I tried lower pressure and it was almost unrideable, so I bumped up to its rated max (36psi/2.5 bar) and suddenly it's fine. It's not better than the fat frank but it's not bad. It turns nicely and is no longer overly affected by camber.

The fat frank on the other hand works well on a wider range of pressures and has a much higher rated max (60psi/4 bar), plus it's lighter. It's also much easier to come by (at least in Norway).

I think the fat frank would therefore be a better option in most cases but if you are willing to have it pumped hard and want something with a different look (the beach bum comes in a range of colours, with and without white walls) then this tyre could be an option.

Since its working ok for me now, I'll leave it on a little longer so I can sport a new look.

Ok, I think I might have jumped the gun and judged the “Beach Bum” too harshly. I went out for a longer ride with my daughter and it felt great now that it was fully inflated. I also tried my short reference route again at speed and actually got around it faster than I ever have on the 26”er (or my 28”er for that matter).

Hmmm… though that could also just be that I am getting quicker with practice, added to a placebo effect causing me to ride faster because I expect to ride faster.

With regards to size, I feel that I can actually see that it is visually bigger than the Schwalbe “Fat Frank” (26x2.35/559-60).

I should start by saying that the Duro “Beach Bum” 26x3.0 cannot really be considered a true 3.0”. This is given away by it’s listed ETRTO size of 559-70. Obviously, 70mm is actually 2.76” (rounded to two decimal points). And you should also consider that this unicycle came with another Duro tyre, the “Wildlife Leopard” 26x3.0, which has an ETRTO size of 559-75. So Duro, Is 3” 70mm or 75mm? Clearly they are just playing around with marketing, as is often the case with tyres.

Anyway, that aside, a 559-70, should have a “theoretical” total diameter of 699mm—(70x2)+599. I figured I’d try and check this and attempted to verify the diameter with tape measure (not the most accurate I know, but it’s what I had to hand). Sure enough, in this particular case it does appear to be pretty close to the 70cm mark.

For comparison my 28x1½ (635-40) wheeled Pashley unicycle (with a Schwalbe “Marathon”), should have a “theoretical” total diameter of 715mm.

This would put the 26” with a Beach Bum at 98% of the size of my 28” with a Marathon. That also helps to explain the relative pace, as the 26” also has shorter cranks (102mm compared to 114mm).

So, I tried a quick visual test by putting them side by side and I think you will agree, 98% looks believable.



So what is my final take from all of this. The “Beach Bum” is actually a pretty good road tyre after all… and… I have probably just made my 28”er redundant.

If you are still thinking along these lines, another option is Vee Tire Co.’s 29x2.8 (70-559) “Plus Size Speedster”. I haven’t tried it but based on the ETRTO size, it is just as big as the Beach Bum and certainly looks interesting. Though it doesn’t come in the range of colours that the Beach Bum does (if you care about that, at all).

I have changed my mind… again…

The weather has finally turned nice enough, and my primary cycle to work route is clear enough, that I dropped the spiked Kenda “Klondike XT” 26x2.35 and went back to the Beach Bum.

It (the Beach Bum) is annoying again. I kind of adjusted to it last time but it really should not be this much effort. I don't want to try so hard and would rather be relaxed when commuting in. I actually really missed the Klondike XT, which is a nice tire for mixed conditions of (a little) snow and ice, while still handling well on bare asphalt.

For tomorrow, I'll go back to the dependable Schwalbe “Fat Frank” 26x2.35. Smaller yes but lighter and requires no fighting.

In my depression over the unsatisfactory cycle in on the Beach Bum, I had another look around at fatter road style tires and found a nice selection on https://classic-cycle.de. They are all kinda heavy since they are aimed at cruisers bike, where the look is more important that then weight. Nonetheless, I am still interested in what is out there. Since I know that I like the shape and tread of the “Fat Frank” I attempted to find something similar. Visually the closest would appear to be the “Super Brick” (26x3.0/74-559), so on a whim I bought one.

I'll probably regret that too but what the hell, I am curious and in the grand scheme of things it isn't that much. Though I am amassing quite a selection of tires now.

Helpful info. Let us know how it works.

Your latest order, the tread pattern is almost identical to my 30 year old Schwinn (the original 20X1.75 tire)

Yeah the brick-style pattern is fairly common on tires of several brands, e.g. the Felt “Thick Brick”, which I see from the images on the Classic Cycles pages, someone has already tried on a unicycle.

Hey you only live once. And 29€ is not crazy at the end of the day, especially if it turns out to be a good tire! Let us know!

Ok, the “Super Brick” arrived. Now that it is here and I can inspect the info on the side, I see that it is an Innova “City Tire” (Code: IA-2236). Interestingly the Innova website says the 26X3.0 is a 74-559 tyre, while the tyre itself states 76-559. No matter, what is 2mm in any case?

The other pleasant surprise, mentioned on the Innova website (and the tyre itself) is that it is rated for 40-65 PSI. This is good because I found that with the Beach Bum it handled better the harder it was but the Beach Bum only supports 36PSI. For the commute in today I pumped the Innova to 50PSI.

So far I definitely prefer it to the Beach Bum. It is lighter (150g lighter according to info on the Classic Cycle website) and rolls more easily (probably due to higher pressure). It is also easier to control (again could be higher pressure or just the even more minimal tread). I do feel it pulls a little to one side but I actually find that with several tyres so I am beginning to suspect that issue is more about me. I might try flipping the tyre and seeing if that makes a difference, since it is not a directional tyre.

For those curious about the size, it looks very similar in size as the Duro Wildlife (as expected), albeit with very minimal tread (and a 580g drop in weight). Here is my 26" next to UniMyra's spare 29" (29X2.1/54-622) to give you a rough idea of size and scale:



I'll run it for a few more days and give a little more feedback again, once I have used it a bit more.

Oh and you can also buy the Super Brick / City Tire as a whitewall version, if someone wants that.

Hmm... It occurred to me that since the Classic Cycles website lets people upload pictures of their bikes, I should get some more unicycle pictures on there, so that we are properly represented. So I put up pictures for both the Beach Bum and Super Brick. In fact they are currently the only community submitted pictures for both products.

So yeah… it is good. I like it. More than the Beach Bum and for anyone interested they have it as a whitewall version as well. In summary it is a nice option for anyone wanting a plus sized road tyre.

Interestingly I rode my old Pashley 28" yesterday for the first time in a long time (I wanted to try it with 90mm cranks) and I realised that the tyre (it's original) has a similar “brick” style pattern as well. Now granted it is a very different tyre to the Innova “City Tire” (Code: IA-2236) because it is so much smaller, but like the Innova it rides very well, and far better than the Schwalbe Delta Cruiser that I once tried swapping it for.

So—note to self—keep an eye out for tyres with a brick pattern when next shopping for road tyres on a unicycle, since I have had good experiences with them thus far.

P.S. 90mm cranks work pretty well on this wheel size (for road riding at least). Though I have not spent enough time to be certain that I prefer them to 100mm.
