Re: rear wheel alignment

Check the conical spring on the QR isn't trapped in the dropout on one side... Turn the bike upside down with the wheel in place and have a look.

Re: Bike specific security fasteners?

I've just had an idea...

I'm thinking of taking an old 5mm allen key, grinding the working end a little just so it's a 'unique' shape, then holding the allen key in the screw head whilst packing some quick steel (an epoxy resin like miliput) then withdrawing the key as the putty is hardening. Once the putty is hardened properly I should have a homemade security screw! Just better not lose the allen key.

I'll report back after I've tried this.

Bike specific security fasteners?

Hi all,

Yesterday some thieving scrotebag made off with the bars and stem (with grips, shifters and brake levers) from my girlfriends bike and I'm about to embark on sourcing repleacements.

I know where I can by security fasteners but does anyone know of anyone that does bike specific security fasteners? I'd also be interested to hear any hints or tips for keeping the new bits on the bike this time!

Thanks
Craig

Re: Weylandt death

RIP Wouter. When I read the article I had a massive knot in my stomach, this sort of thing just shouldn't happen to anyone, let alone a pro with full, immediate medical assisstance.

I also just read an article elsewhere (a non-cycling publication) stating that his 'pedal locked'... can anyone shed any light on the cause of the crash?

Craig

EDIT - just read about how it happened on wikipedia. Feel a bit sick now.

Anyone have a good letter template for complaining?

Hi,

I've the need to write to a haulage company to complain about one of their drivers scaring the absolute bejeezuz out of me by leaving very little space when passing... Does anyone have a tried and tested template for such a letter that I could pinch (I've had a search but couldn't find anything). I have it all on headcam and will send a copy of the video with the letter (and email). Screenshot from the video below... he was going a good 30mph faster than me!

Re: Longer travel front mech?

Ah of course it's 2.5mm at each end... thanks to not engaging brain before typing I subtracted 113 from 118 and got 3 :oops: It's Friday after all

Anyhoo the problem is now solved... I've removed the BB to check it's length (definitely 113mm), refitted it and the chainset then removed the mech, cleaned, lubed and refitted it and miraculously it now moves far enough out to shift properly onto the big ring! I've rechecked the chainline now it's working and it's the same as before. Must have been general road crud and neglect that caused it to seize a little.

Thanks for the help guys... I'll most likely be back for more soon enough!

Ah... I'm measuring from centre of seat tube to middle ring. The middle does look to be slightly closer to the big ring than the small, so if that's the case then my chainline is closer to 50mm than I thought. I suppose I'll have to measure the distance from the seat tube to the big ring and then the distance to the small ring, split the difference and add it to the small ring distance to get my chainline accurately the 'Shimano' way

JEJV wrote:3mm out might suggest that you have a 118mm BB, or the measurement is wrong, or the frame is strangely skewed.


A 118mm spindle would only increase the chainline by 1.5mm over a 113mm spindle (1.5mm longer at each end), so if my chainline is actually closer to 50mm than 53mm (51.5?) then this could be the problem... I'll have to whip it out to check (ooh err!).

Cheers guys

Re: Longer travel front mech?

Thanks for the replies guys...

I think a BB with a shorter spindle is the order of the day then. My chainline at the moment is about 53mm. Shimano apparently think that a 113mm UN-26 BB with a M410 chainset will give a chainline of 50mm (which the mech works with), but there's no way I'm getting the chainset any further onto that spindle.

A 107 mm BB shall be ordered!

Thanks again.

Longer travel front mech?

Hi Everyone...first time poster here! Apologies if something similar has been posted before, I've only done a cursory search as I'm at work :lol:

My current technical conundrum is that my front mech seems not to have enough travel... It physically doesn't move far enough out to shift onto the big ring. I'm using a friction shifter at the moment and there is plenty of cable left to pull when the mech reaches it's travel limit (I've completely removed the H limit screw just to make sure) and there is no possible way to get the chainset any further onto the BB spindle (which theorecically would cure the problem as there is plenty of spare 'inwards'travel when on the little ring).

Does anyone know of a front mech with a better range of travel? Or is it a case of fitting a BB with a shorter spindle (there's plenty of room between chainrings and chainstay). Any other options greatly appreciated!

Set up at the moment:

Shimano Tourney 3sp friction shifter
Shimano Deore M530 front mech
Shimano Alivio M410 chainset (22,32,42)
Shimano UN-26 BB (113x68mm)

Many thanks
Craig
