BIKE TEST - Transition Bikes
BIKE TEST STEVE JONES Words Photos v i c to r l u c a s O wners Kevin Menard and Kyle Young together with employee Sam Burkhart came over to Dirt last summer en route to Eurobike. They brought a load of TR450’s, did a load of riding, before hitting the local boozer. Very often time constrains such evenings, but on this occasion we’d got to know Transition quite well. They are totally committed to mountainbiking. In a short space of time Transition Bicycle Company has come some way. Based on the west coast of the USA in Ferndale, Washington, not far from where the Twilight, New Moon movies were shot, it is said to have some incredible riding. This then is where the bikes are developed. Deep in the On that occasion it had also been possible to get a first ride on the 450. But the story goes back a lot further than that. Ed here in the office had spotted the Transition many months before and everyone here was massively impressed with the clean lines, good angles and well thought graphic. The 450 looked every inch a race bike. Which it certainly is, represented well by racers Lars Sternberg and Bryn Atkinson (and lets not forget Jill Kintner) both in the US and internationally. As with many of their designs this bike is based around a link driven single pivot. The shock is mounted low in the frame and the nature of the suspension is 94 dirt magazine dirt magazine 95 SIZING, ANGLES AND NUMBERS There have been many good downhill bikes coming on to the market over the past few years, however one key area in which some have failed is in sizing. Transition have sized well on the 450, but most importantly have a good range. In terms of numbers, a reasonably low bottom bracket, ranging from 13.75” through 14.25”, when matched with low bar height and well–sized downtube gives the 450 a good riding position. A 47.5” wheelbase is good on the large and the head angle will fluctuate between 63º and 64º depending on the link setting. RIDDEN a progressive design, featuring a supple top stroke that leads into stronger mid to end stroke, there is said to be very little mid–stroke wallow. The even progression enables excellent tuning options and the bike comes with adjustable geometry, which can be achieved, via a ‘potato-chip’ in the linkage. Sound features. That well curved downtube has tooled reinforcement rather than a gusseted one, giving clean lines but also great strength. Double welding up front reinforces this. The 450 has a tapered head tube with integrated Cane Creek sized top headset bearing and 1.5” bottom. The height up front is super low on this bike due to the bearing and short headtube height. Overall the TR450 is an incredibly clean bike then, the lines are flowing and there is no place for mud build–up. The one–piece swingarm with internal cable routing, the protected linkage and shock, it all seems very simple, but yet few companies really get this near. Transition, in taking care to look at what some people might see as minor details have created a very strong package. In terms of hardware the bearings are pressed directly against post welding machined bearing seats inside the linkage. There are no worries of misalignment here and the whole rear end is beautifully put together. The 9.5” x 3” Fox RC 4 sits centrally amongst the triangles and is protected from mud and grit quite well by the linkage. Designed to be a bike to “be ridden hard and put away wet”. 96 dirt magazine Lets get the minus points cleared up first of all. We had a complete build direct from the US, and the Transition wheels and pedals on it were disappointing to say the least, we have now had two pairs of each and both have not been up to the punishment. The wheels need looking at very quickly and the pedals simply come loose. Something to think about if buying complete… actually, we’ve just heard that it will be ‘frame only’ here in the UK! One of the areas we struggled with the 450 was in set–up. At first we were quite disappointed with the ride and to be fair it has taken us sometime to get the set–up correct. At first we were getting way to much chassis feedback through the back of the bike and only after spending some time on the dials did we arrive at a happy point. This was a new bike and the RC4 did appear to loosen up after several days, so maybe the initial sluggishness out the back might well have been down to this. Once all set the angles on this bike add up when you get to ride it. It’s very much a stand and go riding position, one which very few bikes achieve. For that alone it scores massively. Adverse weight transfer once sorted was never an issue and balance in cornering is spot on. Everything about the 450 geometry shouts ‘RACE’. In terms of manoeuvrability, well, not being the lightest bike on the circuit, the complete test bike came in over 40lbs, might suggest a bit of a tank ride, but it’s not at all, and when you get used to this bike after a few runs it becomes second nature to pick up and drive. TRANSFER Spending some time on the suspension set–up is the starting point with the Transition because all the angles are ready for you to hammer. Lighter components would help to bring the bike in under 40lbs, which would also help. After many weeks the chassis is holding together well. Overall it looks amazing, rides positively and can probably deal with hammer and abuse a bit better than some of the skinny bikes currently on the market. z Price: £1899 frame & shock, S, M and L (no completes will be available in the UK) Surf Sales 01303 850 553 Colours: Racing Stripe Red, Racing Stripe Yellow or White www.surf-sales.com
