Effect of 26″ conversion on 2006 Bighit geometry
Great site. A quick one:
The Bighit 2003 came out standard with a 24″ rear wheel. I’ve changed the seatstay to accommodate a 26″ wheel and I use the most progressive (bottom) hole on the frame and position A on the shock link. How will this affect the headtube angle? I do a lot of DH and some “downhill” freeriding if I can call it that. I know with the 24″ rear wheel the slackest angle is 66.3 degrees, but I’m concerned it has negatively impacted that angle. I have a 2004 Boxxer Team up front – 7″, and a Fox Vanilla RC at the back.
I raced that bike for a couple seasons. Loved it. I’m sure it’ll be even better with a full sized wheel.
I think that change will steepen your head angle by about 1.2 degrees, theoretically to about 67.5 degrees. These days that would be considered a good “freeride” head angle.
Real quick, here’s how I attacked that question:
I’d like to know what Adrian did to change the seat stays. I’ve been trying to figure a way to put a 26″ on my brother’s Bighit for a while now. Great site. Thanks, Don
Thanks for a prompt reply, Lee.
Don, I bought the bike used from a friend who had the conversion done somewhere in the USA (I live in Cape Town – South Africa)by Specialized themselves I believe. I can send you a photo of the 26″ seatstay, but I’ll need your e-mail address.
Thanks Adrian, would it possible for you to post some pictures on Freeridesouth.com rather than posting my e-mail address. Thanks for the info I’d love to see it. Don
Will do. Keep a lookout. I’m busy rebuilding my bike, but that will only allow for better photos.
I submitted the photo’s under the “rider” section for some unknown reason. Check them out there. Hope they help.
Thanks, I’ll have to check with Specialized. Once you get it built I’d like to see it complete. Thanks, again, Don
I think that 26″ conversion was aftermarket.
Those look like 2000 Specialized FSR team dh seatstays!
Lee, I agree with you about the tire. He’s just trying to find something a little more pedal friendly. I think it gonna end up being a Enduro.
Those stays where produced by a company in the UK called BETD. I looked into them for my old 03 BigHit Expert, they were pricey. Actually i memory serves me correctly, the stays did not alter the geometry by design.
>> the stays did not alter the geometry by design
That would be clever. The BigHit was a great-handling bike.
