Yes the spacer size does not change the spring rate but the pre-load. I have tested many different spacer sizes (pre-load) and it makes a big difference, especially in a rocky section such as a stream bed. For me the stock spacer makes my fork action stiff, while the shorter spacers make the forks more supple, absorbing more, creating a better handling bike. The trade off however is easier bottoming. Coming over a big log with the stock spacer is great. With the shorter ones the forks will bottom, not harshly though, and make the landing more difficult. I have had best average results with a spacer about 3/4 the length of stock. Thanks all for the input. I am interested to see what others where experimenting with and their findings. The 175 is a great light bike and I am trying to reach it's full potential.
