Same as TRS RR but not the TRS Gold, think they are billet titanium or something.

 

Its a good job its not or it would double the price of the bike ............I think it may be Kryptonite .....anyway its called the Evo 17 caliper as a model designation........ the mono bloc in the pictures put up by heffergm of the 2019 GasGas show the old style standard mono bloc caliper .....this is not the same as the one fitted to the TRS Gold .......The 'Evo17 caliper has different screw in piston 'caps' ......as in the key shape for the removal tool is different than the TORX like caps that are shown in the picture.   it is CNC machined more rigid lighter blah blah blah blah ......" Free to those that can afford it and very expensive to those that can't".

Blimey just how fast are these trials bikes going to be? Do they really need a monobloc caliper, rigidity and feel at 150+ mph maybe so but perched on a rock about to drop 10 feet does this require such precise braking effort? Strikes me that the manufacturers are struggling with things to grab new sales, fancy stickers and now racing type calipers. The calipers will be so powerful that stoppies will be a problem and disc attrition will be the order of the day.

Being able to lock the front wheel solid instantly using only one finger on and off during a full days competition requires a seriously good caliper as part of the brake system.

With Bultaco brakes you’dneed to stick yer foot inthe front wheel to achieve that sort of stopping ability??

You can  lock the front wheel on most disc braked bikes using one or two fingers be it a supersport or trials bike....eithout monobloc caliper/s. Not looking for a war on words it just seems way OTT ?

There will be no war...........a brake that vicious is something that the top riders require as it makes hopping the rear end around much easier or in an indoor trial when they prop their tyre up against an obstacle with the front raised or are wedged high up straddling two objects etc .......its very desirable to have a brake that OTT if you want to ride using modern techniques.....People who want to learn and execute  the same techniques naturally want the same kit to make it as easy as possible ....everything about  modern trials bike design takes trick riding into account and the caliper design is no exception. The mono bloc super rigid brake will not be considered over the top by those that do a lot of trick/precision riding.  "Does a trials bike really need such a precise braking effort" ?  https://youtu.be/nq_HRNQg07s?t=3m37s ......I suppose it depends on how precise you need to be, bearing in mind all braking power is normally only being generated by just the strength of one finger.

This explanation is the exact reason I asked the question in the first place.  Ever since TRS came on the market people rave about the brakes and the braktec callipers at a glance look universal.

 Agreed, Anyone else notice Bou and I think Fuji, both run the old tried and true AJP front calipers and not the newer''Breaktec''??

Yes; both with the use of a different master cylinder[to obtain more clamping force for less effort of their braking finger] Bou with a Brembo [or Nissin 11mm] 10,5mm piston and Fuji using a Nissin 11mm m/c over a 9.5mm Brickemtik m/c.

Lots of calipers will provide braking to the front wheel .......https://youtu.be/YrZVa7sz4eo?t=1m43s  Front brakes used to  only have 2 pistons not 4 pistons;  from manufacturers such as Brembo  Grimeca and JPA [ Now Briicbrac] ,,,and they worked as can be seen in the video .....

Its not a case of brakes  working, in the case of the Brickbrok Evo17 special more rigid alloy CNC machined ,lighter pistoned calliper it is the the fact that it helps make the front brake lock solid using less effort from the riders finger .......if people do not need that type braking then its of no real interest to them. The brake was developed with Adam Raga who also when at GasGas as their supported rider  was one of the driving factors behind shaving weight off the GasGas and so trials bikes went from weighing over 80kgs to around 70kgs wet ....all to help with his trick riding techniques.......the reason why certain people do not see the value of such things is that they do not ride at such a high level or are not trying to ride at such a high level .......but if they were then they would understand the advantages.

At clubman level trials a Francis Barnett with  drum brakes can beat a brand new Beta Factory Evo    At National and International Level the bike could not compete even if it had more power and was allowed to enter and some one wanted to ride one at that level it could not happen.and brakes is just one of the reasons.

There is an argument against every thing that tries to help a rider reduce  fatigue and effort required to ride...Helmets do not need to weigh 950g lots of people wear helmets that weigh 1200g .....Back in the 1950's  brakes were so poor and bikes weighed so much; making braking even harder that riders were forced to wear flat caps that weighed only 200gms in order to save weight. I

In conclusion most  average  club riders riding a clubman route do not even need disc brakes nor a bike that weighs as little as 70kg  or a mono shock  rear suspension ..........all those things are needless developments for a rider that  rides up and down a few small bankings on a Sunday. https://youtu.be/WEZljnqiUg4   They seem to be managing quite well.

https://youtu.be/IpRVJ83gP0I  Clubman usage of the front brake and club sections in the UK and thenTrial GP sections where it can be seen that an excellent front brake makes light work of flicking the back end of the bike around[so what if Bou's caliper is a split bodied AJP and not a Brikbrak Mono bloc what matters to the user is the ease of use whatever make it is https://youtu.be/2jyqxR2D9r0

"A brake like this"? ....https://youtu.be/jw9IoBHPn-Y?t=12m10s ......"Yes please"
