I have a sort of rare Totem Shockman 29er bike, which as far as I know is assembled in my country by another brand as a lower entry point bikes. Through the two years I've had it I replaced some pieces for better ones, and now I was thinking about the rear shock; it has a stock KS Exa Form 290 coil shock (http://www.kindshock.com.cn/en/product.asp?id=164&show_list=1) which measures 150mm eye to eye and has 30mm of travel, which is not terrible but it's not entirely good either and had to send to my local store yesterday because of very loud creaks on it. Having only 150mm eye to eye, I have a lot of questions:
- Is there any coil shock better than this one that would fit?
- Should I pick an air shock instead? Would that be worth it and a noticeable difference?
- Would a RockShox Monarch RL (152x31mm) fit properly despite the few mm difference?
- Is it possible to fit something slightly larger, let's say 165mm shocks or would that be bad for the frame or the bike in general?
Sorry for all the questions, I was a complete rookie when I bought this bike and I'm still learning a lot every day, and thanks for your help.
