A new ride for myself

I haven’t built myself a new frame for over 4 years,I felt no need. But the allure of titanium, some new “standards” and the advent of 29+ got to me. After building the “quiver killer” in my last post, I decided I must have one! So, I built myself one.

Many of the same features exist on this well thought out versatile frame, though mine is decidedly more “trail” and less “tour”.

Tires/wheels: Able to run 29, 29+ and 26×4″fat

Drive train : SS, dingle speed, 1X whatever, Rohloff IGH.

73mm BB shell

44mm head tube

Paragon Rocker dropouts

423mm chain stays, slammed forward (likely 430-35mm with 29+)

Curved and shaped tubes everywhere

Travel limited and tuned Maverick DUC32 for 29+ tires

XO1 crank with North Shore Billet 2x spider. This allows a slightly wider chain-line (tire clearance) and the ability to run a 2nd chain ring in the bash guard position for my preference, a “dingle speed” set up,.

Currently running 29×2.4 until the tire and wheel options I want are available ( Maxxis and Stans 29+). 1X7 (11-24) cassette on a single speed hub with shadow+ and a narrow-wide chain ring. It’s the first real gears I’ve run in a long time. With the trails here still drying out, I haven’t really been able to put it through its paces, but I can tell, I dig the top end speed I’ve been missing.

If you are interested in one this complicated it will set you back $3500


































Titanium 29+/4″fat/Rohloff drive

This one has it all going on:

Titanium 29/29+/4″fat Trail/Bike-packer.

Set up for 1X/SS or Rohloff drive options, all with a standard 73mm BB shell.

44mm head tube

Paragon Rocker dropouts

Curved Seat tube, top tube and seat tubes.

Heavily modified chain stays, curved and ovalized with drive side plate/yoke.

Extra bottle mounts on TT and DT for strapless bag mounting.

With a few sets of wheels, a real quiver killer.

I’ll post photos after it gets (partially) powder coated.




Titanium offerings

In addition to titanium stems and handlebars AMPeirce is now offering Titanium frames! Pricing is still TBD, but will likely start at $2800 and will have all the same options available as steel models, curves, dropouts etc…

Tandem, Moto style!

Set up with custom travel limited Maverick duc32  and Knards.P1010127

Not as pretty as the truss fork, but pretty awesome for keeping the front end under control.

We have been riding the thawing Colorado conditions lately, and thus lots of mixed dry and sticky mud, so far the drive-train is unflappable,mud build up has not been an issue at all. loving it!P1010124

stainless steel butterflys / Indianapolis Zoo project

Well, this is what has been keeping Tammy and I quite busy for the last month. We are working with Banner art studio on a art installation for the Indianapolis Zoo. It is a sizable project that has to be done on deadline for their upcoming butterfly exhibit. The project is comprised of (6) sixteen foot tall “tree” or branch structures each with (2) eight foot butterfly’s perched atop, and then another eleven butterfly’s perched all over the outside of the building. All of the structures, are made of TIG welded stainless steel and all of the coverings are made of sewn fabrics (not printed) of differing weights and colors to create a translucent illuminating effect in sunlight. For a vision of the project see:

Our part of the project is, of course the stainless fabrication. The work is surprisingly much like bike fabrication:

Lots of coped cuts, both mill cut and hand filled… checkP1010068

Lots of TIG welding in compromised positions…… CheckP1010085_1

These butterfly structures are kinda like doing chain-stays, .049 wall 5/8″ diameter SS tube to…. well, OK it’s schedule 40 pipe, but you get the idea.P1010090

The branch sections of the “trees” had to be welded with full structural integrity. That means full penetration, back purged multi-pass welds.P1010070

This is the back-purged root pass on the schedule 80 304L stainless “tree” sections.P1010120

A pile of “trees” getting ready for freight to Indianapolis. Those are 3/4″ thick base plates with gussets, they will not fall down!

Anyone smell slightly cooked fingers? It is fun sometimes to turn up the amps, but I must admit this much of it has worn on me some. Running 200amps for eight hours straight, day after day…..I’ll take the delicate stuff any day. Fortunately what is left to do at this point is relatively light duty…. kinda like head tube top-tube junctions and chain-stays….I tell myself.

AMP in Mountain Flyer Magazine

In September 2010 AMPeirce Cycles was featured in a story on mountain biking in Del Norte, Colorado.  Photographer Kevin Krill was on hand to record the fine escort on the trails and around town meeting locals.
