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.

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.

Here are a couple examples of this option, they are simply reinforcements with a decorative touch. Particularly a good idea on mountain bikes that will be ridden hard, they also minimize distortion caused by welding. Both versions are the same price.

Katie had an adventurous weekend of camping at the lake with us which left her looking nearly dread-locked. After about an hour of brushing and several handfuls of hair I had her in a rare moment of almost perfect hygiene so I took some quick pictures before she rolled around in the grass again. She's 2 now and starting to act a little bit grown up, she has been listening - sometimes.

I've had a few people inquire about Wolfhound road bikes lately. Some aren't even aware that I make road bikes because there currently aren't any shown in the gallery of the main site. So I thought it was high time to post a few "Road-hounds".
This is Vern Niehaus' bike. Vern is a local fellow who needed a large, stiff frame to replace a Ti set up that kept dropping the chain due to frame flex under hard pedaling.
