We tested the new YT Industries SZEPTER CORE 4 2023. What’s the gravel gravity bike of the German direct sales brand capable of?

  1. excellent downhill performance, extremely fun to ride and confidence inspiring
  2. “braaap“ has just made it into the gravel slang
  3. consistent spec, attractive price
  4. good off-road climbing performance despite the weight
  1. too many design elements
  2. could do with more mounting points for bags and bottle cages

Cycling News

Tom Wieckowski

The YT Szepter rode very well across a range of terrain. If you want one bike to link gravel, tarmac and mtb trails and have a blast whilst you do it, this could be a great option

  1. +Very capable across a range of terrain
  2. +Comfortable riding position
  3. +The inclusion of fork and dropper post inspire confidence
  1. -Suspension fork and dropper post add additional servicing costs
  2. -Some riders may want larger tyre clearances


Will Strickson

VERDICT: YT’s first gravel bike is comfortable and capable, and should appeal to both roadies and MTB riders in different ways


Ben Delaney

An upright bike that early indications show is surprisingly comfortable and fun to ride… at a good price

  1. Clear sense of purpose (it’s a fun bike, not a race bike); good value; confident handling
  1. Heavy; pigeonholed outside race and bikepacking gravel spheres


Tyler Benedict

When a press email for a new gravel bike starts with “As you know, YT Industries has always been a gravity orientated mountain bike brand…” and both trim levels come with a Rockshox Rudy fork, it hints at what’s to come.
