Stahlrahmen Rennrad für Nica @ BRC

March 23, 2017 Uncategorized 0 Comments

Super excited about this bike as it represents the beginning of the Big Forest Frameworks Factory Racing team! I built the steel road frame for Nica who rides for BRC Endspurt road racing based in Berlin. Nica has been racing and winning in her class the past few years, she happens to be a fan of steel road bikes, and I’m really looking forward to seeing what she can do this season on this bike.

The frame is a fillet brazed mix of Columbus Spirit and Life tubing, most of the tubes are shaped in some way to improve performance and get the look I wanted for this road bike. The opposed bi-oval down tube improves stiffness at the bottom bracket shell as well as the head tube, leading to improved power transfer and quicker, more responsive steering performance. It also gives the impression of a larger diameter tube, without increasing weight, and this steel frame has a feeling of flow from front to back along the bike. The tapered head tube allows the use of a tapered steerer fork, saves weight compared to a straight head tube, and looks great, too. Even the top tube is tapered, with a 32mm diameter at the front, and 28mm at the rear, eliminating the need for a lug at the seat cluster.

It has a quite a few nice touches. You’ll find the Big Forest Frameworks tree in brass, brazed to the seat tube. The frame number, which Nica picked herself, is also stamped in brass and brazed to the inside of the non-drive side chain stay. And, the brass doesn’t stop there, I really love look and functionality of the brass cable adjusters on the down tube. Not everything is brass, though, here you’ll also find my signature stainless steel adapters on the seat tube for the front derailleur and the seat post clamp. These keep the finish (black metallic by the way, with a white panel and red tree, which are BRC Endspurt’s team colors) looking good over the years, and also increases the tube diameter to a standard 31,7mm. Using a smaller diameter seat tube with a standard 27,2 post saves weight and improves comfort, transmitting less road shock to the rider.

The road bike is finished off nicely with a Campagnolo Chorus groupset (looks great on a steel road bike!), 3T fork, stem and seat post, 50/60mm carbon tubular wheels, and gradient bar tape from Cinelli. Looks great and can’t wait to see what Nica will do on this bike this season!
