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 Mojo 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 manufacturer 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.
note: supply chain issues may result in frequent substitutions for similar parts at Ibis’ discretion.

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 29″ front wheels for Mullet builds, 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
Popular MTB Tire Pairings
Let’s break this down into a couple sections: Tread and Sidewall Pairings.
Ultimate grip, ready to chew into any descent.
Assegai front, Assegai rear
Great front grip with a bit faster rolling rear tire for acceleration / climbing.
Assegai front, Minion DHR II (or DHF) rear
Most popular of aggressive setups.
Great front grip with a fast rolling rear.
Assegai front, Aggressor rear
Not as common
Great grip, with an open, medium height rear
Assegai front, Dissector rear
Not very common, but growing in popularity. The Dissector is a bit of an acquired taste locally with its shorter lugs being good for fast acceleration. Maxxis’ Dissector features larger gaps at a similar lug height to the Aggressor. The larger gaps are beneficially in looser conditions that require tires to “funnel” more dirt.
Moderately Aggressive Setups:
Proven, balanced, popular.
Minion DHF front, Minion DHR II rear
Very popular setup.
DHF front and rear or DHR II front and rear are both viable, the DHF tends to feel like the faster combo.
Fast, fun, great for loose over hard.
Minion DHF front, Aggressor rear
Another popular setup. As dirt conditions improve over the winter this is often a go replacing a Minion rear.
Minion DHF front, Dissector rear
Not seen often as the DHF is a tall lug with tightly spaced cornering lugs while the Dissector features shorter more spaced lugs, particularly along the cornering lugs.
Dissector front, Dissector rear
For riders who need the lug spacing increased for dirt conditions but don’t need lug height.
Not seen often, although in loamy conditions this would be a fast rolling setup where riders can trust dirt to help make up for the corner lug spacing.
Fast Rolling Setups:
Aggressor front, Aggressor rear
The Aggressor is a fast rolling tire with good cornering capacity. However the relatively large transition gap may create a front tire prone to slide until the cornering lugs engage.
Rekon front, Rekon Rear
If you’re looking for fast rolling the tightly spaced and low height lugs on the Rekon are hard to beat. The Rekon as a rear tire creates interesting match up issues for the front, but if you’re riding in conditions that the Rekon is comfortable it’s a ridable XC / Trail front tire.
Minion DHF front, Rekon Rear
This is going to be a more confident setup with a more aggressive front tire providing cornering power. The Minion DHF is a slower rolling option, but, as a front tire that’s not as much of a penalty. The tightly packed cornering lugs will better compliment the Rekon than say a lower lug option like the Dissector that has greater lug spacing.

One of the most common upgrades to the 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.
