Merida Silex 700 gravel bike review

Jul 2024

This Merida Silex 700 may be lower down the brand's gravel range of bikes but, with a mixture of some major tweaks to the geometry and overall design for 2024, plus a great selection of kit it is an affordable gravel machine which is capable of taking on more technical terrain than most. With some rather classy paint jobs the whole range looks great, too. Five things that weren't cool - until gravel happened Scott Addict Gravel 10 gravel bike review Gravel bike suspension and dropper posts - do you need them?

The MERIDA catalogue says it’s an all-rounder, but covering everything from gravel racing to bikepacking sounds like quite a stretch. We put the new SILEX to the test.

Highs
  • Hard to beat in terms of fun

  • Sleek look

  • Enough mounting points for all eventualities

  • Top of the line components

Merida Silex 700 review: A budget alloy gravel bike that punches above its weight

Jan 2022 · Josh Croxton

A budget friendly gravel bike that swaps speed and efficiency for comfort and capability

Highs
  • Shimano GRX is flawless

  • Mounts for bags, mudguards and more

  • Full-carbon fork

  • Carbon-fibre seatpost

  • Hose-breakers and cable adjusters at cockpit for easy servicing

  • Removable hex-key quick release for bolt through axles

Lows
  • No top tube mounts for extra bikepacking bag

  • Internal routing stops at the bottom bracket

  • Doesn't come set up tubeless, and you need to supply your own valves

  • Heavy aluminium wheels

  • Tubeless setup of wheels was laboursome and leaky

  • Pressfit bottom bracket gained a creak after before 1000km
