.
This is especially true when read in conjunction with two of his other posts: The Reality of Depending on True Fans and The Case Against 1000 True Fans.
It seems the debate is still very open with only one clear example of someone managing to make the new paradigm (did i really write that? I guess i did, oh well) work being Jonathan Coulton.
I suspect that where we will end up is with the rise of either the marketeer / artist or close collaborations of the two. Either way, it's not enough just to produce music and publish it on the web, nor is it enough just to produce music and play live. There's a huge amount of effort required to persuade people to get off their arses and come to a gig, and then another chunk of effort to persuade them to buy what they can otherwise get for free.
And sometimes that's kind of hard to do at the same time as holding down a day job.
