Motion control just means that it will ride nice under your settings until it takes a big hit and a blow off valve opens up for bigger hits. Just how the damping works.

The red rebound at the bottom is how fast the fork comes back up to you, I like mine fast but you can make it slower depending where you ride.

The blue Compression knob is how fast the fork goes through it's travel,you can set this slow or however you like but if you hit something big the motion control should help absorb big hits. I think when you turn this fully the fork locks out?

The black knob on the top will turn and the fork will reduce in travel, drops the front end making it better for climbing or tighter more technical trails.

So here the blue one when fully turned locks the fork, when turned fully the other way allows the fork to take bumps quickly, half way it'll bump up and compress abit less for the same sized bump?

The black on here when turned all the way in one direction will make the fork feel more rigid and only compress alittle and the other way will make it feel more spongy and will compress a lot further?

This one on the bottom is what you were saying about the fork coming back, does that mean that when fully turned clockwise it'll make the fork spring back out to its full length quicker?

And this on the otherside of the bottom I'm guessing is just a screw to keep it together?

Sorry for all the daft questions I just want to know what the bits do before I go changing anything

Pretty much that but the rebound just works on the return of the fork. It should come up pretty fast with it off and feel sluggish with it on. The black cap is just a small cap with an allen key in it.

Rebound is how quick the fork rebounds, so yes, how quick it goes back to full travel (or sag at least). Too slow and it'll bog down in repeated bumps and not have the full travel available to deal with them. Too fast and it'll bounce back and make the bike feel nervous and erratic.

The black dial on top is the U-Turn dial which allows you to alter the travel and length of the fork depending on what you're riding.

I was thinking about going down to Dalby Forest next weekend, however i have never been before and am currently saving up funds for my new bike.

The bike i am currently riding is a Univega Alpina Racelite 500, with Michelin country Gravel tyres, nothing special at all but it serves its purpose for now.

Am i likely to struggle on the harder trails on this bike, i wouldnt say i am a great rider but i do like to push hard (too hard sometimes) or is it worth holding out until end of august early september when i get the new bike (looking like a Genesis Core 10, Ridgeback MX5 or a Carrera Fury) so that i can fully appreciate the trails?

Great, thanks for the help guys. Guess it's just a case of me seeing how I prefer it to be set up now I know what's changing what!

The person in Halfords should really have shown you how to work everything on the bike properly!

Shame but it's a nice bike so hope you can enjoy it

Curiosity got the better of me. Long shocked: Eye to eye is 5mm longer and the stroke is 2.75" instead of 2.5". I took the spring off to check clearance and it's fine.

6.5" travel Heckler.

6thElement · 15 Jul 2010 at 19:10

What did you change from/to? If you increased the length of the shock you've also raised your BB height.

Nice choice of shock though, I'm loving my Vivid 5.1 over my old DHX5.

weescott · 15 Jul 2010 at 19:43

DHX 5.0 @ 215mm eye to eye
Vivid 5.1 @ 222mm eye to eye

I measured the BB height at 14.5" unsprung with fork set @ 160mm. The head angle will also be slightly steeper but I would have to get the correct weight of spring to see how it feels and if it's to my taste.

I'm hearing good things about the Vivid. It would be nice to try it on the Heckler.

If you find somewhere selling cheap Ti springs for them let me know! The 1.5" ID they require makes the springs spendy.

weescott · 15 Jul 2010 at 20:50

The cheapest I have found is £207 for a 3"x450lb. Way more than I spent on the RCS. Best bet is to keep an eye on bike forum classifieds. What size do you need? If I see anything I'll let you know.

6thElement · 15 Jul 2010 at 21:00

I need a 400*2.5"

Not sure if these will ship to the UK but they're the cheapest over here.

I am on the verge of buying a pair of Sixsixone Filter's

Anyone used them with the Wellgo MG1 flats?

Microwave · 16 Jul 2010 at 10:45

Filters are SPD shoes...?

RobotXander · 16 Jul 2010 at 10:46

they convert to SPD, can also be used with flats

Microwave · 16 Jul 2010 at 10:48

For that price wouldn't you be interested in some proper flat-pedal-shoes like Five Tens or Shimano AM40's?

Maybe he would be looking for SPDs in the future?

RobotXander · 16 Jul 2010 at 10:57

It's nice to have the option

Five Ten's seem really expensive....I can get the filters for 55 delivered

Microwave · 16 Jul 2010 at 10:59

Fair enough!

If they're good enough for world cup downhill racers, I'm sure they'll be good for you!

weescott · 16 Jul 2010 at 11:28

I have 661 Filters that I used with MG1's. They work fine. Also used them with Eggbeaters no problem. If you use the shoes with the cleats still in when on flats they can scrape some pedals, although I don't think it was tha bad with the MG1's.
