French noob

Hello, I live around Paris in France. I have a street/dirt/downhill riding background experience, but these days I really want to improve my trial skills. So I bought this KST Acidrop 26" from the mid 2000's, because it was very cheap.

I can already do some small stuffs like manual (even if it's way harder than on my dirt), back wheel hoping over a step with a pedal kick,  jumping over a public bench, etc.. but I feel I have a some big margins for progression.

What I am currently working on is my back wheel hop technique to stand longer. I feel I am wasting too much energy pulling with my arm/shoulders, so I try focusing the effort on my legs but it's not that easy. Do you have some advice or tutorial to masterize this technique ?

Thank you very much.

Another question : I feel I am struggling with my old free hub with few engagement points. Do you think it would be interesting to upgrade ?

Here's links to some Youtubers who have playlists of tutorials, so should find something here!

Re free hub, one of my bikes has a Shiman XT freehub and it's horrible for trials due to so few engagement points.

I have a KST acidrop at my parents place.

Years after years I updated it with used parts or parts from previous bike and now I am really satisfied with the result.

The first change I made was the freewheel for one with 60 (or 72 can't remember exactly) engagement points.

Later I swapped the fork for an inspired (save a lot of weight here), bought a shorter stem (60mm, the original one is really heavy), a higher and wider bar (760 wide with 75mm rise) , some new cranks (shimano XT) and new front wheel ... I think the frame and the rear wheel are the only original parts now. So it might sound strange to swap so many parts, but it did not cost me that much, as I took time to find the right used parts or because I reused part from others bikes.

The bike is now a good street/trial bike, but it fits better for street moves or in the skate park. I really enjoy to ride it!

Thank you very much, that's the kind of advice I was looking for (I'm interested to see a pic of your bike). I still have a dirt/street 26" (dartmoor two6player) to play with and I thought it was more convenient to keep the kst in full trial specs, to focus more on trial moves. But, yes, I feel really much more comfortable on my dartmoor on bunny hop and balance. Maybe I should try to swap my stem/handlebar to keep with something I already know.

Sorry, I don't have a recent picture.

Here some of the parts:

  • stem : pro koryak 60mm
  • bar: ergotec riser bar
  • fork: inspired element
  • front brake: shimano deore m615
  • front wheel: mavic something
  • front tire: kenda kranium
  • rear tire: maxxis holyroller
  • crank: shimano xt m760
  • rear brake: deore v-brake with old trial brakepads from heatsink
  • saddle/seatpost: khe combo

The most important for trial is to have the right gear. I use a 22/18t on this bike.

Wow, there are some good deals for the ergotec. I already have a front disk brake, a tall handlebar and a 60mm stem on other bikes. I will try to set them on my kst to give it a try before buying parts.

I feel can also save a ton of weight on trashing this old squared bottom bracket.

I received some new spare parts : fork Echo SL, freewheel 108 pts, chinese shimano crank. I am waiting for my stem/bar and the trashzen's book

I put the old fork on a scale and, wow, 1450g so I just saved something like 700g. That's massive and I can definitely feel the difference riding it. The bike feels lighter. It's less stiff, so I am really comfortable on. My arms are less stressed doing back hops, I can longer ride my bike, etc..I am already seeing technical improvements (hop to rear on small rocks and transition). On the other hand, with the new freewheel, It's better, but It's not night and day.

I am now practicing my static hops (I can already pass sidewalk steps but not much higher).

Here is the final build with the new cockpit and few other old parts waiting for this rig. It rides like a new bike. I am now preserving my back when I pull manuals and bunny hops, it feels more like my dirt. Now, it's time to practice more and more.
