===== Interloc Racing Design =====


Interloc Racing Design was started by Rodney David Moses and Paul Thomasberg((Rod states that Paul is a co-founder on [[https://www.facebook.com/photo/?fbid=6867061746668988&set=a.102842539757643|facebook]].)) in 1984 in Winter, CA.((Interestingly, Rod grew up 1.7 miles from where [[https://www.mtbtimeline.com/|mtbtimeline]] currently resides.  Which is roughly 10 miles from where [[ritchey:start|Tom Ritchey]] and [[klein:start|Gary Klein]] grew up in Palo Alto.  Or just 4 miles from [[https://en.wikipedia.org/wiki/Russ_Mahon|Russ Mahon]] of Cupertino, the founder of the [[prehist:start#mdc|Morrow Dirt Club]].  Palo Alto was merely one of many MTB loci, including Fairfax, CA, Santa Cruz, CA, Crested Butte, CO, and Bellingham, WA.  Time for a map?)).  Bicycle frames were introduced the same year, initially designed by [[ https://mmbhof.org/mountain-bike-hall-of-fame/2004/paul-thomasberg/|Paul Thomasberg]] and later a combination of Rod and Raymond Baldwin, after relocating to Oregon in 1987.
  
IRD was mostly known for well crafted bike components, including:
  * **1984**: Interloc seatpost.
  * **1984**: Infinity Taper Wall handlebars.
  * **1985**: Center Pull Progressive brakes.
  * **1985**: Macaroni stems.
  * **1987**: Rotary Brake: a half roller-cam, half u-brake.
  * **1988**: Remote Quick Release: turned a [[tech:post|Hite-Rite]] into a modern dropper post.
  * **1988**: Expedition Fork - no welds anywhere - just a bolted crown and brakes.
  * **1988**: Long Pedals cranks: 195-225mm (!!)
  * **1989**: Switchhback cantilevers.
  * **1990**: Shock Fork and an accompaning full suspension frame.
  * **1990**: Widget Brake: one of the first linear-pull/v-brakes.
  * **1993**: One of the first shock brake stiffeners for wet-noodle RockShoxs.
  * **1996**: Anti-Dive trailing link shock fork.
  * **2000**: Metex Stainless Steel tubing bike - many years before Reynolds 953 and Columbus XCr.

IRD was well known for these and more components, but their frames are relatively rare, with no drive side shots of a 1987 being available, which is when they started production in earnest.  IRD MTBs typically were built for climbing, with steep angles, short chainstays, long top tubes and very tall bottom brackets.
  
1993 is the likely last year for standard IRD frames, as that's when Ray Baldwin, the principal frame maker from 1987 -> 1993, retired.

===== 1985 MTB =====

Frame by Paul Thomasberg.  Josiah((Currently a veterinary doctor in Oregon: [[https://evc.vet/staff/dr-josiah-moses/]].)) by Rod & Belinda Moses.  Unknown components.  Likely a Koski rollercam fork, as Koski's were later spec'ed on all of their first MTBs.
Also likely a 1985, rather than 1984 as the photo states, as other IRD sources suggest they didn't get going until 1985.
