New Zealand, UNICON, and me

Friday, January 15th, 2010

New Zealand is an awesome place. The scenery is just amazing, and the country is very open to adventure sports.

I was luck enough to travel with three of my really good friends: Nathan Hoover, his wife Grace Fleming and their son Beau Hoover. Nathan kindly shared a bunch of his pictures with me, so I’d love to show them to the blogosphere.

We first arrived in Queenstown and did some various activities, including a day of trials riding. Andy Cotter let me borrow his super lightweight custom KH20 (with a titanium hub!). Here’s me hopping up a ledge, including a pre-hop that compresses the tire all the way:

I only hop “seat out” to the left, so here is a picture of the front:

One one of the beautiful days in Queenstown, Nathan, Beau, me and Scott Wilton rode up to the top of one of the local hills from the lakefront YHA hostel. Here is a shot of the scenery that Nathan took:

A day or so later I rode my KH36 up to Coronet Peak, where Grace had done some parasailing the day before. The rest of the gang drove the car up, and Nathan snapped a few pictures out the window of me grinding up the hill. This was my last real training ride for UNICON:

Fast forward a few days and we went to visit our friends John and Mandy from Escape Adventures (the guys who ran the Africa Uni tour we did the past summer). I broke my handlebar on the ride, but luckily John had a MIG setup so I could (blindly) fix it up:

An AWESOME picture of the 10km startup that Nathan took. I’m in the center in yellow/white. I got 2nd, while Scott (to my right) got first, but also crashed twice during the race! “Team USA” did awesome — Beau (fourth from the right side of the picture in white) got 3rd.

In the end it was the three USA guys battling it out, with Jan close behind:

The next day was trials. I didn’t have enough space for a 20″ trials uni. I was really lucky, as Tom from Australia kindly let me borrow is really nice KH20. You can barely spot me in the picture, hopping from one thing to another:

The next day was “muni”. I did the uphill and downhill, and then was fairly beat for the 8 mile “cross country” course. I ended up only doing 2 laps (4 miles or so) and saving myself for the Marathon race the next day (which was a good idea), since I’m better at long distance riding.

Nathan also got a few great pictures of me during the Marathon race. Here I am out in the lead:

That’s the short story of my NZ UNICON adventure. It was a blast, but I can’t wait to go back with my lovely wife, Louise and explore some more of the islands.

Unicon Marathon Race Details

Friday, January 8th, 2010

For the past two weeks I was participating in Unicon 15, the bi-annual unicycle convention held in Wellington, New Zealand. Unicon is also known as the Unicycle World Championships.

This is the first time that I have ever gone, and and I had a very exciting and fun time. First of all, it was in New Zealand, a beautiful place I have been dying to go to for quite a few years. But even more exciting was that I actually won a very tough race to become the marathon world champion, riding 27 miles in gale force winds with lots of climbing and fast descents. I already posted a few pictures that Jeff Wilton took at the end of the race, but I also wanted to document my experience so I wouldn’t forget what happened. The Unicon website already has a good writeup, mainly focused on the local rider, Ken Looi: http://www.uniconxv.co.nz/2010/01/07/looi-wins-bronze-in-unicycle-marathon/

The Raceway

The race had a tough layout that included a large hill climb, a gravel path, lots of tough turns, and a small downhill paved (but bumpy) walking/bike pathway that was barely wide enough for two cycles. Oh, and lots of wind.

Here is the overall race layout, ran counter-clockwise (correction from Tom) with left hand turns on the left side of the road (open to traffic). The little green dot is the starting point, which was downwind and flat:

The hill started after the 90 degree turn at the bottom of the map, heading back north all the way to the next right hand turn past the prison. Here’s the elevation profile for more details:

The Race

I had a good seed for the race, since I placed 2nd in the 10km behind Scott Wilton. This allowed me to pull out front early on, and start to set a pace. Unfortunately, there were two speed bumps shortly after the start which slowed me down. I took the first one conservatively and it went quite well, so I figured I would hit the second one at a faster speed (about 18 mph) and not even slow down, but I quick learned this was a major mistake. It was a bit steeper than the first and actually launched me a foot or two into the air. I thought I was going to smoothly land it as the wheel did a loud “squeek” when it hit the ground, but I couldn’t control the force and I was promptly thrown off. Luckily I ran it out, but my worries quickly switched over to someone else behind me running over my unicycle and causing a major pileup. Everyone was quite skilled, and maneuvered around my uni as it was skidding across the ground, and all was clear.  I immediately downshifted my geared uni by hand, hopped back on and realized my handlebar was majorly tweaked to one side. A couple of whacks with my hand straightened it out, and I was shortly back on my way in about 7th or 8th place pumping my legs to catch back up to a group of 3 or 4 leaders.

I slowly moved forward catching back up to the leaders and then settled behind Jan L. from Germany. He took the first sharp left turn a little wide, and I cut in tighter and took the lead up the first hill. I didn’t maintain the lead very long, as everyone else is a lot stronger at climbing. I was soon passed by Ken, Jan, Dave, Sam and Martin as they all flew up the hill. I took it easy and just climbed on up at a steady pace in low gear on my 36 until I hit the top of the hill by the Prison.

I shifted it into high gear, and descended down the hill at a rapid pace. Sam was not too far behind me, but had an unfortunate fall, scratching his arm and breaking his brake. I passed Dave Cox around one tight corner, again taking a sharp inside (steep) descent instead of going wide — the corner was quite tough, and Ken even fell on it the first time through. The road then came to a dead end, with a tight paved (and bumpy) pathway leading back to the ocean. I approached it at a super-high speed, and quickly passed Ken, Jan and Martin all in succession. I popped out at the bottom in the lead (the lower right most portion of the route on the map above), and pulled into the headwind. I took on the wind which forced me down to as low as 5 or 6 mph in low gear, but I loved it as soon as it was a tailwind on the backside heading back towards the starting line, and pushed 18-22 mph all the way until the hill on lap two.

The hill on lap two slowed me down considerably, and Martin on his geared 29′er caught up and took the lead. The wind was starting to pick up, and I believe I saw Martin get pushed off at one point, forcing him to remount (but it could have easily been someone we were lapping). Ken was close behind, and almost passed me as I reached the top of the hill by the prison, but I pulled away on the downhill — but Martin was no where in sight, so I pushed *really* hard (hitting 27 mph) and again caught him at the end of the “single track”, allowing me to pull back ahead on the backside upwind.

By the third lap it was clearly a battle between me and Martin, as I hadn’t seen any sign of Ken on my quick backwards glances. I was in the lead on the uphill, but he again quickly pulled past me. I stuck on his tail until the gravel single track, where I decided to take it easy and allowed him to pull away from me a bit with my hopes of catching him on the downhill. Luckily, my power on the downhill again allowed me to catch up in about the same spot, and I really pushed hard into the upwind to gain some time. It was quite tough, especially with the wind getting stronger and stronger, but I knew where the downwind was and shifted consistently and pushed really hard to gain some time on the last lap.

I worked the uphill on the last lap concentrating really hard to not let the wind blow me off, as I knew a dismount would easily loose me precious seconds. I didn’t see Martin behind me, so I just kept on moving at my normal pace, pushing hard again on the downwind and finishing pretty strong with a three minute lead. I only dismounted once — my crash at the start within the first kilometer.

The top three times:

1.Corbin Dunn (USA) 2hr 5min 39sec,
2. Martin Charrier (France) 2hr 8min 35sec
3. Ken Looi (New Zealand) 2hr 10min 41sec

Franz Josef Glacier

Thursday, December 24th, 2009

For Christmas 2009 I was at Franz Josef Glacier in New Zealand. I rode my kh36 out to it and walked to the top of a little mountain/rock:

Heli-muniing

Wednesday, December 23rd, 2009

Today was one of the best days ever. A bunch of us in New Zealand went “Heli-muniing”. For the uninformed, that is taking a helicopter to the top of a mountain and riding our muni (mountain unicycles) down to the bottom. Totally awesome. The adventurers: Andy (the ringleader/organizer), Irene (his lovely wife), Nathan (who provided rad pictures), Beau (who rode almost everything), John (amazing rode it without a brake!), Scott (who rode it with 125mm cranks), two guides from Fat Tyre Adventures and myself (on the geared 24″ mountain unicycle).

Some of the great pictures by Nathan Hoover.

In New Zealand for UNICON

Monday, December 21st, 2009

A few days ago I left for a trip into the southern hemisphere, New Zealand. There is a big unicycle conference called UNICON in Wellington, which is at the bottom of the north island. I flew into Queenstown in the south island with a few friends of mine, Nathan, Grace and Beau and we have been having a great time! We are going to spend a week hanging out and cruising up north in our rental car, and then two weeks in Wellington for the conference. UNICON is the world championships for unicycling, I’m going to be competing in mountain unicycling and two long distance events. I’m mainly coming for fun, as I don’t think I’m really fast enough to actually win (especially since I haven’t trained enough).

Here are some cool shots of Beau as we were riding downtown.

Adjustable Unicycle Handlebar

Tuesday, December 15th, 2009

I was never happy with the last handlebar I made for my KH36 road unicycle. It attached underneath the base of my seat, and despite it being carbon fiber it still flexed quite a bit and I was afraid it would break. It also never felt quite right — I wanted it to be slightly lower, and slightly more forward. On my KH24 geared muni I have a handlebar that attaches to the seat post and has always felt great. Using the seat post wouldn’t work for my KH36, since I’m short and run the seat all the way as low as it can go when using 150mm cranks. In fact, I think I cut down the top tube on the KH36 frame a bit so I could get it extra low.

To work around this problem I made a new version that attaches to the frame and adjusts vertically when I use different cranks.

Here is a picture of the completed setup:

IMG_6460.jpg

The individual pieces I made mainly from 22.2mm tubes (purchased from Aircraft Spruce) brazed together. The small piece at the bottom is an adapter to attach the brake in the direction that I like. I make the little seat post clamps on my lathe, and trim some fat off of them with the milling machine.

IMG_6445.jpg

The base attaches to the frame:

IMG_6448.jpg

The top T goes in, and can be adjusted up and down. I could also replace it if it ever breaks or doesn’t work the way I want.

IMG_6450.jpg

After the brake is installed:

IMG_6454.jpg

Top view. Notice that I run a set of bar ends backwards. I use these when riding rough terrain, or for climbing steep hills. I really prefer it to the typical front plastic handle found on nearly ever unicycle.

IMG_6465.jpg

After I finished making it, I painted it with 2 coats of gray primer, 2 coats of black, and 2 clear coats.

Riding with it is a dream — it is exactly the handlebar I want. In theory I could also use this setup like a “V frame” unicycle, by tilting the seat forwards a lot and dropping the front handlebar post down all the way, but I haven’t tried that yet.

Tandem Unicycle Video

Monday, December 14th, 2009

Here is a short video of me (in the back) riding the tandem unicycle with Jason. This was our third try. Click to download the little iPhone 3g movie.

Screen shot 2009-12-14 at 7.05.57 AM.png

You tube version: Tandem Uni on YouTube

With practice, I’m sure we’ll be able to ride it. Louise and I also tried, but only for a short bit. We were going to work on riding it this past weekend, but she had to go to Shasta for a family emergency.

EDIT: For all the traffic visiting, I recommend watching the Africa Unicycle Video. It is much better!
