Vendetta vs other of my bikes Coastdown test
Hi Y'all,
I'm a newcomer here, My name is Paul Brown and I live in Santa Rosa CA. I grew up in my family's bike shop in Anaheim and opened my own in Marin in 1980. In the 1980's I spent a lot of time building , designing , and tweaking DF bikes for Tri use. I set up Paul Solon's RAAM winning bike in 1989 and the TT bike he used to set the 12 and 24 hours unpaced national records at Hellyer Park in 1993. 272mi/12hr, 509.29 /24 hr. Other riders I assembled bikes for won the USTS long and short course Nationals, Ironman Japan, Ironman Tahiti, Ironman Canada, the Vineman.I worked with the US National TT squad in 1986 in Leadville getting ready for the World Championships refining rider fit and shoe cleat placement. I've ridden a number of centuries, 23 double Centuries,(two on a track bike w/ no hand brakes), so I've experienced the pain of long hours in the saddle. I've been intrigued by the records Maria Parker has been breaking, and admire her ability and determination to take that much punishment to achieve her goal. I've also been intrigued by the MBB front wheel drive format and jumped at the chance to test a Vendetta against other bikes I own. I have two of Steve Delaire's 'bents, a ti pursuit 700c/451 with a Mueller fairing and a Tiger 406/406, which is a fun and fast street machine and a good climber. In my tract there is a smooth street about 3/16 ml long that drops evenly about 110 feet. Not a huge grade, but useful for rolling resistance as well as aero resistance. I rode one of my 700c DF frames, the two Rotators and the Vendetta to get some comparison numbers. All tires pumped to max rated pressure. It was harder for me to balance the vendetta taking off, the boom got in the way of being able to fully sit up and the bike wandered in less than a straight line on the two slower runs. I posted the best runs of the other three bikes and all four of the Vendetta. I ride a 61 cm DF so am taking up some airspace on that machine. The results:
DF Mikkelsen on the hoods: 1:14.2 min
DF Mikkelsen on the drops: 1:11.3 min
DF Mikkelsen full tuck: 1:08.1 min
Rotator Tiger 406 wheels unfaired: 1:07.2 min
Rotator Ti Pursuit unfaired: 1:07.0 min
Rotator Pursuit w/fairing 1:04.1 min
Vendetta run 1: 1:01.6 min
Vendetta run 2: 1:05.8 min
Vendetta run 3: 1:03.4 min
Vendetta run 4: 1:04.3 min
Vendetta run average: 1:03.8 min
I was in a bike accident 14 months ago on a DF when a car made a left turn into my path. I hit it doing around 20mph. The impact knocked me out. The impact sheared the front q/r, bent the front axle, blew the front tire and broke the carbon fork. I bent the left Ritchey crank in when my left knee hit the car. It ripped the speedplay cleat apart on my shoe and I flew about 17 ft and landed on my right side, arm up to protect my face. I had a comminuted fracture of my right scapula crushing the outer 1/2", tore my ac joint, pushed in 7 ribs which are still tender, tore the medial collateral ligaments in my left knee, bruised my left hip socket, and had some crumbling of C6 and C7 vertebrae in my neck. I kept my sense of humor, however, and am very thankful the accident didn't paralyze or kill me, and good news, I'm riding again.
The fixed angle 23 degree seat pan on the Vendetta was a problem for me. I couldn't see the road ahead through my glasses. I cut a piece of foam to prop up the seat pad to 26.5 deg, and added some foam to the front of the headrest so I could see the road through my glasses. I started on a loop I've done a number of times. The Vendetta doesn't seem like its going as fast as it is, it rides that well. I was doing about 23.5-24 with little effort. The vibration through the seat made my glasses buzz and blurred the road when leaning against the headrest. I also started getting a cramp in my left bicep from the closed up arm position with drop bars and ultegra sti shifters. About 4 miles into the ride I had an older Ford van swerve into my lane and make an abrupt right hand turn. I narrowly missed him, but suddenly the boom felt ominous to me. A head on impact like I sustained last year might crush my chest against the boom. I had covered the bolts that hold the bar clamps with electrical tape before my ride, as they had sharp edges and I scraped my arm on one while installing the extra seat pad. I wonder if a hinged boom, with the pivot at the headset, might be a prudent design consideration. It would allow easier ingress/egress and might keep the boom from hurting your upper body in the event of a frontal collision.
This is an awesomely fast ride. I found it climbs better for me than my Tiger which has a stiff frame that I'm used to.
Nanda Holtz at Spincyclz in Petaluma CA. graciously lent me his coveted Vendetta for a day for testing. A Great guy and interested in making the bikes he sells really useful for their riders.
