Ibis Mojo 4 Mullet Builds
BikeCo.com offers several upgrade options for the Ibis Mojo 4. One of the most popular is the Mojo 4 Mullet Build.
Mullet bikes feature a 29″ front wheel in place of the stock 27.5″. The larger wheel provides several positive personality shifts for the Mojo 4.
With a longer tire contact patch the 29″ wheel provides notably improved braking. The larger diameter combo also helps mellow steering input adding confidence in high consequence corners.
Riders aggressively attacking steep trails will find the smaller 27.5″ rear wheel changes direction quicker than a 29/29 bike. The smaller diameter also means less, ah, tire to shorts contact when you put the bike in the air…
There are a pair of popular travel concepts when you mullet a bike and both involve using a lower travel fork than the stock 27.5″.
Since the 29″ wheel produces a level of “false suspension” with improved roll over angles the choice becomes how much of a travel reduction your riding style will benefit from.
At BikeCo we’ve been working with 29″ forks that don’t shift a mullet bike’s axle to crown very much. This keeps the geometry closer to the standard design and keeps a bike’s personality closer to the manufacturer’s design.

RockShox Pike Ultimate RC2
Ibis Mojo 4 Fork Travel Options
140mm Ibis Mojo 4
The Mojo 4 is spec’d with a 140mm RockShox Pike Ultimate RC2. This provides the bike with it’s stock 65.4 degree headtube angle and 340mm bottom bracket height.
Riders looking for a little more aggressive setup may investigate the 150mm option.
150mm Ibis Mojo 4
Perhaps more than the additional 7% of travel the 10mm adds are the geometry modifications. Raising the front of the Mojo 4 will slacken the headtube, increase the trail measurement and slightly lift the bottom bracket.
Riders looking at adding to the Mojo 4’s capacity should chat with our team about 29″ Mullet options as discussed above as well!
These are popular shifts for riders pushing the Mojo 4 into bigger trails, attacking the steepest, burliest terrain.

Air Spring & Volume Spacers
The RockShox Pike Ultimate RC2 provides riders a range of setup options using air spring as well as volume spacers.
Suggested sag is 15% for a firm feel and 20% for a plush fork. On the stock 140mm setup 15% equals 21mm or about 0.8 inch of sag. 20% will use 28mm. The Pike has sag indications printed onto the fork uppers for quick sag adjustment.
Volume Spacers / Bottomless Tokens
Adding volume spacers, or bottomless tokens, will increase ramp rate providing more support in the suspension’s mid stroke as well as providing more bottom out resistance.
Removing volume spacers will lower support and bottom out resistance creating a more linear fork feel.
Do not install more volume spacers than the FOX advises. Installing more than the maximum volume spacers will result in product damage and potential for injuries, etc.
RockShox Pike Rebound Controls
The RockShox Pike Ultimate RC2 provides rebound adjustment located at the bottom of the fork lower.
Rebound settings vary depending on rider weight and aggression. Dialing in rebound is important to produce the best ride quality on your bike. Since rebound controls the air spring’s return to a neutral or loaded position the higher PSI in the air spring generally the more rebound setting will be used to control that energy on return.
RockShox Pike Ultimate RC2 Compression Controls
The RockShox Pike Ultimate RC2 provides Low and High speed compression controls to fine tune support.
Compression circuits hydraulically damp (or slow) the fork’s input assisting the air spring in providing appropriate mid-stroke and bottom out feel.
Low Speed Compression helps provide mid-stroke support. This allows a bike to ride taller in the travel in cornering while resisting brake dive, rider weight shift and other slow shaft speed inputs.
High Speed Compression works to fine tune bottom out feel as well as other high shaft speed inputs also known as square edge bumps. Example: if you sprint straight into a curb you’re likely to engage the High Speed Compression even if you’re not using full travel. This is due to the speed of the shaft moving oil to compensate for the hit.
FOX Float Factory DPS
Air Spring & Volume Spacers
The Ibis Ripley uses a 210 x 50mm shock, spec’d with the Fox Float Factory DPS.
SAG is adjusted by PSI – typically trail riding styles gravitate to 25-30% sag. This would measure about 12.5mm for a plush setup and 15mm for a more firm setup.
Volume spacing provides fine tuning options to support the air spring.
By changing to a larger volume spacer, thus reducing the volume, you increase the air spring’s ramp rate for improved bottom out support and pop.
Conversely smaller volume spacers produces a more linear feel as the air has more volume during shock compression per mm of travel.
Do not install more or larger volume spacers than the RockShox advises. Installing more than the maximum volume spacers will result in product damage and potential for injuries, etc.
FOX FLOAT FACTORY DPS Rebound Controls
The DPS provides a rebound control with 11 clicks of adjustment.
Heavier riders will use more rebound control than lighter riders to slow the air spring’s return to neutral.
As your ground speeds increase it is common to allow your bike to rebound more quickly to prepare for the next terrain feature and avoid suspension packing from slow rebound setup.
FOX Float Factory DPS Compression Controls
The Fox Float Factory DPS shock provides two controls to help fine tune compression.
First is the blue 3 position switch which adjusts from Firm, Mid and Open. Also known as a “climb switch” the use of this is dependent on rider style, preference and terrain.
Fine tuning the low speed compression can be accomplished in the Open mode by adjusting the black dial located around the circumference of the blue 3 position switch.
3 settings are available with “1” being the most plus and “3” the most firm.

Popular Upgrades to the Ibis Mojo 4 Complete
There are a variety of popular upgrades or part swaps on the Ibis complete bikes. Flip through the tabs below to explore some of the most popular including Brakes, Tires, Chain Guides and Frame Protection.
Along with tires the most common upgrade or swap to a stock Ibis build is brakes.
Brakes are extremely important to your bike’s personality as well as your confidence on trail.
Finding brakes with the right modulation and power for your riding style allows you to further fine tune performance with rotor size.
Brake modulation is how the lever position relates to the amount of power at the caliper.
Brands like Magura and Hope offer great modulation. A slight pull on the lever will produce less pressure at the caliper and increases as lever throw continues. Magura riders can fine tune this even further with a variety of short or long brake levers to further modify the leverage ratio. In fact, Magura offers brake levers with adjustable modulation!
Shimano brakes have less modulation and the power tends to “come on” quicker. This isn’t necessarily good or bad – it’s just a personality.
Magura and Shimano offer similar levels of total power differing in personality more on modulation than max power or feel.
Hope brakes have a little less “bite” at full power but most riders are able to fine tune this by running a slightly larger rotor to increase both leverage and heat capacity.
Pricing / Value
Interested in updating the brakes but on a tight budget? Check out the Magura MT5. In many cases it’s available as a No-Cost upgrade. Cost conscious yes, light on performance or service life? Not a chance. The MT5 brake is the most popular offering here at BikeCo.com
Mojo 4 Tire Upgrades / Swaps
The Ibis Mojo 4 kits are spec’d with Hans Dampf 2.6″ front tire and Nobby Nic 2.6″ rear tires. These are on the very aggressive and high volume end of the spectrum providing a lot of grip through contact patch – but tend to be a bit slow rolling in many conditions.
Since tires play such a big role in a bike’s personality it’s very common for clients to swap to other tread patterns, sidewalls or sizes.
Some of the most popular changes are listed below.
Front Tire: Spec’d Hans Dampf 2.6″
The 2.6″ Hans Dampf is a great tire for riders looking for the maximum contact patch, large tread spacing and relatively deep lugs. The downside to the 2.6″ Hans Dampf is it tends to be slower rolling and compromises some of the crispness that Mojo 4 riders are craving.
Narrower, more tightly packed tread options will decrease rolling resistance providing a more poppy, agile setup. Popular front tires for the Mojo 4 are listed below.
Riders looking for a bit faster rolling front tire typically review the Maxxis DHR II and DHF.
While the DHR II is branded as a rear tire it is popular as a front tire in some conditions. This is due to the slightly larger spacing and braking sipes in the tires center section.
The Maxxis DHF is probably the most popular front tire across MTB. Designed with tall cornering knobs and moderate center section the DHF is designed to roll fast and corner hard.
Mojo 4 riders may decide to go faster than the DHF balancing the decreased weight and grip levels to their terrain. The Aggressor is shown, but tends to be a better rear tire as the large spacing on the cornering lugs can lead to slide during direction changes.
The “fast” end of the tire spectrum would be the Ardent and Rekon front tire options for the Mojo 4 – but these truly “fast” tires tend to be preferred in 29″ format over 27.5″, as the smaller tires can become a bit too, ah, lively at speed.
Rear Tire: Nobby Nic 2.6″
Ibis spec’s the Nobby Nic 2.6″ rear tire paired with the 2.6″ Hans Dampf front giving the Mojo 4 plenty of contact patch grip for increased traction and confidence. However, most Mojo 4 riders are looking for something that’s a bit faster rolling and poppy.
Riders looking for faster rolling rear tire options tend to shop the Maxxis DHR II, then the DHF (slightly tighter packed and faster than the DHR II), followed by the Aggressor.
The Aggressor paired with the DHF is probably the most popular pleasure riding tire combo for the Ibis Mojo 4. It provides enough bite in the burly terrain without having bike park level tires on your all day pedal adventures.
Looking to go even faster on the rear tire? Chat with us about the new Rekon tire’s with aggressive sidewall technologies for support.
Upgrading your Mojo 4 to Maxxis tires? Along with tire width, tread pattern and compound Maxxis offers a variety of sidewall protection levels.
The proper sidewall provides support allowing riders lower air pressures for better grip as well as resistance to damage on trail.
Below are the levels of additional sidewall protection and support available from Maxxis.
An extremely cut-resistant and abrasion-resistant material added to the sidewalls of select mountain tires. This densely woven fabric is also lightweight and highly flexible, ensuring that the performance of the tire remains unaffected. Choose EXO Protection for exceptionally rocky, treacherous trails where the chance of sidewall cuts and abrasions is high.
EXO+ construction combines two puncture protection materials: SilkShield and EXO. The SilkShield layer runs from bead-to-bead with a layer of EXO along the sidewalls. Combined, these two materials create EXO+ which improves tread puncture protection by 27%; sidewall durability by 51%; and resistance to pinch flats by 28%.
Riders looking for additional sidewall support and resistance to damage will shop the Double Down or DD options
DoubleDown (DD) is the next step in the evolution of the dual-ply tire casing for enduro racing. Two 120 TPI casing layers reinforced with a butyl insert provide the enduro racer with the support and protection of a downhill tire, but in a lighter package.
The “light” tire option for most enduro riders would be the EXO sidewall.
One of the most common upgrades to the Ibis Ripmo is adding a chain guide.
A variety of options are available depending on your riding needs.
The Wolf Tooth Gnarwolf is a great upper guide as is the OneUp option.
OneUp goes a step further with the Guide + Bash or, for riders who don’t need or want the upper guide, simply a lower bash to protect the chain ring and bottom bracket area.
The lower bash only is a popular option with oval chain ring setups that can be complex to pair with upper guides.
RideWrap Frame Protection
A popular upgrade for any mountain bike, we offer two options of RideWrap Frame protection.
The RideWrap Tailored Kit covers the majority of your frame based on individual model size and shape. This is a $95.00 addition. We will install the Tailored kit for an additional $250.00 labor at time of initial build.
RideWrap’s Covered Kit protects the high wear areas such as downtube, top tube, etc. Custom trimming of the stock Covered Kit helps with fitment depending on model and size. The Covered Kit is $65.00 and installation is $150.00 at time of build.
Installing RideWrap isn’t particularly hard – but it is time consuming. Thinking about doing the labor yourself? Awesome! Check out a quick video on the installation process below.
