===== Wilderness Trail Bikes =====

WTB was founded in 1982 by a team of OG Marin builders: Steve Potts, Charlie Cunningham and Mark Slate((Lance Wyeth was a fourth co-founder in WTB, who left the partnership in 1984.  Lance coined the WTB name as per: [[https://singletrackworld.com/forum/topic/wtb-do-you-know-how-the-company-name-came-about/|singletrackworld]].))  Together they would put their WTB imprint on millions of components and only a very few bicycles.  In fact, WTB has not officially made a complete bike in the 40+ years of their continuing existence.
Many of Potts and Cunningham branded bike builds have been showcases of WTB components and their WTB collective effort, which will be highlighted in the timeline.  A few bicycles bear the WTB logo and were sold as frames or were one-offs, such as the Swift (1984-5), WTB/Trek (1987), Wildcat (1988) and Bon Tempe (1997-2001).  Their most famous bike, the Phoenix (1991-1998), was sold as a frameset only.
\\

This WTB timeline will also pull in some associational MTBs, such as Mark Slate's individual efforts, which have no room elsewhere in the timeline.
\\

[[potts:start|Steve Potts]] started making mountain bikes in 1981 and soon partnered with [[https://mmbhof.org/mark-slate/|Mark Slate]], who helped build most Potts bikes starting from frame #6.  [[cc:start|Charlie Cunningham]] was another local Marin bike builder who was famously innovative despite a annual output of only a dozen bikes.  Wilderness Trail Bikes (WTB) was founded to market components which each had developed separately while continuing to sell their own lines of bikes.

<blockquote>
The running joke has been "Where’s the Bike?"  WTB sold frames for a period of time, but has never produced a complete bike.

Potts and Cunningham left WTB in 2000 ((Potts states that he left in 2000.  WTB gives a date of 2002.))  Patrick Seidler, the current WTB president, joined in 1988.  Mark Slate continues to work for WTB as their director of product design.

\\

WTB and their founders are collectively responsible for pioneering the following((List condensed from WTB's 1998 catalog.)):

  * The first use of toe clips on mountain bikes
  * Welded aluminum mountain bike frames
  * The original Speedmaster Roller-Cam Brake
  * 135mm rear wheel.
  * Rear hubs with 136mm rear dropout spacing with zero dish, and extra-wide front hubs with easily replaceable cartridge bearings
  * Toggle brakes for mountain bikes
  * Sloping aluminum top tube and large diameter seatpost
  * The Grease Guard bicycle component system
  * The original one-piece fork blade drawings which resulted in the Unicrown((Name coined by Charlie Kelly.  See: [[https://www.mtbr.com/threads/wtb-swift.768653/|mtbr]])) and Unifork
  * LD or Gooseneck stems for dropbars
  * Flared or Drop-style bars for mountain bikes
  * Chain guide and slap protector for mountain bikes
  * Toe Flips for quick and easy toe clip entry
  * Rear drop out with 45° slots and super strong derailleur hanger
  * Alloy single-strut stems for mountain bikes
  * Designs for Araya indicating the basic design and shape of the first modular section mountain bike rim, the RM-20
  * In-line cable adjusters for mountain bikes
  * Rubber chainstay protectors
  * Tire pumps mounted inside the seat post
  * Thumb shifter mounts for drop bars
  * Design of the Specialized line of off-road tires, including the Ground Control tire (named by Jacquie Phelan, wife of Charlie Cunningham)

===== 1982 Roller Cams =====
One of the first WTB products to make it to market and eventual licensing to SunTour were Charlie Cunningham's roller cam brakes, designed in 1982 and featured on all WTB bikes until the late 90's.

<div column 50% #s1986>

===== 1986 Swift =====
Swifts were a Potts & Slate production to produce a lower cost MTB employing only a limited number of WTB components.  They weren't branded with Potts badges and some have WTB decals, perhaps later placed there by enthusiastic owners.  Does this belong in a WTB timeline?  Well, as they were only made for a year or two, and there's no room in the Potts timeline...
\\

SunTour XC rear (1984-5), ARX front (1981-83), TIG welded with a fillet brazed head tube, (early 4-bolt Potts) stem and fork and SunTour? roller-cams (licensed from Cunningham/WTB).  SunTour parts were used instead of available WTBs to keep costs down.  Pressed in bearings with a possible Phil Wood spindle. The Swift was an attempt to make a low cost Potts but //"because they were perfectionists, the Swift ended up being just as much as a Potts."//  Only 42 Swifts were made((Charlie Kelly states that 42 Swift frames were made in [[https://www.mtbr.com/threads/wtb-swift.768653/|mtbr]].))

\\
The parts say 1984-5, but the documentation says Swifts were made from 1986 -> 1987.  Perhaps old parts were used to lower costs?

Jacqui Phelan's personal ride.  Drop bars, single speed & pink((With three consecutive NORBA championships (1983-85) and four years on the US national team (1990-93), if Jacqui rides a drop bar single speed then it qualifies as a mountain bike.))
