Gear Talk / Re: Panniers vs. BOB?
« on: September 27, 2014, 06:43:38 pm »
It will be interesting to see how long this thread goes.  Panniers vs Trailer has the same potential for heated discussion and disagreement as Shimano vs Campy and "whats the best chain lube?" questions.

The calculator app should do the trick. Divide the ring teeth by the cog teeth and multiply by your wheel diameter.
That only gives one gear at a time.  The Sheldon Brown "app" gives the entire gear chart.

And another insidious danger is the debris on the side of the road.  You must be very vigilant about this and constantly be scanning the shoulder ahead.
That isn't limited to the Interstates and any road with a shoulder has debris and litter on it.  The auto traffic blows anything on the travel lane over to the shoulder.

Don't forget that the higher the speed differential, the shorter the reaction time.  Even if you see it coming, in front or in the mirror, your ability to evade is reduced.  This one isn't a v-squared problem, but once you've used up your reaction time, what's left over to actually move is a lot less.
Yes, but it is extremely unlikely there will be any problem in front of you since there are no side roads, driveways or drivers coming the other direction turning left in front of you.  Also, from behind, everyone is going the same direction and has multiple lanes to do it in.   The major danger on Interstates is at the entrance/exit ramps and cyclists have to be very aware at these points.

As noted, I would not ride any Interstate through or near a large city, even it it was permitted, as the interchanges are much too close together.

Along with what may be excessive weight on your hands, do you move your hands around while riding?  The major disadvantage of straight bars is that they offer only one hand position.  Adding barend extensions will give you an alternative hand position and avoid constant pressure in one place.  One reason drop bars are popular (beside aerodynamics) is the multiple hand positions they allow.

Try the "Classic and Vintage" forum at bikeforums.net  The posters there should be able to provide all of the details.

General Discussion / Re: Can scooters ride the routes?

Motorized scooters come in a huge range of power and ability these days.  The slow, smoky two-stroke Vespas of the past have been replaced with similar, low power 4-stroke models with a top speed of maybe 35 - 40 mph up to 650cc 30+ HP models with top speeds near 100 mph.   "Slow" doesn't mean what it used to.

General Discussion / Re: What is a century?
« on: September 08, 2014, 09:15:10 am »
I think the functional definition of a bicycle century is 100 miles in "one day", typically from morning until evening. Normally not a 24 hour day but you could claim you road a century even if it took the entire 24 hours.

AWOL is the current line of Specialized adventure bicycles.
OK, thanks for the update.  I really don't follow the various manufacturer's product line and name changes from year to year so that's why the name was new to me.

I've never heard of "AWOL" bikes but you absolutely must buy a bike from a decent bike shop or REI, NOT from a department store or Xmart.  Trek, Specialized, Cannondale, Fuji, or other well established brands and REI's house brand should all be available in the type you need and be reliable.

As Pat recommended, go to a shop that will fit you properly and is willing to make changes to dial in the correct dimensions.  A touring or similar bike will be far more suitable than an ultralight carbon frame racing bike.

Finally, ride quite a bit before embarking on your trip.  You need to get used to hours in the saddle and to handle the bike.

General Discussion / Re: Quick fixes for cyclist's palsy?
« on: August 30, 2014, 05:47:11 pm »
I don't know your handlebar set-up but simply getting drop bars and riding on the hoods solved all of my hand numbness issues. I like oversized 31.8 diameter bars with flat tops. I use gel pads and Cinelli cork/gel tape to the give the bars a cushy feel. Works great.
The advantage to drop bars isn't the ability to ride on the hoods, it's the ability to have several hand placements so the nerves aren't subject to pressure all in one place.  You can ride with your hands on the hoods, on the tops or on the drops and give your hands a variety of pressure points.

The real "cure" for handlebar palsy is not to get it in the first place.  Move your hands to various positions as you ride.

Also, those "Dura Ace" barends are intended more for time trial bikes aero bars than for touring use.  Again, Dura Ace isn't bought by tourists.

We have three touring bikes in the house with Shimano SL-BS77 Dura-Ace 7700 Bar End Shifters (9 speed), one of which just got upgraded to 9 speed this year.  Bruce Gordon used them on his bikes for years, I don't know what he is using currently.  The shifters work very well on our touring bikes (22-32-44, 11-32).  I don't have any experience with the 10 speed version.
You are not the main market for Shimano's 9 and 10-speed barends.  Yes they work fine and are suitable for your use but if it had to rely on the touring market, Shimano would have dropped them long ago.

Unfortunately Shimano no longer makes triples, but they do make Dura Ace bar end (showing Dura Ace is not only race componentry). So to me that suggests the the newer gear with thinner chains was not up to touring (hopefully just yet), and they will some day. Maybe just a pipe dream, but I may wish to buy another touring bike and sure would like Dura Ace.
Shimano does indeed make triples, they just don't make them in groups their experiences tells them don't sell to tourists.   The 105 FC-5703 is a triple and has a 74 mm BCD for the granny ring so it will take down to a 24T chainring and several of their MTB and Trekking cranks are available as suitable triples.  Also, those "Dura Ace" barends are intended more for time trial bikes aero bars than for touring use.  Again, Dura Ace isn't bought by tourists.

Gear Talk / Re: trikes
« on: August 28, 2014, 01:02:29 pm »
Then there are many, many designs of standard upright trikes,which have been a part of the cycling world for 125 years now.  They sit about the same height as standard upright bicycles.
Yes, I've seen them as parts getters in industrial plants and for shopping transportation in retirement communities but i've never seen on on the road.  A combination of weight and odd handling and limited cornering ability are major disadvantages.

As mentioned, my first choice is the Surly...and although they have their frames manufactured in Taiwan, I would also like to do business with a NA outfit if possible...
Wait a minute. This whole thread started when you asked about a frame made in China and sold directly from Chinese based supplier and then you say the above?  Excuses me if I'm puzzled. 

Surly is owned and sold by QBP, a US based company, so if you want to deal with a NA based company that's about as close as it gets.
