DT swiss's new hub has 90 engagement points and uses a similar but bigger version of the current 240's ratchet. With a 18/15 transmission it shall feel like a 108 POE front freewheel. The DT swiss star system is amazing, it feels less spongy than other systems and is really light and reliable. Too me the best system. It seems DT swiss won't currently offer a singlespeed version though 😐 Would be nice on an Enduro bike.

Nice to see your videos are back! The first line with your street trials is amazing! I did not expect the bar spin. The one at 3:24 is so smooth, no extra hop, Manifesto style 😍

It seems also that some hoses are stiffer than other. Goodridge had a good call. But even with stiffer hoses, there will always be a difference. Even with V-brakes and linear cables I can notice a slight difference. Maybe you have also more forces in your right hand too.

Ali experiments with head angles. @Ali C: Do not forget that the lower part of the Slack-R raises the front of the bike of 10mm or more. It is like riding a fork with a10mm higher A2C. This slacks the head angle from 0,5°. But still your bike head angle should be around 72°, not 70°. Is there maybe a difference in A2C between the pro fork and the team fork? I don't think so, but who knows. I guess one further drawback of having a slacker head angle and thus longer wheelbase is that the rotations are harder to execute. Did you try some bunnies 360°? What about static hook? You are right, Flatland BMXs have really steep head angles. Matthias Dandois rides a 75,5° currently (Haro La Bastille).

I don't know the brand from the pads, I got them with a brake. I thought they were Crewkerz orange ones, cause they are translucent. I think they are my favourite pads. I love the feel and it seems to me they are better in wet conditions than the Coust one.

Some more pictures:

Hello, recently I was looking for a cheaper bike with a front disc brake. I found an used Atomz Quark II for a good price. It is a medium size. Two years ago I bought a small one after more than 10 years without comp bike. I could not really appreciate the small one, cause I had basically no reference to compare to. So after riding different bikes (cleep, jealousy, freed), I was looking forward to find how good the bike is. Even if the bike is more than 10 years old, it rides really well. The geometry is not too far from a cleep or a jealousy, only the bottom bracket is 15mm lower. It had already a through axle and built-in tensioner. It seems to me that the bike is less stif than the cleep and less reactive. But is ride really well though. It is overall a solid bike. The carbon plate to hide the HS33 hose was missing so I built a smaller part from Kydex. I think I will swap the brake lever for an old 2005 HS33 black one (the current one is from another bike) and the Louise lever blade for one with TPA. Hope you like it.

Thanks for sharing. I follow a few Asian YouTube channels, they like to ride comp trials and/or natural grounds, it is nice to watch. Will post a list of them maybe.

I don't think they will. The market is saturated, so many brands currently and I have the impression street/trials has no longer the momentum it had a few years ago. In Germany and France, the used market is full of 24" street/trials. I think the fact that Danny and Fabio do not release any street/trials edit anymore and with the rise of e bikes, there is less interest in this discipline (sadly). I guess it will be like Danny's Santa Cruz or Duncan's Marin. I heard some rumors alledging that Fabio's frame is released cause it was part of his contract. Hopefully I am wrong and the big S will become a new major actor.

Hi, Tartybikes has developed its own range of products! The brand ist called RD: https://www.tartybikes.co.uk/news/tarty_bikes_launch_a_new_range_of_products/u330.html Love the use of steel and laser cut (think Adam already knows the French brand Boulhol) and the development of lower price components. (some v-brake adapters are upcoming) Such a good news! Thanks Tarty to launch a new brand in this tough times! Wish you the best!

Hi, Good to hear you did not get bad injured. Did you notice some scuffs on the chain? Months ago my chain broke regularly and I then understood it was related to some hits on the chain (I had no bash at that time). I just swapped my chain and bought two Z1HEX. I run one of my cleep 26 for many months no, but I don't ride it currently as much (somehow it is refreshing to ride 20" ) I also tried a Izumi 410 chain, used in track racing and black on my street trial. No problem with it neither. I noticed there are now a KMC e101 and z101.

Hi, Cheap with 72 poe... My answer would have been Hope. It is quite a lot for MTB... Yohan Triboulat rides a Spank Hex hub and he seems happy with, more than with Hope. The hub is slightly less expensive than the UK made one. Why not an old pro 2 evo? It has 40 poe but with 4 pawls engaging simultaneously. So you could shorten two like Tarty did? But you know already the trick I guess. 😁

Thank you to Rich, Heatsink and the participants! Trials needs more of this kind of contests to get more visibility overall. And the riding on these bikes was fantastic and proved again that the rider skills are more relevant that the bike!

Love the first glimpse of purple😍 Look forward to see the result and to hear about your riding feedback. And let us knowhow the Comas hub works.

I forgot one thing: I have the impression it is more difficult when the bike and application are too close. For example I had more difficulties with a 24" race BMX than with a 20" on a pump track or race track where I used to ride a 26" bike. I had a similar feeling when I tried the different 24" street/trial bikes of my friends. I have a similar problem with the different keyboard layouts I have to deal with (en, dr, fr). I noticed that I don't map a location (home, at work, etc.) or a device (laptop, workstation, private computer) with a layout but more what specific application I am using (what mail program exactly). But maybe that is just me.

Agree with of you. Just want to add my own experience: I had several bikes (currently street trial 26", comp trial 20" and 26", 26 and 27.5 MTB) for many many years. From my experience: - if you switch a lot, you will feel comfortable to a new bike faster. - once you are used to a bike, it takes less time to feel well again on this specific bike - but even after many years, you will still need many hours to ride best with the bike. - with experience, you understand better how to use a geometry best. Overall switching to a new bike helps a lot: it is a source of motivation, it forces you to adapt your position, maybe even to force you to execute moves you won't use else. I currently ride a lot my 20", it was quite weird first but now I enjoy it a lot and it forces to pedal up more obstacles and to be more precise. I think people tend naturally to execute over and over moves they already can. Learning new moves seems to me to be more effective to progress faster.

It is a fully integrated headset? Damn, I don't like them. I had once a Devinci with an integrated headset and the bearings damaged the seat: I guess I rode once with a loose headset. I had to buy a headset cutter and the result was OK, but not as good as from the factory. There is no room for error with those headsets. Hope they won't remove the cups of the bottom bracket shell.

I guess around 2015 the MTB geometries were spot on. I have the same issue as you with chainstays length. I like short ones, but having longer ones makes you ride faster, safer and cornering better. It climbs also much better. I went for a Kona operator 27.5" 2017 to replace my old 2014 26 " summum, to get shorter chain stays. To be honest I am still not convinced that it is a better choice. Only improvement is the bike ability to jump, I feel more comfortable (which is good cause I suck at jumping) - but I think this is mainly due to the bigger Diameter of the wheels. Manuals or bunny ups are not much easier, and I have lost traction in some turns...

I first understood you wrong. Read twice helped. They changed both the headset height and the headtube length, right? Your spokes looks silly on my display : Look at the top left oblique ones. They look like they are not continuous

Some months ago, I tried this: - 90x 35 trialtech stem - high riser street bar (around 100mm rise) The bar/ bottom bracket height difference was similar to the one of my street trials. It felt quite weird and even if the manuals were quite easy to throw, I did not trust myself on high bunny ups. I did not ride enough to get perfectly used to, but I did not find this experiment a success: the higher bar made the weight during rear wheel hops more difficult, the extension to the front was harder too.

You meant head tube instead of headset, right? I really like the fact that they always improve the proven design further. When you look at the history of the Atomz/Crewkerz bike, it is like natural evolution: AKTII -> Quark -> Cleep -> Jealousy mkI -> etc. Some minor changes for each generation. Also having slightly shorter bikes sounds for me better. My 1090mm large Cleep is for my riding level not better than my Freed 3 with 1070mm. On the other side, I found the 1065 Jealousy I tried two weeks long too unstable. Was really nice to have fun with though. PS: be careful with your spokes, they look already snapped on the pictures (how can a smartphone generate these artifacts !?)

I don't know but by the look at the sidewalls ... They remind me my Kenda front tyre: The sidewalls are really too weak and the plies are visible. If you ride with low pressure, I guess they won't last long. But this assumption is just based on the picture.

Hi and welcome, Do not hesitate to post some pictures of your bikes. Guess with a bmx background you should be able to learn the basic quite fast. Wish you a lot of fun !

I agree with you both. I think the concept could be better implemented. And I don't want to spend a single word on the website... Unfortunately I have absolutely no knowledge in biomechanics. But the facts that clip less pedals have angular motion makes me wonder if there may be an advantage. In addition, there are only 4 points of contact in trials and two of them are pedals. It makes sense to try to improve it like it occurs for stem and bar position. And I like when someone comes with a new idea/thinks outside the box. @cwtrials: I see also your point with instability. It seems they use a spring to rotate your feet back. I was thinking about suspension fork: it may feel sometimes less stable at slow pace but overall a mountain bike feels more control at speed. Maybe sacrificing a little more instability could be worth it if other aspects are improved.

Right, I will try to explain my thought. I think having more angular freedom for your feet helps when you cope: - Maybe even more when you cope the bike sideways, cause you put the bike out of axle and you have to twist your ankles. For sure the ankles give some range of motion, but can more angular freedom helps? - In addition, when I squat, my feet tend to twist - not sure if it is the case for everyone, but it is well known that clip less pedals without angular freedom can lead to knee issues. So if they are able to twist freely, maybe I can cope even faster/better/higher?
