Spin Doctor Digital Aftershock review

Spin Doctor is the house brand of online retailer Performance Bicycles, offering a full line of shop tools that includes everything from truing stands to multi-tools. The Digital Aftershock pump's name pretty much says it all – it's an aluminum bodied shock pump that has a digital pressure readout. Air pressure is displayed in tenth of a pound increments up to 100psi, and in one pound increments after that up to a maximum of 300psi. The display can also be switched to Bars or kilograms per square centimeter by pushing the rubberized button on the face of the pump, and there's also a pressure bleed valve to let out a pound or two at a time. The display turns off automatically after 80 seconds when no pressure is detected in order to preserve the life of the replaceable battery. Weight: 206 grams. Length: 11.4 inches (29 cm). MSRP: $69.99 USD. www.performancebike.com


Spin Doctor Digital Aftershock review
The Aftershock's digital pressure readout is easy to read, although the portion that displays the units of measure isn't quite as clear.

Removing four hex head bolts allows the readout unit to be removed in order to replace the battery.


Pinkbike’s Take:
bigquotesThe last digital shock pump that came my way turned out to have a battery that wasn't replaceable, a massive oversight that had analog pumps looking even more appealing. Luckily, the Aftershock doesn't suffer from that issue, and in fact, there really aren't any deal breaking issues to speak of. After a few months of regular usage it's still going strong, and the battery has lasted the entire time as well. The overall length is a little long for tossing it into a pack, but that does make it easier for the hose to get to those hard to reach air valves, and it helps speed up the inflation process due to the greater amount of air moved with each stroke.

Questions about calibration often arise regarding shock or tire pumps, but I've found that the best tactic is to use the same pump whenever possible, and to base final shock settings more off of sag and feel rather than the numbers on an LCD display or a dial. That being said, the Aftershock's readout agreed within a few pounds to the analog pump I compared it to, and its readings didn't vary during the test period. The readout is clear and very legible, although the lower portion where the units of measure are displayed is much darker, and can be hard to see in dimmer light. The pump's max pressure of 300psi may not work for bigger riders running the the RockShox Debonair that has a max pressure of 350psi, but for most users that range will be more than adequate. All in all the Digital Aftershock is a quality tool that makes it a little easier to accurately inflate a fork or shock.

 I bought a Fox pump before I knew the battery was not replaceable. A non replaceable battery on a $70 pump is bullshit, but I hope that Fox does right by their customers when the battery finally dies. Hey Fox, this is an easy opportunity to make yourselves look really good by doing the right thing, don't blow it.

 I won one of those pumps and the battery died after about 3 months. Then I asked them to warranty it. No response. Thanks Fox. P.s. That fork sucked too

 They'll replace it. I called them up and was informed they're coming out with a new and updated version of their shock pump. They said to hold tight and call back within the next couple of months and they'll exchange my defective pump for their new one. There's a whole thread on this:http://forums.mtbr.com/shocks-suspension/fox-digital-shock-pump-945414.html#post11874516

 The right thing was collecting the cash for the pumps. Anything else is not relevant. Please remember to be a loyal FOX supporter!

 I'll need an enduro toolbox to put this in

 Looks the same as the pump sold by Works Connection. It works well and the BATTERY IS REPLACEABLE. Do you hear that Fox?
  • + 1
 Yes it is the same pump works connection. I have owned one for about a year and it is a rock solid piece of kit. It is also smaller and lighter than my old dial type shock pump. Very high quality construction.

 I've had the spin doctor analog pump and has served me well for over two years now. Performance has a lifetime warranty on their stuff so if this new pump turns out to be a dud then they'll have no problem giving money back. I had one their tire pumps die on me and they gave me store credit after a year of ownership and i didnt even have the receipt anymore.

 Do you take it with you on the trail? I'm curious as this wasn't mentioned in the article above. I carry mine with me just in case or if I want to make adjustments. Seems like this wouldn't fair in my bag getting beat up with my other crap I carry.

 Best shock pump is the one comes free with your fork/shock
  • + 2
 Beecause..., missing your air pressure number by 2psi could cause a +/- 0.5mm diff in your sag or perfect World Cup DH time, but nah, my analog will go another 10yr. Thx anyway

 Some people are OCD about the consistent performance of their products. Chill

 I just jump up and down on my bike, if it feels too hard take some air out, too soft put some air in! I only use sag as a back up measurement!!
  • + 4
 Because a Monarch+ RP3 requires a 300psi gauge and pike requires less than 100psi gauge. This mean that you have crap readings when inflating the pike
Precision and repeatability is pretty poor on the low end of the gauge dial (most analog gauges are 2.5% of max reading, ie 7.5psi for 300psi gauge).

I choose the cheap way: I modified a shock pump with a low pressure gauge for the fork, problem solved.

 Without a zero loss check valve at the air chuck a digital readout is completely pointless anyway. You're still only going to know what the pressure was before you removed the hose and lost anywhere from 5 to 20 psi.
  • + 2
 Don't most shock pumps have both a schrader chuck and a valve depressor that you can actuate separately? (like this: goo.gl/SXFwRh) You unscrew the valve depressor first, which closes the schrader, then you unscrew the hose. The air you hear coming out is only from the pressurized hose. Unless this only has a schrader chuck.... which seems like it would be a shitty design for a shock pump.
  • + 1
 No, most shock pumps have a chuck exactly like the one in this review, which doesn't have a check valve. So when you unscrew it you lose an indeterminate amount of pressure. People get way to hung up on knowing exactly what the air pressure is in their shocks anyway. Sag is the only thing you should really look at, if your sag is where you want it then obviously you have the right pressure.

 @Satanslittlehelper I can't believe an idiot voted against your comments. I guess he was not very pumped by your wisdom.

Unfortunately not many shock pumps come with a chunk on their valve. I do think an accurate gauge is of a very limited use on a shock pump. The sag is I suppose, the measurement we all are looking at. And without a chunk on your shock pump it is more than likely that you'll have good fun. The Topeak Pocket Shock DXG is the only one allowed in our workshop. Better than the one you showed us the picture of -which was my pump of choice before the Topeak came out-.
  • + 1
 Yeah I don't think it's important to get a true pressure reading for the shock, since you're using sag anyway. But with the Topeak (or similar) design you can read and adjust sag without ever disconnecting the pump from the shock, because you know you won't lose any pressure taking it off. Not necessary, just convenient.

 Zero loss valves is are bullshit. No air is lost from the shock when removing the pump, the head of the pump is designed to let the Schrader valve close (sealing the shock chamber from the pump) before the hose pressure is released. Air pressure is always lost when putting the pump on the shock as once the head is screwed on enough to depress the schrader valve on the shock the air in the shock then fills the hose.
  • + 0
 No one said pressure was being lost from the shock genius. The entire point was that the pressure is being read including the pressure in the hose, therefore the reading isn't actually accurate. Way to jump onto a comment thread two months later and literally contribute nothing.
  • + 1
 The FOX shock pump battery can be replaced but you have to be willing to snap open the LCD plastic case. Don’t make the same mistake as I did by taking apart the pressure vessel as I now have a pump that READS the pressure but can not pump up anything. Buy this one or a Progressive Suspension Digital Gauge Shock Pump GP4-300 as they are great for adjusting and maintaining accurate pressures in challenging to setup shocks like Cane Creek DBAir.

 Now that's a sensible way to spend $70.

 All this is is a rebranded chinese blank. You'll see several companies with this exact pump. Works and Progressive are 2 that I can think of right now. Fox too I believe.

 I wonder if the "stubby" style air chuck on this will work with recessed valves. Like the one's on the Reverb and Command Post.

 That's looking WAY to fragile from my perspective. I'll stick with the Fox analogs I have had for years.
