Press Release: Kurvyflats

Love them, hate them…. mudguards have been used on bicycles for many decades. Before 2012, they come as a permanently preformed fender, long and always following the shape of its tire arc… after all, you are trying to shield a tire. The majority of mountain bikers today would not want to use these said preformed mudguards because they simply don’t match the handsome stance of a modern mountain bike. Effective but an eye sore to look when installed. It’s like a side window deflector on a Ferrari.

A good number of ardent mountain bikers would ride on wet days without mudguards and are very much aware they’ll be sullied, which they would rather have than using one of these preformed bike fenders that most of us learn to hate for aesthetic reasons. One would rather choose to be dirty than look funny. Then in 2012, the attitude of a lot of mountain bikers changed when the market introduced a simple pre-cut, flexible and flat plastic sheet type of guard. They sure do give a nice and simplistic appearance and lots of riders started using them, including myself. It is now so ubiquitous, that it is not uncommon to see up to half of riders you’ll encounter on the trails having this mudguard.

The mountain biking world sort of embraced this product mainly for its minimalist and aesthetically pleasing looks. But does its non-intrusive looks really doing a good of a job it was meant for? I hate to be negative especially on a great product design, plus I was generally happy with the one I got. In an open and unbiased assessment, it is only able to shield your stanchion, fork seal, maybe headset and probably nothing more. As for one’s face protection from mud.... individual mileage may vary but chances are, you’ll still regularly get them. The inherent attributes of flat sheet class of mudguard, is that they are short. The first bend during installation that creates the half-pipe shape will always gonna end up with a straight fender. Stretching it longer will just hit the down tube and is not nearly close enough to match a good fraction of the effective shielding of a conventional preformed Mudguard.

Living and riding in the lower mainland (Greater Vancouver Canada) since the early 90’s, surely did include countless rides on muddy days. Often will finish a soggy ride with mud starting from significant few dots on my face and gets really worse quick as you go down towards the foot. And this unfortunately persisted even after I had the cool looking flat sheet mudguard. It was one of the truly awful soggy night riding, back in the Fall of 2014 that for some reason, I had my attention on my mudguard longer than usual and began to ponder…. sort of tripping without the high. If it is made longer to be more effective, it must bend a 2nd time but how? That must have planted the seed subconsciously to find ways, which did finally come over 3 years later!

The idea is a simple pair of slits and some shape adjustments plus an extra inexpensive 4” zap strap and voila, you got yourself a curved flat sheet mudguard that can be made significantly longer, hence more effective.
The would-be Patented Idea

After a patchy wet ride at Whistler bike park
After a patchy wet ride at whistler bike park
On a wet trail with little drizzle or no rain and a few patchy 1 to 2-foot wide paddles, you will find your upper half jacket, up to your face be mud free. Even on a heavier rainy rides with trails having longer stretches of thinly water layered earth, it will be very rare to have mud on your face. If you got a few on your face, it’s probably from the rider in front of you.

Kurvyflats Mudguard:
• 1.3 mm thick engineered plastic balancing weight, flexibility & strength
• They are stiffened to resist flapping on drops and very rough trails
• Each side mounting arm has 2 pairs of strapping holes, that offer 3 angle positions for more leverage in adjusting fender tip proximity to tire
• A tiny pair of holes are added to aid in folding and relieving stress
• 6 colors available – red, white, blue, green, orange & gray
• MSRP: CDN$ 30, includes six 8” & two 4” zip ties
• Canadian Shipping cost the same for qty 1 to 8; USA Shipping cost same for qty 1 to 5
• Contact: http://www.kurvyflats.ca

This is the new revolutionary mudguard known as kurvyflats. Simple, brilliant, works! Inspired by riding in the trails of North Shore, Delta Water Shed and a little bit of SFU. All happened in Vancouver! So, Keep Riding... Feel the air not the mud!

 @shoreboy1866: great feedback shoreboy. kurvyflats are made in canada and should be able to cut cost down eventually in time. target is to sell them in local bike stores. online is full of $7 flat mudguard and not a good place to sell these. northshore bikeshop at lonsdale ave north Vancouver & rocky cycle in king george hwy in surrey will be carrying them.

 mud hugger is a great product & i am not sure which shields better, but will say this though, i tried testing kurvyflats installed like a mud hugger (tip proximity almost touching tire) and find mud shielding is noticeably less than when it is up by 5 to 6 cm. mud hugger may have longer length to compensate but not totally sure. i never tested mud hugger to compare.

  • 1 1
 @Fulgacian: tried numerous thickness plastic sheet & we found 1.3 mm to be the optimum for the length of the mudguard overhang loads. Flat mudguard looks simple & easy to just cut any sheet but maybe on traditional short flat fender and NOT on kurvyflats. Even a small deviation on plastic formula will cause whitening on high stress(heavy folded area) & not to mention the resistance needed when further folding the entire mudguard to mimic an accidental crash.

 @jackdbiker: Yeah - that's a rookie error not using them! I use a 2-3mm drill piece then a V sharp box cutter to remove a sliver of plastic.

 @jackdbiker seems to me that in being so defensive (replying personally to all the negative feedback on here) of this product you probably know, deep down inside, that this product sucks and is going to bomb. Maybe you’re in denial? Or just have such bad taste that you can’t see that very few people will want to make their expensive mtb look ugly by strapping this piece of garbage to it for such marginal gains..especially when there are better products ie the mudhugger already on the market (better because they look miles better while having a performance that anyone with any common sense will assume to be similar just from looking at them) I would say cut your losses and try to sell what stock you have (good luck), but don’t waste any time or money on any marketing or producing any more...Seriously, not trolling, they really do suck..if basically everyone on pinkbike says so that’s pretty much your target market right there

Perfect timing for the coming winter riding!

 Not a chance! There is no front mudguard that reduces this at all, the water that fires onto your shoes is from the very bottom of the tyre whee it contacts the ground, unless you have a mudguard that practically scrapes the floor you cannot stop it spraying your foot.
  • 1 0
 @brooms: you are right here and don't disagree with you. i had observed (and video it as well) the water/mud pattern spray coming off the front wheel. When just riding a straight line, a good portion of them are shooting straight up. when this happens, a longer mudguard will catch most of the mud & drops them down. If your mudguard is short, obviously these high percentage of mud will spray onto your down tube and distributes them to your legs and also down your shoes. However, there are also a significant portion of mud will spray at lower angle & definitely hit your shoes that no front mudguard can stop which i think is what you are saying.

 So how long is it? Mudhugger front race is 450mm and looks a lot less janky than this.
  • 1 1
 kurvyflats has 354 mm overall length as measured flat. a better comparison maybe is the length from the middle of arch holes to back tip which is 297 mm. mudhugger has much longer front portion and probably better for minimizing forward or front trajectory mud spraying that naturally comes off. These tend to "spray back" on rider as he/she moves forward but does not normally goes higher than handle bars. Other flat mudguards has an additional front piece with a front fold that has to be installed on top of the main mudguard. that i thought was more janky feature & i did not bother with it.

 A downtube mudguard works wonder (gut fender for instance, light and not really big). In fact it's more usefull than a marshguard. But both together are even better. The marshguard blocks the mud you'd throw up & forward and roll into, the down tube fender blocks a lot of what the wheel throws backward. For the front wheel a mudhugger or zefal's equivalent are great, gut fender for the downtube. My ridding buddies were joking once that I was not riding on the same trail as them, as I was not splatered with mud contrary to them.
  • 1 0
 i had bought a down tube guard too after finding the limits of the original flat mudguard. The rubber straps broke early though & gave up. Yah down tube guard helps but if you count all the money you'll be spending, why not just buy a mudguard that will shield most mud coming towards your face & upper body. bike will always going to get mud no matter what, plus down tube guard doesn't look nice.

 I try to not ride if it is really coming down as trail is so soft & get really destroyed.
