D-Dubs Works

An independent maker of free bike-building tools. No manufacturer pays us for placement, ordering, or verdicts — the tools exist so a rider can know, before spending a dollar, whether the parts they want actually fit together.

What we build

🚵 BuildMyMTB

The flagship. Mountain bikes — XC to DH, hardtail to mullet. 26 build slots, 20 live compatibility rule areas.

“BuildMyMTB is a free, unbiased bike-building tool with accurate data: it tells you whether parts fit together, what they cost, and what they weigh — verified against the people who make them, favoring no manufacturer, and honest about what it doesn't yet know.”

How we work

Unbiased, structurally

No brand pays for placement, sort order, or a favorable verdict. Affiliate links may fund the tools — they never bias them, and every one is labeled.

Straight to the data

Every builder loads directly to the parts. No pop-ups, no newsletter walls, no cookie interstitials — a rule, not a preference. This page is the one “brochure” we allow ourselves, and it lives where no tool is.

Honest about sources

✓ Verified means checked against the manufacturer's own published spec, source linked on the part card. Everything else is labeled sample data until it earns the check.

Free to use

Every builder is free. No account is required to build, check fit, or share a build link.
