Are Suspension Forks Beneficial for Gravel Bikes?

Question

Which advantages do suspension forks bring on gravel bikes?

Answer 1

Suspension forks on gravel bikes provide improved strength to the front wheel helping in cornering, grip and braking. This promotes further trust and control when riding on harsher terrains. Moreover, suspension forks may also decrease hand stress and enhance comfort with tests showing 6 to 11 percent less vibration at the handlebar as compared to non-suspension forks.

The Lauf fork has quite an advantage over a suspension fork; it's half the weight (400g versus 800g), zero maintenance (as opposed to regular maintenance on hydraulics), are MORE aerodynamic than a regular fork (5w apparently) as apposed to a penalty on hydraulic suspension forks, plus it is proghessive damping (due to the spring design) and has zero lag like a hydraulic fork.  Yes, I did my homework, that's why I have one!  Leaf springs are a no brainer on gravel bikes

I almost thought it's an april fools special how much gravel is backtracking to old solutions... Now as i'm half through i'm hoping the next segment will be about how flat bars will improve steering

I would have loved your comments and comparaison about the LAUF fork that is a zero maintenance and very light 30mm suspended fork..

---

It's also worth mentioning the suspension stems. They add comfort, look better than suspension forks and weight less.

You should do a content on the Lauf Fork. Zero maintenance and it improves aerodynamics!

The Lauf fork seems to be well-suited for gravel bikes without the maintenance headaches.

I fitted a cheap suspension fork to my tourer and perceived reduced rolling resistance.  I believe this is due to reduced "unsprung weight" which has to be pushed upwards over every bump.  With suspension, only the fork and wheel is pushed up, not the whole frame and rider -> less resistance.  Therefore, the rougher the road, the more benefit from suspension.  Downsides were extra weight, a Kg or so, and limitations on front panniers for touring.  Fat tyres may be an easier way to go.   And cheaper.  I can't see a sprung, gearbox gravel bike costing anything affordable for most non-professionals.

The "more capable" gravel bikes mostly seem to be bought with the same logic as people buy pickup trucks. "What if I want to bikepack up a mountain one day", meanwhile they are used for 80 km rides with an extended cafe stop on mostly roads.
I completely understand drop bar bikes with some extra tire clearance, makes sense for the average rider who doesn't really care about getting the last bit of speed on the road to go for a bit more comfort and ability to use some gravel roads. But by the point you add suspension and those massively wide flared bars, you've probably arrived at owning a worse mountainbike.

My Gravelbike is a full-sus XC bike (Specialized Epic Evo) with 700x47 Gravel tires (Specialized Pathfinder Pro).  Very fast on pavement and gravel while still being capable on easy to intermediate singletrack.   In my opinion, better than a Gravelbike.   Dylan Johnson, the Pro Gravel Racer, uses a hardtail XC bike in Gravel races and finishes in the top 20.

Love your content! Tempted to put a Thunder Burt Super Ground 29x2.1 on my Checkpoint SL.

However once I put on road wheels, I dont want a wannabe mountain bike. Suspension fork really doesn't fit that use case imo

you have mentioned gravel bike getting suspension. Cannondale has introduced the slate with mtb gears and lefty suspension 8 years ago... The topstone even introduced a back sus.

The future of gravel is more like fully suspended e-gravel bikes.

Ho no, we have the Cannondale Neo Topstone, a fully suspended e-gravel bikes that is a couple of years old.

A detailed review would be great because you excel at that.
