Jones Bikes Unicrown Forks 

Thank you!

I will really be happy for you when you do

Big tires have less drag, ride better and have no issue with hitting road pot holes at high speed. Especially with the long wheel base geometry. Check out this touring bike: instagram.com/p/Bu_vIAcgCRN/ see the tires work fast road and bumps ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-bJ8LbYh4U9Y.html

@@Veloperator Why do big tires offer less drag and is pressure important: so would you increase the pressure if you have 30km of pavement until the next section of single track? Or do you just set them at 15PSI most of the time and ride?

When riding with wider rims and tires, you can run lower pressure so bumps are absorbed better letting you roll with less resistance. I run the same pressure (about 12psi) on the road that I run for rough off-road riding. Increasing the pressure on the road would give a rougher and less efficient ride.

Hi, Bar end shifters can fit but I do not recommend them because they will be harder to reach, the cable will make it harder to use the right grips and the shift lever will hit the ground if you lay the bike down... Here is the H-Bar manual with what you need to know about installing and setting up the bars to get the best ride: www.jonesbikes.com/content/Jones_H-Bar_GUIDE_web_v3.pdf

Great to hear that you’re enjoying your LWB! I don't recommend using a SWB fork on a LWB frame. You may be feeling what is sometimes called "self steering" from how light and easy the steering is. It does not take much effort to initiate a turn with this geometry. Also, too much or too little air pressure, especially with the smooth tire can give a self steering feeling. I recommend 10-15 psi, on road or dirt with these bikes. Jones bikes have lower trail and less flop than most mtb bikes. When designing the LWB, I wanted a bike with a longer wheelbase and bigger wheels. I also wanted to keep the quick handling and fit, with short reach to the bars and a slack seat angle like my Jones 29er and SWB bikes. To do this I increased the chainstay length, slackened the head tube angle and increased the fork offset. This increased the wheelbase while keeping the fit almost the same as on the SWB. The big increase in fork offset reduced the trail measurement to a number that is less than with the SWB! This kept the handling quick with light steering even though the LWB has bigger wheels and longer wheelbase. It's great at low speed and track standing. Other bikes with less fork offset and slacker head tube angles will have much more trail, which also means more flop. The SWB fork is shorter and has less offset for the smaller wheel and the shorter wheelbase of the SWB bike. Using an SWB fork on an LWB would lower the front end, steepen the head tube angle and increase the trail a few millimeters not reducing flop. Jones framesets (frame and fork) are designed to work together to give you the best ride. Enjoy our rides! Jeff

@@Veloperator Thank you so much for the crash course in fork rake, trail and offset! Yes my LWB self steers a bit but it's not objectionable. Per your explanation I'll keep it as designed. Thanks again!

The length from lower headset to the axle is much shorter with this fork than a suspension fork or a suspension corrected rigid fork, and the increased rake/offset is not that much, but head tube angle also matters... Headsets are very durable and this is nothing to to worry about. Call me if you still have questions about this.

Thank you for the answer. I guess the reason for the rake is that it is flexible.

@@cccpkingu The reason for more fork rake is to reduce the trail measurement and put the wheel out front more (increase the front center). Almost all bikes have fork "rake", also known as "off set". This all affects balance and handling. This is not a suspension fork and it is not designed to be one. More info on bike rake/offset here: en.wikipedia.org/wiki/Bicycle_and_motorcycle_geometry

The unicrown fork preforms the same when used with a Spaceframe.

We expect them to be back in stock in early 2023. Put your email to be notified on the product page.
