Since my last post I have been away for an off road tour in Sardinia, Italy.
The trip took me roughly down the centre of the island with over 50% off road, some of it rather difficult. (I would not recommend doing it alone on a large bike)
My wrist was still not 100% and I used my ad hock clutch lightener throughout. But I was loosening it during the ride as my wrist got stronger (the exercise actually accelerated my recovery ;-)
Even though the wrist is still injured and I am not at 100% recovery, I can ride without pain.
The clutch is fine after the tour. Occasionally, during riding days, I would feel the clutch case to see if it was overly hot. There was not much more I could do to monitor the situation.
I spoke to my mechanic before the tour about the issue that were brought up by
, his opinion is that this part is nothing to worry about. It will outlive the clutch even with this mod, and can be inspected each time the clutch is replaced.
The more I use this mod (the more intrusive I set it) the shorter the life of the clutch will be, resulting in more regular inspections of the release bearing.
He told me a new clutch is only about €100 and pretty easy to replace, so save your wrist and don't worry about the clutch wear.
For a mod that is none destructive (no permanent parts of the bike have to permanently modified to install this mod); is easy to install and de-install on the road side; is adjustable to quite a fine degree (counting the number of lock nut turns); and very compact and quite light to carry along on a tour, it is a no brainer for anyone that has troubles with the left wrist and the clutch.
Off road riding requires a LOT more work with the clutch hand. On a tough off road days, many riders will feel the left forearm fatigue I think. This mod will definitely help to lighten the load on the wrist and allow you to enjoy the ride much more.
I can imagine that for bikes with no traction control, this mod could be used to not only lighten the clutch but to also dial in a minimum level of fixed clutch slip on really gnarly terrain. Since it is so easy to adjust, install and remove, I could image tweaking it through a riding day to suit.
Would be cool to even have some handlebar accessible adjuster where its effect could be dialed in on the fly!
