Looks good, but you want to do yourself a favor and only clamp on the seatposts. AL and Carbon can get fragile.

so I scored some 700c fenders at a clearance sale, want to put them on my 700c hybrid commuter... said bike has some rather fat 38c tires on it, Specialized Nimbus... the fenders are barely as wide as the tread... ya think that will provide adequate coverage (I'm assuming most water and road flug comes off the tire center line), or should I pass these on to a bike that has skinnier tires and find something phatter for my hybrid ?

I've go the front mounted, and I see how I can get the rear to clear but havent' done the neccessary modding yet. I'll maybe take a couple pix later today.

Generally, 10mm wider fender than actual tire width is what you're looking for. The problem isn't with stationary clearance, but, once you're moving the fenders will shudder/shake and intermittently touch the shoulders of the tread. I've run a 40mm Nokian 240 under a 45mm SKS fender. They do touch, upon bumps, but, nothing major. However, a 28mm Pasella won't work under a 37mm Velo Orange fender. There are too many variables in actual tire widths and diameters to know, for sure, what'll work.

Based on my experience with Specialized tires, some of their stuff ends up as much as 5mm wider than the sidewall sizing. Of course, we've crossed that bridge, in the past.

fwiw, these are the plastic Planet Bike fenders. I am mounting the fenders about 6-10mm away from the tires, my concern was mostly with how much stuff comes off the sides of the tires vs off the middle. I guess I'll find out when I try them.


edit: and... turns out, they are 45mm wide fenders and with a bit of finessing fit just fine. phew. my primary motivation for fenders is the spring Strawberry Music Festival, when its often quite muddy and mucky. last year, I found myself having to ride really really slowly to keep the mud from coating me. hopefully with these fenders, I'm good to go.

Speaking of mud and such...

Rode 3hrs of off- and on- gravel roads round Culpeper, VA. Unlike the roads I ride around here that are 'gravel' but have been smooshed flat, theirs have gravel as in 'your bike is moving all about under you.'

Lots of fun despite the feeling in my legs from about hour 2 on.

In other words: if you're riding the gravel roads around my house, road tires are fine. If you're riding around Culpeper, bring the knobbies.

Oh, and 50-ish after Crimmus?! :ricky

I've had exceedingly bad luck with my 45mm fenders over 35c tires in sticky mud. They pack up right quick. To the point you have to remove the wheel to fully clean them out.

I thought about maybe doing some kind of tire scraper before it can carry too much mud into the fender, but just decided to not run fenders in such conditions.

I put 45mm PB Hardcore fenders on my GF's 'cross. They work perfect with a 37mm (measured) tire.

However, as "Askel" knows, no fender is worth a shit in mud. We've been on some really nasty stuff, in the rain, and ended up having to ride the grass along the ditch to keep going. The worst part of that is the grass usually grows in clumps, which makes it like riding railroad ties; brutal.

And, most debris is off the center of the tread.

I learnt today that next time I do an almost 140km mtb ride with 1900 metres of climbing, I am not riding 80kms the day before.

Garmin went flat with about 20kms to go.

I was doing it tough at the 50km mark but the boys kept me going.

A few photos off my phone.

We had to climb all the way up there.

I thought so. I was looking at 'em, but, it was beyond my budget.

Way beyond mine too. Especially with the hammerschmit cranks he has on it.

I used to run old aluminum specialized fenders on my 83 stumpjumperer with 26x2.125 tires at this same festival.... and I had those fenders set pretty close to the tires.... yeah, they'd pack up pretty fast if I ran through a bunch of deep mud. I'd stop at a water faucet a couple times a day and blast the worst of the mud out. mostly the ground there is hard pack, just wet on top, so the fenders generally work pretty well and make riding around camp a lot more comfortable.

I do seem to remember way way back when (early/mid 70s?), I used these tire scrapers on my road/touring bikes that were wire loops hanging off the brake bolts and had a little bent plastic tube that ever-so-lightly ran along the top of the tires... they'd knock glass bits and thorns out before they had a chance to go around and get jammed in. hugely cut down on glass and thorn flats in the days before kevlar walled tires. I do wonder if something couldn't be done at the back of the fenders to knock some of the worst of the mud off.

anyways, the Spring festival is Memorial Day Weekend... depending on the weather, if its anything like last spring, I'll be really happy I have fenders again.
