  1. Chain tension on horizontal dropouts

    1) Pressing with your finger, you should be able to move it up and down a centimeter or so.

    2) Yes this is normal, chain rings and sprockets are never perfectly round or 100% aligned to the center. So be sure to have that cm movement in the tightest spot.

    3) This could definitely mean the chain is too tight, as a very tight chain will put a lot of force on your freehub, and a lot of wear too. It of course can also mean the disc is rubbing a lot, or your bearings are beat.

    For an illustrated example, see https://youtu.be/88tDcVvS7mU?t=252

    Tighten the wheel nuts down very hard to prevent slipping (especially if the frame doesn't have any chain tugs to keep the wheel in position).

    Depending on the way the disc caliper is mounted and the wheel's fore-aft position, you may also need to play around with thin washers underneath the caliper to get the vertical alignment perfect.

    Good luck!

    Legend. Thanks for the time.

    Ps - I replied way before this but just noticed it's not in the thread.  Not sure why.  But anyway, many thanks.

    Regarding 2):

    Screwed-on freewheel or sprocket imply per design a misalignment. This is why splined freewheel of sprocket are superior (in theory at least).

    The same issue is present with bottom bracket.

    But if the difference in chain tension is small, it is fine.

     

    Regarding 3):

    What freewheel are you using? Those with a lot of engagement points (120 or more) have a lot of drag, due to stronger springs.

    They need to be broken in too.

    It's a comas.  Don't think it has that many engagement points but not sure on exact model.

    I've only ever ridden freehubs.  So Freewheels are alien to me.  If I walk the bike, the pedals will move with the roll for a bit and then eventually they will stop and you'll here the clicks of the Freewheel.  Then they'll start moving around again.  Definitely a big difference in chain tightness at different spots too so I'm thinking something is out of line.  How do I know if one is screw on or splined without taking anything aparts?   I'm gonna work on my pads and see if that's aiding the drag too.

    Thanks for the help

  3. Chain tension on horizontal dropouts

    Hi.

    I've purchased a used Marino version of inspired arcade.  Steel frame with horizontal dropouts.  I've never had horizontal dropouts before and have a few questions regarding the chain tension.

    1) how tight should the chain be?

    2) is it normal that depending on where the cranks are in the rotation the chain is different tensions.  Is something bent or out of line?

    3) the wheel stops spinning pretty quickly when I lift the rear end and spin the cranks a few times.  (May be a little disc rub) Is this due to friction in the Freewheel (mounted on hub)?  Or is this another sign of chain being too tight?

    Thanks for any help.  Im just new to this set up style and it's getting in my head a little.  I want full confidence in my ride otherwise I won't ride it well at all.

    Thanks, Adam.

    Cheers dude. I miss trials as it used to be :(

  13. Snapping the bolt on self extracting crankset

    in Trials Chat

    Posted

    I have an Inspired Hex Team 2012 with the truvativ Holzfeller crankset.

    http://www.tartybikes.co.uk/26_inch_trials_bikes/inspired_hex_team_2012/c47p11401.html


    I have been having some left to right (through the bb) movement and spoke to Mark W and said it was a problem with some of these cranksets and the bolt just needed tightening as they require more torque than most. So I torqued it to correct levels and it made no difference. So a few weeks go by and Ive just gone to tighten it again and the bolt just snapped. So now I have a snapped off bolt head (thats loose but wont come out) on the drive side of a self extracting pair of cranks.

    AM I FUGGERED?!!!

  23. GoPro Hero 3 - black or silver?

    in Chit Chat

    Posted

    once the black is set up the remote is ace. On trails i just click to record, put it in my pocket, ride the trail then click to stop at the bottom, and turn it off as batteries aren't great. Obviously you can click the actual camera but its stiff and doesn't always stop combined with the camera moving out of position if you had it set up right. The app, is pretty cool for setting up shots but it annoys me riding trails with the phone in my pocket combined with it using my phone battery.

    the remote alone is abut £70-80 i believe and the silver was only £50 or so cheaper if i remember rightly at the time. I also believe there are a few other benefits which i can't quite recall but one maybe the lense? Id watch youtube videos and go on comparison sites. But in the end i favoured the extra few £'s and its been worth it just for the few times I've needed the remote.

    By the way.....I may sell mine if I get the right price. Used it maybe 8 times (twice on bike and rest just doing time lapse in garden of clouds) never dropped, never dirty, like brand new, totally spotless. Could reattach it to the box (I have all the bits unused) and sell it new probably but I'm no knobby knob knob. Message me if you want a cheaper option to spanking new whilst still basically being new



  25. engineering careers (civil, structural etc)

    in Chit Chat

    Hi, I'm thinking about a new career and stumbled upon a few engineering apprenticeships with Atkins and Jacobs (2 huge global companies). I know a bit about these types of engineering jobs but wanted to know if anyone was actually in these actual jobs and could review what they think of it and if they value it as a career?

    I'm also looking at maintenance with Marriott hotels and lift engineer with Otis. Any insight into these careers would be ace.
