Wheel alignment question

[Grant66]

Did the chain adjustment thingy this weekend (first time its needed altering) and thought I'd check the alignment. Used the string method, pretty easy and no major worries getting it 'bob on'.

Now for the stupid question, how far out of alignment does it need to be before its noticeable to the rider?

I'm assuming the tyre wear will be greatly increased but what symptoms are there? Is it just a sence of having to steer to keep the bike in a straight line or would you end up in a bush on a twisty country lane?

hi gajjii, cant help with the question mate but have one of my own.....can you explain this string thing to me please??

Haynes manual explains it well, but makes it sound overly complicated.

tie a 8ft piece of sting to a spoke of the rear wheel, take the length round the back of the rear tyre, wander to front (taking end of string with you) pull tight. As you move the string in and out you'll find the point where it touches both edges of the rear tyre (at this point, this is the direction the rear wheel is aligned to). Measure distance of string to the front wheel (if you use the lowest point of the outer rim you don't have to ensure the front wheel is perfectly straight).
Repeat on other side, ensure distance is the same. Not found a tollerance mentioned but its easy to get it within a mm.

ah cool many thanks....not seen this in the haynes manual will have a scan tonight (although your description is good!)

I have two straight pieces of box section that I bolt at the rear wheel, It does exactly the same as the string method, except you know it is straight and can measure left/right at the same time.

The box section cost me about £10, and it saves one heck of a lot of faffing. Next time I do it I will post a piccy

With the adjuster bolts being the same length. I take the screws out and turn them a very tiny amount till they bite then count the turns on each side to adjust the wheel.

doing absolutely nothing this afternoon, may just put that to the test.
seen guys do something similar to that wit touring cars, all the right kit though but essentially they were using a string.

yep ill be trying it next weekend......cleaned the chain this weekend as not done it since the bike was written off in november, and found kinks galore

the manual says between 20mm and 30mm slack...mine keeps going up untill its stopped by the frame...so way over the 30mm oops!...been a bit worried about adjusting it as not got a paddock stand but gonna see if i can borrow one and sort it next weekend. thanks for the info
