Will a Botragner race wheelset fit on my "vintage" Lotus roadbike which currently has 27" wheels? |
Will a Botragner race wheelset fit on my "vintage" Lotus roadbike which currently has 27" wheels? 3 things to consider: 1. wheel dia. Most of the time this will work. 700c rims are a little bigger the 27". But the tires are usually smaller and 27" bike forks usually have tons of room between tire and crown - same goes for the rear wheel. 2. hub width The front hub width has remained the same for many decades. However, in the past 20 years the rear hub widtth has increased from 127 to 130cm. I can't be sure if older pre 1970's bikes are narrower yet. This is due to moving from 5 to 10 cogs in the back over the years. I easily put a newer 130cm, 9 speed wheel on my older 127cm 7 speed bike. I moved the 7 speed cassette to the nine speed wheel and used a spacer to align it. Works perfect. 3. rear cogs If your Lotus has a freewheel now you will have to get the corrosponding cassette (I assume the wheels you want are newer cassette hub type) If you have 5 or 6 speeds now I'm not sure if a cassette was made or available. I'm certain 7 to 10 speed cassettes are available. If it has a cassette install on new wheel with a spacer. Ebay is a good place to pick up cassettes etc. Possibly. A 700c rim is 8mm smaller in diameter than a 27", so if you have 4mm of downward adjustment on the brake pads they'll work. The new rear wheel also has a longer axle than the old one. You can permanently spread the rear end of a steel frame to fit the bigger spacing, but you'll be fine just pushing the wheel in. The difference isn't that big. Unless you get the wheels for free, I would advise against it. 1) wheel's rim diameter is different which could cause brake reach issues and slight handling difference. 2) rear axle width is different so frame will need to be spread 3) rebuilding the wheels you have with new rims/spokes would keep bike 'vintage' Assuming that all the other things mentioned come out OK, don't forget you're losing a little ground clearance as well. I upgraded the wheels on a bike with 27" wheels to 700c rims and it was GREAT! The ride improvement was dramatic. With that bike it was not a difficult swap. |
