Description

The Stay Strong V5.1 BMX Race Frame represents the evolution of Stay Strong’s most successful race platform, refined, re-engineered, and pushed further than ever before. Building on the stiffness, proven race geometry, and unmistakable Stay Strong look of the previous generation, the V5.1 delivers even greater performance, strength, and usability. 

At the core of the frame is the BB86 TTL (To The Line) bottom bracket, combined with an oversized seat tube, down tube, and bottom bracket junction to maximize stiffness and power transfer. The winning race geometry remains unchanged ensuring explosive starts, predictable handling, and high-speed stability.

The biggest upgrade comes in the form of the bespoke Race DVSN dropout and 5-point dropout system. This innovative design permanently fixes the inserts and disc hanger to the frame, improving stiffness while making wheel and brake adjustments faster and easier. The custom dropout also allows for a taller seat stay, resulting in a stiffer and wider rear end, while rear-access chain tensioners make wheel alignment quick and hassle-free.

Stay Strong dropouts are supplied with 10mm inserts as standard, with an optional 15mm thru-axle kit available for riders running a 15mm rear hub. The V5.1 is the most technically advanced and extensively tested race frame Stay Strong has ever produced, featuring triple and double butted tubing, a tapered head tube, smooth welds, and race-proven construction throughout.

Visually, the V5.1 stands out with exclusive dual-color schemes, upgraded water decals, and hidden details from the “STY STRG CODE” with every frame featuring a clean and fresh look, race-ready finish.

Note: Frames are supplied with a disc hanger suitable for 140mm disc rotors.

Features
  • Proven race geometry, unchanged. Explosive starts, predictable handling and high speed stability carried straight over from the previous generation, here in the Expert size.
  • BB86 TTL bottom bracket. An oversized seat tube, down tube and bottom bracket junction back it up, so your effort out of the gate goes into power transfer, not flex.
  • Race DVSN 5-point dropout system. Inserts and the disc hanger are fixed permanently to the frame for a stiffer, wider rear end, with rear-access chain tensioners for quick wheel alignment.
  • Triple and double butted tubing. A tapered head tube and smooth welds finish the most extensively tested race frame Stay Strong has produced.
  • Disc ready out of the box. Supplied with a disc hanger suitable for 140mm rotors, plus 10mm dropout inserts as standard and an optional 15mm thru-axle kit.

BMX race bike sizing

Race frames are sized by class, and the class you ride is set by rider height rather than age.

SizeRider heightTop tube
Micro (18" wheels)Under 120cm16.25"
Mini (20" wheels)110 to 140cm17 to 18"
Junior120 to 150cm18.25 to 18.75"
Expert130 to 170cm19.5 to 19.75"
Expert XL145 to 170cm20 to 20.75"
Pro150 to 175cm20.25 to 20.75"
Pro XL165 to 180cm21 to 21.25"
Pro XXL170 to 185cm and up21.5 to 21.85"
Pro XXXL175cm and up22"
Pro XXXXL180cm and up22.5"
Cruiser (24" wheels)175cm and up21.5" and up

Heights overlap between classes on purpose. Where you land in two, a growing rider is usually better on the larger, and a rider who wants the bike to turn faster on the smaller. Some brands label the Pro size Pro L, with the same fit.

How to measure

Stand your rider against a wall in the shoes they ride in, heels flat, and mark the top of their head. Measure from the floor to the mark.

  • Between two sizes and still growing? Take the larger size.
  • Racing gates and wanting the bike to turn faster? Take the smaller size.
  • Top tube is the number that actually changes the fit, so compare it against the bike they ride now.

Not sure? Send us their height and we will tell you what we would put them on.
