Tire pressure

As a starting place, we suggest these pressure ranges:

27.5 x 3” on 50mm rim: 11-16 PSI
29 x 2.5” on 50mm rim: 14-20 PSI
29 x 3” on 50mm rim: 10-15 PSI

Heavier riders — especially those in rocky areas — will want to start on the high end of this range, and lighter riders on the low end, but you’ll need to experiment. In any case, it’s a good idea to check your tire pressure before each ride, and be sure to use an accurate gauge because few floor pumps have the fine measurement and accuracy that you’ll need at under 20 PSI.

Seatpost and seat tube area

Your bike uses a 27.2mm seatpost. For Jones Plus LWB frames, we usually recommend a zero-offset seatpost. Some taller riders will find that they want a setback seatpost on the Plus LWB. Steel frames use a 31.8mm or 32mm seatpost clamp. Your frame requires 100mm/4” of seat post in the frame. Any more than that can be cut off to save weight and make it possible to lower the seat more.

Drive train notes

Your Jones Plus frame is designed around the Boost standard, and must be used with a Boost crankset. Boost cranks position the chainrings 3mm farther outboard than standard cranks, and are key to getting proper tire clearance with 29 x 3” tires on the Jones Plus LWB. As long as you use Boost cranks in a double (2x) or single (1x) chainring configuration, you can use any style of drivetrain and combination of gears on the bike. In addition to the Boost crankset, you will need a 148x12mm (Boost spacing) thru-axle rear hub. This combination allows us to use cranks with a low Q-Factor (also known as tread), while being able to use tires up to 3.25”wide.

Cleaning

Don’t pressure wash your bike! It blasts grease out of bearings and replaces it with dirty water, which just doesn’t lubricate them very well. Instead, if you have to wash your bike, use a low pressure garden hose and some dish soap. Put some soap in a bucket and use a soft brush to scrub the bike, before gently rinsing it. Try to avoid the bearings—especially the bottom bracket and hubs—and be ready to take the wheels off and clean everything very thoroughly afterward! Re-lube the chain and dry the bike off after washing it.

Lubing the chain

This is a basic, but very important and often-overlooked area. Following this technique will give you a well-lubed chain, and won’t contaminate any other parts of the bike, which is very important. Make sure not to use spray-lube because overspray can get on the brake rotor, which will contaminate your brake pads, making the brake almost useless.

If the chain is very dirty, use a stiff brush to scrub it off. If you really want to get it looking new, you can remove the chain or use one of the many chain cleaning tools available to degrease your chain. The reason not to do this is that getting the degreaser completely out, and lubricant back in is very difficult. Therefore, it’s often better to just use lubricant to clean your chain, as described next.

Once you’ve gotten the surface gunk off, shift into the big ring (if you aren’t using a single ring in the front), and a small cog in the rear and, while you pedal the bike backwards with your right hand, apply lube from a squeeze-bottle just in front of the rear derailleur pulley until you can see that the full length of the chain has lubricant on it. Alternatively, you can put a single drop of lube on each roller of the chain.

After applying lube, continue pedalling backward for a minute or two to work the lube into the chain, then, using a rag, wipe the chain off while you spin the cranks backwards. Try to get all of the lube off. If you really want to flush your chain and clean it more, you can simply repeat this process.
