Frequently asked Questions
How do Pinion transmissions work?
The operating principle of Pinion transmissions is described at here using the example of the P1.18 transmission.
What is the deployment of the individual transmissions?
The term "deployment" refers to the distance covered per revolution of the crank. The deployment depends on the following factors: 1. Selected gear 2. Secondary ratio (chain or belt drive) 3. Wheel size You can find the deployment for your bicycle with the ratio calculator, which is available from Pinion for every model of transmission.
What is the efficiency of a Pinion transmission?
The efficiency depends greatly on the load situation (input torque/speed), which in practice varies greatly during riding and therefore a single number for efficiency cannot be calculated. In contrast to hub gears with the usual up to three planetary gears shift in succession, Pinion only has two constant gear stages. And of course the chain or the toothed belt from the transmission to the rear wheel must also be considered. With Pinion they are always straight and there is also no loss of efficiency, which occurs with the use of a rear derailleur with a skewed chain. Thus the efficiency of a Pinion transmission is between a high-quality hub transmission and a new chain shifter running absolutely straight from front to back. If a chain shifter is dirty and skewed, the efficiency of Pinion is better.
What has become of the E-Pinion?
Pinion had presented an E1.8 as a design concept at Eurobike 2011. However, a commercial product has not yet been developed from this study.
Are Pinion transmissions approved for downhill or freeride applications?
So long as the max. approved input torque of 250Nm and the rider weight of 110kg including rucksack are not exceeded, the transmission is basically approved for any application. However, please note that load peaks incurred by situations such as becoming suspended by the pedal on an obstacle or as a result of a fall may exceed the max. input torque in some circumstances and may damage the transmission. A transmission damaged in this way can be repaired at the Pinion factory but will not be covered by the warranty. The same applies for damage caused by dents in the transmission housing caused by impacts.
Who does the repair if a transmission is damaged?
If a transmission is damaged and requires repairs, we request that you first contact the dealer or manufacturer (direct sales) where you purchased your bicycle. After assessment of the damage, the dealer or manufacturer will contact Pinion and discuss how to proceed with the Pinion service technicians. A transmission must be demounted from the bicycle frame and sent to Pinion for repair (securely packed in a protected shipping package)
How long does it take to repair a transmission?
Expect a processing time of one to two weeks to repair a transmission.
Why is a chain tensioner required with a Pinion transmission?
Pinion originally developed the chain tensioner for full-suspension frames to compensate for the chain extension during compression of the rear suspension. However, it can also be used with a rigid frame that does not have an integrated chain tensioning function (such as adjustable dropouts).
Why is the chain tensioner fixed to the transmission and not the dropout with Pinion?
Pinion considers that the position on the dropout is exposed and prone to damage and is therefore not suitable. For this reason Pinion has the chain tensioner fixed to the transmission, which is generally better: 1. If it hits an obstacle, the chain tensioner can simply fold back and it is also protected by the rear tyre. 2. The position of the chain tensioner on the transmission enables greater contact of the sprocket, which extends the function of a chain guide, thus preventing the chain from coming off in rough terrain. 3. During installation the chain tensioner is automatically aligned to the chainline, which eliminates the time-consuming process of aligning it to the chainline.
Are trigger/thumb shift levers available for Pinion transmissions?
No, only the Pinion rotary shifter is available for shifting gears with the transmissions.
Can crank arms from other manufacturers be used with Pinion transmissions?
No, this is not possible, because the crankshafts in Pinion transmissions have a specific design. No other manufacturers offer cranks that meet the Pinion standards yet.
Can the Pinion rotary shifter be mounted on a racing bike handlebar?
Yes, but this only works with divisible handlebars, such as the Van Nicholas Divisible Drop Handlebar.
Can Pinion transmissions be used in combination with toothed belt drives?
Yes, if the bicycle frame is suitable for a toothed belt drive, this will be no problem.
Can Pinion transmissions be fitted with a ratio of 1:1 (e.g. 30 teeth front, 30 teeth rear) or even a reduction ratio (e.g. 24 teeth front, 30 teeth rear)?
Yes, this is possible and may be useful, for example for a 29" MTB that is used in extreme Alpine terrain. You can find the optimum secondary ratio for your bicycle with the ratio calculator, which is available from Pinion for every model of transmission.
Can chain rings and pinions from other manufacturers be used instead of Pinion products?
This is possible. However, a spider, available from Pinion as an accessory, is required for attachment to the transmission.
What applications are Pinion transmissions designed for?
Every transmission has been designed and optimised for the requirements of different applications. However, specific applications are not defined but only recommendations for the applications for which the various transmissions are most suitable in the view of Pinion. This is because, for example, the requirements of a user for use in flat terrain are quite different from the requirements for use in hilly regions. For more information on this topic see our Pinion Product Family or the current Pinion brochure.
Where can I test-ride and purchase bicycles with Pinion transmissions?
For a list of dealers who offer bicycles with Pinion transmissions see here.
Does Pinion offer factory tours and an opportunity to test-ride bicycles with Pinion transmissions?
No, the Pinion company premises are for production only. Contact a dealer for test rides or more information on Pinion transmissions. For a list of dealers see here.
What bicycle brands offer bicycles or frame kits with Pinion transmissions?
For a current list of bicycle and frame manufacturers see here.
I live in a country that is not in the EU and is not Switzerland. Can I purchase a bicycle with a Pinion transmission.
This is theoretically possible if there are any bicycle manufacturers in your country that offer bicycles fitted with Pinion transmissions. However, if there is not yet a Pinion distributor in your country who can service and repair transmissions and sell accessories and spare parts, you should be aware and accept that if your transmission is seriously damaged and cannot be repaired locally it would have to be sent to the Pinion factory in Germany for repair. You would be required to pay all expenses for shipping, insurance, packaging and customs in both directions, not Pinion.
What colours are available for Pinion transmissions?
Pinion transmissions are available in three standard colours (black, silver, blue) and six special colours (red, orange, green, titanium, gold). See your dealer or the manufacturer for the available colour options for your bicycle. Pinion colours are anodised coatings. There are no corresponding RAL shades for the colours.
What does a Pinion transmission cost?
Pinion transmissions are sold exclusively to bicycle manufacturers (OEM). Therefore, individual transmissions are not available to end customers as a separate unit. Pinion has no influence on the prices set by manufacturers. Bicycles with the P1.18 transmission currently sell from approximately €2500. Our new range of products means that bicycles with Pinion transmission will soon be available at lower prices.
Where can I get accessories and spare parts for Pinion transmissions?
You can purchase original Pinion spare parts from the dealer or bicycle manufacturer (direct sales) from which you purchased your Pinion bicycle. There are also online shops that sell Pinion accessories and spare parts.
Can a Pinion transmission be retrofitted to an existing conventional bicycle?
No, this is not possible, because the bicycle frame must be fitted with a special bracket for the transmission.
How frequently must the transmission be serviced?
The oil should be changed every 10,000 km or once a year. You can have this done by the dealer. The user can also easily change the oil following the directions in the owner's manual (hyperlink to owner's manual in the download section) or the corresponding service video on the Pinion web site (hyperlink to service videos). Pinion offers the practical P8900 oil-change kit for changing the oil. External parts such as sprockets, chains, derailleur cables and rotary shift rubbers are subject to wear, which may vary greatly depending on riding style, weather conditions, terrain and care and therefore may require replacement at very different intervals. Wear tends to be less than with derailleur gears, because the chain is not skewed with Pinion.
What oil and how much is used in Pinion transmissions? Where can it be purchased?
Pinion transmissions are filled with 60ml of fully synthetic Pinion transmission oil. The oil can be purchased from dealers or the bicycle manufacturer (direct sales) from whom the bicycle was purchased. Online shops that sell accessories and spare parts also sell Pinion transmission oil. The use of any other oil will mean that any warranty claims will not be accepted by Pinion.
Can the Pinion transmission be opened?
No! One reason is that the transmission housing screws are tightened to the yield point at the factory by an electronic torque monitor and cannot be used again after opening the transmission. Also because special tools are required for assembly of the transmission.
What warranty or guarantee does Pinion offer for transmissions?
The legal liability requirements apply for damage to material and workmanship. The liability period starts on the date of initial purchase.
Where can I find the gearbox serial number?
The 6-digit serial number of all gearboxes of the P-line is engraved on the right side of the case at the rear edge. In some cases, the number may be difficult to read when the transmission is installed, as part of the bridge to the chainstay obscures this area. The serial number on C-line gearboxes is located below the gearbox mount at the rear of the gearbox. The 6-digit number starts with "C". This photo shows you where the number can be found.
