Question about Cycling
Hi, I have a Raleigh Kalahari mountain bike (UK Model) with Shimano 21 speed derailleur, with Altus C10 trigger shifters which are beneath the handle bars. For health reasons I need to use it to get fit, but on trying it, the screw on the bottom of the trigger for the rear cog set dropped out and while I have put a new one in, I can only change by 2 or 3 lowest cogs. When I adjusted the tension of the cable I could get the top 3, but not the range of 7. It seems as if the trigger itself is faulty, only moving the cable a little.. Can I get into it and see what the problem is, in which case do you have a tech drawing, or does it have to be replace? What do they cost to replace?

The screws on the derailleur set the positional limits for the derailleur; if your description is accurate and it is always one position behind until the middle gears, I would guess it is not these screws causing the problem, but rather the cable tension is a little to low. There is a typically a knurled knob on the back of the derailleur that can adjust cable tension. Unscrewing it a little will tighten the cable. There may be other adjusters if you follow the cable up to the shifter. Try changing it in small increments (eg 1/8 to 1/4 turns) and go through shifts from high to low before determining if it is helping or not.

There is a limit screw on the body of the derailleur that you have to back out slightly. You can tell which one of the two it is by watching carefully as you adjust it. It takes a phillips screwdriver.

The problem lies in cable. Check out what make of front derailleur (cog shifter) you have (Shimano, SRAM, e.t.c.). Then visit the manufacturers website and check out for technical info and settings.
