16 reasons to buy
- Unsurprisingly, the Carbon Sync’R was appreciably lightweight. The 3.0’s stiff frame aided acceleration and liveliness.
- The SRAM GX Eagle 1x11 drivetrain on the Carbon performed superbly for experts who said no upgrade was needed. Even the 24” kids’ model featured an NX 1x11. The 4.0 sported an outstanding Deore Rear Mech that presented great value to buyers.
- Also requiring no upgrade, was the Fox 34 Fork on the Carbon, which featured ample travel for reviewers. On aluminum models, the Rock Shox fork presented good value, featuring a lockout for street riding.
- Carbon Sync’Rs sport 32mm rims for strength and fat tires. The budget 3.0’s 36-spoke wheels accept abuse.
- The Carbon Sync’R easily tackled trails usually reserved for full suspension rigs - and for some experts, presented a more enjoyable ride.
- This bike received plaudits as to its responsiveness and playful qualities.
- The Carbon Sync’R was dubbed ‘bulletproof’, for its durability.
- The Carbon Sync’R easily tackled trails usually reserved for full suspension rigs - and for some experts, presented a more enjoyable ride.
- Carbon Sync’Rs sport 32mm rims for strength and fat tires. The budget 3.0’s 36-spoke wheels accept abuse.
- On the Carbon, Maxxis Minion tires craved aggressive conditions, while on the 4.0, Rapid Rob tires were fast.

- Carbon Sync’Rs received plaudits as the bike's responsiveness and playful qualities.
- The 3.0 comes equipped with rack and mudguard eyelets for everyday use.
- At the low price-points of the 3.0 and 24 inch models, it impressed owners to see hydraulic brakes.
- Buyers of all models said they were easy to assemble, with the 24” sometimes needing no rear derailleur or brake adjustment.
- All models presented great value, to owners and experts alike.
10 reasons not to buy
- The fork on the 24” was a bit heavy for some lighter kids to compress.
- Both 24” and aluminum models presented a number of minor assembly issues for some buyers, including missing bolts and small damage. The 24” was occasionally troubled by incorrect cable lengths, greaselessness and undertightened brakes. Aluminum models faired worse, having arrived with bent hangers and wheels out of true.
- Carbon Sync’Rs don’t have enough clearance for real plus-tires, only allowing 27.5×2.8” or 29×2.3”. Sync 3.0 and 4.0 models were criticized for featuring narrow tires, at 2.1”and 2.25”, respectively.
- The lack of a boost front hub limits upgrade options for the Carbon model.
- The Truvativ Powerspline bottom-bracket on Carbon models struck experts as redundant.
- Experts agreed that Sync 4.0 models were heavy.
- 3.0 models featured short reach combined with a long stem, which reduced handling ability on rough terrain.
- The 3.0’s fork is coil-only without rebound adjustment. Disc rotor size is limited to 160mm. It was found to lock-out on uneven terrain.
- Frames felt uncomfortably firm on the 3.0.
- The 3.0’s 8-speed transmission and Tourney-only crankset were considered outdated.
Bottom line
Really, when you look at the different Sync’R models, you’re seeing a few horses of significantly different colors. The 3.0 and 4.0 are budget models that both feature compromises on performance and componentry in order to maintain affordability. The 24” is usually received as a kids’ bike with high-quality adult componentry. Aluminum Sync’Rs impressed most owners with reliable mid-range parts and spec. But at the top of the heap – you have the 2019 Carbon Sync’R that can tackle intense trails without hesitation. This bike features componentry that, in most regards, begs no upgrades and almost always impressed.Where to buy
