[RBW] 650b tires for 47 cm Roadini

2020-04-22 Thread Erik Wright
I seem to remember reading that the 47 Roadini was designed with bigger 
clearances in mind because tire availability in 650x32-35 is pretty slim, 
whereas 650x38-42 is much easier to find.

[RBW] 650b tires for 47 cm Roadini

2020-04-22 Thread Fullylugged
The Continental Contact Speed is available as 650B x 32.  Blackwall only. 
(English supply)  Hutchison Confriere is also 650B x 32 and has a gray sidewall 
(French sellers).  Grand Bois Cypres 650B x 32 is available with a tan wall.  
(from Japan or from Berthoud).   You can also ask on the 650B list and hunt 
Craigs or Ebay lists. 

Soma B-Line (or Express if you find some around) all are listed as 38 but run 
36 on my bike.  Instead of Nifty Swifty, which has wire bead, you might see if 
you can get Maxy Fasty with fevlar.  It's 33.4 mmm Tan sidewalls.

[RBW] 650b tires for 47 cm Roadini

2020-04-22 Thread Joe Bernard
Eric, does 650B have much larger clearances than the 700C Roadinis? The 50cm 
listed for sale elsewhere on this forum shows Jack Brown 33s without a whole 
lotta room left over, certainly not for 43. I used that same tire on my 53cm 
frame and remember not having a ton of clearance left, either. Side-to-side 
maybe, but not upwards to a Tektro caliper brake.

[RBW] 650b tires for 47 cm Roadini

2020-04-21 Thread Eric G@rs
The clearance according to Vince is 43mm. 38s have plenty of room. I don’t know 
why the geometry charts say otherwise.

[RBW] 650b tires for 47 cm Roadini

2020-04-21 Thread Jim S.
Eric, did her 47 Roadini have clearance for a 38? I must have read somewhere 
that 35 is max. If it fits 38, there are a few more options for sure.

[RBW] 650b tires for 47 cm Roadini

2020-04-21 Thread Eric G@rs
I actually just went through trying to find 35mm tires for my gf’s Roadini. 
Ended up bumping up to 38mm because they were much more readily available. I 
believe Grand Bois Cypres are 32mm, but I couldn’t find those anywhere except 
Japan. Others may be in the know on better options though...

[RBW] 650b tires for 47 cm Roadini

2020-04-21 Thread Jim S.
I see Riv sells the Continental basketball tire at 650b x 32, and that tire 
is surely a good one, but I wonder if there are any other roadish tires 
availble in 650b x 32 - 35 range for that small Roadini.

Panaraer Nifty Swifty's would be perfect, but they don't seem to be 
available anymore.

I know this is a first-world problem, but tan sidewalls look a little 
nicer to me than the all-black basketball tires.
