Just done a 20ft high 25ft long natural gap/drop on my .243 with 80mm travel , didn't even clear the landin which was a field for cattle. this is the vid https://www.pinkbike.com/video/104151/ just estimated lenthg at 25ft but just looked at the pics and scaled it and it is in fact 30ft lenght . so it is a 20ft by 30ft gap
i paced out some gaps i did and theyre a bit bigger than i thought. biggest gap was a 20ft step up and drop was 8-9ft then there was the stair incident...note to self: dont drop stairs unless your sure of how many there are (i think there were about 12-15 but thought it was around 4 or 5)
at 16 seconds The biggest drop is 8-9 feet but I dont have any video of that trail because it got torn down EDIT:shit wrong video above heres the correct one
