Interloc Racing Design (IRD) is a bicycle parts maker. Whatever strikes us as being a true need of the cyclist, you can count on us to look into it.

Currently we see ourselves creating high quality components for serious riders, especially hard to find parts that the larger manufacturers have forgot about.

“I gots to have more drillium”
Repost from Bike Breath

The Soma Pescadero Glamour Shots, 17 slides worth. Have a sniff! It’s been a very long time since I’ve had a road bike in my life. I’ve learned a lot about what I like in bikes during my time away from them and this time around I aimed to curate the comfiest road bike build that’s still meant to cover a lot of ground quick. I chose this frame over something with a carbon fork with that in mind, I wanted rim brakes for the more compliant fork (and other reasons), and 700x38 tires were what I had in mind to eat up our not so great roads while keeping me stabilized and speedy. I got the IRD brake levers because I’m picky bout hood shapes and these ones looked like the shape I prefer. As soon as I saw them I wanted to get more drillium. I had drillium dreams and I got lucky over the winter and found the Velo Orange crankset on a clearance sale. I will go more in depth on all of the components in a first impressions ride YouTube video soon, but if you have any questions drop them below! Summer on 😎

Big climbs. Bigger range. No compromises.

The IRD Rock Jock Asymmetric Jockey Wheel Set rethinks what’s possible from a derailleur pulley. Its smart, eccentric design increases derailleur capacity, helps eliminate chain slack when using wide range cassettes, and maintains the precise shifting performance riders expect from Shimano 11sp and lower drivetrains.
Upgrade your range without replacing your derailleur.

👍👍

Hannah leads the city of Raleigh’s micromobility program - so you know she’s gotta have a fire commuter.

She says “when I moved to Raleigh, I transformed my only bike into my “car” - which meant adding racks + a basket + other features to make riding loaded feel more comfortable. Several thousand miles later, I learned a lot about what I liked about that setup (and what I didn’t!) to build this bike. The biggest change being going from a aluminum + carbon fork frame to a fully steel frame. And custom wheels perfect for supporting heavy groceries. I can go fast (if I must!), but speed wasn’t the primary goal of this build. It was utility, fun, and comfort.”

She definitely made a great choice using an Space Horse for her new car.

The components she landed on balance performance and longevity well. Plus there’s touches of steez from with a beautiful stem cap and who added a few extra braze-ons and a color shifting harlequin paint job.

For those of you looking for a bike painted by you’ll have to get a brand new custom one! He’s not taking any refinish work for the foreseeable future.

Thanks for trusting us to build up a practical and pretty bike Hannah!
