Can you adjust from 100mm to 80mm?
 
Well, I searched for this on Google and got like random links. I want to know if I wanted say a Rockshox XC30 or XC32 or Suntour XCR, can I adjust from 100mm to 80mm? The frame I got from eBay (WD Cycle Elite), the seller says the fork supension is either 80mm or 100mm. By the way, I have some difficulty finding Rockshox that take V-brakes. :twitchy:

To put it simply, yes, you can. You may or may not notice:

-lower handlebar height (slightly more aggressive sitting position)
-increased HT angle, resulting in snappier steering
-reduced ground clearance from lower BB height
-more comfortable turning/leaning--lower BB = lower center of gravity

I'm sure I'm forgetting some things, but those are the basics. I can't tell you how noticeable these changes will be because I have never made suspension travel changes to a bike (that I had already ridden--my bike's travel is 120mm stock & I built my frame up with a 140mm fork), & because how noticeable & whether or not it's desirable depends entirely on the user. I can say from my time on this forum & around MTBs that 100/80mm (or vice versa) fork swaps are not at all uncommon in the XC world.

This is probably because, due to the efficiency/ease-of-use advantages of hydraulic/cable discs (respectively), v-brakes are mostly dead to the MTB world. There's no logical reason to use rim brakes when discs can function properly in any weather & with a bent wheel--two things that most MTBers are quite familiar with.

i believe you just add or remove a spacer to change the travel. Travel can usually be changed in increments of 20 on forks. Usually will be a 80-100mm, 100-120mm or 120-140mm fork.

OK, I appreciate the comments. Is it true Rockshox are easier to service than Suntour forks?

I don't know much about SR Suntour forks....but I love my Rockshox for ease of servicing, and disassembly/assembly!

That's cool. I'm tempted to lean towards Rockshox but I read that SR Suntour XCR is apparently good at absorbing pot holes. I wanted to have like a fun bike to drive around in the streets then take short cuts in the woods with it. Given that people say different forks are suitable for different things, I'm not sure which is more suitable.

i would for sure choose a low end rockshox over the XCR. Rockshox will at least have preload, lockout and rebound. travel wont be adjustable though.

if you want 29er you will have to go disk brake, unless you find a Tora: http://www.blueskycycling.com/produc...-Coil-Fork.htm
