I do have both tyres here and compared them…honestly, I can’t find that much difference, the rubber mixture might be variable and the profile is at the first look completely equal…there must be a pic somewhere in the forum, but I couldn’t find it quick…
Kojak’s are everywhere relatively expensive…(I believe…)
Edit: Out of curiosity, I took a look on the Austrian post calculator, Marathon’s and a scale…
Should be ~ 82 US$ shipped, incl. PP fee, for a pair (the long way - 10-15 days, no tracking).
I am going to try and patch for now, my internet searches on the Kojaks are slim to nothing in the US, or 52.00/ea on the Schwalbe NA site. There was a pair on ebay, but long gone.
I used to have a pair of Kojaks but sold it because with the type of roads here in the Philippines it will be ripped to shreds.
A friend of mine rode 200kms with him on Kojaks and me on Innovas. His was punctured by a little glass shard smaller that a grain of rice.
So I sold mine from an extra wheel set. The Innovas are pretty reliable but I noticed that one tire has somewhat thin sidewalls from the other judging from pinching the tire. I would want to switch to Schwalbe. I’m just waiting for the tires to wear out.
JFYI, I have recently tried IRC tire for BD-1 (which is not roadlite, this tire does not have specific name). 18 x 1.5, heavier than kojak, but very nice tire.
Hi, I am new to this site so excuse me if I am not making a proper use of the forum.
I have a question, I have just bought online a set of tyres (Schwalbe Black Jack 18x1.9) to give my Kojak a break as I am now using my Strida on rough terrains.
Is this option viable?
Please I need your help.
I just changed tire from Innova to Schwalbe 18’x1.5 .(without fender)
As the gap between the tire and the frames are only about 3-4mm for both front and rear, I’m a bit worried that the said tire may rub on the frames.
After riding for about 50 kilometers last Sunday, I checked the condition of the frames for any signs of rubbing from the tire. The front frame didn’t show any rubbing at all ,but the rear frame got a rubbing marks at the frame (exposing the bare aluminium frame)
My question is , Is it still safe to use the said tire knowing the there is a slight rubbing of the tire to the frame? Will it affect the frame thickness? What is the best option to prevent this rubbing of tire?
Is it due to weight issue(being the rear tire)? Or does it to do with tire pressure?
Please note that when I was using Innova tire (which is 18"x1.35) I had similar issues of rubbing to the fender screws, the reason why I removed the fenders for both front and rear.
Is it due to flexing of the aluminium frame when riding? My weight is only 75kgs. and it is below the maximum permissible weight capacity of Strida which is 100kgs.
I would like to hear your advise or comments.Thank you
I’d say the main issue is that the Strida was initially developed and manufactured for 16" wheels.
Just somebody noticed later that it is possible to use 18 rims with certain, relatively narrow tires…and that’s it.
As long as the the marks are minimal there will be no safety issue, I think.
But of course you’re wasting your power.
Sure it will - sooner or later.
My guess is later; the fine abrasive particles of street dust will need a long time to attack the frame significantly.
Using tires equal or below 1,35".
No…it’s just…too less space.
Yes, and more: The axles and the joints will also move (slightly).
Please imagine the most common bike frame, the diamond type:
The frame tubes could be seen as three triangles; one triangle created by the main frame tubes and two additional triangles for the rear axle.
Note that the corners of all three triangles are 100% stiff (not moveable)!
And now imagine a Strida frame:
It’s just one triangle and moreover that - the corners are flexible, all three in at least one direction!
If you take a look at Ming’s safety pages you’ll notice:
Don’t ride over stairs
Don’t stand up while pedaling
No wheelies
Why do you think they warn about doing things which a common diamond frame wouldn’t take care of?
Hmm…because they do know their own frame?
However…a while ago I’ve bought a few 18 x 1,35" Marathons, shortly before they were discontinued.
Of course you may have a pair of those; just pm me
Hey guys, I recently saw these on Instagram and I am really interested:
8H185BOP-PA PACER
Panaracer Pacers compact 18x1.5
Question is where to get these in the USA?
Update: I found this retailer that ships to the US, ~$66 shipped for two, a little pricey alexscycle.com/tyres-tires/c … mpact.html
As you can see in this post; some Strider’s are using 1,5" width without having trouble.
I saw an 1,5 inch tyre life just one time, and this was touching the frame minimally.
It’ll be a game - either it fits or not
I found the marathon’s in 18x1.35" on ebay but $52.78 US? seriously? My wife would kill me if I spent that kinda bread on bike tires. That is the same price US as full sized auto tires with all the materials, engineering, manufacturing and safety requirements built in… something is odd here.
