General Discussion / Re: Miles Per Day
« on: March 19, 2014, 05:37:40 am »
That mileage of 60+/- per day seems like a general consensus of all of the travel articles I've read too and seems like a worthwhile distance to plan around. Even at only a 12mph average that only 5 hours/day on the bike and leaves plenty of time for sightseeing, photography, meals and just lazing around.

You can do less on a day with rain and/or headwinds and more if the conditions are favorable and there is nothing worth stopping for but 60 is a good average.  You will read about those who do 100+ miles a day every day but that seems to be an intent to just ride, not tour. 

Either way, tell the mechanics at REI what you're going to be doing with the bike, and ask them to check it over thoroughly.  I've had new wheels on a Randonnee start breaking spokes within 1,000 miles, and another set of wheels that they checked over now has over 12,000 miles with no broken spokes (that I can remember).
+1.  Unevenly and inadequately tensioned spokes are epidemic on new bikes and lead to premature breakage.  Have the REI mechanic check and, if needed, improve the spoke tension and trueness.  Done properly you should almost never break a good quality spoke if you don't mechanically damage it.

Also, remember neither bike comes with pedals so leave a few dollars in your budget to add them.

Thanks DaveB! I understand you can not convert an existing quill fork to thread less. I have a thread less suspension fork on another bike I was thinking of using. When I installed it I did not cut it down so I have plenty of material to work with. My question was I guess is can you replace the existing pressed in bearings with a thread less bearing set into the headset.
Assuming the new fork's steerer is the same diameter as the old one, yes you can certainly replace a threaded headset with a threadless one and then use the threadless fork.  It's an easy conversion and done frequently.  You will need a suitable new stem and spacers but otherwise it's very doable.

One caveat; the new fork may not play well with the bike's geometry is it's axle-to-crown length is significantly different from the old fork. 

The differences are pretty major. 

The Rondonee is a drop bar dedicated touring bike and pretty much a duplicate of other well regarded bikes like the Trek 520 and Surly LHT.   It has barend shifters, appropriate gearing and proper sized road tires.

The Safari is more of a Hybrid with moustache bars, MTB components and wider and heavier tires. 

So, it you are used to or prefer drop bars and plan on little off-road use, get the Randonee.  If you expect to ride on a lot of unimproved roads or trails, the Safari is more suited. 

The Rondanee is more expensive but, to my thinking, the extra money is well spent and it would be my choice for a long road tour.

Tthreaded forks cannot be converted to threadless.  Even if there is enough extra length to accept the stem clamp, the threaded section is too weak to take the forces.  To go threadless you need a new fork, headset and stem. 

A work-around is to use a quill adapter in your current threaded fork.  These are a straight quill that goes into the steerer like a quill stem but then accepts a threadless stem. These allow you to use either a 1" or 1-1/8" stem and the newer 31.8 mm diameter handlebars. 

Here is one:

Converting a 7-speed to an 8/9/10-speed requires a new freehub body (8/9/10-speed is wider), removing some spacers from the non-drive side, recentering the axle and redishing the rim to center it properly.  I believe your 970 has either 130 mm or 135 mm dropout spacing and your current hub matches it so you won't have to spread the stays.  Of course along with the new freehub body, you will need matching shifters, cassette and chain so this can be a relatively expensive conversion.

One time to definitely get out of the rain is during an electrical storm.  Find a suitable shelter (NOT under a tree) and wait it out.  Wet is one thing, fried is quite another.

Gear Talk / Re: 9spd-10spd chains
« on: February 27, 2014, 07:24:53 pm »
The only time I have broken a chain was the result of seeing how high a gear I could climb a hill with while carrying a load.  In other words, testosterone overload more than likely.  Since that side of the road debacle I have learned to use lower gears and preserve my chains.  I have never broken a chain since.
Even at that did the sideplate crack or did you just pull out a pin?  Most chain failures are from improperly installed special joining pins or, more commonly, from reusing a standard pin on a narrow (8-speed and above) chain.  Sideplate failures are very rare and usually are the result of corrosion or chemical attack from poor cleaning methods.

I certainly agree with staehpj1 that more chains are ruined by aggressive cleaning methods than by neglect.  Particularly harmful is soaking the chain in water based degreaser.  Unless you thoroughly rinse out all of the detergent and completely dry ALL of the water out of the interior the new chainlube will never go where it's needed.

Danno, well, they made us Chemical Engineers sit through a EE service course so I'm sympathetic.  I never did understand why you guys needed i.

Anyway, I looked up the heat treating of some typical Cr-Mo alloys and found this:

"4130 (and most of the other low alloy steels) may be annealed at 1550 F for a time long enough to allow thorough heating of the section size."

So I expect baking at even 400°F to fuse a powder coat won't do any harm. In fact, many factory and most custom steel frames are powder coated these days.

Comfort? Upright?
Look at recumbents. Heads up, high def cycling. Designed with the behind in mind.
Fortunately for me, it takes a certain kind individual who has the courage and will take the opportunity to test ride a loaded recumbent.
I don't think that two people coming here on a tight schedule for a long trip without any previous recumbent experience should use this opportunity to find out if a recumbent is for them.

A suspension fork is a real negative on a road touring bike.  It adds a lot of weight and is totally unnecessary.  A rigid fork hardtail hybrid would be far more suitable if you really want flat bars for extended days.

Allowing $100/day for everything (hotels, camping, food, etc.), based on your schedule, a 60 day trip will cost you $6000.

Do you actually ever spend that much per day on a multi-week or multi-month tour?
Well, the OP is traveling alone and planning on hotels a couple of days a week and that implies eating most meals out.  Between hotels, camping fees and meals, I don't think my estimate is too far off.  And yes, a 60 day schedule is pretty tight and demanding so, if it's 80 days instead and only $75/day it's still $6000. 

So, his $2000 for the entire trip is $33/day for 60 days or $25/day for 80 days and that won't come close to covering what he proposes.

.  The only detail you should be aware of is the temp you can bake your frame without altering its metalurgical properties. 

 As for swapping parts around and upgrading your bike, many of us do it.  Once you become a competent mechanic, you will do all sorts of swaps that you could never afford to have a bike store do.
The 970 was a welded steel frame so no reasonable baking temperature is going to harm it.   

Note that building a bike up from a bare frame is the most expensive way possible to get a custom bike unless you have a big supply of parts already on your shelves and can do all of the work yourself.  Buying your components at retail and having a shop do the work will be far more expensive than starting with a suitable used, or even new, bike.  That said, if the cost isn't a big issue, it can be a very rewarding way to get just what you want.  Even more rewarding if you can do the work yourself.

I doubt they will specifically know about Adventure Cycling but just say you are going to bicycle routes mapped by a USA cycling organization and give them a rough idea of what you want to do. They really don't care about the specifics of where you will be, only the time frame. 

General Discussion / Re: "Protection" necessary?

A hunter took a shot at me on highway 395 I saw it hit the rock face but decided not to hang around and find the bullet.
Are you sure you weren't a bit too near a meth lab or a pot field?  Those people are rather protective of their "crops" and California has lots of them.
