Japhy FAQ
- Looking for a review?
- Check out this recent review from Bikepacking.com - CLICK HERE
- Q - What size frame should I buy?
Q - What wheel sizes can I use on the Japhy?
- The Japhy was designed and optimized for 29" wheels (up to a 2.8" width).
Q - Whats the maximum tire width that the Japhy will take?
Q - What fork travel can I use on the Japhy?
Q - Can I run a rigid fork on the Japhy?
- Absolutely! Rigid works with an axle to crown measurement of ~492mm work best to maintain the original geometry design and ride characteristics.
Q - How many water bottles will the Japhy carry?
- SM = 1 bottle in the front traingle, 1 bottle under the down tube
- MD/LG/XL/XXL = 2 bottles in the front traingle, 1 bottle under the down tube
Q - What length dropper comes with a complete build?
- SM = 150mm PNW Loam dropper that can be adjusted down to 120mm of travel, or a 160mm Wolf Tooth Dropper that can be adjusted down to 110mm of travel.
- MD/LG/XL/XXL = 170mm PNW Loam dropper that can be adjusted down to 145mm of travel, or a 200mm Wolf Tooth Dropper that can be adjusted down to 150mm of travel.
Q - Can I put a rear rack on the Japhy?
- Sure Thing! While our Hayduke model has dedicated rack mounts built into the frame, the Japhy can still 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?
- 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?
- Technically, yes, but we don't offer any support on figuring out which hubs and support parts may be needed in order to make this happen. Have fun!
Q - Can I run a Belt-Drive on the Japhy?
- No you cannot, chains only for Esker hardtails.
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 - The Size/Color that I want is out of stock, is there anyway to get the specific one I want?
- Possibly. Shoot us an email at info@eskercycles.com and we'll do our best to connect you with one of our retail partners if they have one in stock.
Q - How long does it take to get my bike/frame once I order it?
- That depends. If its a bike/frame that you're placing a Pre Order for, the item will have an ETA window associated with it once you select it on the product page. If its a bike/frame that we have in stock, we will email you the shipping eta once the order is placed - that can vary from 2-6 weeks depending on how many orders are in front of yours.
- NOTE: If you want to speed up the delivery of your frame/fork, order it through one of our Retail Partners. They receive priority shipping when orders are placed through them.
Q - How much assembly do I need to do if I order a bike directly through the webstore?
- Not much at all. Our complete bikes arrive 90% pre-assembled. For more information and assembly instructions, head on over to our Tech Documents page and click the 'New Bike Assembly Instructions' link.
- If you would prefer having your bike assembled through your local Esker Retailer, please order your bike directly through them. They'll help you figure out your size, work with you on spec/upgrade options, and get your bike built for you exactly how you want it.
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 - What kind of steel do you use?
- Our steel frames utilize an in-house designed proprietary 4130 chromoly tubeset. This custom drawn, externally tapered, seamless tubeset is quadruple butted to ensure the best combination of weight savings, torsional rigidity, and overall strength. We heat treat all of our steel frames and finish them off with an electrophoretic deposition (ED) coating inside and out prior to paint. This ED coating helps to protect the frame from rust and corrosion (no frame saver needed!)
Q - What kind of Titanium do you use?
- We build our titanium frames from seamless, double-butted 3/2.5 titanium. This tubeset provides an incredible balance of weight and strength that we find to be paramount for those big backcountry missions and covering the countless miles of abuse we've seen on our frames. We engineer this tubing specifically for this application and value Titanium's longevity both in fatigue, abrasion and corrosion resistance.
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.
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?
- Esker 1,000,000 Mile Warranty: Yup, you read that right, we'll cover any defects in material, craftsmanship, or design up to 1,000,000 miles. If you hit 1,000,001 miles...you're on you own, and CONGRATULATIONS :)
- Esker Cycles will repair or replace, at its option, any frame that it determines to be defective due to defects in the original materials and/or manufacturing. This limited warranty does not apply to wear and tear, prior claimed defects, or any failures or malfunctions that result from abuse, neglect, misuse, alteration, crash, collision, or any improper assembly or maintenance.

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?
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 - I want to buy a frame bag before my bike/frame arrives to me, can you provide the frame bag dimensions for the Japhy?
- We don't reccommend 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 Japhy, 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 the following frame bag makers to get the exact bags made for your bike that you want!
- Cadaero - Two Harbors, Minnesota
- JPaks LLC - Denver, Colorado
- Rogue Panda - Flagstaff, Arizona
- Rockgeist - Ashville, North Carolina
Built for the Back Country
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 tenets:
Durability
We build our titanium hardtails from seamless, double-butted 3/2.5 Titanium for the utmost in durability.
This tubeset provides a greater strength to weight ratio than other Titanium frames on the market, engineered specifically for its application. Titanium is corrosion-proof, so you can ride through any weather, for life.
Geometry
With 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
Ride Quality
Titanium is legendary for an almost mystically smooth, fatigue-reducing ride quality. The custom drawn, seamless, and butted tubeset is tuned to each size, which gives it more compliance and is lighter weight while also increasing torsional rigidity and overall strength.
