Why The Syndyt SYB Frame Matters
If you chase podiums, you need every edge.
And the SYB frame is built to give you that edge.
Here’s what makes SYB tick:
- Material: 6061-T6 custom-handcrafted alloy.
- Tubes: Hydroformed, triple-butted to cut weight and boost strength.
- Oversize tech: Stiff tube junctions for max power transfer.
- Chain tensioners: Integrated for fast, precise setup.
- Multi-axle: Works with 10 mm bolt-on, 15 mm or 20 mm thru-axles.
Remember, this isn’t a one-size-fits-all.
Syndyt built two lines:
- Pro (top-level) sizes, for riders 5’8” and up.
- Mini/Junior/Expert sizes, for younger racers and smaller builds.
Every tube meets Syndyt’s strict quality checks.
Every weld is smooth.
Every frame ships with droptouts, axle hardware, and headset bearings.

GET YOUR SYNDYT SYB FRAME NOWReal Rider Feedback
- Alex M.: “On the Pro XL, I shaved .2 seconds off my lap times thanks to the extra stiffness. The frame tracks straight out of the gate and holds firm through rhythm sections, so I could focus on acceleration, not corrections.”
- Jamie R.: “After swapping to the 20 mm axle, wheel alignment stayed perfect even under brutal berm loads. The built-in chain tensioners made mid-race adjustments a breeze – no more loose slack on high-speed straights.”
- Taylor T.: “I push hard in sprints and felt zero flex around the BB shell. Every pedal stroke translated directly into forward momentum, giving me an edge on the final straight when every watt counts.”
- Casey C.: “Riding the Mini XL, I noticed how responsive the front end feels in tight corners. The Hydroformed top tube and triple-butted downtube resist twisting, so I could lean in deeper without losing grip.”
- Jordan B.: “On rough, bumpy sections I ran 15 mm for a bit more play – but switching back to 20 mm gave me the stiffness I needed to stay stable. The oversize tech at the tube junctions is no joke; it locked up my setup exactly where I wanted it.”
- Riley F.: “The grey finish has held up through dozens of slides without chipping. Beyond looks, the consistent weld thickness means no hotspots or weak points, so I’ve been ripping rails and drops with full confidence.”
