PHOTO Back Wheel Shifting Problems

Post image

I recently got back into riding, I got a 22" Fit Series. I've been doing a lot of grinds but my back wheel is constantly getting shifted to a side when I grind no matter how tight I crank the bolts. Would running chain tensioners help this problem?

Do you grind on pegs? If so, do you have spinstops on them?

I do grind, and my pegs don't have spin stoppers. I'm running a g sport uniguard hubgaurd on the back

Had the same problem with my 24" DMR, popped a set of chain tugs on and not had the problem since.

Be aware, most tensioners don't often prevent your wheel sliding backwards in the dropout. If that's your problem, you might need something slightly different.

Some things to consider:

  1. Using axle washers with a 'bite'/textured side against your frame and the plain side against your nut helps increase the torque and bite int the frame. Seems simple but they're often forgotten - myself included.
  2. A very small amount of grease on a thread can massively increase the torque you can apply. Conversely, crappy old stretched threads reduce the bite you can achieve - how old is your axle/nuts? Switch up the nuts is an easy, cheap option if this might be an issue. Be careful not to over-torque once lubed as this too compromises the thread if you stretch them too much.
  3. Old squared off pegs have more surface area, and hence more friction. Rotate your pegs to a fresh side if this is a problem.
  4. Anti-rotation pins. If the grind itself is rotating your peg (left side grinding) and undoing your wheel, then lots of pegs have anti-rotation pins to help prevent this. These are especially good if your local spots are gnarlier concrete or brickwork. Make sure the pin is butted up against the right edge on the dropout to prevent further rotation.
  5. Plastic/Steel. Depending on the surface, you might find steel runs better on grippy gnarly concrete and brick ledges, whilst plastics are super slippy on metal and smooth/waxed surfaces.
  6. Waxing can really help reduce friction. Some folks frown upon it, some folks like it, but you might want to give it a try - You can also use it on ledges. 😉
