Wider bars and shorter stem make my XC 29’er hardtail into an all-mountain bike. Kind of.

My Trek Gary Fisher X-Cal 29'er with wider bars and shorter stemMy 2011 Trek Gary Fisher X-Cal 29’er hardtail is going to have to do duty as an all-mountain bike this year because A) I’d like to ride one or more gravity enduros; and B) I can’t afford full squish yet.

So this past week, I upgraded to a:

(I’m somewhat less than mechanically-inclined so I needed a little rescuing from Stew Moyer & Ryan Hutchinson at Mike’s Bikes.)

Mankato Area Mountain Bikers (MAMB) fundraiser on tap for April 19

On tap, indeed.

MAMB Brewery Fundraiser

My mountain biking colleagues Clay Haglund and Doug Janni and their Mankato Area Mountain Bikers (MAMB) club members are hosting a fundraiser next month at the Mankato Brewery. “There will be music, beer, food, games, merch, and a raffle with great prizes from local businesses” says the flyer which I printed out and put up yesterday in a few key spots around Northfield. See their Facebook events page for more detailsContinue reading Mankato Area Mountain Bikers (MAMB) fundraiser on tap for April 19

When I learned about rotational violence to the brain, I bought a full-face MIPS helmet

When I attended IMBA’s Great Lakes Summit back in June, Aaron Rogers, president of the Copper Harbor Trails Club and Trails Specialist with IMBA Trail Solution showed a video about the IMBA Bronze-level Ride Center that had just opened in Copper Harbor, Michigan.

Bike magazine included the video in a June 22 article titled Andrew Shandro at Bronze-Level IMBA Ride Center Opening In Copper Harbor, MI. Aaron Rogers was quoted in the article:

We’ll be building medium- and small-sized jump trails–Flying Squirrel trail is considered a large-sized jump trail–as well as a true flow track to increase our scoring.

Some of those guys going down the Flying Squirrel jump trail in that video (as well as another one here) are wearing full-face helmets.  And so when I started experimenting with the jumps at the Lexington Ave. Pump and Jump Park, it occurred to me: I’m going to like doing this. I want to ride that trail at Copper Harbor. But I don’t want to end up in a hospital bed, paralyzed, thinking ‘Dang! I should have purchased a full-face helmet.’

When I started poking around the intertubes, I discovered that there are new helmets equipped with the Multi-directional Impact Protection System technology, or MIPS.

This June article in Mountain Bike Review titled POC and MIPS Collaborate on New Styles sums it up nicely:

untitledThe Multi-Directional Impact Protection System, MIPS, was developed by a Swedish neuroscientist to improve protection from oblique impacts to the head. Concussions and brain injuries are often caused by angled head impacts that create rotational violence to the brain, causing strain on the brain tissue.

MIPS utilizes either a low friction layer on the inside of the helmet liner for inmold helmets or a low-friction layer between the outer shell and liner for hard shell/two piece helmets to absorb much of the energy created by both unilateral or oblique blows to the head.

POC Cortex DH HelmetBy mimicking the brain’s own protective mechanisms, MIPS can significantly minimize brain injuries in connection with angled impacts and rotational violence. The Royal Institute of Technology (KTH) of Sweden has conducted tests concluding MIPS helmets can significantly minimize brain injuries.

Griff Wigley, POC MIPS helmetOne of my local bike dealers, Mike Bikes here in Northfield, gave me a great deal (considerably better than anything I could find online) on the Cortex DH Helmet from POC (full list price $500). QBP had it in stock and shipped it to Mike’s within two days.

I know, pricey. And more helmet than I really need for my current skill level. (There are other MIPS helmets on the market that aren’t full-face, so shop around.) But when it comes to protecting my geezerly body, I’d rather err on the side of too much.

If I can get the hang of doing the beginner table-top jumps at Lex and Leb, I’ll start wearing the helmet.  I’m hoping to get to Copper Harbor this fall.
