I like the break bumps.. it's DIRT people! if I wanted smooth there's all kinds of road to ride.

I don't necessarily like break bumps. I am all for technical trails, but I'd rather that be rocks or roots. I say put rocks in dips of break bumps and it should remain technical, but a bit better armored (as long as the rocks are big enough not to get ripped out).
that being said, I rode the trail Friday and I had no problems. I do know the section he is referring to, there is a banked turn at the end of it. I always make it a point to ride that downhill with reckless abandon. you really don't even need to brake that much at all, which is ironically true of most places that develop brake bumps.

Yep; that's exactly it. I imagine this section is great when smooth or if you can spot a good line. I don't know PLRA very well, so it always catches me a bit, and then it's rough coming into it with the brake bumps.

I'm not sure putting rocks in them would do it, as they are curved in such a way that I think the rocks would get popped out. Making the surface harder overall would help, but without rock... That may take paving the trail. Literally.

If you really like brake bumps, go ride dirt roads in populated areas. Brake bumps and washboard roads (particularly the pothole-ish ones near stop signs) are the same sort of wear. If not mitigated (graded in the case of roads) they'll keep wearing in until they are nearly unridable. This sort-of explains it from a washboard perspective, but brake bumps are the same thing except in reverse (slowing wheel instead of accelerating).

don't get me wrong, erosion sucks. I guess I should have said "I'm cool with whatever the trail throws at me, and I don't mind the break bumps"

Experienced people can, but these corners scare some -- many of whom are the sort to heavily drag a rear brake -- leading to this. PLRA is popular with all levels of riders.


Granted, but brake bumps are usually the result of trail design decisions. Designing the trail so that people naturally scrub their speed before the come into the corner hot will eliminate many brake bumps.


PLRA is in the real need of berms. Lots of turns can be bermed there so people who can't handle turns properly can still maintain their speed without producing brake bumps. And people who can handle turns will absolutely zipp on PLRA. Also, all of those mud spots need to be turned into rock gardens.

Anyone know who strung orange Surveyors’ tape all over the trail a couple weeks ago, and more importantly, why It's still there?

Other than that, the trail has been great the last two nights, with just a few (usual) damp spots. No obstructions.

Pretty dry out there yesterday with the most loose grapefruit size rocks that I've seen.

Loosest I've ever seen it since I stated riding in 08. Pretty fun time.

Who is the trail coordinator for PLRA? The trail has seemed overgrown and some of the Cycletherapy people would be more than able to help during a trail day.

You mean you guys haven't heard? Due to the increasing amount of complaints about erosion and brake bumps out there, the DNR has decided to pave the MTB trail. The orange tape is to guide the construction crew.

Are there any races around this loop? What are people clocking for lap times?
