BNS Mobile

BNS Mobile - Professional Race ServiceThe BNS wax crew hits the road in our new rig, BNS Mobile, pushing our goal of providing World Cup Service for Everyone at events across the country.  BNS Mobile travels to races offering professional race waxing services and a mini-BNS store. It serves as a base for our testing and waxing operations and is a great resource wherever you are headed.  Visit the BNS Mobile page for more information, including event schedules and the latest test results and wax recommendations.

Stone Grinding

Stone grinding flattens the ski base, removes burnt and damaged base material and provides important micro-structure.  Bottom line, it makes your skis faster and easier to wax.  We have advanced Tazzari stone grinding machines set up in our Boulder shop.  Skis can be dropped off at our Boulder, CO or Portland, Maine stores.  If you are shipping skis to us, please ship directly to our Boulder store.  Click this link to see our Stone Grinding Menu and Service Schedule/Lead Time.

Hot Box Wax Treatments

Saturate your base with wax for durability and glide.

Basic Saturation $19: Basic Saturation involves applying a very soft paraffin wax to the ski and placing it in the heat box for 90-120 minutes at a temperature of about 55 degrees Celsius (131F). This ensures excellent saturation of the base. The skis will need to be hardened with colder wax for the appropriate conditions.  This hardening can be done with 2-3 layers of ironed-in wax or hot box treatment.

Extreme Saturation $29 (Recommended): This is a two-step process with the first step being application of a very soft paraffin which is placed in the heat box at low temperature (50-55C) for a long time (6-12 hours).  The skis are scraped and a harder paraffin wax is applied followed by the heat box at 60C for approximately one hour.  This second step is still very safe for the skis, but the temperature but may hasten any inevitable movement of the base away from dead flat.  We notice that some skis, especially older models, tend to get concave tips and tails after heat boxing, even after grinding.  The same thing will happen over time and with ironing, but the heat box may accelerate the process.

This treatment will saturate the base and then harden it to a level where it can be race-waxed with high-temperature fluoros and cold waxes.

Race Ready $49: Extreme Saturation plus finish with the specified Swix race wax (LF, HF or HFBD).  The skis are saturated, hardened and then two layers of LF/HF are applied, scraped and brushed, leaving the skis ready to race or for application of Swix Cera F pure fluoro.  Cera F treatment can be added for $20.

Race Wax Services

BNS wax techs offer race waxing services out of the shop and on-site at several events each winter.  We can prepare your skis for any race, just bring them in and we'll get them ready to go.  $39 for High-Fluoro (LF & HF Layers) and $85 for pure fluoro (LF, HF + Pure Fluoro). 

Weekly Nighthawks race special: $15 for a race prep LF wax.  Drop your skis off any day by 3PM and pick them up the next day after 2.

BNS crew makes the fastest skis of the day!

Success in waxing depends mostly on picking the right racers. Today we waxed for Kris Freeman and Noah Hoffman, so our odds of success were pretty good. Our big plan for the day was: DON'T SCREW UP. We put the guys in the race and they did pretty well.

With a staff of five and only two racers we got a little bit ambitious with testing this morning. Even with good tests on Friday for paraffins and powders, we decided to retest our top four powders in the morning, as well as top coats and structures. We also spent some energy testing skis for the guys in the morning. We put LF Graphite and Matrix Blue on a total of nine pairs of skis last night. This morning we started with a basewax test, and liked the feeling of the new Vauhti K-Line basewax that Seppo from Canadian Wintersports sent me recently. It was a little faster than some of our usual basewax solutions, and all were adding some kick to the Rode Violet kick wax that we started with as our testing baseline.

Our goal was to do pretty short ballpark kick wax testing on test skis, and then focus our attention on building good wax jobs on race skis for the guys. Rode violet stayed good for us, and in spite of a few minor attempts at complicating things, we ended up with race skis feeling really close on the K-line base with three layers of Rode Violet.

That took us to about 8:30AM, with a 9:00 start. And this is when Eric Pepper got really nervous. I didn't want to powder nine pairs of skis, so we held off on putting fluoro powders on until we had the race skis nearly ready to go. So, at 8:30 we had a brief pre-race frenzy, running race skis about 1km from the stadium back to the trailer in the parking lot to put on powder and optimizer. Our morning test confirmed the powder call from yesterday, with Holmenkol Mid 02 and a Ski*Go test powder running equally well. The Ski*Go is easier to work with, so that's what I put on the race skis, mostly in consideration of the short time-line. We also put on Ski*Go C55/99 fluid which won our optimizer test. It was a toss-up between Mid 08 block which was best in the dryer snow and at lower speed, and the 55/99 fluid which was best in the glazing snow and at high speed. The call to go with 55/99 was taking into consideration the good durability of the Ski*Go liquids. Also, Kris and Noah are strong enough to keep up striding and double-poling, and we figured that the waxers would look better if they had really fast skis when they were tucking. (That last part was a joke, but Pepper was concerned that some people might not get it.)

While I was powdering and top-coating skis, Eric was chasing a few kick wax options to find a little more speed or a little more kick. The guys had both picked medium-stiff skis - coincidentally, both were the same pairs that they used at the World Champs in Oslo in the 15K. So we had a little bit of room to work with for adding wax. Eric found that a layer of Guru Hallgeir Extreme gave a little extra speed to the skis without stealing any kick. The Hallgeir is usual a wax for older snow, but we've had great luck with it in new snow - especially for finding good speed. So, we added one more layer of violet, and then a thin shell of hallgeir before sending the guys to the start.

That was about it. For tomorrow's 30K the forecast is very similar. We're going to take the skis further tonight, going with LF Graphite / Matrix Blue / Mid 02 tonight. We'll probably also put the K-line basewax on tonight as well. Our next full test will be on the training day on Monday. Eric and I are really happy to have Tom Troutner, Nate Brown and Mike Vigers here helping out. The extra hands makes it possible to do a little extra. After the race Kris mentioned that he liked the way the crew was working - that's high praise from a guy accustomed to World Cup service! So - thanks guys. Lots more 5AM mornings coming...
