A Bike Made to Fit Mark V
by Mark V on May 14, 2007 at 10:16 AM
Somedays I roll out of bed and I think to myself “Mark, you are a god*&%$ed genius!”
Once in a while I have a brilliant idea. Like my super compact track bike design.
Back in 1999 while delivering pizzas on a 13” Fisher Ziggarat mtb with a 400mm seatpost, I noticed that I could launch an almighty sprint form a standstill since with the low top tube I had so much room to rock the bike. Coincidently, customers noticed that their pizzas were all scrambled in the box after I delivered them. Pizza aside, wouldn’t a track bike frame also benefit from loads of clearance? So started my 8 years of experimenting with track bike design.
For my new Sycip track bike, the tubing and fork will be the biggest differences from its predecessors. The geometry of the new frame will be the ultimate expression of what I laid out in my original Sycip and refined in my Sycip No2, which this latest bike (the 3rd true track frame) will replace. In this geometry, the top tube is equivalent to a 49cm bike, but the seat tube is cut down to 38cm. The bottom bracket is about 1cm higher than most track bikes (2 to 2.5cm higher than a road bike), and the front-center (bottom bracket to front axle dimension) is fairly long compared to a keirin frame. The head and seat angles are steep, but not markedly so.
The super-compact design gets the top tube down out of the way of my knees, so if the sprint begins at low speed (thus low cadence) I can really throw the bike side to side, putting everything into the acceleration. The long front-center makes the bike sure-footed when I lunge forward in the sprint so that the rear wheel stays glued down. There is a line of thought that says that a track bike should be twitchy fast in handling, but I think that a little stability is a good thing in the middle of a combat melee. You have to expect some contact, and most other riders outweigh me. My bikes handle well on a velodrome or on the road.
Would this geometry work for all track riders? Probably not, but then again design is tailored for me. Still, that original track frame changed hands a few times among messengers in Seattle after I sold it. No.1 was well liked by smaller riders, enough so that a local builder attempted to copy the design. The fact that the copy was a disappointment is a testament to the skills of Jeremy Sycip. Sadly, No.1 was stolen late last year. As for Sycip No. 2 that I currently ride, I had standing offers for it even before I committed to the newest frame.
Trek Project One Madone
by Byron on May 14, 2007 at 7:31 AM
While lacking the latest carbon technology, using bonded round tubes and lugs, the Trek Madone is still a favorite race bike contender with it’s predictable, solid handling, reasonable weight, and refined ride. A criticism of Trek is that they rely on 15-yr old technology in their frames. That changed when they started incrementally updating the frames based on the systems approach Lance and company took to bike racing.
What I noticed in the first years of Madones is that there’s a real road feel. Where carbon was always “wooden” and dull feeling, you can feel the road in the Madones. You can also throw that bike into a corner and know what to expect coming out the other side. It’s not the lightest carbon bike, but it’s also not sketchy and descends like it’s on rails.
For 07, the Wines of Washington team is racing on Team Issue Project One Madones – a custom paint job, with Shimano Dura Ace, Ritchey components, and my choice in Hed Jet 60s. I took this photo against a round-about backdrop in the Tri-Cities. We were there for Mother’s day and rode some good miles with old friends.
In upcoming review, we’ll feature the S-Works Tarmac SL, which is about as technologically advanced as a racing bike gets.
Bicycle Saturday and Sunday

Looking for a Sport-Utility Bike
by Byron on May 10, 2007 at 11:05 PM
I’ve been out riding and talking to lots of people recently about Bettie and thought it’d help those looking for a sport-utility bike to collect links to our posts, videos, and resources, into one place.
(that’s Todd Fahrner and Bryan Rhoads having fun)
See the updated review on Bettie 2.0. and note that Bettie 1.0 has been retired.
Bike Hugger Bettie
Bettie is a Bike Hugger project to build a sport-utility bike with a Karate Monkey 29-incher frame, Stokemonkey, and an Xtracycle.
Bettie is based on Cleverchimp’s Super Monkey. We completed the project in late 2006, as a design study, and will iterate another version called Bettie 2.0 in Fall of 2007.
All posts about Bettie are tagged as such and you can find more by Googling. Besides all our posting, Treehugger, Make Magazine, and other blogs have posted about Bettie. We’ve also uploaded videos of our adventures with Bettie to Google.
A sport-utility bike (SUB) is a variety of load-carrying bicycle pioneered by Xtracycle who invented the FreeRadical, a hitchless bike trailer (it attaches directly to the frame instead of with hinges). Wikipedia thoroughly explains the Xtracycle in an entry, including their history, and even links to Bettie.
Longtail Bikes are another rev of SUBs that extend the frame, instead of a Free Radical, to hold luggage, cargo, a family, and even help farmers and merchants in Africa. Longtails are like a tandem with cargo in place of a stoker.
Stokemonkey is an electric motor assist kit for SUBs that adds amazing cargo capacity. Bettie is built with a Stokemoney so we can carry hundreds of pounds of cargo in hilly Seattle. For people that have seen Bettie, it’s the spinning red thing you’re all wondering about.
Surly’s Big Dummy
At Interbike 06, Surly announced the Big Dummy, the first production bike designed to carry passengers and loads without sacrificing speed and maneuverability. Bike Hugger broke that story and will build up Bettie 2.0, as soon as we can get our bike hugging hands on a Big Dummy.
Electric motors, blenders, music, and more are now available for SUBs and that’s just the beginning as more people choose a bike-centric lifestyle.
Where to buy?
You can buy directly from Xtracycle and their dealers and direct from Cleverchimp (maker of Stokemonkey). With Surly’s Big Dummy announcement, it was also announced that QBP would stock and ship Xtracycle’s products and accessories and that’s going to increase availability. Check with your local bike shop. One of the biggest dealers of SUBs is Aaron’s Bicycle Shop in West Seattle.
As of May 25th, 2007, Stokemonkey sales & marketing are on hold.
SUBs, Longtails, and Bettie are easy to find online. There are Flickr collections, Google Video, and lots of bike blogs. Also check the Roots Radical Yahoo Group.
SUB owners are very proud of their bikes and happy to talk about them at length. If you see Bettie, a Supermonkey, or eventually the Big Dummy, stop and say hello.
A Juice Peddlin’ Rig
by Byron on May 10, 2007 at 12:30 PM
On Flickr and from The Juice Peddler is a photo set featuring Tonya Kay; a raw-food-athlete, superhero, dominatrix dance performer, trained aerial stuntwoman, who can use her bike to blend you up one kick-ass smoothie. Check Rock The Bike for more on blender bikes, sport-utility bikes, and the spirit of the bike.
Chain, Chain, Chain
by Byron on May 10, 2007 at 5:26 AM
A chain broke on Bettie earlier this week while taking my daughter to school. Luckily my cat-like reflexes prevented a crash and we coasted back home. I got the chain fixed with a SRAM power link. That’s a simple invention that works amazingly well – no chain tool required.
Breaking the chain reminded me of the one other time I broke a chain. It was during the 1995 Mt. Spokane NORBA. I was nearly dying, suffering like a dog, flying down a fire road, into a hairpin, up a goat trail, shifted hard, and the chain snapped. The 4 dudes that were behind me quickly passed me and my day was done. In a panicked state, I fumbled with the chain tool for 10 minutes or so, put it on backwards once (wrong way through the pulleys), and then for what seemed like an hour later it was back on the bike.
I chased like a MOFO, with the hope that someone flatted ahead, or one of their Tioga Disc Drive wheels (scroll down to see it) exploded, and keep up a frantic pace until the woman’s field arrived. After the initial humiliation, it was very pleasant to ride briefly with Juli Furtado. She was the smoothest rider I’d ever seen. Like a machine, she rolled up with a few girls, chatted briefly (they probably thought I was near a heart attack or something), and just motored on by.
Later, at the finish, that disaster of a race was forgotten and I was determined to not take 15 minutes to fix a chain again. Sidenote: That was the race that Jerry Markee won the sport/expert field and got a seatpost as a prize. When the official handed him the post, he looked inside of the tube and said, “is there cash in there.” For years, that was the seat post joke.
I also remember a ride where we caveman’d a guys chain with a rock to get it back together. Then one time Randy Coleman’s chain broke during a ride, fell off the chain ring, through the pulleys, and flipped up into his Vento wheels, wrapped around a spoke, and he came to a near immediate stop.
What chain stories do you have? Or the worst ever mechanical?
Kozmo Messenger Bag
by Byron on May 09, 2007 at 11:11 AM
Marcus couldn’t be happier than scoring a Kozmo messenger bag off of eBay. I’ve seen these treasured bags in Seattle and San Fran. I don’t know more about their history, other than they were used by Kozmo messengers and last forever. I also periodically miss Kozmo and their tragic dotbomb. It sure was nice being able to call someone up to deliver fight club, a bag of chips, a pint of ice cream, and show up on a scooter wearing that cool bag.
by Byron on May 09, 2007 at 8:23 AM
There’s a joke in the cycling community that bike shops should include marriage counseling with a bike purchase or even offer up some advice with a cup of joe. Maybe set up a marriage counselor network for all them relationships gone bad when the bike becomes a priority as shown in this photo.
I’d think long and hard about putting my bike on the couch – choose wisely with your bike priorities. Unless of course, I was single and the boys were coming over with a case of beer to admire my new sport utility bike.
