Gear Talk / Re: 11-32 vs 11-34
« Last post by salabes on April 22, 2014, 06:54:29 am »
George here, original poster. Now that you guys have put a fear in me, and wandered off my original querry about the 11-32 vs 11-34 question, my take away is - spirits undampened but there's no shame in walking. If I'm not too proud to walk, then perhaps the switch to a 34 becomes irrelevant.  Fascinating discussion you guys are the best. Plan to leave Yorktown 5/31.
Thanks
George

As you said, the math is the math.  It works out exactly right.  As for 8.8% seeming low for the hill, well, that is the right percentage.
Yes that is probably the correct average percentage for the climb, but I can't think of two reasons why it seems low.  First, the climb is not really steady so if it certainly has sections that are steeper than the average and probably some short sections are substantially steeper.

The second reason is that many of the grades we are mentally it to comparing have signage with a percentage that is much higher than the actual grade.

So you've gained 1365' in 2.92 miles. You plug that into your handy/dandy incline calculator:

and you get a incline of 8.8%,(which seems awfully low for that hill)
Now, the math is the math. I'm sure the incline calculator is giving you the right % for the numbers you put in.

1365 feet elevation gain
5280 feet per mile
2.92 miles
2.92 x 5280 = 15,417 feet
1365 / 15417 = 8.85%

As you said, the math is the math.  It works out exactly right.  As for 8.8% seeming low for the hill, well, that is the right percentage.

Whether you have a 32 or 34 big cog on the cassette, it won't make any difference climbing, you won't notice any difference pedaling.

Good plan. You won't have any problem leaving on June 11. The Great Parks South route will be gorgeous in June. You can either ride up Left Hand Canyon (if it's open by then) to Ward to join the Great Parks South route, or you can ride through Lyons and up the South St Vrain canyon. Try to ride over Trail Ridge Road on a weekday, and start early in the morning. You can pick up the TransAm in Walden (a nice little town with a great town park you can camp in). Try to get through Yellowstone before July 4 to avoid the worst of the crowds.

Sounds like a great trip. I've ridden it all.

This has wondered pretty far off the original post but we've gotten into the territory of something I've wondered about for some time.

I went back and looked at the trace (I have a Garmin) from my ride from Vesuvious up to the Blue Ridge Parkway. The exact points are hard to grab and I never corrected the altimeter function but I picked a point at the bottom but where it was already showing as steep and it read elevation 1500' and milage 22.08 and then I picked a point near the top but it had not leveled off yet and it was elevation 2865' and milage 25.00.

So you've gained 1365' in 2.92 miles. You plug that into your handy/dandy incline calculator:

http://www.csgnetwork.com/inclinedeclinegradecalc.html

and you get a incline of 8.8%,(which seems awfully low for that hill)

It was 2 years ago now so I don't remember exactly but the Garmin was reading 10 - 13% the whole way up that hill. And this is not an isolated incident, whenever I'm on something steep and I check to see what the read out is on the Garmin and then cross check it against the incline calculator, the Garmin readout is 2-3-4% high.

Now, the math is the math. I'm sure the incline calculator is giving you the right % for the numbers you put in. But the Garmin is doing it's own math.

Any theories?
It's human nature. When you say that it was reading 10-13% all the way up the hill, that means that it was reading 10-13% every time you looked at it. But when did you look at it? When you were curious, of course. When were you curious? When the hill was the steepest.

This is why we think hills are steeper than they are, why we think headwinds are worse than they are, why we think we ride faster than we do, etc.

I also got rid of cable and for the last two years have downloaded the Tour de France app on my ipad for $14.99 (I think it was that or near that price).  I really enjoyed the app and connected to my TV with an HDMI cable and watched it that way...worked out great and will do it again this year.  It won't be available for awhile yet but watch for it if you have an iPad.  I tried to find a link for you but couldn't find one yet.

Thanks for the reply.  I made little sense trying to remember route names by memory.

I'm considering

My segment A :
Great Parks South

Connecting to B :
TransAmerica Trail

Connecting to C.1 :
Lewis & Clark
or
Continuing on as C.2:
TransAmerica Trail

Connecting to :
Pacific Coast and back to PDX.

now to figure out some mileage for segments.

You can leave June 11. It'll be fine.

However, I have no idea what the "NP loop" nor the "northwest route" are.
