I've a prob. Not sure what to do to fix it.
It's a new bike. Giant Escape R3. [[some Japanese]]
F. Derailer - SHIMANO T301 31.8
R. Derailer - SRAM 3.0
Shifter - SRAM 3.0 TWISTER 8S
Gear - SHIMANO HG40 8S 11-323T
-On any of the 3 front cogs -
If I pull the (right) Gripshift knob/changer slightly beyond 1 (lets say, towards imaginary 0), the chain shifts into gear 1, but the moment I let go, it wanders back into gear 2.
When I slide the gripshift into 6, the chain shifts to gear 8.. so 7/8 on the gripshift don't do anything.
Gear 1 --> 2
Gear 2 --> 3
Gear 3 --> 4
Gear 4 --> 5
Gear 5 has become 6/7/8 (no movement when shifting into 7, or 8)
I noticed there's slack on the cable when the gripshift is on gear 8, and the gripshift knob moves loosely.
Does it wind down to the B-screw/H-screw/L-screw adjustments?
Any ideas/suggestions are much appreciated.
