HD4 Features:

The Ibis HD4 frame is unquestionably on Enduro riders’ short list for review. In brief the HD4 is low, slack and fast. Cutting edge geometry, improved lateral stiffness and paired to the latest version of Dave Weagle’s DW suspension the HD4 highlights Ibis’ commitment to progression.

Due to these updates the Ibis HD4 has an incredibly balanced on trail personality. Riders will notice the HD4’s efficiency – this bike accelerates quickly and holds speed well. Once at the top of the climb HD4 riders will be blown away when they point the bike downhill. Effective front and rear balance produce a bike that’s comfortable to ride centered on the bike, easily controlling both ends of the bike in a variety of terrain. Rear shock options ensure maximum tuneability for your specific riding style. On one hand you have the DPX2, a shock which appeals to the trail oriented rider and on the other the X2 with the best damping controls on the market for aggressive Enduro rips.

Either 160mm or 170mm forks may be run on the HD4, however our experience indicates the 160mm option provides the widest range of application up and downhill. The 170mm option provides more travel and a slightly slacker geometry for the biggest terrain or park type riding but may wander a bit climbing. However if you prefer the 170mm option feel free to reach out to our sales staff and they will dial you in.

BikeCo Frame Prep

All frame, frame kit as well as complete purchases receive a thorough BikeCo Frame Prep.  Riding a bike without appropriate bearing retention, torque and alignment is hard on components. As a result “loose” bikes not only make noise but will also wear prematurely. BikeCo’s expert mechanics go through each chassis ensuring that suspension, bearings, and hardware are setup for maximum performance as well as longevity. Many home builders have a full frame assembly completed by BikeCo mechanics to ensure the best setup, in brief headsets, bottom brackets, suspension, derailleur hangers, etc are gone through piece by piece.

Maximize your suspension’s performance with BikeCo Pro Tunes

BikeCo offers proprietary Pro Tune services on the majority of Fox forks and rear shocks.

Fox Suspension is the pinnacle of performance, reliability, and longevity in our industry. Stock Fox suspension comes out of the box with a fairly aggressive tune – which is terrific for powerful, strong, aggressive riders with high ground speeds. Sounds like their World Cup DH and Enduro riders, right?

Pro Tune services calibrate the incredible performance of Fox suspension into a narrower band personalized to your riding specifics.

Utilizing a combination of proprietary lube oils, improved upper to lower fork fit, shim stack configuration, updated oil flow, unmatched bleed quality, and a few other trade secrets BikeCo Pro Tunes improve tracking, small bump compliance, minimize brake dive, run cooler (equating to more predictable performance from top to bottom of your descent), operates comfortably in a wide range of temperature (we test from freezing to 100 degrees), improves oil circulation, extends service intervals and more.

The most important advantage of Pro Tune suspension? Whether you are new to the sport or an experienced pro: suspension that works will let you ride more confidently. You will ride faster and have more fun with BikeCo Pro Tune Suspension.

To ensure that your suspension is dialed in our staff will review your riding experience, aspirations, ground speeds, size (height and weight) as well as specific chassis. BikeCo stands behind our Pro Tune service with a 30 day retune service if you feel that your particular riding requires a shift in tuning. BikeCo also offers discounted disposition retunes as your skillset progress if required.

After the Pro Tune your suspension only requires standard levels of maintenance in the future. To maintain the best performance BikeCo recommends sending the suspension in (we use proprietary lube oils, have specific bleed techniques, etc) although standard Fox oils can be used. Standard lubes will compromise some of the finite tune but with the other Pro Tune modifications a standard lube shock will still out perform stock.
