Human specific geometry 

Because Knolly frames feature a continuous seat tube they allow for a full range of seat heights: on many other frames, the seat tube is either bent or interrupted by the shock allowing only a restricted range of seat heights (this problem is exasperated as frame sizes become smaller). Our frames feature both a continuous seat tube as well as a low “dropped seat height” - meaning the seat actually travels forward and out of the way - which allows riders of all sizes to get farther back on the bike when the terrain demands it. 

​For taller riders -  The ability to run the latest dropper posts is mandatory in order to achieve proper climbing height, and still be able to drop it down low(175-200mm). Running these posts (with long insertion depths) is impossible on interrupted/bent seat tube designs. In fact, Knolly is one of very few bikes that can actually run the latest 200mm dropper posts. Our seat tube angle is optimized to make sure the rider is in a very effective pedaling position while climbing with the added benefit that the top tube length effectively grows when the seat is raised which allows the rider to have increased reach when necessary (without placing the rider "behind the bike").  

 

For smaller riders - Frame fit is an absolutely critical part of the purchasing process. Proper stack-height and stand-over measurements can be a make-or-break proposition. Add a longer shock into the mix, and most frames start getting too tall to continue the conversation. One of the side benefits of Knolly's Fourby4 design is the ability to accommodate smaller riders, even with up to 170-200mm of rear suspension travel. This keeps the shock mounted low which means we can drop our top tubes for better stand-over clearance. It also means the center of mass on the frame is low and that equates to exceptional handling in technical terrain. Smaller riders can run a 150mm dropper post on our bikes due to the low stand-over height and straight seat tube. 

Geometry - Is the single most important factor that determines how a bike is going to ride. A simple 1 degree difference in headtube angle can make the difference between feeling ‘sketchy’ or confident. We design all of our bikes to make the rider’s position on the bike a source of confidence, since when you’re feeling confident, you’re having fun. All Knolly models provide a comfortable, confident ride by utilizing a few key concepts:

Standover height - We design all models in all sizes to have very low standover measurements. This helps the rider feel ‘in the bike’ instead of ‘on top of the bike’. Low standover also helps with cornering and maneuvering, allowing the rider to lean the bike over while maintaining proper center of gravity.

The 'Attack Position' - This is the position you assume when you are out of the saddle and ready to descend. This must be a position of total balance, where the rider can shift weight in any direction equally, and manipulate the bike as terrain and obstacles dictate. Proper balance is achieved in design by having reach measurements that coincide with the total length of the bike. This puts the rider in the middle over the bike, feeling confident.

 

Front end stack height - Another key to proper geometry. All Knolly models feature very short headtubes, which keeps the front end stack height as low as possible. This allows the rider to get over the front wheel, which is a key to proper traction and balance. This concept’s importance becomes magnified when the wheel size starts to grow. The headtube on our 27.5 models are among the shortest in the industry, ensuring that the rider can still get over the front of that taller wheel. Short headtubes also allow for longer travel forks that won’t throw intended geometry out of balance.

Chainstay length - This is a highly debatable topic. It seems very trendy these days to have chainstays that are as short as possible. Here at Knolly we focus on balance. We design each model with stability and predictability as top priorities for all types of terrain. So depending on the model, you’ll see a chainstay length that will be appropriate for maneuvering and stability at high speeds.

 

So when you combine some of the industry's lowest stand-over heights (on all frame sizes) with our continuous seat tube, and our 'way-before-it-was-cool' long/low geometry, the Knolly simply feels right.

Frame design Ethos

The ethos of Knolly’s frame designs is to allow the rider to transition effectively between a highly efficient pedaling position and the “attack position” required for aggressive riding (and be comfortable anywhere in between).

The key feature allowing this seamless transition is the offset straight seat-tube, which positions the saddle in an efficient & comfortable climbing position, then moves the saddle downward and forward in the dropped position.

 

Knolly pioneered this technology back in the early 2000’s, and it’s now becoming the de facto way to design most modern mountain bikes. This design element is critical in allowing maximum rear wheel travel while keeping rear suspension elements and the rear wheel away from the seat tube under full compression.

Offset Straight seat-tube advantages are:

  • The actual seat-tube location can be designed so that the bike has a steep effective seat position when pedaling and / or climbing (74.5°– 75.5° effective seat tube angle). (The blue dotted line running from the BB to the seat in the illustration below)

  • The saddle not only lowers, but moves forward when dropped, allowing more room to maneuver above and behind the bike (The red dotted lines in the illustration below).

  • The longest possible dropper posts will fit into the frame because the seat-tube is straight and uninterrupted: many of our frames will support 175mm and even 200mm dropper posts. It’s commonplace for our smaller riders (5’1” – 5’2” in height) to be able to use 150mm dropper posts in their frames. (The green dotted line in the illustration below)

  • No possibility of rear wheel / rear suspension elements colliding with the seat tube / saddle under full compression.

  • Amazing stand-over clearance.
