Gt Trials Prototype Dream Build!

Gt Made a few Prototype trials frames for their team riders, sadly they never put them into production. Somehow The Cute Thief got his hands on one plus some parts and I had the pleasure of putting it together!
BIG thanks to Aaron Lutze for actually supplying the frame, please go check out his awesome channel here: / @superridertv
Also a big thanks to Trialtech for supplying a few of their cool products too!

Honestly, watching your videos is so much more entertaining than pretty much every other bike channel on YT, the humour, the Cute Thief, the thwacking, and just seeing a pro build some truly unique bikes, it all comes together lovely.

[@jeremynorth]

Well written commentary too and great input from your cat

[@Ali_Clarkson]

Glad you liked it!

[@SinclairBikeTrials]

YES!!! The head stem thwacker is still around!!! Welcome back woody!!!

[@kamilkempl7121]

About inner tubes. Try schwalbe aerothan. Ive been using them for about 7 months so far. They are 80g instead of standard tube 200-250g. You can not make snake punch with them. And funny moment. It can be used with tyre sealant for protection from small punches. But be careful with schrader rim holes and presta valves. Rim can make a punch at the bottom of a valve

[@Ali_Clarkson]

I think it would work well with this year tyre to save weight but I punctured one in the front on my first ride when I last used them

[@spammy3164]

​@Ali_Clarkson how do tubolito tubes fare? There's also the cheaper but identical ridenow tubes, haven't had any problems using them on my dirt jumper?

That is a beautiful bike. That polished finish is the envy of my childhood. I could only afford the painted dyno vfr but the cool kids had polished GT frames. Also like the shirt. My wife just got me the same one for father's day. Stem looks a bit too tall.

[@alidigitaly]

Add a little air to the tube before placing it so it snugs nicely in place and prevents getting stuck between the tire and the rim.

[@Ali_Clarkson]

I always do 😁

You lucky dog! I tried winning a bid on one when Kenny Belaey was donated his for Hans' Wheels-4-Life charity eons ago. That is a brilliant looking bike.

Just last weekend we had an Observed Trials Magazine slash 180 Magazine reunion up at Everstoke in the Lost Sierra region af California. I'm pretty sure Mr Lutze was in the Mag at least once. I had the honor of a 180 cover doing an X-up adubaca on the Portland waterfront. It was great seeing Joey again and almost all of the crew.

Great to hear you guys are still riding. I live at Rampart Range nowadays riding electric enduro and trials emoto.

[@skyseasun_333]

Out of all the parts to choose from...you chose everything I wouldn't. That frame deserves better. Actually...GREAT BUILD! CHEERS!!!

[@Ali_Clarkson]

I’m confused 😂

[@DomBedford1]

Awesome build! Gives me happy memories of my GT team trials bike i had way back in 90's made famous by the legendary Hans no-way ray, just way smaller obviously!

[@gigakernel]

Valve going sideways is easily fixable! You just 'pet' the tire in the desirable direction before inflating (given the tire already sits on the rim properly of course). And thanks for the most enlightening episode in history dude! ps: you can rub a soap bar on the stubborn place to sit the tire. Also, many gas stations offer free air compressors (instead of soap. there might be some trickery with valve compatibility)

[@fab_89]

props to ct for bring by those nice parts, really a smart cat.😼 liked the idea with the rim tape, overall a really nice build. 😋👍

[@JK-zq9vw]

I really want a trials bike. Never even heard of trials riding and such a bike growing up. As a kid I wanted a GT performer, now I’d really like to get one of these. 😂

[@YanDoroshenko]

Thank god. I was actually thinking Ali the Madman would run it tubeless.

[@deslomator]

Lots of interesting technical commentary and almost free of background music: brilliant.

[@MonkeyShred]

Spot on mate. The polished alloy finish is top notch 👌

[@skizzarz]

10:45 you should say they weight you saved is rotational mass at the extremity of the circumference which actually helps fast acceleration for lurches more than you might think (at the risk of sounding geeky)

[@houseofsolomon2440]

I wonder if angular acceleration get in the mix(?) 🤔

[@josefbuckland]

ITS ALL THERE! Like a perfect concept like Holdens Marilyn or Efigee. Stay safe.

[@oleg..]

I have this exact freewheel on the fixed cassette hub of my polo bike. No noticable drag, and all the noise you could ask for.

[@Sunspot-19]

I still enjoy my Red Sky, Ali!! Stealth mode is a default cause disc brakes are silent. Noisy brakes are not becoming of a bike of a Red Sky's stature!!! Automotive coolant was a thang!

[@edstorey4675]

I never knew why exactly rear t tires were so finicky to inflate, I mean I do it , but your eplaination of WHY is excellent. Also great reminders WHY t rear tire characteristicsare what they are. Thank you !

[@dimensionsofearth]

This is a monumentally nice looking bike! It does look strange with only the back wheel mounted, a trials bike isn't much without the front end! Aaron Super Rider is cool, I've watched his stuff and even saw a live stream with him and Ryan Leech. Plus 70 sounds sooo high too, wild.

[@gerthinatorgaming5952]

That is one stunning frame 😘👌 I've always been a fan of polished GT bikes.

I'm rockin' Schwalbe "Billy Bonkers" tires on my 24" BMX and really like 'em.

[@plasmar1]

interesting that you mention rim breaks are still the better option(for 26"; I dunno how broadly you meant but suspecting it still applies), I converted 2 of my bikes(mountain) to ebike and was considering switching to disc and despite not having tried them; I was having a hard time convincing myself switching was worth it just thinking on how fast I can stop each bike on rim breaks and the amount of material on the pads

[@ashleytombs]

Well, ### damn! They even managed to retain the hallowed, vaunted, legendary, crucial, 'triple triangle'! lol Cool find ~ love the headset install btw 😂

[@canardweb]

Hello Ali, amazing frame, it's a shame the chain rubs so much, Kenny complained about it a lot when he was riding it. However, please don't ride that stem, Dominique never bothered recalling them but they were always failing at the ring area, and cracked where the bolts are tightened even when using the right torque. Koxx even provided free spare rings to people who had broken them. It's a shame as the original prototype which was teased at Koxx Days in La Tour de Scay wasn't exactly made that way. Also mind the titanium axles of the Echo pedals, loads of lightweight riders have broken them. I have a question though: isnt the paint stripper bad for the caliper's seals ? Great video, keep it up!

[@peglor]

I've broken the bodies of the Echo pedals too. They're definitely not suitable for riders over 80 kg to use for any length of time, but then I've also snapped the axle on a Hope pedal - my own fault after I 'retired' it to my trials bike for a couple of years, after at least 15 000 km of hard XC/Marathon use. I was doing a standing wheelie up a ramp at the time and when it let go, the completely blunt stump of the pedal axle ripped the skin at the side of my knee open 😞. Very little pain but it took a few hours to stop bleeding.

[@canardweb]

@@peglor it's not the body that easily breaks but the Ti axle.

[@peglor]

@@canardweb I've broken the steel axle on an Echo platform pedal, but both me a a friend of mine have broken the bodies on the Echo cage pedals. I wouldn't go near Ti axles on anything because they're weaker than the steel ones I'm already breaking. It's always metal fatigue incidentally, not straight overloading.

[@hellopsp180]

I like how you grind your Brakes. Velcro fabric :( @ 27.39 - I would have put a rubber surface stuck onto the tube instead of the fabric. It should be less friction and the sound should be similar

[@johnoregan4221]

Wasn’t this designed with Kenny Bealey in mind? I think I recall him doing a short stint with GT. Rad build, I was super excited when this prototype came out as I thought a major brand was getting back into having a trials bike as part of their line up. Shame it never went into mass production.

[@tonymighalls9667]

Tidy build that Ali! Thought you were gonna say you had borrowed it off hans rey, nice of super rider to send it your way! 🤘

It really needs to said that the greatest risk with Hydrogen gas is it’s highly explosive so NO FLAMES while dipping aluminium.

[@florindocaraballo5516]

Sweet.👍👍👍👍

[@AquaticBaboon]

The biggest difference I remember when switching to a front freewheel setup was how much lighter the feel was for rear wheel hops. Since you're no longer moving the chain when ratcheting back it takes less effort and feels more snappy. It was a bit unnerving watching the chain whirring at mach speed while riding between spots tho

[@BTB_Works]

Come on, Ali, just give in! don't regrind the rims, just smack some tar on there! :) And as for the usage of front freewheels, it's mainly cost, I would have to say. It's way cheaper to manufacture this many engagement points in a bigger housing, compared to the small space offered by a rear hub.

[@Ali_Clarkson]

But I might want to ride it in the wet 😂 I’m going to disagree with the ease of adding more engagement points though, freewheels are actually quite constraining…the outer diameter is fixed by the teeth count, the inner diameter is fixed by the thread/spline size and the width is limited by the frame/bb width. Hubs are usually smaller just because they have weight/manufacture concerns plus most MTBers don’t worry too much about the strength of engagements but there’s nothing really to stop a hub manufacturer from putting an absolutely huge ratchet and pawl system in

[@BTB_Works]

@@Ali_Clarkson yes, buuut, there is more diameter, aka more space :)

[@Ali_Clarkson]

@@BTB_Works nothing to stop a hub having the same diameter or bigger though

[@BTB_Works]

@@Ali_Clarkson true. Just imagine, a hub with the internal diameter of 200 mm. Disks wouldnt flex, axles wouldn't bend...

[@indrekpart277]

Awsome bike. Nois pure trials video incoming? Btw modern mtb tyres and trials specific rims tend to not seat. I could not get my conty trailkings seat at all. 1/4 tyre would sit 10mm deep from the rim bead. Trialtyres only since then.

[@NormanWray-hi8cu]

Hello dear friends yes it's working great 😅😊

[@benpc1794]

I've got an almost new rear try-all tyre in the shed if you want it?

[@Ali_Clarkson]

Thanks for the offer! I actually have one here too but I never liked the rear versions, they have absolutely zero spring to them at all!

[@cliffsangelsphotography]

Another Like for the Cute Theif 👍

[@gg4760-k5n]

why not using TPU inner tube ? You could get nearly the same weight than tubeless while still having a tube.

[@Ali_Clarkson]

I think that could be a decent option with a thick heavy tyre like this, I have used them in the past though and they rarely survive my first ride

[@ehrenkrause9861]

No I've never did like the threaded bottom brackets even on mountain bikes. Cuz once you strip them out you're pretty much screwed

[@orenchip]

[@syukrontrials]

[@robertcasey1708]

What if the angle of the steerer tube was not cut perfectly? Wouldn't you be stuck with a misaligned stem due to the sloped topcap? Seems like an ultra high risk to me for marginal benefits.

[@Ali_Clarkson]

It doesn’t need to be 100% accurate, just close enough to give full clamping area and not bottom out on the top cap. You’ll still have plenty of adjustment to get the stem straight 👍🏻

[@niteshades_promise]

crank free wheel? 🤯🍻

[@69Deez_Nutz69]

😂 my thoughts exactly, although Shimano did have a Front Freewheel Chainring back in the days but never caught on.

[@jnxmck]

Love it! If you ever want rid of the frame then I'd like to cash in the favour you owe me when I sent you that Echo frame a few months back and get first dibs ;)

[@xyrius]

Strip club :))) Awesome build! I have a couple of recommendations/questions based on this particular build. What's the point of tapered forks? I mean in reality are there any problems with standard/old forks? Also about fork/frame material. I recently had the oppurtinity to buy a Tange Ultra Light fork it's about 20 grams heavier then the aluminum Trialtech you used int his video. I don't really understand why cromo forks and frames are out of te game they weight almost exactly like aluminum, but they are more rigid and durable. I know that you're not a fan (to put it mildly:D) of Magura rim brakes, but I think they have many advantages against disc brakes. My question is what do you think is the best pads for smooth rims? Without using tar? I'm around 60-65 kgs and I think the stopping power of Magura breaks are in conection with the rider's weight. So for some poeple they're ideal for some people they lack the stoping power. And the last one, once it would be very interseting and educating to see a video when you explain which rear hubs (for rim and disc brakes) are suitable for trials and why.

Would love to see trial tech doing miles more parts again, was always the strongest stuff and seemed to always "just work" no matter what, quite so with try-all as well. Very little choice or stock for parts in the trials world these days, both very unfortunate and not too good for the sport 🤔

[@Ali_Clarkson]

That’s a god option for smooth rims (though I prefer tar) but a grind simply can’t be beaten especially in the wet!

[@xyrius]

@@Ali_Clarkson Silicon brake pads for smooth rims are awesome until they get dusty. You can use some water to clean the rims and the pads. They work great in dry weather, they have modulation in contrast to tar. But in a wet environment the only option to smooth rims is tar. I think it's a shame that there are no sintered or metallic brake pads available for Magura rim brakes.
