wombat Posted September 10, 2010 Report Share Posted September 10, 2010 What's the method you use? Unless you have a shaftie. String line? Straight plank of wood or similar? One of those fancy laser sprocket and chain thingys? (ProfiCat) I personally use one of the laser sprocket and chain devices. I know my front end is a bit outta line and will get around to fixing it one day ( just a lazy bastard) Bob Link to comment Share on other sites More sharing options...
Strappy Posted September 10, 2010 Report Share Posted September 10, 2010 I tried it with a length of wood once, managed to drop the bike off the paddock stand and snap the gear linkage. Link to comment Share on other sites More sharing options...
originalracingsnake Posted September 10, 2010 Report Share Posted September 10, 2010 Never done it. PB rana feature on doing it though, I just found myself too lazy to bother. Link to comment Share on other sites More sharing options...
Harry Muff Posted September 10, 2010 Report Share Posted September 10, 2010 I use a tyre tread depth gauge to measure from the end of the swing arm to the spindle block on both sides. One of these chappies: Link to comment Share on other sites More sharing options...
fran9r Posted September 10, 2010 Report Share Posted September 10, 2010 I use a tyre tread depth gauge to measure from the end of the swing arm to the spindle block on both sides. One of these chappies: Thats only making the wheel square to the swingarm though. I use a maxton jig -basically 2 lengths of ally, you then measure the gap between the sides of the front wheel. Dead simple, you can usually just eye it up. Link to comment Share on other sites More sharing options...
Harry Muff Posted September 10, 2010 Report Share Posted September 10, 2010 Well if the swing-arm is pissed then you're in trouble anyway. It's always worked fine for me. Link to comment Share on other sites More sharing options...
fran9r Posted September 10, 2010 Report Share Posted September 10, 2010 Thats not true. As a production item, a frame and swingarm is subject to manufacturing tollerance the same as any other. You will find race teams have there new off the line frames jigged to get them as straight as possible. Unless you do that, setting the wheels in line is the next best thing.

burntout Posted September 14, 2010 Report Share Posted September 14, 2010 String line it - I checked the dealers handy work last time and the results agreed with them so it's certainly effective enough. Link to comment Share on other sites More sharing options...

krazyk Posted September 16, 2010 Report Share Posted September 16, 2010 I used a 2metre length of Ally, about 15 cm wide , bought in diy shop when I was laying the stones front of house, when I fitted the Gilles adjusters and just eyed the gap after using the Profi cat on chain.

Kawasakifreak Posted September 17, 2010 Report Share Posted September 17, 2010 Well if the swing-arm is pissed then you're in trouble anyway. It's always worked fine for me. I agree with Fran9R - most mass-produced frames are slightly out of line to some extent - particularly tube frames. Swingarms are just an extension of this error.

Gregorious77 Posted September 18, 2010 Report Share Posted September 18, 2010 I measure from swingarm pivot to wheel spindle, I guess if the pivot is pissed though this will not be that great. Link to comment Share on other sites More sharing options...

peter187 Posted October 17, 2010 Report Share Posted October 17, 2010 I use a straight piece of aluminium and the measurey measurey method. It's a lot easier if I can talk someone into helping me hold the straightedge. Link to comment Share on other sites More sharing options...
roastdinajima Posted October 17, 2010 Report Share Posted October 17, 2010 I *found* a couple of lenghts of 20x20mm ali at work wacked a couple of holes at suitable in one end and with some threaded bar long enough to go through a 180 tyre, i made this seems to do the job ok, although i'll need to *find* some longer threaded bar if i get a bike with a mans sized rear tyre Wombat if you want to borrow it i'm up on the northern beaches.

skyline Posted October 19, 2010 Report Share Posted October 19, 2010 I've been trying to figure out this technique - using string to measure wheel alignment: The bit at 1.25m threw me - whatdidhejustdo? - but I think I've got it. I'll give it a try on my bike once I can get into a bigger space. Link to comment Share on other sites More sharing options...
