Gear Talk / Re: Let's talk about Power Banks for Bicycle Touring?
« on: September 30, 2017, 08:58:57 am »
Another thing to consider is that just taking a spare phone battery or two is lighter and smaller than a power bank.  I have found that if you buy them from a battery supplier instead of the phone supplier they can be pretty inexpensive.
A lot of modern smartphones , iphones for one, don't allow battery changes without major disassembly and special tools so field swapping isn't practical.  There are auxiliary external batteries that increase use time but they have limited capacity too.

General Discussion / Re: Posting Images to Forum

Also, Photobucket has become a pay to use hosting site and any previous images posted using it will not show.  There are still free hosting sites out there (I don't know what they are but they are available) so find one of them or pay the Photobucket annual or monthly fee.

I've often wondered how well those "Companions Wanted" listings work out.  I'd screen any applicants very carefully for compatibility and riding style before agreeing to have them join you.  How tolerant are you for each other's food idiosyncrasies?  How rigid a schedule do you want to keep? Do either of you snore? :)  You get the idea.

 A mis-match can ruin the trip for both of you.

Gear Talk / Re: Thoughts on Nashbar Touring bike?
« on: September 03, 2017, 05:50:05 pm »
I can't speak to this particular bike except to say it's specifications are decent for the price.  My past experience with Nashbar's house-branded products has always been good.  They are reliable and very good for the cost.  Not cutting edge but good.

Gear Talk / Re: Dirt touring handlebar setup

I'd like to retain the original suntour components.....
An uphill, against the wind fight.  What's so special about them that newer, better performing components shouldn't be used?   Sun Tour (the REAL Sun Tour, not the current name owner) was a good manufacturer but they have been out of business for many years.

+4  Particularly with the kind of aggressive "Nannyism" the OP reported, the father is more likely to never get a helmet just to show he won't be coerced by an intrusive stranger.   "You catch more flies with honey...." seems to fit here.

Sounds like the OP has his choice; rain or fire.   :-\

Gear Talk / Re: Bike Choice for Bike Tour in Tibet
« on: August 24, 2017, 08:06:48 am »
I'm not sure there is a $500 mountain bike I would trust on a trip like that.  You are likely to spend more time fixing than riding. $500 is about what you should be spending on the wheel set, not the whole bike. I would recommend something like the Surly Troll with 1.75 or 2.0 marathon mondials. You didn't say if you were supported or un-supported. If you are supported you can get away with a more normal mountain bike that may be available at a reasonable price on the used market. Definitely check out adventure cycling.
+1  A $500 mountain bike is going to have a lot of compromises to meet it's price point and you really don't want to be dealing with low line components and wheels in the middle-of-nowhere.  A simple but higher line MTB or "fat tire" bike would be more suitable.  A full suspension bike would be more comfortable but the complexity may cause more problems then it's worth.  A "hard tail" frame is both simpler and lighter and a rigid fork may also be worth the added simplicity.  The Surly Troll is a good example of a simple but suitable better quality bike.

BTW, Mountain bikes come with three different wheel sizes these days: 26" (ISO 559"), 27.5/650B (ISO 584) and 29" (ISO 622, same as 700c road rims).  World wide 26" wheels and tires are much more commonly available and 29" can use a 700c tire.  27.5 is much more uncommon.  A 26" wheel is probably your best choice for where you are going to be.

What's this trip going to cost?  Don't compromise it by taking cheap equipment.

Gear Talk / Re: front gears
« on: August 08, 2017, 10:34:00 am »
1X gearing seems popular with MTB riders since it eliminates the sometimes problematic front derailleur and the wide gaps in gearing aren't that much of an issue off-road.   For road riding the situation is quite different.  Front shifting isn't that difficult or tricky under road conditions, even with a triple, and close gearing is far more appreciated. 

My road bike (not touring) gearing is a 50/39/26 triple crank and a 12x27 10-speed cassette.  My high gear is 112 gear-inches and my low gear is 26 gear-inches which is more than adequate for most road riding and my cassette is a "straight block" from 12T to 17T with small steps below that.

Also keep in mind that you shouldn't mix steel with aluminum if you can help it... One will give up electrons to the other (I don't recall which direction it goes). The end result is that one will weld to the other in the short term, and in the long-term one will actually weaken the other. In construction they make special coated steel nails to use. I had forgotten about this issue of mixing aluminum with steel, but was reminded when I took the bolts off to rearrange the rack for the hitch, and had to break the slight beginnings of a weld to get the bolts off.
Ever hear of anti-seize or just plain grease?  Either will prevent the conditions you are describing? 

Also, even unprotected that aluminum corrosion will not happen very fast unless the bike is wet a great deal of the time.  When you hear of badly stuck seat posts or stems they have usually been neglected for years.

Gear Talk / Re: Racks with child trailer question
« on: August 01, 2017, 10:27:44 am »
Weight is weight and redistributing it from the trailer to the bike won't make climbing any easier.

If you've already been to SF as a tourist and have seen the city, then keep going and avoid the high cost of staying there.  If you decide to stay in the city, look around the Union Square area.  It's  conveniently located and the hotels are "reasonably priced", at least by SF standards, and there are a lot of plain but good restaurants.

Gear Talk / Re: Need help with European bike
« on: July 15, 2017, 07:12:52 pm »
Given the shipping costs both ways for your own bikes and the fact you need to have a bike shop assembled the bikes at the European destination and perhaps packed by them for return to the US, that $1000 rental cost is starting to sound reasonable. 

Gear Talk / Re: Rigidity of S&S Couplers?
« on: July 12, 2017, 08:28:00 am »
The couplers are stiffer and more rigid than the tube they are installed in.  The do not reduce the frame's stiffness or stability at all.  Their only downside is cost and a slight weight penalty.

Gear Talk / Re: Best Brake pads
« on: July 11, 2017, 08:38:43 am »
My impression of the Koolstop salmon was that they worked well even in the wet, but they had enough negatives that I avoid them now.  The negatives based on my observations when I was using them:
  • They tend to squeal more easily so toe in and general setup is fussier
  • They tend to be a little grabby
  • They seemed to wear out rims faster
Adding to my first posting, I've never experienced any of these negatives with Kool Stop Salmons.  My experience is:

1. Installed on good quality caliper brakes (i.e. stiff arms and good pivots) they are completely silent even if installed with no toe-in.  The only noisy brakes I've had were a set of Shimano cantilevers and a set of Avid SD-7 V-brakes that squealed no matter what pads (Shimano, Avid or Kool Stop) or toe-in I used. 

2. Their action is predictable and not at all uneven or "grabby".

3. My rims last extremely well using them.  One bike has over 40,000 miles and the other over 25,000 miles on the same rims which are still in excellent condition. Obviously, these aren't routinely ridden in the rain, which will wear out any rim more quickly no matter what pads are used.
