Roller height on the PumpTopia pump track?
Just purchased the Pumptopia Track Plan and was reviewing some of the sheets while comparing some things in your ebook “Welcome to Pump Track Nation v2” and had a few questions.
In the ebook it mentions 12″ high rollers with 10′ from peak to peak for the rollers. However, in the plans it shows 18″ for what looks like 10′ peak to peak on rollers? Is there a reason for this? Will it be faster or slower?
What a great question.
The taller rollers are potentially faster/jumpier for skilled/strong riders, and they still work for regular riders. If you want an easier all-around track, make the rollers 12 inches tall. If you want a bit more of an “expert” track, make ’em 18 inches tall. Or somewhere in between.
I hope that helps,
Lee, I’ve been slowly dumping a bunch of dirt from other areas in my yard near where my pump track will go.
Some of it is clean but some piles have a bit of gravel mixed in.
Have you tried to sift dirt to remove rocks? I know your book talks about not having rocks but also says the best dirt is the dirt you have.
I personally have used a rake to remove rocks from the surface. It’s laborious but does the job OK. In the long term, buried rocks have a way of migrating upward.
Next-level effort would be to make a sifter with, say, chicken wire, then sift all the dirt before it goes onto the track.
Thanks Lee. Should give me plenty to do while I avoid the plagues and locusts going around right now.
Yes! Good old fashioned manual labor.
When I was building a couple tracks a month, I was pretty darn strong.
I found that old post https://www.leelikesbikes.com/pump-track-for-29ers.html concerning roller height and 29ers. Whci roller height and spacing would you recommend for 27,5ers and 29er for PumpTopia to fit that MTBs? I want to build as fast and jumpy track for skilled riders.
