Not sure on the defy model but we had a marin that took mudguards but **** all fitted between the tyre and brake.
Portland design works do a nice metal guard that stops before the brake and a metal part about 1mm thick goes under the brake then the guard starts again.
Not cheap but seem good quality.
Any info or name for that metal guard mate? Cost isn't a biggie for me as at the moment I seem to be spending £30-40 every 4-6 months on a set of guards...
Clearance on my Defy1 is less than 10mm from tyre to caliper 'tops'.
The Raceblade Longs I'm using are removeable from a metal L bracket which fits in caliper/bridge bolts, they're around 1.5mm thick and can be bent to shape the clearance. It works well but it means the guards have quite a bit of vertical 'bounce' as some of the L brackets have to be quite long (you're given several different lengths).
Defy is a total pain in the arse for guards. I think only the giant own brand and cruds will fit. And I couldn't get either to fit on 25mm tyres so I have to run 23s. It's the clearance under the brakes - it's crap.
Cruds are too close for 25mm's (I found they're physically not wide enough) but they fitted ok on 23mm. Giants own brand fit but are damn tight on 25mm (less than 2mm lateral movement causes rub), they're also noisy as hell and 'clatter' over any bump in the road.
I've heard SKS Chromo 35's fit with some adjustment/trimming.
SKS Raceblade Longs fit fine (see above about brackets) but they do move around, rub a little (less than the Giants and Cruds) and make some noise. Also clearances are so tight that eventually you'll wear through the 'tabs' on the guards which hold them into the brake brackets. Easily fixed with a cable tie but then they're not easily removeable.
I've had better lateral clearance since trimming some of my stays (by around 14mm) and fitting them to my mounting points rather than on the QR's. Less noise too as they bounce less off my tyres on the bigger bumps. I added some washers for some extra width and the bolts I used (from my giant guards) were too long and didn't fancy trying to cut them...
I agree with the point about people voting for what they have. It's just a shame that so many people ride on turd tyres.
Everyone in my group uses Gator's in the winter. They're mad about them and are always trying to get me to change ober, personally I've seen so much negative that I steer well clear.
To be honest, I can't fault the tyres that my bike came with. Continental Ultrasports. 3.2k miles, and just had my first puncture :0
I think the main thing is that Halfords and several big bike shops use them and recommend them, I guess they try to use Continental's and the skaters are the only 'all weather' one they do...?
Then you get these guys coming in asking for a tyre 'for all weathers' - yet they only ride it on good roads in normal weather and not the horrific wet winters like we do...!
