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.

Updated with Test Results and Final Recommendation
Test results and Final Recommendation For Saturday's Race

Seeley Classic
22k and 42k
January 14, 2012

 Event Description – The Seeley Classic is a classic only race held on the Birkie Trail out of the “OO” Trail Head.  The shorter distance event is an out and back heading South from the Trail Head on the Skate Trail.  The longer marathon distance heads North on the Classic Trail to the Fire Tower Food Station and then U turns back to “OO” on the Skate Trail.  It then joins and follows the course of the shorter event.  As far as terrain, it’s the Birkie Trail.  Start,up, down, up, down, etc( repeat about 100 times)… finish.

Event Groooming:  The final grooming will take place after dark on Friday.  It will be done before midnight and have 10 hours of time to set.  The tracks will be predominantly firm new snow with very little abrasive old snow or ice.  The track set should be very firm as the temps are going into single digits Friday night.  The course should be very good for a classic race!

Weather http://forecast.weather.gov/MapClick.php?map.x=224&map.y=211&site=dlh&zmx=1&zmy=1

Test Based/Forecast Based Recommendation:  The testing was done on Friday the 12th at 2PM.  The snow temp was 11F and air temp was 13-16F.  New light snow had fallen and the conditions and temps are what is forecast for race time tomorrow.

Testing Discussion:  6 different race parrafins were tested with 4 pairs of matched test skis.  The test was a feel test both in and out of the tracks.   3 different powders were tested using matched skate test skis and  these were feel tested for speed and climbing.

TEST RESULTS

Kick

1.Holmenkol Blue (Best kick, least drag)

2. Guru Blue (Similar to 1, just a slight more drag)

3. Swix VR40 (Good kick, just a little too draggy)

4. Rode Blue (Draggy)

Note:  Most Blue waxes kicked just fine.  If a wax choice is too slick, then any of the draggy waxes applied under the toe box will help to enhance the kick.  Start short and lengthen and thicken, before going warmer.  The test skis had a layer of Toko Green Binder heated into the ski and 3 layers of test wax corked in.  In ski prep for the event sand your kick zones and apply two layers of Toko Green Binder  with heat before applying the final layers of kick.  I recommend 3-5 layers of race kick wax depending on the event length.

Race Glide

  1. Holmenkol Matrix Green
  2. Toko HF Blue
  3. Holmenkol Matrix Blue
  4. Holmenkol  Matrix Blue/Red 50/50 mix
  5. Holmenkol Speed Base Mid
  6. SkiGo HF Blue

Race Flouro Powders

  1. Holmenkol Cold
  2. SkiGo C105
  3. Toko Jet Stream Blue

Recommendation

We recommend the following:

Base Layer: SkiGo LF Graphite iron, scrape brush.

Race Paraffin: Holmenkol Matrix Green or SkiGo C380

Fluoro Powder:  Holmenkol Cold.

Top Coat:  Will test on Saturday morning.

Structure:  Fine linear.  0.2mm recommended.

CONCLUSIONARY NOTES – BNS will have a table set up by the grooming building adjacent to the warming building and will be testing top coats and kick wax at the race venue Saturday morning. Come by to get our latest test results and recommendations.

Note: BNS imports Holmenkol and SkiGo waxes, and also sells waxes from Swix, Toko, Rode, Solda, Rex, Guru, Innovax, Magnar and others. We search for the fastest waxes for our customers and our testing is professional, objective and transparent. We make our best effort to test what we think is the best from each brand.  However, given that we are testing more options from Holmenkol and SkiGo, there is a bias toward those brands.  With this full disclosure, you can assess the legitimacy of our testing yourself. Visit http://swixracing.us/nordic/waxrec.php and http://tokous.com/racewaxtips.htm for their official recommendations. If you have any questions please contact us.

 

Wax Recommendations

The are two types of wax recommendations: testing-based and forecast-based. It is important to distinguish the difference between the two so you know when you can trust them explicitly or when you might want to verify the suggestions with your own testing.

TESTING-BASED RECOMMENDATIONS

Testing-based recommendation are made by putting skis on snow in conditions that best represent race conditions and comparing waxes or other variables directly. This is done using a speed trap and/or by ranking the skis by how they feel on the snow. This type of recommendation is the most reliable as it is supported by data gathered in race conditions. As long as the tester does a professional job using matched test skis, you can generally trust this type of recommendation and follow these suggestions with confidence.

FORECAST-BASED RECOMMENDATIONS

Forecast-based recommendations are made by analyzing current snow conditions and the weather forecast without actual on-site testing. While this type of recommendation is useful, there is more room for error and the quality of the recommendation depends more on the experience and knowledge of the person making the recommendation. Fortunately, there is a lot of easily accessible weather information out there nowadays and an experienced wax tech can make a highly educated guess. But you should be aware of the qualifications of the person making the recommendations and what they base their assumptions. It is always smart to back up this type of recommendation with your own on-site testing and one or two alternatives in case the prediction is way off.
