Mountain Bike FAQ
This page has the FAQ for our mountain bikes.
If your Lenz frame has a tapered head tube, your head tube has an upper inside diameter of 44mm and a lower inside diameter of 49mm. The headset specs should be as follows
- Upper Cup – ZS44/28.6
- Lower Cup – EC49/40
We love Wolf Tooth and Cane Creek Headsets. If you go with a Chris King, they call it the Inset i3.
- All Lenz Sport frames are 100% handmade-to-order. Quality of craftsmanship and riding performance is the number one focus at Lenz Sport, We take pride in the quality of every single frame we make, and we never cut corners to speed up the process.
- Frames are built to order, but we often have the frame you need in stock. Please email us for current availability. We will provide you with an estimated lead time. Sometimes it takes more time than we expect, and sometimes less. We do not guarantee delivery dates until the bike is complete and ready to ship. General average lead times are 3-6 months for frames that are made to order.
- We generally start our last batch of mountain bikes for each year in September and then we start on SkiBikes for the winter season. If you order a mountain bike after that, and it’s not one we have in stock, it will be made during the next batch of frames starting in January of February and typically finished in March or April. The best time to order a bike to be sure you have it for the spring season is before January.
**all deposits are non-refundable and lead times are estimated, not guaranteed. Lenz Sport is dedicated to building handmade and extremely high quality bike frames, wheels, and full bikes. We fabricate every single part of the frame in house down to the bolts, dropouts, pivots, and cable guides. The manufacturing process is very unique and can vary in the amount of time it takes. By ordering this frame, you are getting something special and different from what any other company in the world can offer. We greatly appreciate your patience throughout the process and we look forward to delivering your bike. We cannot provide constant updates, but we will let you know when your frame is almost ready for power coating so we can finalize your custom color choice. Until then, let us know if you want to make any changes to your component choices or frame options.
Current model Lenz Behemoth, Mammoth, and Lunchbox frames with the 16.5″ chain stay length work best with a Sram, Praxis, or Raceface crank with a 26-30t ZERO offset chainring.
(applies to model year 2019 and later)
The Mammoth can be converted from 110mm rear travel to 140mm rear travel by ordering replacement control arms (rocker arms)
The Behemoth can be reduced from 140mm travel to 110mm rear travel by ordering replacement rocker arms.
The Lunchbox and Sesh cannot be converted to a different rear travel.
If you have a Fatillac originally built with 4″ (110mm) or 5″ (140mm) rear travel, you can convert between 4 and 5 inch by swapping rocker arms. If you order with 6″ travel, you cannot change it. Go big!
The Behemoth, Mammoth, and Lunchbox are designed for tires ranging from 2.4″ to 3.0″. Any tires in that range work great. You can order any of these bikes as a 27.5 or 29er or a mullet (27.5 rear and 29 front)
The Fatillac is a little more complicated. With a 27.5x50mm wide rim, the max tire size is 27.5×3.8″ . With a 65-80mm wide rim, a 27.5×4.0″ is the max tire size. The Fatillac will also work with a 29×2.4″ to 3.0″ tire.
The Sesh works with a 27.5×2.4″ to 3.0″ tire.
No. You can use anything from 2.4″ to 3.0″ on our “plus” bikes. We love plus tires, and they make a lot of sense for the trails we have here on the front range and western slope of colorado. That doesn’t mean they are the best thing for every person in every situation. Our bikes ride great with any size mountain bike tire. The 2.5″ range is great for fast smooth flowy trails since it lowers the bottom bracket a bit and you run the tires firmer for more speed. The 2.6″ to 2.8″ range is great for enduro style riding and if there is mud. The 3.0″ tires will dominate on chunky technical trails or those that are very rutted out and rugged.
Absolutely. Our full decal kits are $30. Please Contact us for more information.
The answer is a little more complicated than a simple ‘yes’ or ‘no’. Here’s why:
In order to repaint a frame, it has to be stripped down to raw aluminum first. That is not something that we are set up to do, and it would be very expensive to have us do it. We aren’t saying that it can’t be done, it’s just something that we don’t do in our shop. However, there are a lot of places that will strip your frame if it is disassembled and all of the bearings and bushings are pressed out.
With that said, once your frame is stripped we should be able to re-powder coat it and re-assemble it for you. It will still cost a little bit as we will have to prep it before powder coating, but it won’t be as bad as if we had to strip it as well. Your best time to do this is in the summer when we are not in peak skibike season; even then we would suggest allowing several weeks for us to get it done.
