650B wheels on a mountain bike

The Bike Biz Babe & Haro brand manager Jill Hamilton installed Velocity 650B wheels with Neo-Moto tires on a Haro Werx Neon all mountain bike for some 650B experimentation.

Soma also plans to show a 650b prototype at Interbike next week. The 650b tire size — in between the traditional 26 inch mountain bike tire size and the 29 inches used on 29ers and typical road bikes — is liked by MTB designers because the required design changes aren’t as radical as those required for 29 inch designs.

Guitar Ted believes that the 650b trend will continue, although he says the larger bike builders will probably need to weed something out before introducing yet another tire size to the mountain bike market.

I will be at Interbike next week and promise to provide plenty of photos and news from the show.

Henry Cowell State Park mountain biking

I’m not much of a mountain biker, but the past few Sunday’s I’ve ventured into Henry Cowell Redwoods State Park in Santa Cruz County. The park’s south entrance on Graham Hill Road is just 2½ miles from my front door, so I ride my bike there. The hiking trails are off-limits to mountain bikers, but bicycles are permitted on Pipeline Road, Rincon Fire Road, Ridge Fire Road, and Powder Mill Fire Road. Although these are called “roads,” motor vehicle use is for authorized State Park vehicles only.

Towering Redwoods

Pipeline Road is a paved multi-use path shared between cyclists, walkers, and equestrians. This road runs from the park’s south entrance on Graham Hill Road in Scotts Valley to the Henry Cowell State Park visitor center near Felton. Brakes and low-gearing are handy for the steep sections at the south end of the road.

Powder Mill Fire Road is a short, wide dirt trail from Pipeline Road uphill to the park campground before ending at the Observation Deck. The observation deck is at the highest point in Henry Cowell and gives spectacular views down the San Lorenzo Valley into Santa Cruz and Monterey Bay.

Ridge Fire Road runs straight down from the observation deck to cross Pipeline Road. Ridge Fire Road between the high point and Pipeline is a steep downhill sand trap with monster water bars. I have difficulty negotiating this trail (i.e. it’s not much fun either up or down) with my inexpert mountain bike skills. Beyond Pipeline Road, Ridge Fire Road continues as a nice, smooth dirt path with some leaf litter before it circles around to connect again with Pipeline Road.

Rincon Fire Road connects with Ridge Fire Road and winds steeply downhill to the San Lorenzo River. Most of this trail is somewhat bumpy dirt, though gravelly sections, steep turns and fallen trees across the trail add interest. Rincon Fire Road crosses the San Lorenzo River — you must carry your bike and ford across the river — where it continues steeply uphill to the park’s southwest entrance on Highway 9.

While the scenery throughout Henry Cowell Redwoods State Park is spectacular, for mountain bikers the Rincon Fire Road provides the best views, with close up encounters with redwoods and stunning drop offs into the river valley. The Redwood Cathedral along Rincon Road is beautiful circular arrangement of giant old-growth redwood trees.

To return into Henry Cowell from the Rincon Road parking lot, you can bike up Highway 9 toward Felton to the visitor center entrance, where you can get back to Pipeline Road. To extend your ride, the U-Con trail runs across Santa Cruz’s Pogonip park to connect Rincon Fire Road with UCSC Mountain Bike trails and the spectacular riding in Wilder Ranch State Park along the wild and rocky California coastline.

Bikes banned from Slovak trails

Slovak President Ivan Gašparovič signed into law legislation that will ban bikes from forest trails in Slovakia.

Slovak mountain bikers were caught by surprise when they learned that a widespread ban of mountain biking on forest trails has been proposed. Just few days after the information became public the Slovak parliament passed the legislation, albeit after heated discussions. Mountain bikers believed they would be able to persuade the Slovak President to veto the law. A petition against the new regulation was signed by 3,000 people within a day of the decision and eventually garnered close to 16,000 signatures. Yet, without any advocacy organization of their own, it was hard for Slovakian mountain bikers to take further decisive steps.

Wow, two mountain biking posts in one day is more than I’ve done the whole rest of the year. Will Fritz turn more to mountain biking in the near future? My sources for mountain bike news include Go Clipless and Blue Collar Mountain Biking.

MTB: Sand riding?

I’m not an expert mountain biker, but I enjoy the occasional foray into singletrack and I know the basics of riding through sand: deflate the tires, unweight the front, and push your way through.

But what if you also need to clear 18 inch water bars? Going uphill, I didn’t have the strength to bring my bike up and over the water bars while pushing through sand. I don’t know if there’s any more technique I can bring to this so I can accept that I just have to carry the bike or muscle it through on the uphill.

But is there something I can try going downhill? I tried a few things, but the result was front wheel plant in sand downhill of the water bar, with the resulting back end flipping up and over. (Yes, I was ready for it and landed on my feet while ditching the bike).

Thoughts?
