Gear Talk / Re: Chain selection
« on: March 02, 2012, 10:47:17 am »
And John N, how about sharing some of that arduously collected data?  What's your chain life average and the range?

I measure my chains and change them when they get to 0.75% stretch. For my last 8 chains, I have gotten mileages of 4,223, 3,414, 3,767, 4,218, 3,348, 3,340, 1,859, and 3,142. That 4,218 and 3,348 numbers were SRAM 991, the 4,223 was a Shimano HG73, and the 3,414 was a SRAM 951. The rest were SRAM 771. Others have vastly different experiences and I have no good explanations why. Some change their chains every 1,000 miles and some every 10,000 miles. The differences can probably be attributed to a wide variety of factors, including how often you clean and lube, whether or not you're a masher or spinner, how often you ride in the rain, how many hills you ride, how heavy you and your load are, how dirty your roads are, etc.

General Discussion / Re: how safe is it to ride in the US?
« on: March 02, 2012, 10:36:24 am »
Although I would agree that the US is very safe both on and off the ACA routes, on the ACA routes you get a lot of "welcome--we're glad you're here" comments. Off ACA routes, the comments hint more of "what are you doing here exactly?" But it's not a big deal.

I think the best way is to ride your route and let us know the actual mileage!!!
I know your comment was tongue-in-cheek, but there are many reasons for differences in actual mileage ridden and official map mileage. I rode the TransAm, which has an official mileage of 4241.5, and I adhered religiously to the route, but my mileage came out 4488. The difference is all those little accumulated trips to the grocery store, the swimming pool, the restaurant, the campground, etc. It only amounted to an average of 3 miles a day, but it adds up.

Thanks Carla for your detailed remarks. That helps my understanding quite a bit (and I found out that I had a math error in my earlier calculation). I'm looking forward excitedly to the availability of the new NT sections 3 and 4.

I'm bumping this because I'm curious and because I'm sure somebody knows the real answer. Thanks.

Yes, the SRAM chains will work fine with Shimano components. Their three basic models of SRAM 9-speed chains are the 951, the 971 and the 991. I only buy them when they're on sale, and I buy several at a time. Often there is only a small jump in price between the 951 and the 971, but a large jump between the 971 and the 991, so I usually end up with the 971. I have kept track of mileage on each chain over the last 15 chains or so, and I do notice that the more expensive ones last longer, but maybe my sample size isn't large enough to be significant. As long as you check your chains frequently for stretch and replace them often, it probably doesn't make much difference which one you use.

Gear Talk / Re: How to avoid saddles sores and rash (hand sanitizer)
« on: February 26, 2012, 10:27:48 pm »
I carry two pair of shorts, the pair I'm wearing and a spare in case I dry camp. (No more, since shorts weigh about a half-pound each, and that's not nothing.) Most of the time, however, I do get to wash my shorts in a sink, under a spigot, in the shower, etc. Even if I don't get to take a shower, I at a minimum wash my saddle contact area with a washcloth. I don't take wet wipes, since a drop of soap, a washcloth and a squirt of water from my water bottle does just fine, without the skin-drying effects of an alcohol-based wipe.

Routes / Route Mileages
« on: February 24, 2012, 05:37:35 pm »
I'm curious as to how map mileages are listed when there are alternative routes. I just got my new Cyclosource catalog in the mail, and I looked up the "Northern Tier + North Lakes" route. So it tells me that if I buy the complete set, it is 4651 miles. Then each of the 12 maps in the set are listed individually, each with a mileage. If I add up the 12 mileages of the individual maps, I only get 4399 miles, 252 miles short of the set total. Now I know that there are several options on this route (e.g., (1) you can go to Waterton Lakes NP in Canada or go through East Glacier to Cut Bank, (2) you can go through Grand Rapids MN or take the shortcut to Dalbo, (3) you can ferry across Lake Michigan from Ludington MI or go around the north side and cross the Mackinac Strait). I also know that the maps contain roads you won't need if taking the North Lakes alternative (e.g., the last half of North Lakes Section 3 takes you back to the NT in Indiana, which you don't need if you're taking the Lake Erie Connector).

So, to refine my question, what do the mileages shown for map segments or map sets include? Are they a sum of all the roads mapped, including the alternatives? Do they count the shortest alternative? The longest alternative? The "normal" alternative? And how do you come up with 4651 miles for the Northern Tier + North Lakes map set.

Thanks.

Has it been a winter with a reduced amount of snow with chances of early mountain pass
It's too early to ask. March is our snowiest month. We're below average now, but we could easily be above average in a month. If I remember correctly, however, I believe you are starting in the East and doing the TransAm westbound with high-mileage days. So you'll have roughly 2400 miles under your belt by the time you get to the Rockies. Even at 100 miles a day, that'll take you 24 days. Your early option of flying on May 26 would then put you at the foot of the Rockies on June 18 at the earliest. There is almost zero chance of Hoosier Pass being snowpacked on June 18, no matter what kind of winter we have.

Unfortunately, Ray got sideswiped by an 18-wheeler in Virginia (see Day 49). If you look at the picture of the road he was on at the time, you can see why it's often better to stick to ACA routes, which likely would not have chosen that road. Ray deviated off the TransAm in Missouri as he was headed east.

One driver out of a thousand will give you problems, but you only hear about the one. Furthermore, that one won't give you that much of a problem. I rode the entire TransAm with no close calls at all, and no visibly irritated motorists.

Routes / Re: Mammouth Caves Loop, Kentucky to Asheville, NC
« on: February 21, 2012, 02:46:57 pm »
I recommend you use Google maps, but don't use the bike route option. The bike route option of Google maps is useful for getting you to the grocery store, but really bad for getting you long distances. It will give you a route with a thousand turns, put you on many unnamed paths that you won't be able to find, and might even route you on hiking trails. Instead, use Google driving directions, but ask for the "Avoid Highways" option. Then look at the roads with street view, and get traffic volumes from the state Departments of Transportation, and adjust as you see fit.

The ACA does not publish a database of usable roads.

Ray Jardine rode it in 2010. Some of the road has no shoulders, and where it does have shoulders, it was "littered with bicycle tire flattening things like chunks glass, sharp rocks, bits of metal falling off cars, and worst of all, the highway cyclist's nemesis: blown truck tire wires. At times I felt like I was pedaling through a minefield."

But worst of all, he hated the rumble strips. No direct link to the page is available, but go to this site, click on "Missouri" and forward two days to Day 39.

Routes / Re: East to West TransAm to Southern Tier

It's interesting to see how different people have different criteria in what makes a good route. While I agree with siden420 on all the advantages of riding on the Interstate (safe, wide shoulders, good cell service, good access to services, good pavement, less distance, less hilly), I nevertheless find it miserable. It has none of the charm and tranquility that motivates me to be out there riding in the first place.

Routes / Re: Start date suggestions for Pacific Coast (north to south)

I did a quick look at the wind rose data for Arcata, California, in section 3 of the five-section route, so roughly in the middle of the route. It does look like the favorable winds continue through September. The most favorable winds appear to be in May, June and July, then slightly abate in intensity in August (but still favorable in direction) and then become a bit more favorable again in September. They begin to get a bit more easterly in October and become decidedly unfavorable in November and stay that way until April.

If you give me a PM when you are about to set off I'd be happy to ride with you out of Greater Seattle.
That's a great offer. I'd appreciate a guide to get me out of the city. My plan is to fly to Seattle sometime in mid-June. I'll contact you when I have more details.
