The BH Prisma is packed with some of the latest and greatest cycling technologies on the market. Designed to be a true all around bike, the BH Prisma uses cutting edge cycling tech like a Press fit BB30 bottom bracket that allows the Prism...
Strengths: The frame. Geometry is excellent and comfortable on all my rides...... up to approx 100 miles.
Very stiff when you stand up and hit the pedals hard with no notable flex. Light frame is well worth uprading the kit on it. Real strength lies in the climbing, being so compact every pedal stroke just sends you gliding up the inclines. The looks of the bike with its matt paint finish really catches the eye.
Weaknesses: House brand Titan kit isn't the most pleasing on the eye. Steering can feel twitchy at first (having ridden a Bianchi for 4 years, see review) but you grow into this bike and you suddenly regard it as responsive.
Tyre clearance is only really suited to maximum 23 mm rubbers. So close is the clearance that the flashing nipples on new tyres will polish the inside of the forks, you've been warned, nip them off first.
The FRAME is fantastic. I bought a 105 spec with house brand finishing kit, FSA Gossamer cranks and FSA SL280 Seatpost. Shimano RS20 wheelset. £1400. Immediate impression after riding a Bianchi AluCarbon Via Nirone for 4 years was the smooth ride, soaks up the ripples and bumps like I never imagined. My version started with a weight of just under 19 pound but with careful well spent sale day upgrades its now 16 pound which is, in my mind, incredible. Yes, there are many much lighter bikes out there, but they'll cost you a hell of a lot more than the £2500 mine has cost so far.
For the record mine is currently kitted as follows;
Original frame and forks.
Ritchey WCS Logic 2 bars, stem and seat post.
FSA K-Force Compact Crankset.
Rolf Prima Aspin SL wheelset.
Selle Italia SLR flow saddle.
Vittoria Corsa Evo KS tyres.

I bought a BH Prisma 2011 model some weeks ago and I am still amazed. I'm riding it with full Campagnolo Athena and Campagnolo Vento Reaction wheels. The Prisma is far from being the most expensive bike from BH but still very stiff, light, responsive and climbs like a goat! I'm really happy with this bike so far and I'd definitely buy it again. :)

Strengths: Latest tech: BB30, tapered steerer, carbon dropouts. KILLER looks! Tall head tube without the typical dorky look of 20mm of head tube above the top tube.
Weaknesses: My BH Prisma is the Brit-specced 7.8 Ultegra version (purchased from Wiggle), and the bar, stem, and seatpost are "Titan," a brand unknown to me, but they seem pretty plebeian compared to the excellent Ultegra shift system and brakes. The FSA Gossamer crank also seems kinda low-end by comparison. The Shimano RS10 wheels seem very high quality and look great, but are on the heavy side.
This is my first-ever carbon-framed bike, and only my 2nd road bike since returning to road riding after a 20-year hiatus. The bike this is replacing is a massively-upgraded Trek 1500, and the BH has really taken some getting-used-to. The biggest difference (and the one that nearly did me in) is the steering. The Trek's steering is slow and steady--you have to lead the bike around corners. By contrast I would describe the steering on the BH as "eager"--you just THINK about cornering, and the bike is already halfway around the bend!

Bike Setup: I swapped some of my favorite parts from the old Trek onto the Prisma: American Classic Sprint 350 wheels, Syntace Racelite carbon handlebar, FSA OS-99 stem, Selle Italia SLR saddle. With a SRAM Red 11-23 cassette and the stock 50-34 compact crank I get a higher high and a lower low than I got with the Dura Ace 12-25 cassette and 53-39 crank on the Trek.

Strengths: Good mix of stiffness and comfort, great looking paint. BB30 and tapered fork, Ultegra group inc brakes. Great build and packaging by Wiggle
Weaknesses: house brand stem, bar and seatpost, Shimano RS10 wheelset, Rubena tires, FSA Gossamer bb30 crank
great deal on closeout from Wiggle.com in the UK, $100 to ship to the US. This is for the Prism 7.8 with Ultegra. Not as nicely spec'd as the US version, but a great deal.
I just picked up a pair of these, and they're a bit lacking in instructions, and the DMT web site wasn't much help. Any idea what the cryptogram on the insole is indicating? And thinking about these more, seems like since the spring tension screws are used to mount the cleat to the shoe, they're b ... Read More »
I'm not necessarily a beginner. Use to road ride some 20+yrs ago. I've been a MTB'er for a long time. Last year I decided to get back into road riding to supplement my MTB'ing. Last year I picked up a used '05 Trek 1200 to see if I'd enjoy road'ing again.
Well after 1 summer, I got rid of the ... Read More »
