Frame Option: Custom brake mount

This basically means any kind of mount I make from scratch. The basic frame price includes a standard disc mount on the back of the seatstay. Sometimes, however, there is an opportunity to enhance a design with something special, here are a few examples of brake mounts I've custom fabricated. Each one was specially designed for a specific frame (or fork), prices of custom brake mounts vary depending on the degree of difficulty and time involved.

Frame option: Paragon Slider drop-outs


Frame Option: 1 1/2" Round Drop-outs

These drop-outs can be a solid option for basically any geared bike. They're sturdy, versatile, and can be shaped, if desired, to blend with specific designs.

Frame option: CUSTOM CURVES

Custom curves have become an incredibly popular option on many of my current bikes. I have been able to offer a fairly descent variety, with only a couple different mandrels for a couple of different radius' and tube diameters. However, I am always gradually collecting ways to form tubes of all different shapes and sizes. Because there are no real "hard rules" as far a what I can and can't do, it's difficult to put a definite price on this option. I have it listed as starting at $100 on the price page, but each build has the potential to be totally unique, so I really need to hear what the customer has in mind in order to give an accurate price quote. For most bikes with some kind of custom curves, the additional charge ends up being between $100 - $200 possibly slightly less for something REALLY simple. It is my goal to offer variety to stimulate the customer's imagination so that they in turn can stimulate mine.


The lines of the bare frame above were inspired by a Ritchey "Plexus". That truly was the first frame I saw that made me think about possible ways to manipulate certain ride characteristics by encouraging the frame to flex in specific places with curves.



Another tribute to the Plexus concept (below).





The fork pictured here is a Titanium Blacksheep number.

Frame option: Integrated seatpost clamp



All of the integrated clamps shown here are accompanied by some sort of dropped toptube gusset, but you don't have to have one to get the other. This option is usually fabricated with a sleeve for double wall thickness, making it an excellent choice for added durability needs.
On the "strictly-bling" side of things, the sleeve becomes a canvas for some added expression with shapes, maybe even a hand-carved initial.

Frame option: Split Seattube

The split seattube has become a "signature feature", of sorts for me.
It's a concept I came up with mainly to accommodate a short chainstay, such as 16.5", on a 29er. It allows me to produce virtually any effective seattube angle while giving clearance for the rear tire. This could, of course, be accomplished with a simple bend or notched and welded joint in the seattube. However, some advantages of the split seattube are:
-Greatly improved pedaling stiffness at the bottom bracket -- From the small handful of split seattube customers I have so far, all have made comment of a notable difference. I also have my own ongoing thrash test.
-Seatpost can be lowered ALL the way if desired. This is a huge plus for those seeking a compact cockpit, allowing infinite saddle heights, all appropriate to how ever you want to ride your bike that day, dropped to the rails if you please, or at full leg extension for an all day climb.
-Water cannot enter the frame via the seattube, one less place.
-The short chainstays that generally accompany this design create a 29" wheeled mountain bike that handles exceptionally well on tight switchbacks and riding conditions where the front wheel must be easy to pull up. The shorter, quicker handling wheelbase is "counter balanced" with big wheels and a slack headtube angle, while the improved lateral stiffness of the bottom bracket shell makes the bike more responsive when you're pedaling your hardest.
This is probably my most performance enhancing option.









Frame option: BOX GUSSETS

This is a 3 piece gusset I frequently use to strengthen headtube junctions or for reinforcing seattubes for dropped toptube designs. I call it a box gusset because the inside is hollow, making a stiff structure. Some people have asked if it is just two side plates with the middle filled with brass -- not the case, doing it this way is significantly lighter and reduces the heat affected area.
