I fitted my set to my Avanti Vivace 2009 without a problem. I reckon you'd be able to fit these to your bike too.

Don't know about the Feltz35 but on my Roubiax which seems to have a pretty narrow fork, they fit fine. Also note that if they do not fit a narrow fork, they would be very easy to trim a slight notch into so that they would set inside the fork nicely.

Looking at a pic of the Kona PhD I'd say - no they won't fit. This is because one of the three fixing points for the mudguards is via a cable tie around the pivot bolt of the brake assembly on a standard road bike. The cantilever brake set-up on your bike doesn't have the required attachment point. Sweet looking bike though. Try Zefal or SKS mudguards.

Thanks for response. I've actually fitted them and found: as mentioned they really do need a bolt to attach to so if you don't have caliper brakes the best bet is to install a bolt where the brakes would be and then zip tie the mudguard to that. If the frame is not drilled/tapped for a bolt there, then it'll take some creative thinking to attach the mudguards securely - attaching the guard directly to the bridge in the frame probably won't work as it'll twist the guard out of line.

All I can say is that they are very close-fitting. My tyres are 700x23 and I spent a fair amount of time getting them to fit without rubbing. I think you may have problems with 700x38 tyres. Hope this helps.

No the manaufactures state a maximum of 700c x 25mm.

The mudguards are clamped to the brake calliper mounting bolt with a cable tie. You should find that, even if you only have 6 or 7mm clearance between the tyre and frame,they will fit OK. However, a bit of patience may be required to get the perfect fit.

Barney sorry mate cannot help i feel they are to narrow but you will have to contact product manafacturer or call wiggle to see what packaging states

I fitted then to a Giant Defy 4. Needed a little trial and error but once fitted no issues

25s might be OK but you need something to zip-tie the guards (bridge/crown). They are designed to tie to the brake fixing bolt.

Yes. The fitting on the mudguard where it passes the seat-stays is just a moulded slot for a zip-tie. Normally you'd loop the zip-tie around the brake pivot bolt, but you can do the same thing around the bridge in your frame (assuming it's a classic-shape metal frame with a bridge). Otherwise (eg a wishbone style frame) you may need a couple of zip-ties to loop around the wishbone.
Zip-ties are your friend.

Yes they will, but be very careful that they don't rub off your frame anywhere. They wore a hole in my carbon frame in about 3 weeks.

yes
