  • Can I fit the General Lee cassette on my bike?
  • General Lee cassettes are only compatible with XD hubs. In order to know if your hub body is XD or Shimnao check if it has a threaded section near the spokes. If there is a thread, then is an XD hub and therefore compatible with our cassette. If it does not we offer the General Lee kit, compatible with Shimano Hub bodies which replaces the last three cogs of your cassette to get to the 42t sprocket without loosing performance.
  • Do you have any tips to get the maximum out of my cassette? 
  • The General Lee cassette is a precise work of engineering and manufacturing, it is made to be both light and strong and therefore needs to be used with understanding. Our cassette is made to hold strong in the most common gears and give an extra advantage on the climbs. If you want your cassette to last longer try to avoid using the three large aluminium gears unless it is neccessary. It is also important to be smooth in the gear changes, when changing gears the chain puts a big amount of stress in a sigle or a pair of teeth, at this time, if we pedal hard it is possible to break the teeth (this will not go as warranty).
  • My chain gets noisy and skips teeth on the 9t, what should I do? 
  • We offer an eccentric derailleur pulley to solve these kind of problems. The ADV pulley improves overall shifting performance by moving up and down the cage. The eccentric pulley has been designed to move upward towards the cassette when the derailleur is on the smaller sprocket, and downward when on the larger sprocket (with the cage extended). This allows for a tighter wrap of the chain in the 9t and eliminates noises.
  • The three large cogs are worn out, do you sell any replacement? 
  • Since the last three cogs are aluminium and the chain is made of steel it is normal to see wear after some months of use. We sell the last three cogs alone as a solution to wear, to buy them please ask your retailer. To replace the last three cogs you would need to separate the Aluminium cogs from the steel sprocket using a flat screwdriver, or other thin tool to use as lever. To install the new cogs, make sure the pins are well matched and seat well in the holes, then hammer it down with the teflon hammer until it is leveled and secured.



  • How do I determine the number of teeth I need?
  • Chainring size is usually determined by experience and taste, however there are tools that help us understand which size would fit us better. GEAR CALCULATOR
  • How do I know what BCD I need? 
  • Most manufacturers include this meassure in their product's technical information. However, if you do not have any references you can measure it yourself. BCD is measured on the spider's bolt holes, taking the center of the hole as reference measure the distane to the center of the opposite bolt (lease note if it is simetrical or asymetrical).
  • What is the point of the oval shaped rings? 
  • Our Track chainrings offer a better performance when pedaling by distributing the máximum and minumum force points in accordance to each pedal stroke. To achieve so we have enlarged the distance between the axle and the teeth when the cranks are in horizontal position (maximum force) and have reduced this measure in the vertical position (minimum force). For example: a 30t track chainring would feel like a 32t when the cranks are horizontal and like a 26t when vertical.
  • What is offset? How do I know what offset I need? 
  • When switching to a single chainring setup chainline becomes crucial. Depending on the cranks you might or might not need to run a chainring with offset. Offset is the distance from the crankarm to the teeth (measured horizontally). Sram GXP cranks, for example, would need a chainring with offset, however BB30 cranksets require 0 offset. 



  • Why the 12k pattern of the Luke handlebar?
  • By increasing the size and fibers of carbon we can improve its absorption qualities. The Luke offers a very unique design that allows for a smoother and less shaky feeling on the bars. The wider fibers twist and flex more than the smaller 3k fibers making it better for shock absorption without compromising its strength.
  • Can I cut down my bars/post? 
  • Of course, both the Luke handlebar and Bo seatpost are designed to be cut to your own lenght when purchuased. The bars come with premarked cuttting lines on the 3k carbon ends to ensure a better result. The seatpost does not have any marking (we recomend to leave a minimum insert of 100mm).
  • How tight do I set the stem and brake bolts?
  • The stem bolts should be tighten to a maximum of 5Nm, while the levers and shifter bolts should not pass 4Nm according to factory recomendations. It is common (and recommendable) to tighten the brake levers just enough so that they can rotate in case of a crash, this avoids the lever from braking in a direct impact.
  • What's the point of a 500mm long seatpost?
  • As with the handlebars, we wanted to offer a posibility for everyone with just one size. Frames are now getting lower and seatposts need to be longer, 500mm was a reasonable lenght for tall riders with low frames, while it is always possible to cut it down for shorter riders when purchased.
