Nifty Ten Fifty 2017 Results

This year's Nifty Ten Fifty featured fantastic weather, and a hardcore group of accomplished climbers. We had a bit over 50 riders at the start, with nearly 40 actually completing the entire course, signing waivers, and posting times on the tracked KOM climbs. I mistakenly suggested that only Marin Ave, and Claremont/Grizzly/Vollmer would be tracked, though I meant to include Thorndale. As such, you will see Thorndale included in the results below.

The self guided model seems to be working OK, with most riders grouping up and finding someone who either knows the course, and/or is competent with GPS navigation. Registration opened at 8:30 AM with the official start at 9:30 AM. Most riders left before 9:30, however a core group of perhaps 20 strong riders left at 9:30. Sarah and I were immediately dropped on the tandem by this fast group, and ended up doing most of the ride solo.

We had some leisurely stops at Safeway in Montclair, and ForneƩ in Berkeley near Claremont Hotel. We also had a sidewall blowout, but fortunately were carrying a spare tire, de rigueur on the tandem, so it was an easy fix.

Next year I plan to start the ride earlier, and also compress the start window. Registration will open at 8:00 AM, and the official start will be at 8:30 AM. This will hopefully make the ride more social, make navigation easier through better crowd support, and get us out on the road a little earlier for better traffic conditions. Your feedback on this change is welcome.

We had the usual fast guys this year, with a few newcomers. Nifty vets Josh Dapice, Hans Detlefsen, and Bill Laddish, lit up the climbs this year as usual. Also riding very strong were Luiggi Zuniga, Eric Chodoroff, Mike Conway, and Max Noda.

Thorndale, one of the KOM climbs, is a beautiful, steep, emote, bumpy, single lane road with very bad pavement. Pro Tip: Bill Bushnell notes that the fastest line is to stay on the sewer line patch, which is the smoothest way up the climb. Photo courtesy Bill Bushnell.
For the women, I was a bit disappointed at the slim turnout, but we had three very strong women on the ride. National caliber Masters rider, and Nifty Rookie Jennie Phillips was the fastest woman, with close competition from a younger racer, and also Nifty Rookie, Amy Moor. Both women underestimated Marin Ave, and had to do a bit of walking at the top. Both hit their stride on later climbs, however, posting respectable times. Sarah Schroer, the current QOM holder on Marin Ave, was stoking the tandem with me, so is not included in the women's results. But watch out... she'll likely be on her single next year.

This was the second time around for Sarah and me on the tandem. One other couple has competed the Nifty on a tandem, Tom and Cindy Long, many years ago.

The Lanterne Rouge goes to Del "Chilly D" Miranda, who was last on every climb. But it wasn't easy... He nearly blew his perfect record by finishing just one second slower than Paul Capewell on Marin Ave. Had he beaten Capewell on Marin, he'd still have won the Lanterne Rouge award, but it would have been "tarnished." Disaster averted, he maintained comfortable last place margins on the two subsequent KOM climbs, Thorndale and Claremont/Grizzly/Vollmer. When making a bid for Lanterne Rouge, consistency is of paramount importance.

Bill Bushnell showed up on his super fast e-bike, with a new system. He's using a hub motor so he can regenerate to recharge the battery, but this means the motor will get very hot on steep climbs. He had to stop twice on Marin to cool, even with pedaling hard, but after that, the bike seemed to be OK. Bill doesn't post his times on Strava for obvious reasons, but I may be able to get him to share his segments. (ed. note: See Bill's comment below for accuracy and clarification).

A big thank you to everyone who came out and rode in the perfect weather for the 2017 Nifty Ten Fifty. Most riders showed up on time, signed waivers and made donations as suggested, and were well behaved out on the road. Hope to see all of you next year. Results below:

  1. Hi Paul,
    Thanks for organizing this year's event and for arranging the excellent weather.

    My objective this year was to complete the course on the bike. It's a tough test for a hub-motor'ed e-bike with a legal power limit (750 watts at the wheel). I was faster on the climbs in 2015 with a through-the-gears system.

    Although I had a couple of extra cooling aids in/on the motor (ferro-fluid and heatsinks), I had to stop a number of times to allow it to cool: four times on Marin, once on Lomas Cantadas, and several more times at various locations along the course. Average motor temperature was 83C, and for 55 minutes of running time the motor interior was >100C, which reduces overall efficiency.

    The hub motor drive system has some distinct advantages in spite of its unsuitability for a Nifty-like course: (1) quieter than a geared motor, (2) simpler drivetrain--fewer critical parts to fail, (3) more efficient than a geared motor provided the terrain is not extreme (e.g. grades <10%) and provided regeneration is employed efficiently, and (4) motor (regenerative) braking solves a long-time problem I've had overheating my friction brakes, both rim and disk, leading to blown off tires, rapid disk brake pad wear, or busted spokes (caused by the howling of an overheated disk brake system).

  2. Bill, Thanks for the comments and clarifications, and the sharing of the Strava file. Seems like the hub motor is overall a far superior system, as long as the climbing is not severe. Based on your comments, it would seem a hub motor with a 2 speed internal system would be a good idea, but not sure there is a big enough market for that, and it would likely be very expensive.

  3. Crystalyte used to sell a direct-drive hub motor with two sets of windings, one for speed, the other for torque, or so it was marketed. Assuming one uses a capable controller the most important aspect is the copper fill, so the unused set of windings is just dead-weight.

    If I want to climb Marin more efficiently with a DD hub I've got a couple of choices: (1) get a bigger motor, or (2) lace the same motor into a smaller wheel. (1) means giving up a rear cluster and going with a single speed, and (2) changes the bike's geometry and handling more than I'd like.

    A third option is to run two separate systems, a through-the-gears (TTG) for the steep terrain and a DD hub for the rest. But, that adds complexity and weight. My bike already has too much stuff on it.

    As for "far superior", I'm not sure I'd go that far. Although hub motors are still popular in commercial e-bikes, TTG systems are gaining popularity, esp. those using OEM drive systems by Shimano and Bosch where high torque at low-speed is desirable.

    To get an idea where the market is going, take a look at the offerings at one of the larger Bay Area e-bike dealers:
    https://www.motostrano.com/E-BIKES-electric-bicycles-s/4468.htm

    Although I admit to a small amount of "novelty bias" as I explore the limits and capabilities of a DD hub system, I am for the moment happier on balance with the DD hub.
