Which rims for Big Apple?
Anyone with experience of Scwalbe's Big Apple tyre?
1.Is it true that the Big Apple is a good substitute for a suspension fork and a suspended setpost? 2. What size tyre? What size rim? What make rim? 3. What size rim would in your opinion be better? 4. Anyone else with an opinion of what width and which make of rim would be best for Big Apple in 50mm and 60mm widths? **** For the record, according to Schwalbe's FAQ, E|RTRO says you can fit tyres up to 62mm on 21mm rims. And you can even fit them on 17 to 19mm rims, if you do not inflate above certain limits )eg 45psi for a 60mm tyre). Andre Jute http://members.lycos.co.uk/fiultra/B...20CYCLING.html |

Mr. Colina, Mr. Jute is on line 1. "Yep. There's nothing else like them (though with any luck that will change in due time). It's a real shame that only a few bikes to date are able to fit them."

Which rims for Big Apple?
I had the opportunity recently to set up my father's old Trek 850 with
a pair of 60-559 Big Apples. My normal bike is a Giant Reign 3 with 47-559 on the rear and 35-559 on the front (both kept around 40-50 psi), so I was interested to see how the 60mm tires compared to the Reign's suspension. I pumped the Big Apples to around their minimum recommended pressure so they would give me the very soft ride, but on the really poorly kept roads I was riding them on, it was still quite a bouncy ride. I couldn't ride at my normal 30kph off curbs and over pot holes without getting out of the seat. Also at that pressure there was noticeable bounce when I put a lot of force into the pedals. So maybe compared to very short travel suspensions they might be an adequate substitution, but they're nothing like a nice FS bike. |

For a noticeable suspension you need to go very low on pressure. The front handling is very poor then. Lou |

Anyone with experience of Scwalbe's Big Apple tyre? Yep. I've used 60-559, 60-622, and 50-622 sizes extensively, and I have some experience with the 60-406 size. For the purposes of this discussion I'm going to limit myself to commenting on the 60-559 and 60-622 sizes, since they are the ones that really stand apart from the usual selections in those rim diameters. I'd only use the 50mm versions if my bike was unable to fit the 60mm ones. 1.Is it true that the Big Apple is a good substitute for a suspension fork and a suspended setpost? Yes, in that they can attenuate shocks to a similar degree (similar to a telescopic seatpost, anyway). But you have to run very low pressures to get that sort of benefit from them, and how low you can safely go depends on how wide your rims are. I weigh about 350 lbs., and I can run these tires on relatively crappy city streets at 2 bar, or about 29 psi. I have had no pinch flats to date at such pressure. Rolling resistance at 29 psi is surprisingly OK; while I'm sure it is slower than at the tires' max 65 psi rating, I don't notice a speed difference. I only notice a difference in cushiness and in handling/traction. 2. What size tyre? What size rim? What make rim? My favorite size of the Big Apple is 60-622 or 29 x 2.35". Between the width of the tire, the flexibility of the tire, and the diameter of the wheel, I've found no better ride quality in the cycling world. It bridges gaps, absorbs bumps, steps up gently onto raised edges, and finds a secure footing on irregular surfaces like no other street tire. I've run the 60-622 Big Apple on three kinds of rims: Mavic T519 (an ordinary touring bike rim), Sun Rhyno Lite 700c (a 27.5mm wide MTB rim) and Kris Holm 29er mountain unicycle rim (a 38mm wide downhill- style rim). Not surprisingly, it works best on the widest rim. It is on the 38mm wide rim that I can use sub-30 psi pressures without noticing any lateral casing deflection in hard corners. The Sun Rhyno Lite is almost as good in that regard, but mounted on the Mavic rim the tire is significantly less stable at high lean angles. However, the tire's shock absorbtion seems slightly better at any given pressure when the tire is mounted on the narrower rim. http://www.unicycle.uk.com/shop/shop...?catalogid=674 http://www.ebikestop.com/sun_rhyno_l...lve-RM8438.php 3. What size rim would in your opinion be better? Diameter? 700c, no question. 4. Anyone else with an opinion of what width and which make of rim would be best for Big Apple in 50mm and 60mm widths? Width? Something wide; I'm not sure it matters all that much. I understand that there are a lot more wide stadtfiets-type rims available in Europe than there are here in the States. Anything from 622-20 on up should be appropriate. In the USA, that pretty much limits the choices to just the Sun Rhyno Lite 700c and the Kris Holm 29er. For 26" rims, the choices get a lot more accommodating. Sun Metal alone offers the Rhyno Lite, Rhyno Lite XL, Mammoth, King Pin, Double Wide, Single Wide, Double Track, and probably others that are all 559-21 or wider. There is a bewildering proliferation of wide rims intended for downhill and jumping MTBs, but many of these have no brake tracks and must be used with hub brakes. For best ride quality, I would not bother with any rim wider than about 559-35. Chalo |

For a noticeable suspension you need to go very low on pressure. The front handling is very poor then. For good handling, ride quality, and traction at low tire pressures, the rim width must be a good match to the tire width. When the inside width of the rim is about half of the tire's inflated width, the tire should be quite stable at any ridable pressure while still allowing decent compliance over bumps. At the same time, the soft tire's ability to conform to the contours of the ground surface provides additional traction. I have a mountain bike fitted with 26 x 3.0 siped slicks mounted on 45mm wide rims. Despite my approximately 350 pound weight, I can run these tires at 16-18 psi for a very soft ride. At the same pressures, the traction this bike offers in corners is superior to that of any other bike I have ridden. Sometimes I use higher pressures up to 40 psi to diminish rolling resistance, but there are no discernible handling benefits from doing so. Chalo |

My every day/commute bike has 2-inch (50-559) Schwalbe Marathon tires, which are similar to the Big Apple. Although fine on unpaved roads, there is still much more vibration/shaking compared to my mountain bike with front suspension fork. But compared to my old commute bike with 700x28C, the wider tires are far more comfortable (and also safer, I think), and in the city I don't worry about potholes or a tire getting caught in tram tracks. Any difference in speed or rolling resistance is so minor that I don't notice it. So 25 years later I have overcome my indoctrination by Eugene Sloan's "Complete Book of Bicycling". Ned |

I often had comments from roadies on how wide my 32-406 tires were, so I of course replaced them with 47-406 tires for better ride, traction, handling and decreased rolling resistance. -- Tom Sherman - Holstein-Friesland Bovinia The weather is here, wish you were beautiful |
