Ride on upgraded Hunter36s - WOW!

[nathan]

Beau and I got new unicycles today. That is, we installed 29er tubes into our Hunter36s and now fly up hills faster. We went out with Bronson and Rob for 7 1/2 hours of fun. In that long time, we only rode about 30 miles, but what a 30 miles! We climbed and descended over 4000' and most of that was on dirt roads, some rocky and lots steep.

It's a trail that I've only ridden all the way up once before - that was on Muni a few years ago with many dismounts. Earlier this year, Bronson, Rob and Scot did it on Coker, but the idea of riding continuously up these sections was far from anyone's mind. Enter the 29er tube. It is such a radically different feeling. The first hard part is a climb of about 1000' which was hard before (even Beau was walking last time on Coker). This time we never thought of dismounting. After a rest, we headed up the second section. Even though the fog had lifted and the temp was shooting up to about 90F, we cruised the infamous "Wall" section - Beau dismount-free and me with one caused by a microscopic rock. Unbelievable. This was a really hard Muni climb a couple years ago with 170mm cranks.

From there, we had rough rolling fireroads for a while, then a several mile descent that was very steep. The 152mm cranks felt like 125s and we cranked on the brakes hard. After a stop for lunch and to repair a flat (thorn that Beau had picked up), we headed back to Aptos via all small back-roads. Quite a bit of climbing in those last few miles.

Training does pay off. My legs feel now as if I didn't ride this weekend - amazing. Bring on the Alps. I would say that it will take some time to get used to the new cycles. We each had some UPDs on the rough road that we wouldn't've had with the heavier cycles. And it's possible that the thorn that caused Beau's flat might not have with a Coker tube. But no matter, we're either sticking with these or eventually upgrading to tubeless.

Here is a link to some photos - and GPS track links are in the gallery. Also a link where you can race Bronson's GPS against mine. Photos etc.

Let me know what you think of the new hosting site, Smugmug. I have given up on WebShots forever.

Sounds as if the Alps are going to be a piece of cake for you guys. Interesting that lighter tubes make such difference when ascending. But they also seem to give a bit lesser control. Did you ever think about changing to the smoother Qu-ax tyres?

Which 29er tubes did you use? Presta or Schrader?

That woudn't have happened with tubeless . And you save the same weight as well as get a more supple ride. I'm still a bit curious about the number of people getting punctures/blowouts with 29'er tubes- surely the extra effort in changing and repairing each punture would be better spent going tubeless in the first place?

Mr Chicken the II: I think once you get used to a lighter wheel it handles better because you have more control over the wheel, not the other way around. Dropping 250g of rotational inertia is like giving you an extra gear- riding 125mm cranks feel like 150's would previously.

That looks like a really cool ride Nathan. Oh, Smugmug looks classier than Webshots too. I like how they have a large picture as well as the thumbnails.

See you in the Alps!

The Alps will be no problem for you guys, enjoy them. They are not HIGH elevation, like the Rockies, so you should hammer up them! Have a great time.

John, the tubes we are using are Schrader valve, 700x50-52C which are also marked 29x1.9-2.3. They are made by Kenda for Summit. Had to order them from a LBS but they came very quickly - $4.99.

Bronson switched to these a couple of weeks ago, but at the same time he switched to the lighter Tom Miller spokes. He raved about the difference, but he lost a whole pound in his wheel.

Ken, the problems people are having with the tubes is installation, not riding. It is very easy to damage the tube when putting on the tire.

Well, fellow poultry man, I am glad to hear this because I just succeeded mounting a skinny tube on my airfoil rim. I will need that extra control especially when going downhill.

Okay Nathan, you got my attention. I need anything that helps climbing long painful hills. Switching tubes sounds much easier than training, and I can come up with $4.99.

Actually, since I ride off road a lot on my 36, and I really hate flats, I may go the tubeless route. Gizmoduck, how come you never told us how good tubeless was before?


That is another crazy day of climbing you guys did. Congratulations on reaping the rewards of all that training. I am sure it is great to be heading off on the Alps trip with that kind of confidence.

Good photos, and Smugmug works well.

Nathan, I have to wonder if the reason your blowing up these previously difficult hills is because you've been training so hard for the Alps. Certainly, your very in tune with your strength and I don't doubt your noticing a difference because of the tubes. I'm just wondering if you might think its partially because of all your recent training.

That's amazing that the lighter tube makes that much difference. How much is the weight difference?

i think the coker tube is like 2 pounds or somthing.

about flats, a 29er tube must be pretty thin after its streched and pumped up to fit a 36er.

[nathan]

Nick, believe me: anyone would notice the difference who has ridden a Coker before. However it is not quite what Mr Comedian Wallis suggests, an alternative to training. You would maybe call it "squirrelly" or "more responsive" or "harder to control" as well as lighter. But once you get used to it, all you would say is that it's lighter and better.

Could I have done the same ride with the old tube? Absolutely. Climbed as easily? No. The day after the ride I have no feeling at all that I rode - no soreness, usedness, literally I cannot tell that I did that ride yesterday. Would that be the same with the heavier wheel? Maybe but somehow I doubt it. It's a much bigger difference than you would ever predict just from the fact: I reduced 260g of weight from the outside of the wheel.

But I have Maybe I didnt' emphasise the point enough- do a search on 'tubeless tyre' and you should come up with a few threads where I rave about it.

Anyway, a tubeless tyre is:
- as light as using a 29'er inner tube- save ~250g/wheel
- stops small flats because of the Stans Goop that seals up small holes
- Big holes will give you a flat regardless of whether you are using tubess or not. But the Coker tyre is pretty thick, so unless you ride over a kitchen knife pointed straight up, it doesn't happen often
- Rides nice because it has a more supple feel (= less rubber).
- It's soaks up bumps better
- Is just as easy and cheap to put on if you allow for the fact that people have blown up several 29'er tubes in the process of getting them on
- No worries about pinchflatting
- you can run whatever pressure you like. Put it down real soft for off-road
- Did I mention it rides nicer?

Nuff said

Ken

p/s It's still going well- 1x24hr Record attempt, 1x12hr Mountainbike race and 1x160km Road race later. Soon to include the Alps on that list.

pp/s I noticed a heap of difference when I went from the Standard Coker Spokes to Tommy Millers SS spokes too- you save just as much weight (if not more), although it's slightly closer in to the wheel. Add Tommy Miller spokes and tubeless together, and you'll want to ride your Coker all day and all night.

..

Actually, I have read all of your threads about it with great interest. That's why the big

I recently got my awesome Livewire (Stockton) wheel and noticed a lot of difference over the stock Coker wheel. Now that I am used to that, I may be ready for the next step.
Thanks for all the info on the tubless, Ken. We may be slow to accept, but we have been paying attention.

So what do you think of using this to your advantage in future training situations? Maybe you do 75% of your training on the "heavy" wheel to build muscle and endurance and then switch to the "light" wheel for the last 25%. That way, your getting used to the "squirrelly"-ness before the main event.

This could become a new training technique - like jogging with weights.
