Minimize

Boulder Nordic Sport is a full-service ski shop offering premium stone grinding, ski and waxing services at our retail locations in Boulder, CO and Portland, Maine and now at events with our traveling race service shop, BNS Mobile.  Top racers from across North America send their skis to us because we do the best quality work in the country.  Have your skis prepared by the pros and see how much better they go!

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.

Wax Testing Results, Discussion and Recommendation added. Be sure to come by our booth at the expo!!

The Noquemanon

BNS Mobile # - 303.656.3886

Well we have arrived in Marquette and wanted to lay our plans out for the week. We will be updating this post with more information as the week develops so please check back. We are excited to be here and be a part of the race and the Ski Expo. The organizers have been great to work with and reports say the course is in fantastic shape. We’re looking forward to testing wax and getting out our recommendations.


BNS Mobile will be at the Noquemanon January 26-29 with a full service team providing wax sales and brand-neutral race waxing service.  Treat yourself to a full race wax application by our pro service team so you can relax and focus on your race, or just drop by the Expo or our trailer to find out what wax is running fastest and stock up on whatever wax you need. We will be testing all brands of waxes to find the fastest solution.  BNS will post wax updates to Facebook (bouldernordic) and bouldernordic.com as well as at BNS Mobile and the Expo.

 

 

 

Testing Results and Discussion

For those of you more interested in this sort of thing I have pasted our data sheets at the bottom of this post. I will just be posting the results here to keep things a little cleaner.

 

Weather Forecast - NOAA.gov

Friday Night...Snow. Snow accumulation of 1 to 3 inches. Lows around 14. East winds 5 to 10 mph becoming northeast overnight. Chance of snow 90 percent.
Saturday...Snow showers likely. Highs around 19. Chance of snow 60 percent.

 

Thursday Testing:
We tested at two locations today. Near the start by Teal Lake and out at the Forestville Trailhead which is about 12K from the finish. At both locations we ran the speed trap for race paraffins and fluoro powders and for top coats and structure we tested by feel. We also tested a few kick waxes at Forestville.

 

Teal Lake was conducted starting at 9:30 and at Forestville at 12:00. Conditions stayed pretty consistent with the thick overcast sky, we expect today’s conditions to be representative for the race, even with the fresh snow that may fall.

 

We will be testing kick wax again on Friday morning.

Time shows time back from the winner for all except the winner.

Forestville Trail Head - Fluoro Powder - Speed Trap Results

Note: Our speed trap charge died after we had gotten through 15/24 passes. The FC7 and C105 only got 2 passes in, so the data isn't necessarily very helpful here. Given how close they are and C105's result at Teal Lake we feel really good about C105. Swix FC7 should also be a good choice.

1 Swix FC7 9.588 0.00%

Teal Lake - Topcoats - Ranked by Feel

It should be noted that all of these felt fantastic relative to the paraffins and powders and should make for a nice boost in speed in the initial kilometers.

4. Holmenkol Mid Liquid

5. SkiGo C22 Solid

Wax Recommendation - Based on testing at the venue

Base Layer:  SkiGo LF Graphite, scrape, brush

 

Race Paraffin:  Holmenkol Matrix Blue. Matrix Blue was a bit far back at Teal Lake but really shined above at Forestville.

 

Fluoro:  SkiGo C105. We feel really good about this given the testing results and the forecast.

 

Topcoat:  SkiGo C107 Fluid was clearly the best at both locations. SkiGo C105 solid would be another good option given the slightly colder temps coming. Putting a cold application of fluoro block or liquid on top of the fluoro powder layer can provide optimal speed for the early part of the race.

 

Kick Recommendations:

As always with kick it is best to test morning of rather than going off a written recommendation.


Binder: Iron in Toko Carbon Base Grip. Given the new snow be sure to
keep the binder layer very thin.


Grip: It will laregly depend on how cold it gets overnight at. At this point new snow looks certain. SkiGo HF Violet, Swix VR30/VR40/V40, Guru Green, and Rode Blue Multigrade should all be considered. SkiGo HF Violet provide very sure kick. Depending on your ability you may want to cover that for a touch more speed, cover waxes to consider are SkiGo XC Green, Guru Green, Rode Blue Multigrade, or Swix VR30 among others.

 

 

 

BNS AT THE NOQUE THE DETAILS

Ski Expo:

BNS will be on hand at the Ski Expo in the Superior Dome. We will have Holmenkol, SkiGo, Guru and other brands on hand for your viewing and purchase. Staff will be on hand for wax recommendations and to answer any questions. Additionally we will be working in the trailer outside the event if you want to stop by and check it out.


Race Service Details:

If you would like to prepay for Race Service you can purchase it HERE.

Our race service includes base prep, LF & HF paraffins and pure fluoro powder.  For classic skis, we will iron in a binder layer in the kick zone you designate, but we will not wax with the final kick wax layers. You will want to apply those race morning to achieve the best results.  We will test kick waxes, provide recommendations, and sell you kick wax if you need it, but you will have to apply it yourself race morning.

NOTE: THIS IS NON-REFUNDABLE.  BNS will refund if the race or BNS has to cancel for any reason, but otherwise this is non-refundable.

Race Service Drop Off and Pickup Details: 

Please get your skis to BNS as early as possible in order to allow us to do base prep and deliver your skis on time and without stress. Please deliver skis to us clean and scraped.  Print out your receipt and bring a copy with you to drop-off. Make sure we have labeled them with name and cell phone number.

Wednesday/Thursday Drop Off – If you would like to drop off your skis early you can drop them at the BNS trailer parked at the Super 8 in Marquette located at 1275 US 41 West. Please call the BNS mobile number to arrange a drop off time 303.656.3886

 

Friday Drop Off – The BNS trailer will be parked outside of the Superior Dome. You can drop off skis from 12-5 at the trailer. The earlier we have the skis the sooner you get them back.

 

Ski Pickup – Skis will be available for pickup at the Superior Dome Expo from from 5-10pm on Friday. Pickup time will be dependent on when you drop them off and we will give you an estimate when we receive the skis. Skis will be completed in the order they were received, so skis that enter the queue late may not be completed the evening before the race. If special circumstances arrive or you are in need of a different arrangement please contact us and we will do our best.

 

Any questions you can email mobile@bouldernordic.com or call the BNS mobile number 303.656.3886

 

Thanks!

 

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.
