[RBW] Re: Tires/Wheels for new Sam Hillborne
The sks fenders with the 40s were a little bit of a tough fit but I was able to get decent clearance. As I mentioned, I had to elongate the mounting hole almost down to the fender. I also had to bend it over like they showed on one of the Riv videos. That was the only way I could slam them flush with the underside of the fork crown. Worked great. I'd try to get a picture but I'm not running fenders now and the Mondials aren't mounted. John -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.

[RBW] Re: Tires/Wheels for new Sam Hillborne
unless I was considering a long trip, through puncturous land, i would probably opt for a different tire. There are some really nice ones in the 40mm range that will make your sam feel excellent. I also am of the belief that most rivs should ever wear a tire less than 40mm. but that's just me. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.

I am looking to get fenders for my Sam. I am running 650bx42 Gran Bois tires. I am partial to the hammered Honjo's 650bx58 but have a hard time imagining they will fit the modern Sam (with the long-reach caliper brakes instead of the trusty ol' canti's).

Re: [RBW] Re: Tires/Wheels for new Sam Hillborne
double-check with riv but many schwalbes come in undersize relative to the label, my 35's actually measure 33, i think the 40/42 supremes come in around 37. if you have the space (and on my hillborne with 48m steel fenders i can handle a 37) then i suggest as much tire as possible.

Re: [RBW] Re: Tires/Wheels for new Sam Hillborne
The reasons to pick the 40s are: more comfy, more durable, more traction, more safety, no slower The reasons to pick the 35s are: you are a gram-counter and want the lighter ones or you are forced to 35s because the 40s won't fit On Wednesday, August 7, 2013 12:29:15 PM UTC-7, Mark Taintor wrote: Thanks for all your thoughts everyone.

[RBW] Re: Tires/Wheels for new Sam Hillborne
Two concerns: Tire height and tire width. *Tire Width:* RBW says that the P45 Longboard fits tires up to 45m wide. *Tire Height:* You have to think about the *height* of the tire and being able to have enough clearance to sandwich the fender and brake arms between the top of the tire and bottom of the fork crown, and will there be enough clearance for the brake arms to move without them smushing down on the fender. Now, running a 35 tire should be able to get you more space vertically between the top of the tire and the bottom of fork crown, if a 40 doesn't work. So you could mount the fender further away from the brake arms if more space is needed so they do not contact the fender. That is the only benefit I can think of to having a narrower tire. Other than a narrower tire looks cool. For instance, both my 52 Sam and 55 Bleriot have their P45 Longboard fenders mounted as high as they will go under the fork crowns in order to accommodate my 650b x 42mm Marathons (Sam) and 650bx42mm Hetre tires (on Bleriot) with my Tektro R559 brake calipers on both bikes. I have about 1.5 mm of space between the bottom of Tektro brake arm and the fender on the Sam with marathon. The space grows as the brakes are applied. It is tight, but works great. Brakes do not touch fenders, and their is plenty of clearance for the tires. About 3mm of clearance between the Bleriot Tektro R559 brakes and the fender with Hetres. Plenty-o-space. (BTW, the Marathons are called 42mm and the Hetres are called 42mm width tires by their manufacturers, but both measure 40.5mm width on synergy rims at 55 psi). -- You received this message because you are subscribed to the Google Groups RBW Owners Bunch group.

Re: [RBW] Re: Tires/Wheels for new Sam Hillborne
You can fit 650B wheels on any 700C bike. The question is which brakes to use. The Sam uses sidepull brakes. Ask Riv what the reach is for a 650B rim on a 56 Sam. Silver sidepulls reach to 75mm; Dia Compe/Weinmann centerpulls reach to 78mm. If the reach is more than that, then you may be out of luck. Well, there are BMX sidepulls that reach further, but I don't know how effective they are on larger, 650B rims. If your Sam uses cantilever brakes, then I think you're stuck with the wheel size they're mounted for. The question is, what would you gain with 650B? You can already fit 45mm tires on 700C rims on the Sam. Do you want more float than that? If you do, then go for it. I converted my Riv Road to 650B and love it. But I was limited to 28mm tires on 700C rims, and much prefer the 38mm Lierres. I may even try some light knobbies for gravel (27.5er MTB tires are getting more available). And it's pretty easy to swap back and forth between my 700C and 650B wheels; just swap brake calipers along with the wheels.

Re: [RBW] Re: Tires/Wheels for new Sam Hillborne
You can fit 650b wheels on any 700c bike, but some 700c bikes won't fit 650b tires. This isn't an issue for Mark's Sam, but it's worth noting for 650b conversions in general. If your frame has tight clearances with 25mm 700c tires, currently-available 650b tires will be very tight. If 23mm 700c tires are tight, you're likely SOL without frame modification. AFAIK there are no 650b tires narrower than 32mm currently available; GB Cypres and Hutchinson Confrérie des 650 are the narrowest at 32-33mm. The only very slightly narrower tire sometimes available is the discontinued Michelin Megamium, 31-32mm. I have two 650b conversions in-house with less than 2mm tire clearance at the chainstays, a '96 Waterford 1200 with Megamiums and a '76 Mooney with Confreries. Both are pretty tight with 25mm 700c tires. They have vertical drops so no chance of wheel slippage, and I'm stupid enough to ride both---on decent roads, not too far from home. The Mooney is Reynolds 531 but has great paint, so I'm not ready to have the chainstays crimped. The W'ford also has great paint, but beyond that it's built with Reynolds 753, not a great candidate for crimping. Nothing wider than the Megamiums will fit in the W'ford, so when either of those tires dies it's back to 700c. The question is most definitely what would you gain with 650b? The conversion ideal is using a 650b tire with enough volume to both improve the ride and not drastically change handling. On these two bikes I'd rather have 31-32mm 650b rubber and tight clearances than 25mm 700c rubber and tight clearances. I would love to see a true 30mm supple 650b tire to help give better road manners to crit bikes... Paul Brodek Hillsdale, NJ USA Quoting Tim Gavin : You can fit 650B wheels on any 700C bike.

Looking on the Riv website at the page for the Betty Foy, it says that the Betty and the Sam can take the same volume tires. The Betty mostly uses 650B wheels. As of now I'm planning on 700c wheels, but am intrigued with 650B. Thoughts? Thanks,Mark -- You received this message because you are subscribed to the Google Groups RBW Owners Bunch group.

Re: [RBW] Re: Tires/Wheels for new Sam Hillborne
You can not run 650B wheels on a 700C Sam Hillborne. The reasons are threefold 1. Reach. The brake clearance on a 700C Hillborne is dialed for a long reach sidepull brake. A 650B would require ~20mm more reach than an already long reach brake. There are no good 90mm reach brake calipers. 2. Drop. Grant already dialed the frame design of the Hillborne for 700xfat tires. Among those things that are dialed is the BB drop. Run smaller diameter wheels, and your already low BB height will be in true pedal-scraping territory. Virtually all recent 700c Rivendells are lousy candidates for 650B conversion for that reason. The roadier Riv models of several years ago are good candidates because they were designed for 700xskinny and have less drop. 3. Geo. Grant designed the stability and handling for the 700c wheel. He does things differently for 650B wheels. If you were dead-set on running 650B wheels and wanted the price and sizing of a 56 Sam, you'd switch to a 55 Betty Foy and run 650B wheels. It would work great. On Wednesday, August 7, 2013 7:18:11 AM UTC-7, Paul Brodek wrote: You can fit 650b wheels on any 700c bike, but some 700c bikes won't fit 650b tires. This isn't an issue for Mark's Sam, but it's worth noting for 650b conversions in general. If your frame has tight clearances with 25mm 700c tires, currently-available 650b tires will be very tight. If 23mm 700c tires are tight, you're likely SOL without frame modification. AFAIK there are no 650b tires narrower than 32mm currently available; GB Cypres and Hutchinson Confrérie des 650 are the narrowest at 32-33mm. The only very slightly narrower tire sometimes available is the discontinued Michelin Megamium, 31-32mm. I have two 650b conversions in-house with less than 2mm tire clearance at the chainstays, a '96 Waterford 1200 with Megamiums and a '76 Mooney with Confreries. Both are pretty tight with 25mm 700c tires. They have vertical drops so no chance of wheel slippage, and I'm stupid enough to ride both---on decent roads, not too far from home. The Mooney is Reynolds 531 but has great paint, so I'm not ready to have the chainstays crimped. The W'ford also has great paint, but beyond that it's built with Reynolds 753, not a great candidate for crimping. Nothing wider than the Megamiums will fit in the W'ford, so when either of those tires dies it's back to 700c. The question is most definitely what would you gain with 650b? The conversion ideal is using a 650b tire with enough volume to both improve the ride and not drastically change handling. On these two bikes I'd rather have 31-32mm 650b rubber and tight clearances than 25mm 700c rubber and tight clearances. I would love to see a true 30mm supple 650b tire to help give better road manners to crit bikes... Paul Brodek Hillsdale, NJ USA Quoting Tim Gavin : You can fit 650B wheels on any 700C bike. The question is which brakes to useThe question is, what would you gain with 650B? You can already fit 45mm tires on 700C rims on the Sam. Do you want more float than that? If you do, then go for it... Tim On Wed, Aug 7, 2013 at 6:20 AM, Mitch Browne mitch@gmail.comjavascript: wrote: I've ridden Supreme 40's under my Atlantis Longboards daily for almost two years now.

Re: [RBW] Re: Tires/Wheels for new Sam Hillborne
Good one, Steve, and excellent point. If you decide that you don't mind the fact that you can't equip your bike with brakes in 1) then you could work around the too low BB in 2) by running too short cranks. Best of all, run no cranks or BB at all, since you'll probably want your feet on the ground anyway to provide Fred Flintstone braking. You could make it into an adult sized skuut bike! That would be fun! On Wednesday, August 7, 2013 10:32:36 AM UTC-7, Steve Palincsar wrote: On 08/07/2013 12:53 PM, William wrote: You can not run 650B wheels on a 700C Sam Hillborne.
