• 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 - Should I get a Hayduke or a Japhy?

• How do you ride?
  • • The Japhy is an everything trail bike - its your night ride bike, its your durable hardtail, and it can even do an overnighter once in while. The geometry is designed to be a bit more stable at high speeds, wheelie and bunnyhop easier, and lower your center of gravity by not only using a smaller front triangle and lower standover height, but a lower bottom bracket to get your feet a little closer to the ground. It also has a steeper seat tube angle than the Hayduke, making it much more enjoyable for seated climbs, and a little less forgiving on flatter, more pedaling based rides.
    • The Hayduke is a more dedicated bikepacking bike made to take more gear. It has more front triangle space, more neutral geometry for hauling a load, and more places to mount gear. It also has a more relaxed seat tube angle than the Japhy, which makes it more comfortable for flatter, more pedaling based rides.
    • If you carry gear 10% of the time, and mostly just want an awesome riding hardtail that you can depend on, get the Japhy. If you carry gear more than 50% of the time, and wanted a more dedicated bike for that purpose, get the Hayduke.

Q - How many water bottles will the Japhy Titanium carry?

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

Q - Can I put a rear rack on the Japhy Titanium?

• Sure Thing! You can utilize a rear rack by installing our Portage Rack Mount Bolts and a Seatpost Clamp with Rack Mounts.  

Q - Can I single-speed the Japhy Titanium?

• 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 Japhy Titanium?

• 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 characteristic when on the trail.
