IRD Timeline (From the IRD web site)

 

Interloc Racing Design has created components that have been considered on the forefront of mountain bike design. Mountain Bike Magazine called its products the "best of good old' American innovation and craftsmanship." That's quite a hefty complement, but if you know IRD's history, you know the company has earned every bit of it.

Pioneering functional ideas is what has kept a small company like Interloc going for as long as it has. A reputation for craftsmanship that has been built through word-of-mouth (and not slick ads) has surely helped also.

Originally located in Winters, California and formerly located in Oregon, now we are back in beautiful Northern California where bicycles and good ideas seem to find each other quite often.

Currently we see ourselves creating high quality components and frames for racers and hard-core riders of the mountain and the asphalt. Whatever strikes us as being a true need of the cyclist, you can count on us to look into it

1984
- A pro mountain bike racer came to IRD's machine shop to get a custom seat post made. From that one post, IRD starts getting orders from other racers and IRD was sucked into the business of making bike parts. Different forms of his two-bolt design (by other makers) is a still on the market today.


 1985 - Developed the Progressive Brake. Shimano released a similar brake around the same time (the U-brake)
- First taper wall aluminum MTB handlebar developed


1988
- Developed the Rotary BrakeWidget Brake
This half-U / half roller-cam brake was rated the highest in Mountain Bike Magazine's 1992 test of 22 MTB brakes in wet and dry stopping power.

- Developed Remote Seat Quick Release

- Started playing with frame design; eventually developed the Stoker and Semi-Stoker frame which had a longer front-center, which was extremely comfortable on extended climbs

1989
- Press release for the remote seat binder release.

 

1991
- Developed world's first low-forward pivot full suspension frame

Developed the Widget brake, because they needed a brake that could mount to the rear swing arm. This and the Marinovative Brake are the progenitor to today's V-brakes.
 Anti-Dive Fork

September 1992 press release for the full suspension frame.

1996
- IRD works with Dave Ijams and John Castellano to bring their Trailing Link Fork to life. This was the first production fork with an Anti-Dive feature
 

2000
- IRD gets back into the frame market with Metax stainless steel frames. It was hard to get a consistent supply of Metax, so the project was scrapped.

2001
- IRD regroups and introduces new frames made out of Prestige Cr-Mo and Scandium.

2002
- After 2 years of playing with chains, IRD developed a hand-removable connector link for Campy 10-speed chains

 

From the Mountain Bike Hall of Fame

 

This is a letter of nomination into the Mountain Bike Hall of Fame for Rodney David Moses founder of IRD/Interloc Racing
Design in the category of Industry. Because of his product innovation and support of grass roots MTB racers, this would be most appropriate.

In the early days of MTB racing Rod created state of the art bicycle components and was constantly trying to improve the current trend of componentry. Instead of forged parts that required large investment capitol, Rod was innovative in the use of aluminum extrusions and machined parts in many of his designs, just like the two bolt infinitely adjustable seat post
he created for first generation racers who were using small frames to achieve extra stand over height. From 1985 to 1987 these first parts were actually made in his two car garage in Winters California that over looked the Putah Creek Irrigation Lake. As Rod relates, one of Paul Thomasberg‘s favorite things was to wait at his shop looking for the Davis bike club riders to come into view . With his knobby race bike he would hammer down his driveway, fall in behind the pack and drop them on the way back to Davis which was 50 miles away.

With several brake designs, frames, suspension systems, stems, bars, and all sorts of secondary components to his credit, I believe he stands out as a true innovator entrepreneur. His handlebars made of 2024-T3, were the lightest and strongest on the market and was the first to utilize an internally tapered wall.

Other early innovations include a roller cam style brake with huge stopping power, the world renowned two bolt seat post clamp, and the list goes on. Rod was one of the first component designers to use these 2024-T3 high grade aircraft alloys in that era. He had a considerable following and his designs can still be seen today, being exclusively sold by the new Interloc USA company.

Rod was passionate about sponsoring Paul Thomasberg in his early promising racing career and was greatly inspired by Paul‘s expert class win at the historical 1985 NORBA Nationals in San Luis Obispo California. At this race event a good number of racers had bent and drooping handlebars due the roughness of the course and this was inspiration to create the Infinity wall flat bar. Rods father being a USAC midget champion of the 1950‘s was a big influence on his desire to sponsor as many aspiring racers as IRD‘s small resources would allow.

After taking Raymond Baldwin in as a partner and moving to Selma Oregon in 1987 IRD/Interloc Racing Design gave substantial support to the growing single speed movement of the Pacific Northwest in particular the infamous Dave Grey, one of the founding fathers of the modern single speed world. It can be said that Rod is considered one of the first retro grouch enduro persona‘s of the 1990‘s.

Not only was Rod Moses a designer, but an avid cyclist as well. He Attended many off road races and was active in promoting his designs And mountain biking when he wasn‘t out in the boondocks working up a sweat. His designs were race proven, by himself and by sponsored riders, in addition to the normal R & D. He may not have been bankrolled by mega-dollar corporations, but I believe he has had a significant impact on current ATB bicycle design and deserves to be recognized by the MBHOF as one of the pioneers of the mountain bike
industry.

Interloc Racing Design / IRD Between 1983-1999
List of innovative designs


1984
A local amateur mountain bike racer invades Rod‘s machine shop to get a custom seat post made. From that one post, IRD starts getting orders from other racers and IRD is drawn into the design and manufacture of all things OFF-ROAD.

Seat Post (1984)
First extra-long aftermarket seat post Micro Adjustable extra-long rail support. First to use hard anodizing most copied seat post design in recent history.  U.S. patent sold to Kalloy Industries (1995)

Infinity Taper Wall Handle Bars (1984)
The “first MTB taper wall handlebar ever!” This bar was made from .120 wall 2024-T3 and Reamed from both ends. 7/8 diameter with spacer for stem.  At 235 grams the bar lasts forever and bars ends are secure.

Center Pull Rim Brakes (1984)
Center Pull Progressive: first U-brake available. First product based on aluminum shape extrusions Superior to Shimano U-brake as it had more range of pad adjustment, Mechanical advantage and a more user friendly quick release.

Macaroni Stems (1985)
These Stems were one off the first to use petite dual (5mm) binders and with a lightening hole on face, now an industry standard.

1987
Raymond Baldwin becomes 50% of Interloc Racing Design. Rod and family move from Northern California to Selma Oregon. Rod and Ray begin a successful partnership. Ray’s industrial design talent and Tool making ability bring IRD to next phase of exponential growth.

Rotary Rim Crusher: (1988)
Use of a single sided cam to generates a tremendous amount of “modulated precise power”. The chain stay Version had a chain suck feature built into the bridge. Good Mud clearance and tire removal is user friendly. Can stop a bike even in the snow!

Frame miter fixture: (1988)
Rod designs the in-position miter frame fixture. Ray completes fixture and IRD is now able to build frames of unique and innovative geometry in small numbers. Long front centers and ultra short chain stays are the focus of IRD frame design. This unique frame fixture allowed IRD to explore long pedal crank bikes for expedition Mountain Biking. These IRD
frame geometries are now industry standard.

Long Pedal Crank Bikes: (1988-1993)
IRD build and sells Off-road bikes with specific geometry for 190mm (and longer) pedal crank bikes. Extensive work in this long pedal crank area of study is pursued. Rod still feels strongly that entry level ATB and sport bikes should come with 188mm pedal cranks, some even with 195mm, this is an unexplored and underrated segment of the market.

Switchback Cantilever:(1989) This brake made a modest amount of multiplied power with a unique cable routing. Great tire clearance for wheel removal.

Tubular Brake Booster: (1989) Many customers were expressing a need to stiffen up their canti- brake systems and this Tubular booster filled that requirement.

Remote Quick Release: (1989)
This device allowed the rider to release his seat post binder using a with a cable shifter. This design was finished just in time to have the Cross- Country market segment decide they did not need to make seat height changes. The RQR and The Hite Rite become paper weights.

Expedition Fork (non- suspension): (1989)
One of the first ATB forks to be constructed with NO welding. At that time, the Bontrager fork still had welded on brake mounts. The fork crown and blades both flex in unison to make the smoothest ride ever for a non-telescopic modular fork. The clamp on brake mounts allowed the use of U-brakes or cantilevers. This fork is still prized by single speed riders.

Cross Country Expedition Telescopic Fork: (1990)
One of the first ATB shock fork to use a fully sealed bellows system to eliminate the need for high friction wiper seals. One of the first forks to use elastomer springs. Weight is 2.8lbs.with a titanium steer tube. Use of hard anodized surfaces for stanchion to sliders contact was very innovative for that. With the fore and aft flexibility of the IRD Torsion crown and the supple movement of the sliders it is still a great cross country fork by today's standards.

Widget Brake: (1990)
This brake was an invention that came out of the swing arm bike project. There were no production crossover brakes to be had at that time and many full suspension bikes were in development during that era. Kim Sonier won some of her first downhill races with IRD shock forks and rim brakes.
Key Features of Design:
Modulated, tunable, controllable power application.
Threaded crossover rod allowed quick and easy pad clearance adjustment and allows for quick tire removal. Sold 2000 sets to Trek for its landmark 850-swing arm bike

Full Suspension Frameset: (1992)
The first of its kind to use a low forward pivot location that is now a popular variant.  Rod received notice of patent allowance of claims but was late with drawing revisions due to the distraction Ray Baldwin‘s retirement in 1993. Rod did receive a design patent that covers the curved shape. Paul Thomasberg takes 3rd overall in national down standings on this bike.

Current Status:(1993-present)
Raymond Baldwin retires at age 62. Rod sees the consolidation bike industry on the horizon. Company name is sold to new owner. Rod is retained to help with new product line. Seat post design is revised as the Quadzilla seat post still in production today.

Ray is now a highly successful snowbird that divides his time between ocean kayaking and bicycle riding.

Rod has become computer literate and is doing innovative industrial designs for large manufacturing firms and is also involved in dirt track racing in the Pacific Northwest. Rod is still working on some off-road component designs for a few industry clients.
