Slovenia customers - Alert


Unfortunately, because of new findings about unfair practics we have to again warn our Slovenia customers concerning IK Sport and our products. Despite false promises, which we get after our 1st allert published 18.8.2014, no obligations were solved (we moved our alert out from facebook and our websites due promises, but we realized it was a huge mistake to belive all the lies and promises).

So, we have to say again, that IK Sport is not allowed to sell, even service our products! Please, avoid to request that over them, you will save your time and money. We've got information from our customer that they have got somehow revised suspension from them and were informed it was made by us. It is not possible and we're sure, that any service of our products can't be done properly as we do, because all of a components are made by us or developed by together with suppliers (not available for others), also we are using special machines to filling and measuring all the dampers before returns to customer.

So, again, if you have request of just need any information, please contact us on e-mail or +420 723 35 45 74. Thanks for understanding

Our story


The history of our company dates back to 2004. After ten years of racing in enduro and twelve years of experience in manufacturing of sports shock absorbers I decided to start my own business primarily focused on producing top racing shock absorbers with adjustable damping characteristics. That's when I started to develop our first prototype of the damper with compensation reservoir and adjustable attenuation characteristics.

One of our first shock absorbers was used on buggy of Václav Fejfar. Within long years pending development were Protlum shock absorbers improved significantly, resulting in getting customers, not only top drivers in Czech Republic, but also in abroad, like Slovakia, Poland, Slovenia, Croatia, Romania, France, Germany, Austria....


Motto: „We like to win with our customers,
become one of them…"

At the end of the year 2009, we've moved into new place. Within this change we've increased our staff and production capacities. However, still individual cooperation and helpful approach is our priority for one every customer. Our customer are always first, and in many cases they became our friends. 

Besides our own development and shock absorbers production we ensure regular revisions. More and more often we are promoting our customers for activities in case of testing and tuning. Top suspension and proper setting and adjustment of damper characteristic is one of the key items of succes in all of motorsport disciplines, that's why we're proposing also attendance and support due tuning sessions and help with setting searching. Investment for top class suspension is meaningful only with precise testing and tuning...
