Re: Which canti's of these are best...

I converted my Cyclocross race bike to Tektro Mini V's having tried a lot of different cantis (Oryx, 520's, Frogg Legs) because they cost the same as the Travel Agents you need for full V brakes. They stop really well, especially in the wet, but you need to use an inline barrel adjuster because rim ...

Re: KOPs how do u measure?

@Brucey KOPS is incorrect simply because your thigh isn't my thigh, your shin isn't my shin, your crank isn't my crank, your tourer isn't my TT bike. That is not 'slagging it off'. Those are the parameters that KOPS does not take into account that affect saddle fore/aft position. And that assumes th...

Re: KOPs how do u measure?

Hi, How will we know when we get it right :?: You won't - but you will know when you've got it wrong because something will probably hurt - that is true whatever method you used to get a set up. I've never used KOPS - I set the seat height based on slightly less than full extension when the pedal i...

Re: KOPs how do u measure?

given the almost infinite variation in the human form, and certainly variations in thigh, shin , leg and torsos, why would this ever be a meaningful measurement?

Re: Turn my track bike into a commuter

really have to question whether this is worth it? If the fork isn't drilled then that would rule out a conversion for me. Unless you can borrow a wheelset and tyres and brakes to try this could be an expensive failed experiment. With Langsters, Touches etc going for around £250 on eBay then that wou...

Re: good factory wheels - racing/audax

I have a pair of Fulcrum 3's and a pair of 5's. The 3's are excellent, but I believe the spokes are a special item, mainly because there is no hole in the rim where a conventional spoke would enter. The surface is completely smooth. No rim tape required therefore, but I can't see how the spokes are ...

Re: Fitting Hub Cartridge Bearings

I just use a coach bolt and some suitably sized washers.

Re: Rain on glasses

if they are standard daily disposable soft lenses, then you can clean them (as you used to do before they became disposable!) I only wear lenses when racing so once or twice a week - quick pop into the All In One solution and use them again next time. (Generally change them about every month to avoi...

Re: Traditional cantis versus mini V brakes

I've just gone to this set up on my cyclocross bike after various attempts at getting cantis to work well. The key is to fit an inline barrel adjuster so you can get enough slack to release the noodle. A spoke key will have to become part of your toolkit. But they definitely stop, no juddering. Not ...

Re: Recommendation for bike Lights

"Having done the whole lead acid, NiCad, NiMh battery saga" +1 and led torches, Magicshine clone, various halogen and LED solutions the most reliable solution for a 3 hour commute in darkness is my Shimano dynamo and Busch & Muller 60lux IQ Cyo. The beam spread is great for road riding...

Re: Hub dynamos

I have heard that these sorts of lights can muck up wired cycle computers which is a classic sign of high speed voltage switching. I think you mean "wireless" cycle computers - wired should be fine. Heart Rate straps are usually wireless however. I just bought the Busch & Muller Cyo b...

Re: Shimano triple problem with new Stronglight rings

Problem solved but not really explained! I did as 531Colin suggested and the mech would not pull across to the big ring, even the H stop screw hanging out. Having calmed down from last night I realise this can only be due to the crank not being seated against the BB properly (despite me removing the...

Re: Shimano triple problem with new Stronglight rings

It's a bottom pull mech. Cable has been on and off more times than I care to recall. And the barrel adjuster reset each time to give some further adjustment. It's not a cable tension problem IMHO. Will try 531 Colin's suggestion of unscrewing the limit screws and pulling the cable manually whilst tu...

Shimano triple problem with new Stronglight rings

Last night I changed the chain rings on my commuter for 3 brand new Stronglight (Dural) ones. They are not ramped or pinned in any way and I can’t get the front mech to shift properly at all. It’s a newish front mech (Sora 9 spd <3 months old) , same crank as before – the rings are slightly larger (...
