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.

Bozeman Supertour Wax Recommendation 12/3/11-12/4/11

Races will take place after last minute snowfall





BNS Wax Recommendation





Bozeman Supertour Dec 3-4 2011

 

The weekend’s races are a freestyle sprint prologue followed by a skate distance race on Saturday and a classic mass start distance race on Sunday. Due to a lack of snow at Bohart Ranch, the loops are short and will have areas of shoveled snow.  New snow has fallen in the last few days including this morning adding to the variability of the conditions.  Up hills are sugary from the shoveled snow and in some spots the trail has become glazy.  There is spotty coverage on some parts of the course.

 

Weather –

From NOAA:

Friday Afternoon: Scattered snow showers. Partly sunny, with a high near 33. West northwest wind around 9 mph. Chance of precipitation is 30%. Total daytime snow accumulation of less than one inch possible.



Friday Evening: Mostly cloudy, with a low around 13. West wind between 5 and 7 mph.



Saturday: Mostly sunny, with a high near 28. West southwest wind between 5 and 10 mph.



Saturday Night: A 20 percent chance of snow showers before 11pm. Mostly cloudy, with a low around 15. West southwest wind between 8 and 10 mph.



Sunday: A 50 percent chance of snow. Mostly cloudy, with a high near 23. West northwest wind around 10 mph. New snow accumulation of around an inch possible.





Recommendation

We recommend the following:

Base Layer: Ski*Go LF Graphite

 Race Paraffin: Ski*Go HF Blue or Holmenkol Matrix Blue

Fluoro Powder: Ski*Go C105 Powder

Top Coat: TBD in the AM.  BNS Test Partner Tom Nelson will be on site to assist with recommendations.

Structure: If needed TBD in the AM. 



Testing-

BNS Test Partner Tom Nelson was at the venue testing Friday morning.  Tom tested at Bohart between 10AM and 11:30AM.  Air temp. was 28F and humidity was in the mid 50’s.  Below are his notes from his tests, all based on feel.  

 

Grinds Tested-

S1.0, S0.2, S1.3

 

- S1.0 was the fastest and most "free" on the entire course and sped up in comparison with the new snow.

- S1.3 ran second fastest and S0.2 was third.  If the snow was not as warm, the S0.2 would have run better than it did.

 

Paraffins Tested-

Ski*Go HF Green, Ski*Go HF Blue, Ski*Go HF Violet, Ski*Go HF Blue/Violet 1:1 Ratio, Holmenkol Matrix Blue, Holmenkol Matrix Green

 

- Ski*Go HF Blue and Holmenkol Matrix Blue felt very fast and it was very close between the two.

- Ski*Go HF Violet was surprisingly fast, but when the new snow came in the last 15 minutes it slowed down compared to the HF Blue waxes.

- The new snow had a high amount of moisture and it was possible to make a snow ball out of it.  Snow on the ground was aggressive and balanced moisture.

 



Powders Tested-

Ski*Go C105, Ski*Go C44, Holmenkol Mid, Holmenkol Mid 08

- Ski*Go C105 was very fast in all conditions.  Holmenkol Mid wasn't as fast at the Ski*Go C105, or Mid 08, which was very close to C105. 

- Ski*Go C44 was surprisingly fast before the new snow came in and felt equal to the C105 before the new snow.

 

CONCLUSIONARY NOTES – BNS will be testing top coats, hand structure, and kick wax at the race venue. 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 Swix and Toko for their official recommendations. If you have any questions please contact us.
