De-Fender update (this is not it)

Gerard Vroomen - 15-Jan-2020
It's 2020 and of course we had hoped to start shipping our De-fender system by now. And to state the obvious: We're not.

It's been a lot harder to get the last details ironed out, but as of yesterday we have. So now we will update the final drawing, get the final prototypes and then immediately go into production. I don't know yet what exact timeline this will take, as soon as I do I will update you here.

In the meantime, those who want to have a fender - any fender - on their WI.DE. and cannot wait for the De-fender, or for those who own and U.P./U.P.P.E.R. , there are of course clip-on options. Here is Andy's personal bike with his favorite fender, the SKS Speedrockers.

Of course like any fender, these do limit you in tire size somewhat. It will still fit these 700x42c tires comfortably, but as always, it does depend on the exact tire and the rim it is mounted on.







For 650b tires, the clearance is generally better than for 700c tires. This effect is limited on the Speedrockers as the way the blade is attached runs too close to the tire, but even there a lot of 2.25" tires will fit. To show you the extreme situation, here are some photos of the Speedrocker with the G-One Speed 27.5 x 2.35" tire. It has 3mm of clearance on the sides (much more in the center) so I don't recommend you ride it like that, but it visualizes the clearance very well. 

These photos are meant as a service to you, so please no comments on Andy not cleaning the bike or the office first!

Can you give us a hint as to the size tires the WI.DE will be able to run with the DE.Fenders on?

Absolutely! 650b 47mm is completely my favorite size

Well, that tire on the WIDE with a fender won't be any problem at all.

Yes, you should have 5-10mm more clearance than that G-One Speed shows depending on where you measure, so more than enough.

That's great news! I appreciate your response. I'll have to include pictures once installed!

For 700c, the clearance will always limit options a little bit, but the goal is at least 700x42c. For 650b, things are easier, and the goal is that the fender won't affect tire options at all. We're almost at that point, but not quite yet as we have to get the curvature exactly right for that to work.

How spooky, I just took delivery of SKS Speedrockers to put on my OPEN U.P. - was juts scratching my head about how to fit them, then this email comes in. Thank you for being a mind-reader.

It may be a stupid question but I thought that the de-fender solution only applies to wi.de, and not to the up/up-per. Am I correct?

Hi Stephane, that is correct, the De-fender is only for the WIDE, but the SKS Speedrockers you could mount on any model.

Hi Gerard. Am I correct in saying the up/upper use the same fork as the wide, and you will therefore be able to use the front fender? If so, will you make it available separately?

Thanks

Yes it's the same fork. Not 100% sure yet on the packaging.

Are there any pictures of your current prototype how it's going to look like and how you are going to mount those? I assume I just didn't find the link. People want to know if they should wait or go for SKS. By the way, is SKS working with you on that project?

No pictures ready to share yet as we are still filing something, but yes, we are working with SKS on that (but it's nothing like the Speedrockers and Andy's recommendation also has nothing to do with the De-fender).

Drop the "custom" path and simply put certs on your bikes so users can choose to mount what they want. Forget those who wine about them taking away from the appearance. Form over function is never a good option.

We would never put form over function, I don't think you see that anywhere on our bikes. And the De-fender will be no different, great function (better tire clearance within our frame than any stock fender) and as a by-product great form.

I would argue that having to remove your BB to change a derailer cable is putting form over function : )

I discovered that the Speedrockers will work very well on my Upper with 650b wheels and 2.1" MTB tires.

Basically the main thing putting me off from buying an UP is the lack of a (proper, non-click-on) fender option. So, when checking this post I got very excited first, then slightly disappointed when understanding it's gonna be for the WIDE only. But then I got a little excited again when reading the comments saying that the front de-fender might fit on the UP as well (because of identical fork). I would love for you to announce a rear de-defender for the UP as well. It might tick my purchase decision towards the UP. It would seem not to be that much a difference in design, or is it?

Hi Sebastian, indeed the De-fender front fender will work on the UP as the U-Turn fork is the same for UP and WIDE. The rear fender won't work and there is no easy way to make it work, otherwise we would have. So the best option for the UP would be a clip on or saddle fender on the rear and the De-fender on the front.

A bit off brand here but any chance the De-fender front fender could work on the Exploro flat mount Fango fork? Fork has a hole underneath it I think...

Bought a set of these Speed Rockers on your recommendation a few months ago, and they have been a life saver in the dreadful wet winter we are having in the UK! Thanks for the steer.
