Another fork thread

Similar to the poster in the spa crash damage thread, I have been looking for a new fork with mudguard clearance in 1 1/8 dimensions, and long drop brakes. There doesn't appear to be a huge amount of off the shelf choice. In full Carbon there is the Whisky 7RD, nice but pricey, or the Columbus "...

Re: front wheel flexes whilst climbing? cause

Currently Shimano BR650 deep drop brake. Clearance, with guards is "interesting". I can run 28mm GP4 seasons no problem, however 28mm GP4000II, on the other hand need a little modification of the mudguard to fit. Rear is also 28mm, but I could probably squeeze a 30mm in there, depending on...

Re: front wheel flexes whilst climbing? cause

Update, I moved the SP hub onto my Fixed with the Steel fork, almost no movement. I moved the USE hub to my Rourke with the carbon fork, massive amount of movement.- This has no movement on the steel fork. I put the hand build font wheel (Non dynamo) onto the carbon fork,(28 hole) not as bad movemen...

Re: Can anyone recommend to me a breathable, brightly coloured & reflective waterproof jacket?

I have a showers pass elite jacket. Very good but not perfect. Vents work great. I do end up sweating in it if on a long ride. As an aside, the US company were great when I managed to put a couple of holes in the jacket, sending free of charge a large piece of material that I could glue on to fix it...

Re: front wheel flexes whilst climbing? cause

Yes my issue is that I have had to back the brake off a lot, which happened previously and is now at 4-5mm. The brakes I have are Campag Athena 11speed with a BR650 front brake, as I didn't like the way that the tekros that I had on previously used to bend. I will be changing over the wheels today a...

Re: front wheel flexes whilst climbing? cause

Ok quick update, I had my wheel rebuilt with another SP hub, it was too complicated for anything else, this solved the problem, however, after the last long ride that I did, I noticed on a subsequent short outing that the wheel was again rubbing on the brake blocks when I was climbing. The communica...

Re: Checking gpx routes

Hi Mick, to explain myself better, the way the route should be planned for an Audax is that the minimum distance between the controls in the correct order, will be the minimum distance for that ride so for a 200km event, the GPX file may be 215km but the minimum distance possible measured between th...

Re: Checking gpx routes

Hi Mick, I once spent a 200 audax continually overtaking the same rider, in the end I worked it out. She had much better "control" discipline than I did :lol: :lol: The route for an organised audax is never mandatory, you just have to hit all the controls, so those riders may have been tal...

Re: Custom Bike Build - Educate Me Please

Hi Witterings Generally speaking a custom bike would probably be referring to a custom made to measure frame. Most commonly in steel, any type, probably followed by titanium. A few people can do custom carbon frames. You also spec everything else on the bike, including the paint. Cost of the frame.....

Re: Campag Athena groupset changing the rear cassette and rear derailleur to a wider block

Hi Pete, I heard this before, my worry is the pull on the Athena is not quite linear ( I may have got this wrong) as the spacers between the sprockets are not the same width.
What chain do you run? Campag or Shimano?
