SPARKY FAQ

 

  • Q - What size frame should I buy? See the table below for a complete Esker Cycles model line-up size guide
    • NOTE: Many folks can fit more than a single frame size. If you find yourself at a height in which you can fit 2 different frame sizes, ask yourself what your riding style is like and where/how you intend to use the bike. A larger frame will feel more stable at high speeds, but not as maneuverable in tighter and more technical situations on the trail. Inversely, a smaller frame will be less stable at speeds, but allow you to pick up and place your wheels in technical sections of trail much easier.

Q - How many water bottles will the Sparky carry?

  • SM = 1 bottle in the front traingle, 1 bottle under the down tube
  • MD/LG/XL = 2 bottles in the front traingle, 1 bottle under the down tube

Q - Can I put a rear rack on the Sparky?

Q - Can I single-speed the Sparky?

  • You betcha! Our Portage Dropout System allows you to adjust the chainstay length by up to 14mm, allowing you to run a single speed setup reliably, quietly, and with ease. Heck, we even have a single speed build option that you can buy!

Q - Can I run an internally geared hub on the Sparky?

  • Technically, yes, but we recommend working with your favorite professional mechanic to figure out which hubs and support parts may be needed. Have fun!

Q - How does the Portage Dropout System work?

  • The Portage Dropout System attaches to our hardtail frames and allows you to adjust chainstay length (for ride characteristics or tire width clearances), chain tension (for single speed application), or different hanger types (UDH or Classic).

Q - Do you do custom builds?

  • We do not. We offer a limited menu of upgrade options for all of our bikes, but we do not do custom builds.
  • If you'd like to have a custom Esker built up, please reach out to one of our Retail Partners and they'll work with you on getting you exactly what you want!

Q - Do your steel frames ride different than your Titanium frames?

  • Yes and No. Based on our own riding input, as well as a ton of great input and feedback from our customers, find that our steel frames have a very similar feel when it comes to compliance on the trail in comparison with our Titanium frames. The biggest difference that most individuals feel is the weight savings of Titanium. Our Titanium frames are around 650-900grams lighter than their steel counterparts. This weight savings results in a 'snappier' and more 'lively' riding characteristics when on the trail.

Q - Do I need to 'Frame-Saver' your steel frames after I buy one?

  • NOPE! We treat all of our steel frames with an Electrophoretic Deposition (ED) coating inside and out prior to painting them for rust protection.

Q - What does your warranty look like?

Q - Can I order one of your frames/bikes through a local bike shop?

  • Absolutely. That would be the best way to order one of our frames/bikes! Working with your local bike shop allows you to get great insight on which model is right for you, which size may work best for your intended use, and ensure that your bike gets built up and fit to your exact specifications. Jump on over to our Dealer Locator to see a full map of our retail partners and find the one closest to you.

Q - Can I demo a bike before I buy it?

  • We do our best to travel around throughout the year and often partner with regional mountain bike festivals or local retail partners to host demos. For the most up to date opportunities, check our Dealer Locator.  You can also see a full map of our retail partners - reach out to them if you're near by and ask them what they may have available for you to demo locally.
  • Q - I want to buy a frame bag before my bike/frame arrives to me, can you provide the frame bag dimensions?

    • We don't recommend buying a frame bag until you have your frame/bike on hand. That is absolute best way to ensure you get the right size and shape for your bike.
    • If you're looking to make a custom bag(s) for your Esker, we've partnered with some incredible custom frame bag makers that all have our frame dimensions and files on hand. Please reach out to one of them HERE.

 

BUILT FOR THE BACKCOUNTRY

We here at Esker enjoy long rides into the wild spaces and are proud to say our bikes are truly Built for the Backcountry. That means they are designed and built on three values:

REFINED GEOMETRY:

Specific geometry to suit the riders needs for each different model, we have designed and developed a quick and responsive ride quality for all Esker models.
 
Our geometries are refined, stable, and comfortable to provide a bike that always feels right at home.

DURABILITY:

We build our bicycles with the highest quality metal tubing for the utmost in durability.

Each tubeset provides a greater strength to weight ratio than other frames on the market and engineered specifically for its application. Every Esker frame is tested to our own internal standard far exceeding ISO 4210, for a true lifetime of constant use.

Esker will get you into the backcountry as far as you want to go, but it will also get you back!

 

RIDE QUALITY:

Not too flexy, not too stiff…but just right! We are riders, and design our bikes by riding them, constantly, to refine the perfect feel.

We toil over every model to ensure the ride simply feels right and comfortable, like your favorite hoody.
