The Halo Spin Doctor Freehub Cassette Body is a replacement unit for Spin Doctor. 8/9 Speed Shimano HG type spline compatible.
Important Tech Notice:
1) Lay the wheel down, with freehub facing up.
2) Tip at about 20-30 degrees.
3) Apply approx 5 drops drops of thick grade oil to the inside edge of the black body whilst gently rotating. (Do not use an excess of oil, as this could leak out later and effect your brake performance)
This oil should then be able to run down inside the small gap between the black body and the main body.
Continue rotating and, eventually you should hear a marked difference in the pawl noise as the oil enters the inside of the pawl mechanism area.
Note: As far as frequency of lubrication goes, this should be carried out pretty much inline with lubricating your chain.
Push-in the Freehub injector tool into the end of the freehub and apply grease into the tool via a grease gun, until you can see a small amount grease purging out of the backside of the freehub.
Grease injection will provide longer lasting lubrication.
New series Spin Doctor rear freehubs have genuine Finish Line TFG37 grease packed inside, plus a lube hole concealed under the cassette cogs. To lube the pawls and bearings, simply remove the cassette cogs and insert a grease gun pointed nozzle and squeeze ! (no need to pull-off hub end seals.)
What are wheels?
Wheels are probably the second most important part of your bike, after the frame. A lot of the bike’s riding characteristics come from its wheels.
Who needs wheels?
A wheel upgrade can make a massive difference to your bike. Because of this, you might consider a new set of wheels, even if the old ones aren’t worn or damaged.
What are the choices?
Mountain bikers choose their wheels in 26in, 27.5in or 29in size, depending on what their frame is built for. Road bike wheels are 700c. Beyond this, there’s a dizzying array of rim material and depth, spoke type and hubs galore – enough to make your head spin faster than your wheels.
What should I buy with them?
A wheel upgrade always deserves a lovely new set of tyres. These too have a massive impact on how your bike rides.
There are several approaches to buying wheels – you can buy a full wheelset, for perfect pairing, or you can take a modular approach, picking hubs and rims before having a new set built to your specification.
