Re: [RBW] Re: Some 650b conversion pics

Jim, looks great! Fantastic color on that frame BTW. How is what I
presume to be a relatively low BB height working out? I've played
around with doing just that on my Riv Road, but am not sure I can
quite fit Hetres in there.

Re: [RBW] Re: Some 650b conversion pics

[Jim Bronson]

I shortened the cranks from 180 to 170 to compensate for the low BB height,
plus the 180s were hurting my knees.  I ride 175s on my other bikes and it
feels good.  I don't think going one more step down to 170s is hopefully
going to cause any problems.  It seems fine just riding around.  It does
feel like I need to put the seat higher now, I'll work on that tomorrow
afternoon.

Speaking of riding around, shifting is awesome now with my mixed drivetrain
with the Shimano bar-ends.  It shifted like crap with the Campy bar-ends
and the Shimano cassette, but now that has been successfully remedied with
Shimano bar-ends.  I've been told the 9 speed spacing is the same but who
knows.  Oh well works great now.  And I have a friction option now too that
I didn't have before.

My cream longboards showed up about 5:45 this evening but my wife and I had
a social engagement to go to.  I just finished watching the installation
video Riv posted.  I don't have a kickstand plate though, and I don't think
my chainstay bridge is threaded.  I suppose I could drill it out and tap
some threads.  Or just use zip ties.  Well anyway I hope to have it done by
Saturday morning so I can go ride in the rain :-) and cold :-(

Get crackin' on that project, running out of time! Hopefully the 170s
will be fine. Are you going to put Hetres on?

Re: [RBW] Re: Some 650b conversion pics

[Tim Gavin]

That's a fun and quick fender stay method, Tom.

My Riv Road has no plate, and only a small drain hole on the chainstay
bridge.  I used a rubber covered P-clamp and a long bolt to span the gap
(you filled the gap with a cork, nice).  The long bolt allowed me to fine
tune the fender arc.

I can get  a picture later if you want it, Jim.  Very nice bike.  The cream
longboards look fantastic with the Riv head tube and decals.

Re: [RBW] Re: Some 650b conversion pics

[Patrick Moore]

Isn't the sole point of this conversion exercise that you can use *fatter*
tires, and significantly fatter tires? So, while you might lose some bb
height, you won't lose nearly the whole 19 mm ?

A 622X23 mm tire is about 26 1/2" in diameter. A 559 X 1" tire is about 24"
in diameter. A 559X35 mm tire is about 25" in diameter. A 559 X 50 tire is
about 26" in diameter. I cite these only as being directly or indirectly
relevant sizes known to me by experience.

Thus, if you went from a 700C X 25 to a 650B X 42, which seems common,
wouldn't you gain back some 10 to 15 mm?

Re: [RBW] Re: Some 650b conversion pics

[Jim Cloud]

The early models of the Rivendell Road were designed for a 700x28c tire 
size,  I don't believe you would be able to fit a 650x42b size tire between 
the chainstays of those particular bikes (I also own an original 1996 model 
of the Road Standard).  

I don't, however, see a post by the OP that indicates what is the tire size 
that he fitted to his bike.  The tread pattern, however, looks like one 
used by RIvendell.  The only tire that Rivendell currently sells in the 
650b size that's a Rivendell design is the Maxy Fasty which is a 650Bx33.5 
size.

Don't know about a 42mm tire, but the waterford-era Riv Road is on the 
list of known-to-work conversions on the freewebs 650B site:

Re: [RBW] Re: Some 650b conversion pics

[Jim Bronson]

My bike is an older custom that had 700x28 on it when I got it used in
2005/6.  Probably designed around 700x28 for the original owner.  I had
been running Grand Bois Cypress 700x32 for a while but with minimal brake
clearance.

I took it on a post-conversion 130 mile shakedown ride yesterday and
handling seems to be unaltered.  I even pedaled around a u-turn on a narrow
road and didn't suffer a pedal strike, which I had been worried about.

I was running Nifty Swifties which are labeled as 650b x "32.8 mm or so".
I also installed P45 cream long boards that I got from Rivendell.  Those
were not depicted in the images in the thread starter.  It was wonderful to
have the fenders as temperatures hovered in the mid to upper 30s with
intermittent drizzle all day.  Not exactly chamber of commerce weather for
Central Texas.

For me, running fatter tires with fenders is the whole reason I did the
conversion in the first place.  So far I am pretty happy with it.  I will
try wider tires still when I get around to it.  I have some Pacenti
Pari-motos waiting in the garage,  650b x 38.  I'm pretty sure those and
the 42s also will fit.  I may have cut the fender stays a bit short but I'm
sure spare parts are available.

Re: [RBW] Re: Some 650b conversion pics

[Jim Bronson]

I have the Nifty Swifty installed in the pics.  They are very inexpensive,
and I wanted something to try out 650b with, without having to invest $120
or more in tires.  I got the Nifty Swifty tires for $26 each from
ebikestop.com.

The Maxy Fasty is the same as the Nifty Swifty but without the Nifty
Swifty's extra flat protection belt.

How wide is your Road Standard's chain stay bridge?  Would be interesting
to compare.  Mine is not very wide.  Barely enough to accommodate the
fender.

Re: [RBW] Re: Some 650b conversion pics

[Tim Gavin]

The Waterford era ('94-97ish) Riv Road Standards do work for 650b
conversion, but they're not ideal.  Mine is an early '97, with a max of
700x28x tires (less than 2mm of clearance above Ruffy Tuffy's)

I converted mine from 700x28c to 650x38b, which dropped the bike 9mm (lost
19mm of rim, gained back 10mm of tire).  I have scraped the outside edge of
the pedal once or twice, but I usually drag a heel before I drag a pedal.
 A rare and avoidable occurrence, either way.

650x38b seems to be the maximum tire on this frame, as both fork blades and
chainstays are too tight for 42mm Hetres, as far as I can see (currently
running 38mm Lierre).

This conversion makes room for P45 Longboard fenders, but the front tip of
the rear fender is squeezed a bit in the chainstays.  Also, the long
mudflap becomes a big leaf scoop; I take it off on non-rainy days.  I'll
probably add the shorty mudflap to my next Riv order.

Re: [RBW] Re: Some 650b conversion pics

[Jim Cloud]

As the site that you reference indicates, Rivendells with a 8 cm (80mm) 
drop and 325mm radius tires only have a bottom bracket clearance of 9 1/2 " 
- "which is very low for anything longer than probably 155mm cranks":.

Tim's post indicates that his bike doesn't have clearance for tires larger 
than 650Bx38mm, this is probably the same for my bike and most other early 
Rivendell Road Standard bikes with a 80mm drop bottom bracket.  In my 
opinion, the success of a 650B conversion with these bikes would be 
conditional on the length of the crank arms (and choice of tires).  
Anything more than 170mm is probably not very advisable, and perhaps 165mm 
would be a better option.  The largest radius tires that will fit between 
the chainstays ( approximately 38mm) would also be more practical.

Most of the 700c conversions to 650B are bikes that had bottom bracket 
drops of 65mm-70mm.  Obviously, when Grant originally designed the 
Waterford era Rivendell Road Standards he was biased to a lower bottom 
bracket which he preferred for handling.  The bikes were never envisioned 
for a 650B conversion (obviously, since the French 650B tire was almost 
defunct in that period).  I still think a Rivendell Road Standard 
conversion is possible and may provide satisfaction to the owner, but 
clearance of the pedals may be an issue for care while cycling (pedaling 
through a tight curve is probably not advisable).

Re: [RBW] Re: Some 650b conversion pics

[Jim Bronson]

The more you describe it, the more I think that my custom is closest in
geometry to those early Riv Road Standards.  Being the 2nd owner, I don't
know much about the history, but the gist of it was that he was probably
too tall for an off the shelf Road Standard at 6'5".  I'm a little taller
at 6'7" but I think the frame works well for me for the most part.

At any rate I had the same issues with the Longboards that you mentioned,
the front mudflap tended to catch and drag and the front tip of the rear
fender is a bit squeezed in the chainstays.

Although, I did mount the brake tab behind the fork, which I think
magnified the mudflap dragging issues.  I will be moving it to the front of
the fork the next time the bike is in the stand.  Hopefully that will help
some.  If not I might trim it up a bit.

 So you took a 700c wheeled bike & converted to 650b?  Ignoring the
 tires for the moment, doesn't that lower everything 19 mm?  What effect
 does it have on the handling?  I've read about picking a wheel size &
 designing a bike around that, so this seems a radical change.  OTH, people
 have been converting 80s era bikes to 650 with good result.  How did you
 know this was going to work?

Re: [RBW] Re: Some 650b conversion pics

[Jim Bronson]

I can attest that so far it's working fine with 170 cranks, and without
putting on the 38mm tires I bought.  I didn't scrape on a uturn on a narrow
road while pedaling, and I would never pedal on a corner with a lot of bike
lean in it.  So I think it's fine so long as you're mindful of what you're
doing, and clearly anyone who would convert their bike to 650b is probably
very mindful of what they're doing.

A 650b conversion not something that you could just go down to your local
LBS and ask them to do without getting a few blank stares.  Well if they're
not of the Rivendell mindset anyway ;)

Re: [RBW] Re: Some 650b conversion pics

[Tim Gavin]

I also moved the brake tab to the back of the fork with a Sheldon's nut,
and it exacerbated the low mudflap issue.  It still doesn't drag on clean
pavement, but it makes me "Mr. Plow" in loose leaves.

Like I said, I just take the flap off during leaf season.  It comes off in
seconds; just push the central pin out with the smallest hex on your multi
tool.  Stows in my luggage, so I can put it on quick if rain breaks out.

That's true, but I get blank stares with all my bikes at the LBS.  They're
all lugged steel, and all have my own goofy custom touches.

However, I love the simplicity of the conversion.  With the fenders off, I
can swap wheels and brake calipers in 10 minutes or so, and go back to 700c
any time.  I have a 7 speed Phil FW hub on my 700c wheels, and a 9 speed
cassette on my 650b wheelset.  Silver friction shifters don't care.

Re: [RBW] Re: Some 650b conversion pics

[Tim Gavin]

Gen 1 Riv Roads have 80mm of drop, for a BB height of 260mm (according to
the early catalog)
http://www.campyonly.com/images/mystuff/2006/rivendell_road/rivendell_catalog_3.pdf

That BB height is measured on 700x25c tires.  Converting to 650x38 equals a
frame drop of 6mm (19mm smaller wheel radius, 13mm larger tire), for a BB
height of 254mm.  Not a huge difference.

But in the same article, Grant already warns about pedal clearance in
corners.  Lower the bike by 6mm and you should be very conscious of pedal
scrapes.  Gaining back 5mm of that clearance with shorter cranks isn't a
bad idea.

I find the advantages of the 650b conversion to be huge (cushy tires and
fender clearance), and the risk of pedal scrapes to be a minimal
disadvantage.  ATMO.

Re: [RBW] Re: Some 650b conversion pics

[Bill Lindsay]

"I find the advantages of the 650b conversion to be huge (cushy tires and 
fender clearance), and the risk of pedal scrapes to be a minimal 
disadvantage.  ATMO."

Also, just in case you want or need corroboration from somebody 
not-named-Grant, check Bicycle Quarterly when they do the review of the 
Lyon L'Avecaise.  They loved it, and it had a BB height lower than even 
Grant's "safe minimum" of 260mm, and that is a purpose-built 650B race 
bike.  I don't have it in front of me, so I forget if it was 256 or 254mm, 
but it's in the 250s and they LOVED it.  

Disclosure:  Even though Jan loved that bike and even though that bike had 
a low BB, Jan pretty emphatically states elsewhere that BB height has 
almost nothing to do with ride quality.  Conventional wisdom is a lower BB 
height gives more stability.  Jan pretty convincingly debunks that.  Lower 
BB height doesn't do much of anything.  It's neutral.  You don't *need* a 
low BB, and you don't necessarily need to be scared of a low BB.  Maybe 
250mm should be the new safe minimum for conversions?
