Gear Talk / Tandem crankarm length

Craig,

If you are going to change the rear cranks, you might want to go for 165 for your daughter.

As for gearing, whether the 28 tooth cog gives a low enough gear depends on the size of your little chainring.  Personally I would recommend you have at least a 22 inch low.

We rode the Southern Tier on our tandem (self-contained) and with a low gear of 20 inches (a 20 tooth granny and a 27 tooth big cassette).  It was adequate, but when we headed to Colorado we switched to a 17 inch low gear (20 front / 32 rear).  I think we will stay there.  Our setup is 48/38/20 chainrings and 12-32 cassette.

Fred,

I just discovered that ACA had the GPS coordinates available.  Thanks for all the work!  We are planning to ride from Ohio to Maine on the Northern Tier this year, and were planning to take our Garmin Etrex Vista (we have MapSource 4.13) along.  We were on a trip last year with someone who was using a GPS unit - we particularly liked knowing the total ascent numbers through the mountains.

The website says we should check back in Spring 2004 for Northern Tier GPS data.  Do you know when that will be available?

Is there anything special we should know about loading the data?  I have uploaded maps from MapSource with no problems, but I have never worked with waypoint files.  I have printed the 7 page pdf file.
