Single Side Bike Fork

The Single Side Bike Fork should stand up to heavier bending forces than typical forks, merely because of physics and asymmetric. However, because of its completely different construction, the fork is stiffer than most 2-legged.

One facet is the spring (air or metal spring) and also the different side is the damper. This implies the edges are always operating against each other. The fork is torn on its sides and it doesn’t behave the same whether or not you turn left or right.

What Is Single Side Bike Fork

Advantages Of Single Sided Bike Fork

  • The top is attached sort of a twin crown downhill fork, that is way stiffer than a single-crown.
  • The wheel axle is one-piece with the bottom half, which is stiffer than a quick-release shaft (which isn’t solid at all) and on the same level as a fifteen-thru-axle or twenty thru-axle. This style is employed conjointly on cars wherever the wheel does not have support from the opposite facet.
  • The biggest difference is within. Whereas normal forks have round tubes that slide on the oil film, the Lefty uses needle bearings on an sq. profile (same as the front leg of Boeing airliners.)
  • Such resolution works with nearly the same friction beneath significant side-loads, whereas sliding tubes, once side-loaded (uneven compression of legs), do get friction losses (rolling resistance wins).
  • Having a typical fork with one leg would not work; such a fork would bog down. Having a bearing-fitted 2-legged fork is overkill and extra weight.
  • The heaviest Lefty is still lighter than n lightest carbon 2-legged.
  • You can replace the tire without removing the wheel.

Disadvantages Of Single Sided Bike Fork

  • If you like to get rid of the front wheel, you would like to get rid of the brake caliper also.
  • The axle works solely with Cannondale hubs.
  • The front of the bike can look unbalanced till you get used to it.
  • Pre-2013 models of Lefty aren’t sealed, having the bearings track just under a rubber sleeve. This needed nearly constant maintenance. Post-2013 models have a rubber-sealed leg with bearings further within and with one plain bearing at an all-time low that permits for service intervals as normal forks:
  • Previous models, as some bikers on forums complained, had a lot of linear action: they were easier to bottom than traditional forks. therefore, currently, the newer ones should have a lot of progressive compressions. (This is opinion-based mostly, however, quite a lot of it is online, and there are not any measurements.)
  • A Lefty is far more durable to service than a standard fork. you wish for a few special tools, and also the assembly is complicated.


As we see Single Side Bike Fork has many advantages but every coin has two sides. So, it has disadvantages also. Just we have to know how to use it wisely. Single side bike fork is a useful element until you use it correctly.

Frequently Asked Questions

What is the advantage of Lefty fork?

Compared to a standard fork of the same travel, the stiffer Lefty ought to offer additional exactitude, control, and active suppleness in the rough track, or underneath hard braking and cornering.

Can you place a Lefty fork on any bike?

Until now, unless you a) own a Cannondale or b) had a frame custom created to suit their standard, you could not run a Lefty suspension fork on your bike. Assuming you are not suspended by the look of it, there are a few reasons you’ll wish to.

Which is a healthier suspension fork or a rigid fork?

A suspension fork provides a more comfortable ride on rough roads like off-road or bad-quality urban or city roads. If your ride is generally on good-quality paved roads, a rigid fork is additional sensible.

How does one take away a Cannondale Lefty fork?

The extraction bolt is found on the facet of the wheel opposite the Lefty. Pull the front wheel far from the Cannondale Lefty, and slide it off the shaft. If the wheel cannot be removed with relative ease, loosen the hub extraction bolt. Use a four mm hex wrench to loosen the 2 Cannondale Lefty clamp bolts.
