| | Bianchi Pista: Stiff as fuck, how do I make it softer? The title pretty much self-explantory, after selling the Peugeot fixie, I decided to upgrade and get a Bianchi Pista (first choice was the Charge Plug, but I can't seemed to find one in stock around London, evens Evans!), since I did not feel like building another one again, I knew it gonna be quite stiff since the Pista is a proper track bike, but damn nothing prepared me how really stiff it is, since there's nothing I can do about the stiff frame, but does other compound such as wheels can able to make the ride less stiff? riding from Islington to Wimbledon on a newly built bike (even with plastic pedal) already gave me a very sore shoulder (thought breaking my previous record with just 43 minutes from Islington to Wimbledon on the Pista is a plus!). and none of those saddle suspension shit please. |

| | Hey Ed, I think that's spot on. Really take some time to position your stem, handlebars, post, and saddle. If you don't know how to fit your bike to you get some help. Sore shoulder could be from obvious things like your bag or how you slept too. Otherwise thinner rims tend to be less stiff I believe and can soften the ride quite a bit. Also don't under estimate vibration. Getting good bar tape/grips and/or gloves can stop your nerves and muscles in hands, arms, shoulders, and upper back from over working. |

| | I'm 6'1 and the frame is 57, which I think is an idea height, The handlebar gonna get changed to either a riser or bullhorn (bullhorn's probably better for skid stop in confident) as currently it have those track dropbar which is fine, but not easy to use on road. rat, the old MTB stem is too big, I'll try the handlebar first before getting a need stem, the tips of the stem, handle, post and saddle is great, and defintely save me some money in buying some carbon fibre seatpost, thanks for that, really. |

| | someone (winston?) said a basic way of gauging saddle height is to sit on the saddle, and put your heel on the pedal. your leg should be fully extended when the crank is at the bottom of the stroke. This means that when your foot is on the pedal as it normally is while cycling, your knees remain bent and your hips aren't stressed. I tried this and found my saddle was a tiny bit too high, made a pleasant difference. ...On second thoughts this does not really explain shoulder pain! I swapped out the track drops on my pista for risers fairly sharpish - they look nice but they're a bit uncomfortable for road use, especially after a longish ride. Bullhorns are a good idea. Oh, and if your MTB stem doesn't fit, it's probably a 1 1/8th inch stem (pista is 1inch threadless). You can easily get a shim to fit over the top of the steerer tube that will accomodate the wider stem. Which shoulder are you getting pain in? What kind of backpack are you using? It may not be the bike at all! :) |

| | I recently swapped saddles on my paddy wagon from the piece of crap WTB saddle. I stuck on a charge saddle and it yielded a somewhat more comfortable ride, although it feels a bit too wide atm. May try a narrow B17. This is a difficult subject though as saddle comfort is so subjective... How about trying some 700c x 25's and letting some air out? |

| | I had a similar problem with a really rigid road bike, improved things a bit by fitting a smaller diameter seatpost (with a shim). Don't pretend to completely understand the physics/engineering of this but apparently a smaller diameter tube transmits less vibration so provides a degree of damping, anyway it worked. If you're going to buy a carbon seat-post anyway, consider buying a 25mm one with a shim instead of a 27.2mm one. I'm going to try to get to CM tonight, if I manage to get home first and actually get there this time I'll bring a spare seat-post and shim I have and you're welcome to borrow them to try out if you like :) |

I always thought it was heel on pedal, bottom of stroke, and leg is 'slightly' bent. | |

| | The best book for bike positioning (and general cycling health advice) is Andy Pruitt's Complete Medical Guide for Cyclists. He's generally considered the best in the world for cycle fit and gait analysis and the book has several chapters on how to fit the bike to you. Highly recommended. I think you can pick up copies on-line for about £5-8. |

My other bike, (dirt jumpy mtb thing) which I occassionally use for riding about aswell has 2.4 and 2.1 inch tyres on it. Mtb slick tyres tend to be 1.5 and they look fairly skinny and roll fast. I am sure you can get away with much fatter tyres than 25c basically, go for 35's even, as under inflating a narrower tyre will lead to problems. It will give you some give, even if the tyres are hard. Aside from that, id say just roll with it. Doing anything else would only bastardise your bike, you might aswell get an mtb if you want something more plush. | |

| | Titanium seatpost and stem. Though a stiff material, it has excellent vibration dampening qualities. One thing to remember, is not to attach one titanium object to another, as it can sometimes bind together, and it can take a miracle to release it. Your frame is chome molybdenum steel, so won't bind with titanium. Last edited by GA2G; 30th May 2008 at 13:07.. Reason: sp |

I rather like it actually, just let me skid the hell out of the Contis on it before switching back to the Bontrager one, it's cheap but grippy as hell. | |

| | Defo sounds like a positioning thing to me. One point to note, that hasn't been directly mentioned, is that it's not just the handlebar position (both in terms of length and height, relative to the saddle), it's also your saddle position relative to the pedals. Your saddle wants to be not too far back, but far enough so that you can just take your hands off the bars and stay in balance without toppling forward. This way, your bum carries most of the load and your arms and thus shoulders don't have to work hard at all. Once the saddle is set, then the handlebars fall into place. And, yes, 90psi in the tyres is a good idea! Courant |
