Stanchion swap
Permalink  
 


I've finaly ditched the DTR wheels and fitted some proper TDR wheels and forks Bike now looks a hell of alot different which is good....the down side is she's very twitchy in corners. This is because the forks are about 3 inches shorter, theres a smaller front wheel and the rear has been jacked a little which all increase decrease the head angle. The front wheels tends to dig in a little.


My bright idea is to swap over the stanchions with the DTR and keep the TDR lower legs. External diameters are the same but i'm not sure about the internal workings and i havnt taken any measurements yet. Has anyone else done anything similar?


Im going to run with it for the time being and she how she rides. If i cant swap the stanchions I may look in to milling a caliper bracket for the DTR forks

I hear that Cagiva Mito USD forks may fit but the steerer tube need to be pressed out and replaced with a TDR one. It you didnt want twin disc you could fit YZ/WR forks

I was looking in to the WR/YZ option last year but it would mean a new wheel, speedo drive, brake setup etc etc and at the time couldnt be bothered. Might look in to it again once i get this current setup sorted.


Seems the lower fork legs are the same length so the DTR stanchions are longer so from the looks of things it could be a straight swap Ill just have to fight getting the buggers apart.....i hear the lower fork bolt is a sod to undo!

I've got 4 of the buggers to undo so you can bet there'll be one that wont budge.


The manual says to use some dowel to wedge the insides....is there a nack to it?

Managed to wedge the internals with a broom handle. So now the DTR forks are in bit but i dont have a 12mm allen key for the TDR forks so i'll be out playing again tomorrow.


Had a bit of a revelation tonight...the DTR forks are only 1.5 inches longer than the TDR forks. Is it really worth the effort

Had to give in! I can get the DTR forks apart but the 12 year old TDR forks as soild


Gonna play with spring preload and dampening instead

I got some washers from b&q and ground them down to fit inside the stanchion. This have given about 15mm of preload but i still think it needs more.


Also notice that the front wheel is way out of true....
