14 reasons to buy

  • Experts admired the geometry on the overdrive: with a short rear-triangle on the XC (for clearing obstacles) and slack angles on other models.
  • The adjustability of the fork impressed, on all models, with a bar-mounted 3-position lockout on the Carbon Pro 29.
  • The paint job on lower-end models made the bike look more expensive than it was, while the minimalist black-on-black graphics of Carbon models was seen as classy.
  • The Carbon Pro 29 was used as a ‘world champ level race bike’ by professionals, while the Overdrive 1 was capable of tackling intermediate trails.
  • The Overdrive 1 is a budget bike with quality componentry, including an Acera rear derailleur with hanger, quick-release levers, a modular chainring and disc brakes.
  • 27.5” and 29” wheels both roll over obstacles and accelerate well. The high bottom bracket on 29” models allowed for great clearance over obstacles.
  • Experts dubbed the Overdrive 1 ‘a bargain’. Owners said it was good value and affordable.
  • On basic offroad surfaces, the Overdrive struck riders as a solid and comfortable ride.
  • Although not a lightweight, the Overdrive 1 was generally considered to be a good weight for the price.
  • Assembly was simple for many owners.
  • The SRAM drivetrain on the Overdrive 2 / 29, was an unexpected addition in this price-range.
  • The quality of the WTB ‘Nine Line’ tires on the 2 / 29, was remarked upon.
  • Users and experts said the Overdrive both climbs and descends well.
  • The Tektro mechanical disc brakes on lower-end models were described as decent, while the hydraulic Shimano discs on the Carbon 29er, were considered superb.

5 reasons not to buy

  • The compromise of durable, yet low-cost parts, resulted in a ride that was heavy for some users.
  • Chainslap wasn’t uncommon on lower–end models, with one expert recommending the addition of an aftermarket chainguide.
  • The provided tires on the Overdrive 1 were described as more suited to cross-country than aggressive trails.
  • At 740mm, the handlebars were too narrow for some riders.
  • The Overdrive 1 was sometimes criticized for having cheap pedals and uncomfortable grips.

Bottom line

The Diamondback Overdrive 1 is recommended by experts as a great low-cost entry-level mountain bike. It is renowned for being one of the best bikes in its price range, in terms of componentry and build. It’s important to note that it isn’t built for hardcore trail-riding but is definitely suited to general offroad and cross-country use. Other models are available, all the way up to the level of the ‘Carbon Pro 29’, which is a professional race bike.

Final Review: Diamondback Carbon Overdrive Pro 29er

It’s stiff enough to transmit even my weak pedaling ability into forward motion, without being so stiff that it results in fatigue by juddering over every bump.
