Every answer, researched and cited.
~30 sources per product, one verdict, with receipts — every claim linked. The gear decisions riders are weighing, the products we’ve taken apart, and the repair jobs done right.
Not a spec sheet on one part — the question behind it. What's changing, what the evidence says, what riders report.
- Crank lengthShould you go shorter?Across cranks from 120 to 220mm, maximum power moves about 4% — the lever was never where the watts were.Read the research →
- Handlebar widthShould you go narrower?Narrow is the new aero — and from 2026 the UCI is drawing a line at 400mm.Read the research →
