Re: Clinchers: steel bead v folding

a (relatively) old timer fellow cyclist friend of mine swears by hanging even a clincher in his garage for some considerable time before use. i suppose it's a carry over from the days of maturing tubs yes but wonder if people generally still have tyres in store (in the dark) in readiness. i do! :D ...

Re: SRAM A2 Automatix; introduction to the internals

pretty much any grease is better than none for the gears; however for the pawls and the bob-weights a thicker grease might be too viscous in cold weather. If it isn't too cold where you are a #0 or #1 grease might be OK through the whole hub. Since the gears are quite well separated from the rest o...

Re: SRAM A2 Automatix; introduction to the internals

it certainly is not too complicated inside. BTW it isn't a bad idea to remove the RH cone and put a load of grease in there for the planet gears themselves; I'm not sure it will migrate into this part of the hub easily otherwise. cheers What grease would you recommend for the planet gears? The stuf...

Re: SRAM A2 Automatix; introduction to the internals

I wish I would've taken pictures of my non-coaster hub when I took it apart yesterday. It has a plastic spacer in the space where the coaster version of the hub has the coaster brake assembly. The plastic spacer slides off the hub, and has five tangs that engage the low gear pawl assembly. I would t...

Re: SRAM A2 Automatix; introduction to the internals

Keeping my fingers crossed, too. I think I will tweak mine slightly. I may shoot for a minor jump from 11mph to 13mph. That would allow me to really spin the pedals the way I like. Thanks again for showing how easy it is to modify the shift point! EDIT: I just got back from a test ride after modifyi...

Re: SRAM A2 Automatix; introduction to the internals

Terrific blog post! Your description of unwinding the shift spring will prove helpful for many people, including myself. You make the spring adjustment sound much simpler than what can be found in other places. A question... You have a picture of the shift spring alone. Does that picture show how yo...

Re: SRAM A2 Automatix; introduction to the internals

I got my 22mm cone wrench today. I removed the internals from the hub shell. I found nothing obviously wrong, other than there being very little lubrication on the bearings. I had noticed play in the bearings before taking the hub apart, but didn't see any damage to the bearings or bearing races. Th...

Re: SRAM A2 Automatix; introduction to the internals

22mm (or 7/8") flat wrenches are needed to remove wheels and other tools from many angle grinders and routers; I'd suggest that a trip to a good tool store might be useful. The rattle could well be the centrifugal weights inside, or the pawl control plate. Note also that the high gear drive ri...

Re: SRAM A2 Automatix; introduction to the internals

I have a SRAM A2 hub installed on my commuter bike. I have the freewheel version. I've noticed a rattle in the hub since new, and want to make sure it isn't a defect or problem with the hub. I hear the hub when coasting over bumpy surfaces. When pedaling, while the hub is engaged, I don't hear the r...
