I got mine earlier in the week and installed it on a KH24. Yesterday was the first real test with our annual Lake Norman State Park ride, here in North Carolina. It's a MTB trail that snakes under the trees in the northern end of the lake. It has uphills and downhills, but not too steep. It's some hard packed soil, few rocks but quite a few tree roots.

Having read LanceB's review, I had done some experiment with the pressure prior the ride. And settled at 17 PSI - I ride the Duro around 14 I'd say. I almost lowered the pressure at the beginning of the ride but I'm glad I didn't. As said, the tire has thinner sides. I'm far from being an expert rider, but two or three times, I felt the tire folding when going through a tight hair pin bend and realizing there's a rock to avoid and you "force" the tire to steer sharply. Lower pressure and it would have been a problem.

I couldn't tell if the tire auto steers more than the Duro because I've never ridden the Duro here, and the trails I'm used to are more flat. Here, because it's on the flank of several small hills, the trail is rarely flat, so you are always changing your balance to compensate.

The weight difference is very noticeable. Also, I had no brakes on that uni, and the whole thing was sooooo much lighter than my usual 24" setup. Which was very enjoyable.

I love the Duro because it's like a tractor tire -we were joking yesterday that you could almost forget to put air in it and it would still carry you-, it's very forgiving and ploughs through anything. But the Big Roller is a very enjoyable tire, great for my skill's level. In short, it's a great and welcomed addition to the small range of muni friendly 24" tires. I love it, and at that price, it's a no brainer!

I agree! The Duro is a great tire, and is the "workhorse" of the muni world (especially 24"), but this lightweight newcomer is a great addition to the group. Since riding styles and trail conditions vary so much, having options is very nice!
I had a longer ride yesterday in a hilly area, about 6 miles with about 2000' of climbing. I enjoyed the lighter weight on the uphills!

Just to follow up on the Big Roller review, I ended up going back to the Duro. The light weight of the BR is great, but I got tired of having to concentrate so much on making it go where I wanted it to go. I didn't fully appreciate the sturdy, reliable tracking of the Duro before, but I do now. So now I just suck it up and plug away on the uphills, knowing that the ensuing downhills will be predictable and fun.
Everyone's riding style and abilities are different, and there are many different types of trails, so I don't think my personal experience should count for everyone. Fortunately, this tire is cheap enough that it's not difficult to try it out for yourself, and see how it goes. Cheers!

Hi have noticed that there are two thread patterns available for the big roller.
One of the two seems aggressive enough for some easy muni with driftings, the other is not interesting at all.
Which one have you tried?
Also, does it feel more air volume than the duro?

24 tire

PHP Code:
[PHP
[/PHP]Yes it definitely feals more volume, wrinkles at 18- 25 psi nicely. Lower rolling resistance at those pressures . No where near the sence of gash resistant sidewalls, but at nearly half the weight and easily available? I have only had it mounted up a couple weeks. We will se how it holds up?

I can't figure out how to load a picture.

I posted a photo on my earlier post on the previous page.
Yes, the tread is fine for muni, I'm pretty sure it is intended for a younger/smaller person's bmx/mountain bike. I wouldn't recommend big drops with it. Maybe it would be OK, just my opinion.
I think the volume is about the same as the Duro, but since it has softer sidewalls, it may seem like more.

Big roller

I rode a couple miles today on this big roller tire. Found the crown of the road or slope of trail dictates the direction way more than the Duro or the Gaza tires I normally use. This big roller climbs the crown or angle of slope fighting you to go straight. I found it frustrating just to go straight. On the plus side the tire rolls well, is nice and cushy, is lighter, does not hold mud or rocks much.Not giving up Just haven't found the magic psi yet. The Duro and the Gaza are hard to beat, with the Gaza being my favorite!

Big Roller - Tubeless, drops

Thanks to all for the reviews on the Big Roller. I got one and have done a couple of short rides. I have a couple of things to add here:

This tire shines at higher pressure (than the Duro) - it is nimble and responsive for me at around 18 -20 psi or so - any lower and the thinner sidewalls are too soft and self-steer a bit.

This tire can handle sizeable drops. I took it off a 3 ft drop a few times (at 18-20 psi) with no pinch flats.

Specialized appears to have used a tubeless compatible bead on this tire. After getting a thorn-induced flat, I set it up tubeless using gorilla tape and a Stans Downhill strip on an Alex DX32 rim and it is solid - no burping yet even on side-hops and akward landings (at 18-20 psi).

This tire makes a decent urban tire. I use my 24 for mostly urban/trials stuff and the occasional muni ride - this tire work well for that mix. The tire also does well on hard pack and loose-over-hard. It did better in the sand than I though it would, but not quite as well as the Duro.

Its not as springy as the Duro or the Berm Master, but its springy enough and the light weight makes up for it on jumps.

The tire seems to have slightly better grip for muni if you run it backwards from the recommended direction. It is slightly smoother on pavement running it the direction its supposed to go.

Follow-up to my review above after a few more rides.

1. Tubeless riding:
The thinner sidewalls produced more noticeable fold-over when tubeless. I transferred it over to a wider KH rim (47mm vs 39mm for the DX32) which helped a bit, but still not perfect. The KH Rim leaked a bit more b/c the Stans downhill strip is a bit narrow for this tire.

2. Muni in Sand / Loose Conditions and Climbing:
This tire dies in loose / sandy conditions. The small wheel size combined with the low knob height and higher pressure (due to thin sidewalls) causes the tire to dig and slip in sand instead of floating and gripping. you definitely want the Duro (or a bigger wheel) for sandy / loose. My previous review was a little more optimistic, but I didn't ride it in deeper sand (>2").

the tire is a decent climber due to the light wieght, but has a tendency to slip on loose-over-hard due to the smaller wheel size and higher pressure.

3. Urban Riding:
The light weight, low knobs, and higher pressure needed for this tire make it a decent urban tire. The flatter profile and knob pattern grips more than the Berm Master making it better on slippery surfaces, but worse when turning on blacktop.

I think the ideal setup for this tire is with a tube on wider rim (KH) to provide bounce and stability. This tire is most at home on hardpack, lose-over-hard and urban environments. It would make a great all-round tire for riders under 175 lb who mix urban and muni, and don't ride in loose conditions.

Whew - enough said on that tire.

Just a note, a tubeless specific rim makes riding tubeless amazing. I've ridden tubeless on a KH rim and it was horrible to me. I eventualy switched wheel size and rim and tubeless is probably the best thing I have ever done. I love it.

I first went with a Velocity Blunt35, and then switched to a Derby Carbon rim. The Derby holds better because it has a nicer design, but the Velocity was all right too, I only burped once!

Agreed on the tubeless specific rims - I wish I knew of one in the 24 in size. Tubeless is a necessity for me. Where I live, If I roll over something alive, its either a snake or it has thorns.

BroncoJohn68 said he had good luck setting up the Big Roller 24 with a split tube style tubeless setup. Haven't tried it yet though.

Schwalbe "Smart Sam"

Bought this tire for my newest, 24" unicycle. Tried to make the uni light as possible: Impact 24" frame (with the new, smaller, lighter bearings), Exceed titanium hub, KH rim, Impact Naomi seat, Venture 150mm cranks. I was really frustrated with the lack of 24" tire choices after spending a few hours reading the forums and looking online. Wanted to keep the weight as low as possible. So, I settled for the Schwalbe Smart Sam. I've done enough miles on it, I think, to write a review.

Width: Smart Sam is only 2.1" wide. Turns out, that works pretty well for the off-road conditions in SoCal. Riding through sandy spots is doable, but requires better technique, specifically that I keep the unicycle under me at all times. My major concern about width is the relative narrowness of the tire compared to the relative width of the KH rim. The rim is going to get gouged, I'm sure, but hopefully not badly enough to cause a problem.

Wear: It is a "performance" tire, which means, I think, that it's long-wearing. Compared to the Ardent on my 26", if I try to ride up a curb without hopping, the Smart Sam is more likely to slip. Perhaps the longer-wearing rubber doesn't grab as well. As we know, everything's a compromise, and the more frequent losses of traction on my 24" with the Smart Sam are mitigated by the lightness and ease at making quick adjustments (and the maneuverability of the light setup in general), allowing me to avoid a UPD.

Weight: Smart Sam weight only 515 grams (I'm being a weight-weenie about this unicycle). It has a wire bead. Responsiveness is important to me, and the relative lightness of this tire provides very instant feedback to the pedals.

Pressure: I weight about 210 lbs (I'm afraid to weigh myself after all the holiday eating). I played around with the pressure of the Smart Sam, and have settled on 36-37psi for mixed-conditions. This is pretty hard, but it avoids folding and wobbliness, and probably helps to protect the rim. If you're used to a DH tire like the Duro, you would have trouble getting used to the Smart Sam.

Flats: I had a series of flats in the first few weeks of riding. Not sure why they happened, but thorns are a major culprit in SoCal. Haven't had any problems lately. I told the LBS about my thorn flats; they suggested going tubeless; then I remembered I have the KH rim with the holes in it. Oops. Not sure I want to deal with the mess of tubeless, anyway.

TPI: I have no opinion about this. The Schwalbe web site uses "EPI" (ends per inch) and the Smart Sam is 67 EPI.

Tread pattern. Looks like a MTB tire. I don't know much about this...

Overview: On a mixed ride, Smart Sam is good in a variety of conditions. Probably avoid this tire on wet or sinking conditions, or if you're constantly running over roots. Given the long-lasting compound of the tire, and that I run it at moderate/higher pressure, it feels pretty good on blacktop or pavement, not too grabby. It is quite twitchy (with the light setup) off-road. Climbing a steep, single track trail, it's both easier and harder to manuever. Easier becuse it pivots and starts/stops more easily when I want it to, harder because it does the same when I don't want it to. Smart Sam is not a serious tire for any specialized purpose, but it doesn't totally suck, either, at a variety of stuff, at least for a middle-aged rider like myself who doesn't bomb down technical hills, do large drops, etc. I bought the tire primarily for lightness, and all things considered, I like it.
