It can be done. See http://www.rsf.org.uk/. If you do it on a road bike I recommend for your sandy conditions the widest tires your bike will mount.

dkoloko -- By the way 35s fit on the Open Sport/MA2.  My bike came with Avocet Cross inverted tread 700 x 35s, and I have run Conti touring 700 x35 also with no issue.  It's a size bigger than recommended, but works fine (I did the Pacific Coast with Contis).

I specified 35mm measured. If you are successful mounting 35mm tires (actual measurement), fine. I couldn't mount 35mm Marathon tires on rims, not MA2, but same width, and yes, with hooked beads. There is also question of performance when such size tire is mounted on such size rim.

I have a 15 year old Randonee that came with Mavic MA2 rims.  The rear needs replacement now

So now the question - Do I just get a new Mavic (now Open Sport) and spokes and call it a day, or do I replace both rims?  The reason I ask is that if I am going to do both, I'll switch to A 319s.

I have examined the front rim, and there are none of the micro-cracks Mavic rims are known to develop, but I can feel i slight ridge near the lip, indicating that there is noticable wear on the breaking surfaces. The wheel has been fine, with only minor truing over 15 years and about 25,000 miles, but is that the point of wear out?

So - Those of you with lots of experience:

The MA2s did fine on a loaded Portland to SF trip 15 years ago, but should I really consider stouter wheels for the TransAM? That would tip me to replace both.

Or should I just replace the rear rim?

Personally, I would just replace the one rim. As to stout, MA2 rims should be fine; the build  quality is more important. As you know, MA2 or its successor will limit you to 32mm width tires (actual measurement), which should be adequate, although you may think you need wider rubber. I've found the Open Sport rim easier to build, which also means it should stay true longer. I have not noticed micro cracks on my Mavic rims. Is this something more particular to anodized rims? If I was switching to A319 rims it would be because I want to install wider rubber, not because I thought MA2 rims weren't stout enough to tour.

Routes / Re: Florida

The west coast is, frankly, a lot more scenic and interesting than Florida. If you could do a trip there between Labor Day and mid-October you should have a fine, if physically demanding, tour. This would avoid the summer crowds and the winter storms.

I did 1100 miles of Pacific Coast Route during time you recommend. Still heavy traffic on highways. Scenery is worth it, but traffic is a factor. Also, that time of year number of campgrounds are closed.

Gear Talk / Re: Front Derailleur for Half-Step plus Granny
« on: August 29, 2013, 10:40:54 am »
The simplest way to get half step and the one I'd recommend is to change 40T to 45, and that's all. You will be using the 50 with half step. Whether you lower the 28T chainring to 24 depends on low gearing you need and how it works out for half step. Each shift on front should be half of each shift on the rear.

Anyone have experience with

or

? Or, with both, to compare?

I would not be mounting front panniers.

DK: Irene was late August of 2011. Sandy was October of last year.

You posted correction before I had a chance to. It was an earlier hurricane. I did hole up during tropical storm Irene in NH doing another bicycle trip.

First question if you can get over the pass in Glacier Nat. Park if you follow Going to the Sun Rd. As to the East, I rode Northern Tier New England section in Oct. I encountered torrential rain, hail, snow flurries, hurricane winds, and temperatures down to the 20s.

Was that due to Hurricane Sandy, which is not the norm?

Irene. Which says could be another storm in future.

In addition to my previous comments, add campgrounds closed.

Apparently they are following Google; good for them. Google bicycle routes are still in Beta, meaning you can use them, but expect mistakes. Accordingly, I expect Mapquest to be farther behind with producing optimal bicycle routes. I do not pay much attention to estimated time to bicycle routes.

24 to 39 still seems like a big jump but much less than the 24 to 42 possibility.

I shift from 24 to 49; no problem.

If it were me, I would invest in a mountain bike compact triple crank set and the tools to do the job.  It sounds like the crank would be more that you want to budget, but the tools could be cheaper than what the dealer would charge you to do things.

Why are you advising the author to throw money in the toilet?  Your advice is very expensive compared to changing the chain rings.  The mountain bike triple you recommend can get down to a 22 tooth inner ring.  He currently has a road triple crankset with 130mm bcd for the outer and middle positions and 74mm bcd for the inner ring.  He can put a 24 tooth ring on his current crankset.  There is so little difference between a 22 and 24 inner ring that its not worth talking about. 

I previously advised that the most economically sensible choice is to just change rings, so we agree on that. However, you error in dismissing difference between 22 and 24 ring as "not worth talking about". It is not the two tooth difference, but the percentage difference in gear inches that is determinative. It is significant enough to determine choice.

On a compact triple, aluminum generally is not strong enough for the small chain ring. 

I don't know why should be more a factor with compact triple than with any other triple, but my thousands of miles experience touring with aluminum small chainring says strength is not a question. I suspect most who opt for steel instead of aluminum for small chainring do it for anticipated less tooth wear than for perceived strength.
