Sometimes it seems a bit daft (but then, who am I to say?):

But sometimes it's just the right tool:

General Discussion / Re: Riding on the US Interstates

The issue is riding on an interstate with its wide shoulders, with two lanes giving trucks a lane to pass and of course with no oncoming traffic must be safer.

Many (most?) bridges on the interstate system do not have shoulders.

Being caught and passed by two side-by-side semi-trailer trucks on a shoulderless interstate bridge was memorable.

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.

Click on some of the above links for lightweight racing versions.

Trikes 'oddly handlinng and limitedly cornering' at a rainy world championship a few years back.

Well, who doesn't love trikes, trikes, trikes, trikes, trikes, trikes, trikes, trikes, trikes, trikes, trikes and trikes?


You can check out this

http://youtu.be/qbv0FrfF67U?t=2m20s

video to see how much lower common tadpole recumbent trikes are than a representative recumbent bike.

Some other recumbent trikes sit higher, like the TerraTrike Rover, the Greenspeed Anura and others.

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.

Trikes make up such a fractional percentage of pedal cycles on the road that I'm skeptical a meaningful empirical analysis could be done on their relative safety.

Best,

Some riders love their saddles so much, they name their children Brooks.  That's cool, but Brooks isn't the only tensioned leather saddle in town.

Brooks


Persons
Selle Anatomica
Berthoud
Tops
Selle Monte Grappa


Gyes
Cardiff, made by Gyes
Velo Orange, made by Gyes
Zimbale, made by Gyes
Origin 8, made by Gyes


Torelli
Dia Compe
Spa
Papillionaire
Rivet

Lepper (out of business?)
Ideale - definitely out of business



No connection to any retailers mentioned, examples only.  There are plenty of places to get any of these.


(I suspect the Torelli, Dia Compe, Spa, Papillionaire and Rivet saddles are also manufactured to specification by Gyes.)

I started riding tensioned leather saddles in 1979 and have since.  I currently own, ride and like my Brooks Pro,  two Persons #77 Deluxes, a Selle Anatomica Titanico NSX Watershed (NOT a split saddle, unlike other Selle Anatomica models) and a Gyes GS17A.  I'm unimpressed with the construction of the lower frame of the Tops tensioned leather saddle I have.

PS - Please don't name your child Selle Anatomica.

Opine me... Are the chain stays too short for rear saddlebags?

The Troll's 16.5" factory geometry chainstay length is measured to the shortest point on those long track ends.  The rear rack attachment 'eyelet' ~looks~ to be maybe another 1.25" further back.

I remember the Schwinn Varsity having a fillet-brazed steel frame, but those fillets were absolutely huge-- very thick.

Your memory is faulty on this.  The Varsity had an "electro-forged" (electric arc welded) frame, an entirely different technology.  What you mistakenly thought were "absolutely huge" fillets were actually just radii in sheet metal stampings.  See:

http://www.sheldonbrown.com/varsity.html

Schwinn did make other frames with the fillet-brazing method, as have many other companies down through the years.  My 29 year old Santana tandem has a fillet-brazed frame with delicate, small radius fillets, and it's held up perfectly for ten of thousands of miles.  Some Jack Taylor fillet-brazed tandems are approaching 70 years old and still being ridden.

Wow, from out of the depths of the archives.

None of the steel bikes mentioned in this thread (Co-Motion Americano and Pangea and Surly Long Haul) are brazed lugged steel frames.  All are TIG welded frames.  No brazing on them.  No lugs.  If a TIG welded frame breaks, you will have to weld it back together, not braze it.

BTW, this is absolutely not true.  There are no alloys or grades of steel that can be welded that cannot also be brazed.  One can, and for the last 120 years many have, brazed bicycle frames without lugs (it's called fillet brazing). 

But of course, we're not really talking about the possibility of a third-world blacksmith reassembling a frame that's come completely apart at all it's joints (although that is an amusing thought).  We're here talking about repairing something like a frame crack.  On a RTW steel bike like the mentioned Co-Motion Americano and Pangea and Surly Long Haul Trucker: clean the paint back, drill a small hole at either end of the crack to eliminate the stress risers, and then brass braze it.  Low-tech & done in villages all over the world.

Gear Talk / Re: Brifters vs. bar-end from a convenience standpoint

You are correct that neither Campagnolo or SRAM are in the touring business...

Unlike Shimano, SRAM actually has a purpose-marketed touring (they call it 'trekking") line in their Via groupsets.  Additionally, and like Shimano, a nice all-SRAM touring drivetrain could be put together mixing their road, mountain and Truvativ lines.

One could also put together complete single-brand Microshift or SunRace Sturmey-Archer touring drivetrains.

Gear Talk / Re: Could a cyclo-cross bike do?
« on: October 11, 2011, 07:53:32 am »
1) I don't think you need another bike for weekend and week long tours.  I think your present Trek FX7.5 is fine for that - certainly as good as a repurposed cyclocross bike.

2) A "real" touring bike will serve wonderfully for fitness and general riding when you're not touring - certainly as good as a repurposed cyclocross bike.

3) If you've got a jones for a cyclocross bike, get yourself one.

I will never understand this fascination with boiling water.

Boiling water is the kingpin of food preparation in modern backpacking, due to the heavy reliance on reconstituting dehydrated foodstuffs.  Modern backpacking camp-kitchen equipment has become optimized for this, and it's a significant performance parameter for backpackers.

For cycletourists, not so much.  I remember mentoring an experienced backpacker about to take her first weeklong cycle tour.  "But you don't need to pack a week's worth of dehydrated food!  You'll be riding past stores a couple times a day.  Buy fresh as you need it!"  to which she replied, "How will I cook fresh food with my Jetboil?"

Here's a thought:  your foodstuffs, your recipes, your cooking gear [pot(s)/pan(s) & etc.] and your stove work optimally as an integrated system.

Try replacing your Conti T&Cs with tires like the Schwalbe Kojak folding, Avocet FasGrip City Carbon 12, Specialized FatBoy or Continental SportContact, all in the 32/35mm width.  All have finer carcass construction, much lighter weights and smoother treads than your present Conti Town+Country tires.  And mate them with some quality, light tubes like the Maxxis Flyweight.

I see very little chance of slipping due to the tooth configuration of the belt, which would also eliminate excessive tension on the belt/ bottom bracket.

But many, many reports on the 'net from users indicate the toothed belts do slip w/o quite high tension.

Here's a widely available, lightweight, modern chaincase.
