Bicycle! is written by a working bicycle mechanic and covers everything cyclists need to know in order to care for their rides. This book cuts through the jargon and dreariness of sheer mechanics, delivering maintenance clarity with a touch of humour and radicalism. Readers will learn to make roadside and more extensive repairs, lock up properly and deter rust. Bicycle! is about encouraging society to learn for themselves how to make their bikes work-not because they have to, but because they want to.

would ﬁrst like to tank Seng Cen, Peter Davidson, I Sara Lindstrom, Dan Osterud, Joey Paxman, Kerri Spindler-Ranta, and Nancy Tracy for providing te grapic balance tis book relies upon. I would also like to tank te good folks at te Hub in Minneapolis for te cance to catc up on tings, and everyone at PM Press for te opportunity to put it to words. Finally, te success of tis book owes muc to Moamed O. Hmeida, Moamed O. Amar, Ramatas, Hawa Diaz, Daane, Amed O. Jiyid, and of course my lovely wife Kerri.

o: get on your bike, slip out into te yawn-us, aGouartndtlltn’i—Iwer.oefrswteedtlrsocitkingtinard-ilekeis ing morning traﬃc, ﬁnd your groove, and get art of a new day for so many of Amsterdam, bicycles already account for 35 percent of all trips taken. In Groningen, a Swedis city of 180,000, it’s 60 percent. he vitality tat comes wit riding intoxicates— as te Dutc NGO Interface for Cycling Expertise puts it, “Cycling in reality may be less diﬃcult, less dangerous, faster and more practical tan many people suspect.” Even in Cina, nascent star-cild for te automotive industry, cyclists still outnumber drivers by more tan ﬁfty to one.

Even te most casual glance conﬁrms tat distinct bikes are lately available to suit just about any useful ambition, at points all up and down te quality spectrum, but in te end we ride wat we ave, and tat fairly describes te scope of tis book. Watever you paid for your bike, owever cool it appens to look, it will eventually need some work. he trials of our passage can cost more tan we migt like to tink, in terms of wear and tear, and one day te bill will surely come due. hat day need not overwelm! Bike re-pair begins wit at least two advantages: an injured bicycle is a ell of a lot ceaper to ﬁx tan certain oter forms of transportation, and te mecanical principles in play are also muc more accessible—no gas, no explosions. Given some insigt and a few tools, te odds are good you can do it yourself.

he originalManifesto came togeter in 2005, wen I worked as a mecanic at a ig-end bike sop in San Francisco. his new edition began in te Islamic Republic of Mauritania, were my wife Kerri and I served as Peace Corps Volunteers. As migt be imagined, te distance between te two places left an impression. here was no carbon ﬁber to be seen over tere, let alone titanium; just plenty of cromed steel rims and old cottered cranks. hose dusty old garage relics, donated to groups like Re-Cycle or Bikes Not Bombs? From all we saw, people end up making very good use of tem.

Our spotty internet made it possible to follow tecnical de-velopments in te cycling world—as a longtime mecanic,

Bicycle!

it migt be more correct to say tat tese were diﬃcult to ignore. Yet, from suc a vantage, te latest and greatest also became less relevant. Bikes in te RIM (République Islamique de Mauritanie) are taken for teir last possible miles, literally ridden to ground, drawing te focus back to te opposite end of te spectrum. his edition will duly consider te new mat, in all its ultra-ligt glory, but my eart remains wit te older and more proven tecnology, muc of wic is still in use all around te world. Ultimately I am most interested in mak-ing te most of wat is available, wat-ever tat appens to be, wit te goal of providing te fundamentals for as many cyclists as possible.

here is noting sacrosanct about ﬁx-ing bikes. More so tan anywere else I’ve lived, life in te RIM confirms tat “mecanical aptitude” is merely a

distinct pursuit, not unlike any oter. Circumstance migt lead any of us to ave more or less exposure to mecani-cal concepts and applications, and wit tis te opportunity to develop ﬂuency, but really tat’s about it. Success wit bike repair follows from experience more tan anyting else, wic to a signiﬁcant extent grounds it squarely in te public domain.

he soundtrack to te second edition includes Seun Kuti, Fait & te Muse,Off!, Yo Majesty, Awesome Snakes, Black Angels, Ceater Slicks, Brunt of It, Best Friends Forever, Career Suicide, Frontside Five, Agent Orange, Cut Cemist, Fleet Foxes, Rudimentary Peni, Sisters of Mercy, Joy Division, New Order, Flux of Pink Indians, Bats in te Belfry and Radio Ninja on WMBR, MKEPunk.com, KUSF In Exile, Dark Dark Dark, and te muezzin.

ike oter trades, bicycle repair is in most respects anLd oters will not. he use of force necessarily becomes a specialty. Some of te skills and tools acquired elsewere in life may become useful, as we’ll see, muc more judicious, to take one example—a fairly obvi-ous point, given te scale of many of te parts involved. Our accelerating tendency to rus is best left at te day job, as well: it is possible to wreck just about anyting, done fast enoug.

In te ideal, it’s best to ave one place in particular to ﬁx tose bikes in your care—somewere dry, well-lit, and reasonably calm, if you’re especially lucky. A truly excep-tional worksop will feature a sturdy benc or table as well, mounted wit a vise. here will of course come times wen we don’t ave any of tese tings—a topic furter explored inRoadside Bicycle Repair: A Pocket Manifesto—but giv-en te luxury of planning, it is well wort te time to set tings up rigt in te ﬁrst place.

heBICYCLE REPAIR STANDvery useful to te craft, is toug it is not strictly necessary. he improved vantage stands provide makes it muc easier to see and interact wit a bike’s neter regions; over te course of a tune-up tis makes for a lot less squatting, bending over, and peer-ing beneat. he stands also accomplis te useful trick of removing te weels from te ground, wic greatly sim-pliﬁes our work on te brakes and te drivetrain.

A number of companies produce bike repair stands. hose made by Park Tool of St. Paul, MN, as used in most Nort American bike sops, are peraps te most visible exam-ples. I ave plenty of experience wit Park’s eavy-duty sop stands, but I rely upon one of teir ligter consumer models at ome, and tings work out ﬁne tere as well. he central distinction across teir range of stands is in te clamp—basic models employ simple spring-mounted jaws; better ones incorporate adjustable clamps. his detail be-comes important wit ligtweigt aluminum and carbon ﬁber frames, te tubes of wic may respond poorly to ex-cesses of compression. In trut, we’re really not supposed to be clamping anyting around any of tat at all—muc as cats instinctively carry teir young by te scruﬀ of te
