Re: [RBW] Widest tires on green Quickbeam?

[Corwin Zechar]

I have run 38mm Schwalbe Marathon Supreme Duremes under SKS longboards on 
my green Quickbeam. I think they were P45s. Given that the widest tire I am 
aware of fitting on a Quickbeam (also green) was 44mm, this seems correct.

Regards,


Corwin

 A good rule of thumb is max tire = fender -10mm, so 35mm tires for 45mm 
 fenders.

Re: [RBW] Widest tires on green Quickbeam?

[Dave Grossman]

I have 42 Soma Grand Vitesse on currently.  I tried Big Apples once but 
couldn't get them to fit.  I wonder if clearance is much difference between 
colors at all?  I have a pair of Snoqualmies from my recently sold Homer 
that I will try once the weather gets nicer.  In the winter I run 35 
Marathon supremes and fenders and its worked great.  I have Belgiums so I 
suppose I am maxing out width as well with those.

Re: [RBW] Widest tires on green Quickbeam?

[Philip Williamson]

Thanks for reviving this thread! I started at the beginning, and when I saw 
Clayton’s post, I looked at the date. “A… that makes sense.”

You revised your question to ask about max fender widths.
I run 52mm aluminum Velocity Orange Zeppelins over 38mm RH tires on my 2004 
green Quickbeam. The fenders are crimped a bit to pass between the chain 
stays, but not at the seat stays or under the fork. I like the longer 
coverage for the chain in front, and I like to be able to wheel the bike 
around vertically on the rear tire. Setting the rear fender up normally 
shouldn’t need any crimping.

I just changed my 37mm tires to these 38s, and had to flip a mounting bolt 
for more clearance under the 
bridge: https://www.instagram.com/p/ClkhqIjr9oU/?igshid=MWI4MTIyMDE=
The new tires freshen up the bike, and I should probably straighten or 
replace the decade-old stays and add PDW releases: 
 https://www.instagram.com/p/ClKbS02PGoN/?igshid=MWI4MTIyMDE=

I would not put a bigger tire under metal fenders on this bike. Without 
fenders, my biggest tire was a 45mm Smoke  with the side knobs cut off. The 
hassle there isn’t worth the reward to me, and a (~43?) Bruce Gordon 
Rock’n’Road is as big as I’d go in the future.

Re: [RBW] Widest tires on green Quickbeam?

[Bill Lindsay]

Laing indicated that their understanding " is that the PDW tabs are to be 
used on the front wheel if only using on one wheel for safety reasons".

The majority of people who buy those tabs separately use them on the 
front.  Note that all Portland Design Works full metal fender offerings 
include those tabs on Front and Rear.  You are correct that there may be 
less of a safety risk on the rear, but there is still nothing wrong with 
using them in both front and rear.

Re: [RBW] Widest tires on green Quickbeam?

[lconley]

My understanding is that the PDW tabs are to be used on the front wheel if 
only using on one wheel for safety reasons. If the rear wheel locks up, it 
does not throw you over the handle bars like locking up the front wheel 
does.

Re: [RBW] Widest tires on green Quickbeam?

[Minh]

IIRC when i used the P45, i think i was at around 35-37mm on the tires and 
it was tight, fiddly.   i've seen someone with one using the flat wood 
fenders (fancy i know) and that was a little bit easier due to the profile 
of the fenders.

Re: [RBW] Widest tires on green Quickbeam?

[John G]

Wow, what an old thread. :)   So old one of the links points to my long 
dead QB page on att.net.  My QB photos are on Flickr now 
(https://www.flickr.com/photos/14612032@N00/albums/72157711338025308/page1), 
and I'm not even sure my old green one (RIP) is in that album, but I did 
run 44 Mutanoraptors without any issues.  I use mostly 38s now after a 
series of recurrent flats on 32s.

I have run the 38s with old planet bike fenders, but the setup with a three 
speed drivetrain was awkward.  I'm thinking maybe SKS speedrocker 
detachable fenders, which I'm using with good effect with 38s on my 
Specialized Diverge.

 You can measure the chainstay width, inside-2-inside, at the point 
 where the tire passes, then figure howevermany millimeters you're 
 comfortable with for clearance (four is a fine minimum-and the Japanese 
 standard, Times 2 that's 8.). Then do the negative arithmetic, and

Re: [RBW] Widest tires on green Quickbeam?

[Will Millhiser]

My experience too, Eric; thanks.

Perhaps the question I should be asking: what's the widest *fender* that
Quickbeamers reliably run without too much heroics in home-surgery fender
modifications?  --Will

 RBWers -

 I have 35mm tires on my green QB that need replacing. I'm thinking
 about ditching the fenders and going AWAP. Anyone know whether 40mm will
 fit? It certainly looks like I have at least 5mm to spare.

 Thanks
 AJ

Re: [RBW] Widest tires on green Quickbeam?

[Eric Daume]

In my experience (not on a QB) 45mm fenders over 37 or 38mm tires might
work, but it’s very fiddly. A minor bump or misadjustment and something
will rub.

A good rule of thumb is max tire = fender -10mm, so 35mm tires for 45mm
fenders.

Re: [RBW] Widest tires on green Quickbeam?

[Will M]

Hi all.  Revisiting an oldish thread.  What's the biggest tire you 
Quickbeamers are running with SKS P45 longboard feders?  I have an orange 
62cm Quickbeam and wanted to try 700x38mm tires with my P45s.  It's pretty 
clear that the Quickbeam can take 'em.  It's less clear if the P45 
longboards can.  (Websites such as REI 
,
 
etc., say max tire width = 37mm, yet RBW says 
 38mm).  
Thoughts?  Thanks in advance.
