General Discussion / Re: Gators in FL
« on: August 27, 2010, 07:23:11 pm »
One place to avoid in Florida is Gainesville.  There are at least 40,000 Gators there during the school year and they can be VERY annoying, particularly on foootball weekends.  :D

Gear Talk / Re: 28'' tubes?
« on: August 19, 2010, 08:24:36 pm »
The shop in Orlando didn't really have 28" tubes, he just recognized what you really needed.  Quoting from Sheldon Brown's web site about 700c (ISO 622) wheels; "In northern Europe, this size sometimes called "28 inch.""

Just to make things even more confusing the current MTB wheels advertised as 29" are also a 700c rims and tires.

Gear Talk / Re: Lower gearing: change cassette, chainrings or both?

Check out Harris Cyclery's web site under "9-speed cassettes".  They offer 12x32 cassettes in XT and SLX level called "The Big Dozen" and a really wide 12x36 9-speed from the SLX group.  Their prices are reasonable.   They also offer a 13x34 "Cyclotourist 13" cassette but this one is a bit pricey.

In the past I believe the 12x32 and 12x34 9-speed cassettes were only available in XTR form with the largest few cogs made of Ti and the cost was eyepopping.

Your post, which is purely anecdotal, indicates you might have packed your mass incorrectly and contributed to your difficulty handling your bike at speed--another excellent reason for reducing one's traveling kit.
Please reread what I wrote. No, I did not "pack.... incorrectly" and I never said the bike's handling was difficult or unstable.  It wasn't and we were touring in both the Finger Lakes of NY and in Central PA, both of which have long difficult climbs and screaming downhills.   The bike was predictable and stable at all times. 

What I did say was that the extra weight, although relatively a low amount,  was noticable in the increased effort it took to both climb and accelerate the loaded bike compared to the bare bike and my statement was intended to counter the posting that implied that extra weight wasn't significant.

Our Cannondales came with 30-42-52 cranksets, and  11-32 cassettes.
I've never understood why any touring bike would come with an 11T cog and a road triple crank.  No touring rider has any need for a 127" high gear and the 30T granny doesn't provide a low enough low gear with any reasonable big cog. 

I suppose they just use what's readily available from the component makers and let the buyer sort out the problems.   Trek seems to provide better OEM gearing on the 520 and, of course the small specialty makers (Co-Motion and similar) do provide more useful gearing but it's not as common as it should be.

I hate to be the bearer of bad news, but Cannondale will be dropping the touring bike from their 2011 lineup.  Perhaps the value of the bike will be going up!
Well, the OP's bike is just an early MTB so it's collector's value is pretty much nil.

General Discussion / Re: Question about airplane travel!!?
« on: August 14, 2010, 08:18:57 am »
+1 on checking the airlines own web sites also.  BTW, be careful comparing ticket prices.  Some sites list only the bare ticket cost and only later do you see all of the "extras" (taxes, TSA surcharge, etc.) added in.  Others give you the full cost up front so be sure your comparisons are on the same basis.

I discovered this earlier this year when I was booking flights to Europe.  I got what seemed to be a decent price from one of the travel web sites and then a much lower price from another.  It took a bit of study to realize the lower price was quoted without all of the extras and when they were added in the "lower cost ticket" was actually slightly higher.

Be careful how much you add to the bike box.  Southwest is pretty reasonable but they, like all the others, have a weight limit and the overweight charges can be pretty eyepopping.  I believe the maximum is 50 pounds but check with SW.

General Discussion / Re: Shipping a bike through REI
« on: August 10, 2010, 06:54:43 pm »
I just checked with my REI in Santa Monica and they charge $93 (to ship to Minneapolis REI) insurance, bike box $10, having them box it up $35, and bike re-assembly would all be extra. Hmmm... still a bargain?
Check shipping costs with Fed Ex and UPS and see if it's a bargain.  Of course neither of them will box or reassemble the bike for you.

Gear Talk / Re: Gunnar frames - are they any good????
« on: August 09, 2010, 07:54:36 am »
Along with the Gunner look at Co-Motion's touring bikes as they are very experienced with S&S couplers. Another experienced S&S builder is builder is Bilenky.

Gunner frames are made by Waterford Cycles and are very highly thought of. Here is the Sheldon Brown/Harris Cyclery web site description of them:

I have ridden an number of crushed limestone trails.  It is cheaper than blacktop, but the rolling resistance is higher and I don't know how that affects you ADA requirements.  Runoff does not seem to be an issue.
Not only is the rolling resistance higher, but it can be dusty when dry, which is not friendly to drive trains.  And it is susceptible to washouts - a preventable issue with adequate engineering of ditches and culverts.   On the good side, any of these softer trail materials are more forgiving too tree roots that pass beneath them than asphalt which produces  tell-tale cracks and bumps.
I have ridden both the trails mentioned above and agree that the crushed limestone surface, while "environmentally friendly", does have it's drawbacks.  It's rolling resistance is noticably higher than any blacktop surface, particularly when wet, and it is really dusty in the dry. 

It can be ridden on road tires and I have used a street bike with 700x23 tires but wider Hybrid or semi-slick MTB tires work a lot better. As to wheelchairs, I think it would be very difficult for them and I wouldn't want to have to push one more than a very short distance on such a surface.

OK, group, what have I forgotten?

Fred
Brake and shift cable housings and cables.  Are the cable wires rusted or frayed?  Are the housings dirty or cracked?  If they haven't been replaced in a long time or are in poor shape, replace them all. 

Be sure to use lined housings and pay the slight extra for stainless steel cables for their smoothness and corrosion resistance.

Additionally, you've got to a wee bit of math. Your total mass––you, bike, water, food, gear, clothing, tools, spares, everything--must be objectively measured before you begin going ultralight. Say your total moving mass at the moment is 250 pounds. Whittling away a whopping 10 pounds is a mere 4% reduction in your total mass! (240/250=96/100)
Those ten pounds don't gain you anything you can feel in your legs
By your logic then, adding another 20 pounds to the OP's load would also be an "insignificant" difference.

Like staehpj1 my experience doesn't support this at all.  On a recent credit-card trip I carried only 13 additional pounds on the bike including the rack, panniers and my clothing and extras.  The weight difference was VERY noticable and completely changed both the handling of the bike and the effort needed to climb the hills on route.  That 13 pounds only represented 6.5% of the entire system (the bike + me + the load) weight. 

Also, when I took off the loaded panniers (~12 pounds total) at the motel to ride the unloaded bike to dinner, etc. in the evening, the improvement in performance was very obvious.

It great that everything works well for you with the revised gears.  What you have now is pretty much box stock gearing for a mountain bike and it should work very well for loaded touring.   

I expect your next bike will have a 9-speed cassette and shifters (since 8-speed is pretty much obsolete) but you can have exactly the same gear range and just three more usable gears in the middle.
