Tools FAQs

Position the Chain Checker just above the chain and hold in place with one hand.

Use your free hand to push the chain up onto the Chain Checker at position 1 so that a roller is cupped by the curved protrusion.  Hold in place.

Push the chain firmly onto the Chain Checker at position 2 to create tension in the chain between between the rollers at positions 1 and 2.  Continue applying pressure on the chain upward at position 2 and release your hand from position 1.

Finally, while keeping pressure at position 2, push the chain onto the Chain Checker at position 3. If the chain is worn more than 0.75%, the protrusion at position 3 will go through the chain past the roller.  If you cannot push the protrusion through the chain at position 3, then the chain is worn less than 0.75% and is still OK to use.


The Vise Whip will work on cogs intended for 3/32″ internal width chains but not ones for 1/8″ of larger.

Before using your pump, identify the valve type.  The typical valve types are:

Presta Valve: This valve is found on many road bikes and high end bikes. It has a much narrower diameter and is generally taller than a Schrader Valve. A Presta Valve requires a small nut to be loosened. Described further below.

Schrader Valve: This is the same type found on most car tires. It is generally shorter and has a larger diameter than a Presta Valve.


Using the Pump:

1. Remove any plastic caps from the valve. For Presta Valve, make sure to unscrew the small nut at the top of the valve as shown.


2. Check the pump head and make sure the lever is centered between the two sides of the head as shown.

3. Attach head to valve:

a. For Schrader, use the black side of the head.
b. Push the head of the pump onto the valve using moderate force. If there is air in the tube the head may start releasing some air.
c. While pushing the head onto the valve, move the locking lever on the head away from the valve. The small white arrow should point at the valve.

Schrader Use

a. For Presta, use the grayside of the head. Double check that the small nut has been unscrewed and the pin can be depressed. If there is air in the tube, pressing the pin down will release air. The pin will also be pushed back up when you remove your finger.
b. Push the head of the pump onto the valve using moderate force until you reach a point where it cannot be pushed any further. If there is air in the tube the head may start releasing some air.
c. Move the locking lever on the head away from the valve. The small white arrow should point at the valve.

Presta Use

4. Pump to desired pressure.

5. To remove head from the valve, return lever to center position and carefully pull head straight off the valve.

6. For Presta Valve, after removing pump head, make sure to close the valve by turning the nut clockwise until snug.

7. Replace any plastic caps that were removed.


The Quick Link Pliers are compatible with most 5-11 speed derailleur chains with master links that use two plates like shown below.  They will also work on SRAM® Eagle 12 speed chains with Eagle™ PowerLock® chain connector.  Some single-speed chains use a different style of quick master link which cannot be removed using the Quick Link Pliers.

If surrounded with a rectangle, the Trixie is approximately 187mm long, 33mm wide, and 5mm thick. This width measurement is taken at the widest relative points at the lockring wrench end however and the width is generally much less.

All the tool bits found on the Tülio have been designed to withstand the most aggressive riding and were tested extensively on everything from professional road race stages to technical downhill trails. Scott Thigpen, an ultra-endurance mountain bike racer, seems to agree in his review. If you do ever manage to lose a bit, we’ll happily replace it free of charge.

All the tools on the Tülio are coated with a GST anti-corrosion coating rated to withstand a 500 hour salt spray test. Check out our write-up, Tülio’s Green Corrosion Protection,  to learn more.

Tire removal can be a total nightmare out on the trail. Grab your Pedro’s tire levers and head over to our Guide: How to Remove a Tire to learn more. With our bomb-proof levers and the right technique, you’ll be a tire removal pro in no time!

The Master Tool Kit includes 70 tools and a bombproof case and custom set of pallets making it perfect for travel and events. The Master Bench Tool Kit includes 121 tools, but does not include a case, and is better suited for setting up a home or shop. Check out our Pedro’s Tool Kit Comparison Chart for details.

We have spare hoses and heads for our current pump versions which were introduced in 2010. For old versions of Pedro’s pumps, we no longer carry spare parts. However, the new spare hoses and heads can be retrofitted onto older pumps.   The retrofit involves removing a fitting from the base end of you old hose and installing it into the new hose.  See image below of fitting from older Domestique and Prestige pumps.  Please contact us if you are unsure of which version of pump you have.

Fitting and retention cap from older Domestique and Prestige pumps:

We strongly recommend wrench owners work with a professional calibration service to ensure the proper equipment and techniques are employed. We have had good luck with ESSCO Lab located in Massachusetts but any similar calibration service should be able to provide calibration.

When used properly, the Vise Whip does not cause any damage to the cassette. Despite the use of the same mechanism found in vise grip pliers, the Vise Whip differs in its function and does not need to clamp down on the cog to work properly. Most people adjust the Vise Whip so that it just barely clamps to the size of the cog. However, even adjusting so the Vise Whip is a little loose when clamped will work as well.

The increase in Torx style hardware is likely based on the advantages Torx style hardware provide over hex style. The Torx design was introduced in the 1960s as a replacement to Phillips or slot style screws/driver combinations. Where the Phillips/Slot style screws were designed to prevent over tightening allowing the tool to slip beyond a specific torque, the Torx was designed to prevent slipping and reduce damage to the tool. In terms of usage on bicycles, the Torx style fastener was slow to be adapted due to the higher cost when compared to hex style hardware. As cost has come down, many designers have started to switch to Torx because of a few key advantages. First, by design, Torx are less likely to strip out when compared to a hex because of the way the load is distributed and applied between the tool and the hardware. Second, due to the this improved load handling, the height of the screw head can be reduced. This provides flexibility to product designers who are always looking for more space. This is largely the reason that the Torx bolt was first seen on bicycles in disc brake applications where a low profile was important. An added bonus, the shorter head also offers slight reduction in mass which is also helpful in bicycle applications where vehicle mass is so critical to performance.

The Cog wrench will work on any cassette that has an 11 tooth or 12 tooth cog for the high gear. These are the most common sizes but some cassettes use a 13 tooth high gear and more recently a few 10 tooth high gear cassettes have been introduced. The Cog Wrench will not work for these cassettes. Please check out the Vise Whip for these cassettes.

The Pedro’s BB Socket Holder is designed to work with the follow bottom bracket spindles:

-Bottom brackets which have an M8 internal spindle thread.  Most square taper bottom brackets have this size internal thread.

-Bottom brackets which have an M15 internal thread.  This includes the more common ISIS Standard bottom brackets with M15 spindle thread and any other spindle with M15 internal thread.

The new BB Socket Holder II, introduced Spring 2018, will fit the above bottom bracket spindles and adds the following:

-Bottom brackets which have an M12 internal thread.  This includes less common ISIS Standard bottom brackets with M12 spindle thread and any other spindle with M12 internal thread.

If you are unsure if the tool will fit your bottom bracket, please contact us with information about your bottom bracket and/or crankset.

The ICM is approximately 3.4″ long, 2″ wide, and 1″ thick (measured at the thickest part).

Overall, with the L Wrench in place, the 6-Pack Chain Tool is approximately 2.75″ tall, 1.7″ wide, and 0.5″ thick.

The Portable Work Bench features a strong and stable steel frame.  Total weight is approximately 30 pounds.

The Chain Keeper was not designed to work with 142×12. However, we have tested it on an Ibis Mojo HDR, which uses a 142×12 rear axle setup (Maxle standard), and found that the Chain Keeper will works if installed backwards (QR lever inside the frame).  This requires that the skewer be partially dissembled so the axle can be passed through the dropout but works quite well considering it wasn’t designed specifically for use in a 12×142 dropout.  We also found it easier to pull the chain onto the Chain Keeper after the Chain Keeper is installed (instead of during installation).  Check out the photos below.

The outer dimensions for the Master Tool Case are L19.8” x W16.0” x H7.6”.  The portion of the bottom half of the case not populated by pallets, provides approximately L17″ x W12″ x H4″ of empty foam-lined space.  The weight is 13lbs-2oz.

Pedro’s Cable Cutter is designed for cutting steel cables (wire rope) up to 4mm in diameter.

Chains wear out over time and become elongated.  This can lead to poor performance and even damage other parts.  Though many refer to this wear as chain stretch, none of the parts are actually being stretched over time.  Instead, chain wear is solely based on an increase in pin to pin distance.  This is caused only by wear to the chain pins and mating holes on the inner links.  Normal wear that may occur to the chain rollers does not contribute to overall chain wear, but in order to accurately measure the increase in pin to pin distance, the play in the rollers must be accounted for.  The three point measurement system used on the Chain Checker Plus accomplishes this by pushing both rollers in the same direction during measurement, instead of in opposite directions, as is the case with common two-point measurement tools.  As a result, the Chain Checker Plus achieves a true measure of the pin to pin distance.
