I have had the Sport Gravel Drive Floor Pump for a couple of years now. The stock screw on pump head was horrible / awful / terrible / no bueno. This Presta-only head is a beautifully machined product that works very well. At $30 it should be wonderful, and it turned a $50 pump into an $80 pump so it only gets 3 stars for value. But if you have a Sport Gravel Drive Floor Pump (or any other Lezyne floor pump with that terrible screw-on head) and you don't want to just throw it out, this is the fix as long as you only need it for Presta valves. Installation is easy. Just cut the tube as close to the old head as possible, lubricate the inside of the tube, and install the new head.
For cycling repairs you canb either torque things or go with your gut - the problem is that going with your gut can end with cracked carbon or something that is too loose. The kit includes a bunch of bits, and a T handle ratchet that can be assembled in many ways. The torque tube is used to tighten things to a specific torque, and there is an alternate tube that is used for loosening. When you loosen you do not want to use the torque tube - if you go past its limits, you will ruin the torque tube. The package is compact so you can carry it, and there are plenty of bits to get the job done
As far as floor pumps go..,these are pricey. That said'I really wanted to try out all the great features. The pump comes ready to clip onto a presta valve with the easy to use Hiro Chuck. The Hiro Chuck can be removed, leaving a Schraeder Chuck. The gauge comes in automatically, and is very accurate. Fantastic parts availability and Warranty. The hose is perfect'it can be secured neatly for transport. It is long, and since it is attached higher up'it can reach your tires, even when the bike is in a stand or bike rack behind your car.
The version I received has a quick connect Schraeder Chuck. It connects to the Hiro quickly and easily, and you can twist the Hiro in a bit to snug up the connection. You can fiddle with the knurled top to adjust the grip of the rubber Chuck liner' and with a little practice'it is very easy to get connected and air up. Try not to open the presta valve more than a turn to a turn + 1/2' that makes for a clean disconnect without air loss from the tire. You will still air release from the hose.
Enthusiastic to be able to keep this pump serviced and performing to peak level for many years to come.
I'm completely new to using wax on the chain. I got interested in it because I got tired of cleaning the desert and road grit from my chain every time I ride. With the wax, the chain stays clean, I just have to throw it in the wax pot every 300 miles or so. The company has very nice instructional videos, which made it easy to do without any prior experience. The wax pot is pretty low powered, so don't expect to have melted wax 10 minutes after you turn it on. On the day I know I'm going to cross my 300 mile threshold, I just get the wax pot warming before I ride and the pot is ready to when I'm back. I use the reusable quick links, which makes it a pretty easy process to get the chain on and off.
